Detailed Description
The invention aims to provide a surgical instrument and a driving locking structure thereof, which solve the problems that the locking effect of an end effector of the surgical instrument in the prior art is poor, and when the end effector contacts tissue, the tissue gives a reaction force to the end effector, so that the end effector swings and cannot contact the tissue at an optimal angle, thereby realizing anastomotic cutting of the tissue.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-18, fig. 1 is a schematic view illustrating an overall structure of a surgical instrument according to the present invention. The present invention provides a surgical instrument that includes a pull rod assembly 12, an end effector 13, and a handle assembly 14. The end effector 13 is disposed at an end of the pull rod assembly 12 remote from the handle assembly 14. The handle assembly 14 is disposed at the other end of the pull rod assembly 12. The present invention provides a surgical instrument that further includes a drive lock structure coupled to the pull rod assembly 12. The drive lock mechanism is used to control the rotation and locking of the end effector 13 relative to the pull rod assembly 12.
The pull rod assembly 12 includes a shaft sleeve 16 and first and second rods 121, 122 disposed inside the shaft sleeve 16. The handle assembly 14 includes a housing, a stationary handle, and a closure trigger that can be manipulated to position and close the end effector 13.
The end effector 13 includes a cartridge housing (not shown) for operably supporting a cartridge assembly (not shown) therein and an anvil (not shown) pivotally connected to the cartridge housing and selectively movable between an open position and a closed position. Specifically, the anvil is movably coupled to one end of the shaft sleeve 16 and is driven to pivot upwardly to open when the pull rod assembly 12 is moved in a direction away from the handle assembly 14 and to pivot downwardly to close when the pull rod assembly 12 is moved in a direction toward the handle assembly 14.
In use of the surgical instrument, the closure trigger is pressed toward the handle assembly 14, which drives the pull rod assembly 12 forward through the transmission mechanism to pivot the anvil downward to close the end effector 13 to position, clamp tissue. When the tissue to be treated is introduced between the cartridge seat and the anvil, the surgeon may press the closure trigger until it is locked, thereby bringing the anvil to a closed position, i.e., the end effector 13 is in a closed state.
As shown in fig. 2, 16-18, the pull rod assembly 12 further includes a first rod 121 and a second rod 122 disposed in parallel and spaced apart relation. The rotary disk 3 drives the first lever 121 and the second lever 122 to move in tandem through the first motion conversion member 5. The first rod 121 and the second rod 122 move in tandem and then drive the end effector 13 to rotate through the second motion converting member 15.
As shown in fig. 2, the first motion converter 5 includes a first slider 51 and a second slider 52. The first slider 51 is fixedly connected to an end of the first rod 121. The second slider 52 is fixedly connected to an end of the second rod 122. Optionally, a protruding clamping structure (not shown) is provided at the end of the first rod 121 and the second rod 122, a groove clamping structure (not shown) is provided at the corresponding positions of the first slider 51 and the second slider 52, and when assembled, the protruding clamping structure is clamped into the groove clamping structure, so that the first slider 51 is fixedly connected with the first rod 121, and the second slider 52 is connected with the second rod 122 similarly. A first receiving hole (not shown) is provided in an upper portion of the first slider 51, and a second receiving hole (not shown) is provided in the second slider 52. The lower end surface 303 of the rotary disk 3 is provided with a first connection post 31 and a second connection post 32, and the first connection post 31 and the second connection post 32 are symmetrically arranged with respect to the rotation center of the rotary disk 3. After assembly, the first connecting column 31 extends into and is accommodated in the first accommodating hole, and the second connecting column 32 extends into and is accommodated in the second accommodating hole, so that when the rotating disc 3 rotates, the first connecting column 31 and the second connecting column 32 move by taking the rotation center of the rotating disc 3 as the rotation center, and further abut against the hole walls of the first accommodating hole and the second accommodating hole, and the first sliding block 51 and the second sliding block 52 can be driven to move in tandem.
