DETAILED DESCRIPTION

The present invention is now further described in conjunction with the accompanying drawings. For ease of description, the following embodiments take the direction toward the head position as "front" and the direction toward the leg position as "rear". The positional relationship between "front" and "rear" does not constitute a further limitation of the present invention.

Referring to FIG1 , FIG1 shows an electric operating table according to an embodiment of the present invention, which mainly includes a base, a table top, an inclination adjustment device, and a head plate rotation mechanism and a leg plate rotation mechanism. The upper end of the lifting column is connected to the lower end surface of the table top through the inclination adjustment device, and the inclination adjustment device drives the table top to rotate left and right and up and down.

Preferably, the connection point between the upper end surface of the lifting column and the lower end surface of the table is biased toward one end thereof to form a cantilever structure. The design of the cantilever structure enables the electric operating table to be inserted into the CT or X-ray equipment and enables C-arm radiography. The table top is preferably made of high-density plastic fiberboard that can penetrate radiation, so that human body parts can be quickly identified in the equipment for accurate medical examinations.

The upper and lower ends of the table are connected with a head plate and a leg plate through a head plate rotating mechanism and a leg plate rotating mechanism respectively. The upper end of the table is connected with the head plate rotating mechanism, which drives the head plate to rotate up and down; the lower end of the table is connected with two leg plate rotating mechanisms, which drive the left leg plate and the right leg plate to rotate up and down respectively.

Referring to Figures 2 to 5, the tilt angle adjustment device is composed of a front-to-back tilt mechanism and a left-to-right tilt mechanism. The front-to-back tilt mechanism includes a center beam and a front-to-back tilt hydraulic cylinder; the center beam is perpendicular to the center axis of the tabletop (set along the length direction), and the front end of the center beam is rotatably connected to the upper end of the lifting column through a horizontal rotating shaft; the front-to-back tilt hydraulic is set in the vertical direction, and the output rod above it can move up and down; the rear end of the center beam is rotatably connected to the upper end of the output rod of the front-to-back tilt hydraulic cylinder through another horizontal rotating shaft.

Furthermore, a rotating arm is provided on the left and right sides of one end of the middle beam, and the rotating arm is a vertical plate structure and is extended backward along the central axis of the table. The two rotating arms are provided with openings, and the left and right openings are respectively connected to the two ends of the horizontal rotating shaft through copper sleeves. The shaft body of the horizontal rotating shaft passes through the lifting column and is rotatably connected to the upper end of the lifting column through the bearing, so that the middle beam can also rotate around the horizontal rotating shaft.

Preferably, the rear end of the middle beam is provided with a forward and backward tilt bracket extending downward, and the forward and backward tilt bracket is located at the rear side of the horizontal rotating shaft and the rotating arm; in the initial state, the horizontal distance between the forward and backward tilt bracket (including another horizontal rotating shaft) and the horizontal rotating shaft forms a "force arm". The output rod of the forward and backward tilt hydraulic cylinder is extended from bottom to top, and the lower end of the forward and backward tilt hydraulic cylinder is rotatably connected to the lifting column through the hydraulic cylinder rotating shaft. The lower end of the forward and backward tilt bracket is rotatably connected to the upper end of the output rod of the forward and backward tilt hydraulic cylinder through the rotating shaft. Furthermore, the forward and backward tilt hydraulic cylinder drives the middle beam and the table top to rotate around the horizontal rotating shaft (as a fulcrum) by controlling the upward telescopic movement of its output rod, thereby realizing the adjustment of the upper and lower angles of the table top.

2 to 5 , the left and right tilt mechanism in the tilt adjustment device further adds left and right tilt functions on the basis of the front and rear tilt mechanism to form the technical effect of complete left and right and up and down angles of the tilt adjustment device, which includes a crossbeam and left and right tilt hydraulic cylinders.

The cross beam is arranged in parallel with the middle beam, and the cross beam and the middle beam are relatively rotatable to the left and right through the left and right tilt axes. The left and right tilt axes are arranged along the central axis of the table top and pass through the cross beam and the middle beam in sequence. In this embodiment, the left and right tilt axes are fixedly connected to the middle hole of the middle beam, and are rotatably connected to the middle hole of the cross beam through bearings so as to rotate around the axis of the left and right tilt axes. The upper end surface of the cross beam is connected to the lower end surface of the table top through a number of fixed connectors.