Thus, when the rotating disc 3 rotates in the first direction, the first connecting column is driven to move in the first accommodating hole, the second connecting column is driven to move in the second accommodating hole, so that the first rod 121 moves forwards and the second rod 122 moves backwards, and when the rotating disc 3 rotates in the second direction, the first connecting column is driven to move reversely in the first accommodating hole, the second connecting column is driven to move reversely in the second accommodating hole, so that the first rod 121 moves backwards and the second rod 122 moves forwards. Wherein the first direction and the second direction are opposite. The first motion converter 5 in this embodiment is simple in structure and reliable in operation. The rotation of the rotating disk 3 can be transmitted to the first lever 121 and the second lever 122 by the first motion converting member 5.
As shown in fig. 2, 16-18, the second motion converter 15 comprises a steering seat 8 and a steering sleeve 9. One end of the steering sleeve 9 is clamped with the steering seat 8, and the other end is fixedly connected with the end effector 13. The tie rod assembly 12 is connected to the end effector 13 via the steering seat 8 and the steering sleeve 9. Specifically, the steering seat 8 is provided with a third connecting column 81 and a fourth connecting column 82. The ends of the first rod 121 and the second rod 122, which are far away from the handle assembly 14, are respectively provided with a first connecting hole 123 and a second connecting hole 124.
The extending directions of the first and second connection holes 123 and 124 are perpendicular to the extending directions of the first and second bars 121 and 122. The third connecting post 81 is accommodated in the first connecting hole 123 and can move in the first connecting hole 123, so that the first rod 121 can rotate around the third connecting post 81, and the fourth connecting post 82 is accommodated in the second connecting hole 124 and can move in the second connecting hole 124, so that the second rod 122 can rotate around the fourth connecting post 82. The second motion converting member 15 converts a front-to-rear motion of the first and second levers 121 and 122 into a rotation of the end effector 13 in the first direction when the first lever 121 moves forward and the second lever 122 moves backward, and the second motion converting member 15 converts a front-to-rear motion of the first and second levers 121 and 122 into a rotation of the end effector 13 in the second direction when the first lever 121 moves backward and the second lever 122 moves forward. The second motion converter 15 in this embodiment is simple in structure and reliable in operation. By the second motion converting member 15, the tandem motion of the first lever 121 and the second lever 122 can be converted into the swing of the end effector 13.
As shown in fig. 2, 11 and 16, the present invention provides a surgical instrument having a shaft sleeve 16 disposed on the outside of the pull rod assembly 12. The shaft sleeve 16 has a tubular structure, and the first rod 121 and the second rod 122 of the pull rod assembly 12 are inserted into the tubes thereof. Second tooth structures 161 are provided on opposite sides of the interior of the shaft sleeve 16. The opposite outer sides of the first lever 121 and the second lever 122 are each provided with a first tooth arrangement 125. The second tooth structure 161 is engaged with the first tooth structure 125 of the first and second bars 121 and 122, respectively. Alternatively, the location, length or number of the second tooth structure 161 and the first tooth structure 125 may be selected by those skilled in the art according to the actual use situation. Alternatively, as shown in FIG. 16, the second tooth structure 161 and the first tooth structure 125 are positioned proximate to the end effector 13. It should be appreciated that the second tooth structure 161 and the first tooth structure 125 may be configured as multi-stage structures, for example, a section of the second tooth structure 161 is disposed at one end of the pull rod assembly 12 near the handle assembly 14, at a middle position, and at a position near the end effector 13, and the first tooth structure 125 is disposed at a position corresponding to the first rod 121 and the second rod 122, respectively, so that when the first rod 121 and the second rod 122 move back and forth in the shaft sleeve 16, the second tooth structure 161 is kept engaged with the first tooth structure 125, thereby enhancing the structural strength of the first rod 121 and the second rod 122, preventing the end effector 13 from shaking when contacting with tissue, and thus solving the problem that the tissue will react to the end effector 13, and the end effector 13 swings, so that it cannot anastomose and cut tissue at an optimal angle.
Further, as shown in fig. 2, 11 and 16, and 19-21, the present invention provides a surgical instrument having a third tooth structure 126 disposed on opposite inner sides of the first rod 121 and the second rod 122. A gear 17 is provided between the first lever 121 and the second lever 122. The gear wheel 17 is in engagement with a third tooth arrangement 126 of the first lever 121 and the second lever 122. Alternatively, as shown in FIG. 16, the gear 17 and the third tooth structure 126 are positioned proximate to the end effector 13. It is to be understood that the gears 17 and the third tooth structure 126 may be arranged in one or more sets. When the number of the gears 17 is plural, the plural gears 17 are disposed at equal intervals in the length direction of the tie rod assembly 12. For example, a set of gears 17 and third tooth structures 126 are provided at one end of the pull rod assembly 12 near the handle assembly 14, at an intermediate position, and at a position near the end effector 13, respectively, to achieve that the gears 17 and third tooth structures 126 remain engaged as the first and second rods 121 and 122 move back and forth within the shaft sleeve 16, thereby further enhancing the structural strength of the first and second rods 121 and 122, preventing the end effector 13 from rocking when in contact with tissue.
The surgical instrument provided by the invention is characterized in that the first tooth structure 125 is arranged on the opposite outer sides of the first rod member 121 and the second rod member 122 to be meshed with the second tooth structures 161 on the opposite sides of the inside of the rod sleeve 16, meanwhile, the gear 17 is arranged between the first rod member 121 and the second rod member 122 and is meshed with the third tooth structure 126 on the opposite inner sides of the first rod member 121 and the second rod member 122, so that the meshed tooth structures are added on the inner sides and the outer sides of the first rod member 121 and the second rod member 122, the structural strength of the first rod member 121 and the second rod member 122 is enhanced, and the deformation of the first rod member 121 and the second rod member 122 caused by the reaction force of tissues when the end effector 13 is contacted with the tissues is prevented, namely, the condition that the end effector 13 is not stable and accurate in the locking state and the like in the shaking or swinging position is avoided. The surgical instrument solves the problem that tissues react to the end effector 13, so that the end effector swings to enable the end effector to be incapable of anastomosing and cutting tissues at an optimal angle, and can meet specific operation requirements.
As shown in fig. 19-21, the gears 17 are arranged in a group and near the end effector 13 to engage with the gears 17 and the third tooth structures 126 of the first and second bars 121, 122. On opposite outer sides of the first and second bars 121, 122, a first tooth arrangement 125 is provided near the end effector 13. The first tooth structure 125 is spaced a greater distance from the end effector 13 than the third tooth structure 126 is spaced from the end effector 13. Second tooth structures 161 are provided on opposite sides of the interior of the shaft sleeve 16. Alternatively, the second tooth structure 161 may be an annular tooth structure, which is intended to be engaged with the first tooth structures 125 on the outer sides of the first rod 121 and the second rod 122 at the same time, so as to limit the first rod 121 and the second rod 122 and prevent the first rod 121 and the second rod 122 from bending and deforming.
To achieve immediate locking of the swing position of the end effector 13, the present invention also provides a drive lock structure for the surgical instrument for controlling rotation and locking of the end effector 13 of the surgical instrument, as shown in FIGS. 1-10 and 12-14. Specifically, the driving locking structure comprises a rotary knob 1, a steering shaft assembly 2, a rotary disc 3, an upper rotary head 4 and an upper cover 11. The steering shaft assembly 2 and the rotating disc 3 are coaxially arranged, and the steering shaft assembly 2 is used for driving the rotating disc 3 to rotate.
As shown in fig. 6, 8, 13, and 14, the steering shaft assembly 2 has a first end surface 201, the rotating disk 3 has a second end surface 301, and the accommodation groove 100 is formed between the first end surface 201 and the second end surface 301. Alternatively, the receiving groove 100 is located at the second end face 301 of the rotating disk 3. The receiving groove 100 has a locking groove 101 and a release groove 102. A locking member 6 is provided in the accommodation groove 100. The steering shaft assembly 2 rotates to drive the locking member 6 to move from the locking groove 101 to the release groove 102. When the locking piece 6 is located in the release groove 102, the steering shaft assembly 2 can drive the rotating disc 3 to rotate, and then the end effector 13 can be driven to rotate through the first motion conversion piece 5 and the second motion conversion piece 15.
The second end face 301 is provided with a lock actuator 7. The locking causes the moving member 7 to apply a force to the locking member 6 that moves or holds it in the locking groove 101. When the steering shaft assembly 2 stops rotating, the locking member 7 moves the locking member 6 into the locking groove 101, and the steering shaft assembly 2 cannot drive the rotating disk 3 to rotate. Specifically, the material of the locking member 6 is a ferromagnetic material, and the material of the locking member 7 is a magnetic material for attracting the locking member 6. The locking makes the moving member 7 disposed at a position close to the locking groove 101 for generating a magnetic attraction force to the locking member 6 so that the locking member 6 moves or remains in the locking groove 101 when no external force acts. Alternatively, the locking member 6 is a spherical ball made of steel, and the locking member 7 is a magnet block. The spherical balls are designed such that they facilitate movement within the locking groove 101 and the release groove 102.
Specifically, the accommodating groove 100 includes a first accommodating groove 103 and a second accommodating groove 104 which are symmetrically disposed. The locking member 6 includes a first locking member 61 and a second locking member 62. The first locking member 61 is accommodated in the first accommodation groove 103. The first locking member 61 is used to control the rotation and locking of the rotating disc 3 in the first direction. The second locking member 62 is accommodated in the second accommodating groove 104. The second locking member 62 is used to control the rotation and locking of the rotating disc 3 in the second direction. Wherein the second direction is opposite to the first direction.
When the first locking member 61 is located in the locking groove 101 of the first accommodating groove 103, i.e., in the locked state, the steering shaft assembly 2 cannot drive the rotating disk 3 to rotate in the first direction. When the first locking member 61 is located in the release groove 102 of the first accommodating groove 103, i.e., in a released state, the steering shaft assembly 2 can drive the rotating disk 3 to rotate in the first direction.
When the second locking piece 62 is located in the locking groove 101 of the second accommodating groove 104, namely in the locking state, the steering shaft assembly 2 can not drive the rotating disk 3 to rotate in the second direction, and when the second locking piece 62 is located in the releasing groove 102 of the second accommodating groove 104, namely in the releasing state, the steering shaft assembly 2 can drive the rotating disk 3 to rotate in the second direction.
That is, when the first locking member 61 and the second locking member 62 are in the release groove 102, if no other external force is applied, the locking member 7 will cause the first locking member 61 and the second locking member 62 to move from the release groove 102 to the release groove 101, and the first locking member 61 and the second locking member 62 need to overcome the force of the locking member 7 to move from the release groove 101 to the release groove 102.
Therefore, the locking force of the first locking member 61 and the second locking member 62 to the first locking member 61 and the second locking member 62 is applied by the locking making member 7 to be kept in the locking groove 101, so that the first locking member 61 and the second locking member 62 can be located in the locking groove 101 in time, at this time, the first locking member 61 and the second locking member 62 are blocked in the locking groove 101 under the action force of the locking making member 7 to realize wedge-shaped self-locking, and in this state, the front end of the end effector 13 cannot overcome the self-locking of the driving locking structure due to the stress of cutting anastomosis, so that the steering shaft assembly 2 and the end effector 13 are locked in time at the stop position, and the instant locking of the end effector 13 is realized.
As shown in fig. 13 and 14, a locking groove 105 is further provided between the locking groove 101 and the releasing groove 102. The width of the clamping groove 105 is slightly smaller than the diameter of the locking piece 6. By the design of the detent 105, the possibility that the locking member 6 will in some cases spontaneously move from the locking groove 101 to the release groove 102 can be avoided or reduced. These may be the case when the locking weakens the magnetic attraction of the moving member 7, the surgical instrument tilts, vibrates, collides, etc. By the design of the detent 105, stability of the locking of the end effector 13 can be increased.
Optionally, the groove wall on one or both sides of the detent groove 105 is an elastic protruding member (not shown). One end of the elastic protruding member is fixedly connected to the rotating disc 3 through an elastic member (not shown), and the other end extends into the accommodating groove 100. When the elastic groove wall of the clamping groove 105 is extruded, the elastic groove wall deforms towards the direction perpendicular to the groove wall, so that the width of the groove body of the clamping groove 105 is enlarged, and the spherical balls of the locking piece 6 can conveniently pass through. That is, when the lock making movable member 7 drives the lock member 6 to move from the release groove 102 to the lock groove 101, the lock groove 105 is pressed by the lock member 6 and deformed, so that the lock member 6 can pass through the lock groove 105.
In another alternative embodiment, the groove walls on one or both sides of the detent groove 105 are made of a deformable material. When the locking making moving member 7 drives the locking member 6 to move from the releasing groove 102 to the locking groove 101, the clamping groove 105 is pressed by the locking member 6 to deform, so that the locking member 6 can pass through the clamping groove 105. For example, the groove wall at the detent groove 105 is made of rubber. That is, when the lock making movable member 7 drives the lock member 6 to move from the release groove 102 to the lock groove 101, the lock groove 105 is pressed by the lock member 6 and deformed, so that the lock member 6 can pass through the lock groove 105. It should be understood that other detent structures may be provided by those skilled in the art, and the purpose of the detent structure is that the pressing force of the detent groove 105 on the locking member 6 is smaller than the acting force of the locking member 7 on the locking member 6, so that the locking member 6 can move into the locking groove 101 from the release groove 102 under the acting force of the locking member 7.
As shown in fig. 2-8 and 13, the first end face 201 of the steering shaft assembly 2 is provided with a driving member 208. The number of driving members 208 is 2. Alternatively, the driving member 208 is a column member. The 2 driving members 208 respectively extend into the accommodating groove 100 and can abut against the locking member 6. When the steering shaft assembly 2 rotates, the driving member 208 may push the locking member 6 to move from the locking groove 101 to the release groove 102. The 2 driving pieces 208 are arranged at intervals in the circumferential direction.
Specifically, the steering shaft assembly 2 has a disk shape, the other end surface of the steering shaft assembly 2 opposite to the first end surface 201 is provided with a center shaft 206, and the center shaft 206 is provided with a through hole 2061. During assembly, the central shaft 206 extends into the groove in the center of the rotary knob 1, and then passes through the fixing hole 18 and the through hole 2061 on the rotary knob 1 through the pin, so that the steering shaft assembly 2 is fixedly connected with the rotary knob 1, and when the rotary knob 1 is stirred, the steering shaft assembly 2 can be driven to synchronously rotate along the axis direction of the central shaft 206.
The first end face 201 of the steering shaft assembly 2 is provided with a drive block 202. A drive slot 302 is provided in the second end face 301 of the rotating disc 3. The drive slot 302 is configured to receive the drive block 202. The driving block 202 extends in the axial direction of the center shaft 206 at the first end face 201 of the steering shaft assembly 2 for controlling the rotation of the rotating disk 3. The driving block 202 includes a rotating portion 203 and a driving portion 204 connected. The turning portion 203 is provided at the center of the steering shaft assembly 2, the turning portion 203 has a circular arc-shaped mating surface, and the driving portion 204 has a planar driving surface 205. The driving portion 204 is disposed on a side of the rotating portion 203 away from the mating surface.
The drive surface 205 includes a first drive surface 2051 and a second drive surface 2052 that are coupled to respective ends of the mating surface, the first drive surface 2051 and the second drive surface 2052 being substantially parallel.
The steering shaft assembly 2 is an integrally formed component, and the driving block 202 and the driving member 208 thereof are integrally provided with the steering shaft assembly 2, or may be fixed by other connection means.
As shown in fig. 2 to 8 and 13, the second end surface 301 of the rotating disk 3 is provided with a driving groove 302 and two receiving grooves 100. The drive slot 302 is shaped as a groove similar to the drive block 202 for rotational engagement with the drive block 202.
As shown in fig. 8 and 13, when both locking pieces 6 are located in the locking groove 101, a first gap is formed between the first driving surface 2051 of the driving portion 204 and the groove wall of the driving groove 302, a second gap is formed between the second driving surface 2052 of the driving portion 204 and the groove wall of the other side of the driving groove 302, and the first gap and the second gap are symmetrical with respect to the driving portion 204. When the locking member 6 is positioned in the release groove 102, the first driving surface 2051 abuts the driving groove 302 or the second driving surface 2052 abuts the driving groove 302. When the first driving surface 2051 abuts against the driving groove 302, the steering shaft assembly 2 can drive the rotating disk 3 to rotate in the first direction, and when the second driving surface 2052 abuts against the driving groove 302, the steering shaft assembly 2 can drive the rotating disk 3 to rotate in the second direction. Wherein the second direction is opposite to the first direction.
Specifically, when the rotating portion 203 rotates along the first direction, the driving portion 204 rotates along with the rotating portion, so that the driving member 208 drives the first locking member 61 to move from the locking groove 101 to the releasing groove 102, in the process, the first gap disappears, and the rotating portion 203 rotates to drive the driving portion 204 to abut against the groove wall of the driving groove 302, so that the driving portion 204 drives the rotating disc 3 to rotate synchronously. That is, by designing the first gap, the locking member 6 is pushed to the release groove 102 during the rotation of the rotary knob 1, so as to unlock and release the end effector 13, and the swing angle of the end effector 13 can be controlled by continuing to rotate the rotary knob 1.
When the rotating part 203 rotates along the second direction, the driving part 204 rotates along with the rotating part, so that the driving part 208 drives the second locking part 62 to move from the locking groove 101 to the releasing groove 102, in the process, the second gap disappears, and the rotating part 203 rotates to drive the driving part 204 to abut against the groove wall of the driving groove 302, so that the driving part 204 drives the rotating disc 3 to rotate synchronously. That is, by designing the second gap, the locking member 6 is pushed to the release groove 102 during the rotation of the rotary knob 1, so as to unlock and release the end effector 13, and the swing angle of the end effector 13 can be controlled by continuing to rotate the rotary knob 1.
Thus, the first gap provides a space for the first locking piece 61 to rotate to release its locking, and the second gap provides a space for the second locking piece 62 to rotate to release its locking.
The steering shaft assembly 2, the rotating disc 3 and the rotary dial 1 can be directly assembled in the shell, and the driving locking structure provided by the invention aims to fix and limit the steering shaft assembly 2 and the rotating disc 3 so as to realize the rotating function. In a specific embodiment, as shown in fig. 2-4, an upper rotator head 4 and an upper cover 11 are also provided. The upper rotating head 4 is arranged on the outer shell of the surgical instrument, and the upper rotating head 4 and the upper cover 11 are fixedly connected through a buckle. A receiving cavity is arranged between the upper rotary head 4 and the upper cover 11 for assembling the steering shaft assembly 2, the rotary disk 3 and the rotary knob 1. When assembled, the steering shaft assembly 2 is provided with a central shaft 206. The rotary knob 1 is provided with a fixing hole 18, and a central shaft 206 extends into a groove of the rotary knob 1 after passing through the upper cover 11. The central shaft 206 is provided with a through hole 2061 and the rotary knob 1 is provided with a pin. The pin is inserted through the through hole 2061 to connect the rotary knob 1 with the steering shaft assembly 2.
In another embodiment, as shown in fig. 22-27, the receiving groove 100 is defined by the rotating disk 3 and the rotating disk retainer 33. Two grooves are symmetrically formed in the upper part of the peripheral side of the rotary disk 3, and a rotary disk stop ring 33 is sleeved outside the peripheral side, so that the rotary disk stop ring 33 can surround the grooves, thereby forming two accommodating grooves 100 (namely a first accommodating groove 103 and a second accommodating groove 104).
Alternatively, the steering shaft assembly 2 may be provided with a groove at a position corresponding to the receiving groove 100, and the groove of the steering shaft assembly 2 and the groove of the rotating disc 3 and the rotating disc stop ring 33 together define the receiving groove 100.
In the illustrations of fig. 22-27, the locking member 6 may be a magnetic member in the shape of a cylinder. Correspondingly, a lock-up actuating member 7 may be installed in the lower side surface of the steering shaft assembly 2 to generate an attractive force to the lock-up member 6. The cylinder-shaped locking piece 6 can prevent the locking piece 6 from rolling back and forth to provide locking stability, and meanwhile, the steering shaft assembly 2 and the rotating disc 3 are simpler in structure and convenient to process and produce.
In the drawings shown in fig. 22 to 27, other components may be referred to the illustrations in the drawings and the descriptions in the foregoing embodiments, and those skilled in the art may understand the structures and functions according to the illustrations and the descriptions in the foregoing embodiments, which are not described in detail herein.
The invention provides a driving locking structure and a surgical instrument, wherein the rotation and locking process of an end effector 13 is as follows:
When the rotary knob 1 is rotated in the first direction, the rotary knob 1 drives the steering shaft assembly 2 to rotate in the first direction, and the driving block 202 of the steering shaft assembly 2 rotates in the first direction until the driving portion 204 contacts one side wall of the driving groove 302, at which time the first gap disappears, and in the process, the driving piece 208 pushes the first locking piece 61 from the locking groove 101 to the release groove 102. At this time, if the rotary knob 1 is continuously rotated in the first direction, the rotary disk 3 is rotated in the first direction by the steering shaft assembly 2, at this time, the rotary disk 3 drives the first slider 51 to move forward through the first connection post 31, the first slider 51 drives the first rod 121 to move forward, and simultaneously the rotary disk 3 drives the second slider 52 to move backward through the second connection post 32, the second slider 52 drives the second rod 122 to move backward, and the first rod 121 moves forward and the second rod 122 moves backward, so that the end effector 13 rotates in the first direction. During the rotation of the rotary knob 1 in the first direction, the second locking piece 62 is always located in the locking groove 101 due to the magnetic attraction of the locking making moving piece 7, so that the locking of the rotation of the rotary disk 3 in the second direction is always maintained. When the rotation of the rotary knob 1 in the first direction is stopped, the first locking piece 61 is pushed against the locking groove 101 by the release groove 102 due to the magnetic attraction of the locking making the moving piece 7, and the locking of the rotary disk 3 in the rotation in the first direction is resumed. The first locking member 61 also pushes the driving member 208 and thus the steering shaft assembly 2 to rotate in the second direction together with the rotary knob 1 due to the magnetic attraction force until the first gap is restored to the state before the rotation of the rotary knob 1. In this way, the instant bidirectional locking of the rotating disc 3, the steering shaft assembly 2 and the rotary knob 1 at any position in the process of rotating in the first direction is realized, so that the end effector 13 is locked at the rotating angle corresponding to the any position, and the end effector 13 is prevented from undesirably rotating in any one of the first direction and the second direction at the rotating angle corresponding to the any position in the process of operation.
When the rotary knob 1 is rotated in the second direction, the rotary knob 1 drives the steering shaft assembly 2 to rotate in the second direction, and the driving part 204 of the steering shaft assembly 2 rotates in the second direction until the driving part 204 contacts the other sidewall of the driving groove 302, at which time the second gap disappears, and in the process, the driving piece 208 pushes the second locking piece 62 against the release groove 102 from the locking groove 101. At this time, if the rotary knob 1 is continuously rotated in the second direction, the rotary disk 3 may be rotated in the second direction by the driving of the steering shaft assembly 2, at this time, the rotary disk 3 drives the second slider 52 to move forward through the second connection post 32, the second slider 52 drives the second rod 122 to move forward, and at the same time, the rotary disk 3 drives the first slider 51 to move backward through the first connection post 31, the first slider 51 drives the first rod 121 to move backward, and the second rod 122 moves forward and the first rod 121 moves backward, so that the end effector 13 rotates in the second direction. During the rotation of the rotary knob 1 in the second direction, the first locking piece 61 is always located in the locking groove 101 due to the magnetic attraction of the locking making the moving piece 7, so that the locking of the rotary disk 3 in the first direction is maintained at all times. When the rotation of the rotary knob 1 in the second direction is stopped, the second locking piece 62 is pushed against the locking groove 101 by the release groove 102 due to the magnetic attraction of the locking piece 7, and the locking of the rotation of the rotary disk 3 in the second direction is resumed. The second locking member 62 also pushes the driving member 208 and thus the steering shaft assembly 2 to rotate in the first direction together with the rotary knob 1 until the second gap is restored to the state before the rotation of the rotary knob 1. In this way, the instant bidirectional locking of the rotating disc 3, the steering shaft assembly 2 and the rotary knob 1 at any position in the process of rotating along the second direction is realized, so that the end effector 13 is locked at the rotating angle corresponding to the any position, and the end effector 13 is prevented from undesirably rotating along any one of the first direction and the second direction at the rotating angle corresponding to the any position in the process of operation.
In summary, the surgical instrument of the present invention controls the rotation angle of the rotary disk 3, and thus the rotation angle of the end effector 13, by the cooperation between the steering shaft assembly 2, the rotary disk 3, the lock-up actuator 7, and the lock-up member 6. By rotating the rotary knob 1, the rotary disc 3 is rotated to different positions, thereby rotating the end effector 13 to different positions. By the cooperation of the locking piece 7 and the locking piece 6, the rotating disk 3 is locked at any position in the rotating process, so that the end effector 13 is locked at any position in the rotating process, and the aim of accurately clamping target tissues can be achieved.
On the premise of realizing the instant bidirectional locking function of any position in the rotation process, the first tooth structures 125 are arranged on the opposite outer sides of the first rod member 121 and the second rod member 122 so as to be meshed with the second tooth structures 161 on the opposite sides inside the rod sleeve 16, meanwhile, the gear 17 is arranged between the first rod member 121 and the second rod member 122 and is meshed with the third tooth structures 126 on the opposite inner sides of the first rod member 121 and the second rod member 122, so that the meshed tooth structures are added on the inner sides and the outer sides of the first rod member 121 and the second rod member 122, the structural strength of the first rod member 121 and the second rod member 122 is enhanced, and the deformation of the first rod member 121 and the second rod member 122 caused by the reaction force of tissues when the end effector 13 is contacted with tissues is prevented, namely, the conditions that the end effector 13 is not stable and accurate in the locking state and the positions of shaking or swinging are avoided.
That is, the surgical instrument provided by the invention improves the control precision and stability of the swing angle of the end effector 13, solves the problem that tissues can react to the end effector 13, so that the end effector 13 swings to enable the end effector to be incapable of anastomosing and cutting tissues at an optimal angle, and can meet specific operation requirements.