The left and right tilt hydraulic cylinders are arranged parallel to the cross beam and the middle beam, that is, perpendicular to the central axis of the table top. One end of the hydraulic cylinder is rotatably connected to the first rotating pin on the right side of the middle beam, and the other end of the hydraulic cylinder is rotatably connected to the second rotating pin on the left side of the cross beam.

Furthermore, a notch is provided on the right side of the crossbeam; the first rotating pin on the right side of the middle beam extends along the central axis toward the crossbeam direction (notch direction) and passes through the notch. When the left and right inclination angles of the table top are in a horizontal state, the first rotating pin is received in the space of the notch. A second rotating pin is provided on the crossbeam; the two ends of the left and right inclination cylinders are rotatably connected with the first rotating pin and the second rotating pin, respectively.

The left and right tilt hydraulic cylinder controls the extension/retraction of its output rod to push/pull the distance between the two rotating pins, thereby driving the crossbeam to rotate relative to the center beam to adjust the left and right angles of the table top.

Preferably, there are two crossbeams, which are respectively arranged in the front and rear directions of the middle beam. The left and right sides of the two crossbeams are connected by connecting plates to form a frame structure; the upper end of the frame structure is connected to the lower end surface of the table top, and the frame structure can make its connection with the table top more stable.

Preferably, the inclination adjusting device is provided with an inclination detecting unit for detecting the actual inclination state of the inclination adjusting device.

Referring to Figures 6 to 8, the head plate rotation mechanism includes a head plate frame, a head plate latch seat and a head plate gas spring. In this embodiment, the head plate frame includes two side frames located at the sides, and a cross frame is connected between the front ends of the two side frames to form a U-shaped frame, and the U-shaped opening faces the table top (rear).

The rear ends of the two side frames are connected to the head plate latch seat through the rotating shaft a (copper pin), and the rear ends of the head plate latch seat are fixedly connected to the front end of the table through the head plate latch; an extension portion is provided at the lower end of the head plate latch seat, and the end of the extension portion is rotatably connected with the rear end of the head plate gas spring through the rotating shaft b (copper pin), and the front end of the piston rod at the front end of the head plate gas spring is rotatably connected with the front end of the side frame through the rotating shaft c (copper pin). When in use, the piston rod of the head plate gas spring can be controlled to perform reciprocating telescopic motion along its axis. When the piston rod extends forward, the front part of the head plate frame is lifted up by the rotating shaft c, and the head plate frame rotates upward around the rotating shaft a; at this time, the head plate gas spring rotates upward synchronously around the rotating shaft b. When the piston rod retracts relative to the initial position, the front part of the head plate frame is pulled down by the rotating shaft c, and the head plate frame rotates downward around the rotating shaft a; at this time, the head plate gas spring rotates downward synchronously around the rotating shaft b. The above operation can achieve a rotation range of plus or minus 30 degrees to meet the needs of different angles, which not only facilitates the doctor's work, but also improves the practicality and comfort of the electric operating bed.

Preferably, the upper end surface of the head plate frame is provided with a head plate lining plate as a head table surface. Further, the head plate lining plate is preferably made of a high-density plastic fiberboard that can penetrate radiation, which can increase the X-ray penetration area to completely cover the head.

Preferably, it also includes a head plate gas spring head seat, and the front end of the piston rod is inserted into the opening at the rear end of the head plate gas spring head seat and fixed. The front end of the head plate gas spring head seat is rotatably connected with the side frame through the rotating shaft c. The head plate gas spring head seat serves as an intermediate sleeve structure, which can prevent the end of the piston rod from directly participating in the transmission, reduce its wear, and facilitate the maintenance of the equipment.

Preferably, a wrench (strip structure) is also provided on the front end surface of the head plate frame cross frame for easy manual operation. Preferably, the left and right outer sides of the two side frames of the head plate frame are also provided with head plate guide rails for sliding. The head plate set by the head plate rotation mechanism has the characteristics of convenient installation, simplified structure, simple operation, and stable and reliable, which can ensure that the range of angle deformation does not exceed 0.5 degrees, thereby ensuring stability and accuracy during the operation.

Referring to Figures 9 to 11, the leg plate rotation mechanism includes an upper leg plate frame, a lower leg plate frame, a leg plate gas spring and a connecting pin seat; the front end of the connecting pin seat is connected to the rear end of the table top through a latch, and its rear end is connected to the front part of the lower leg plate frame through a rotating shaft d. The extension of the lower end of the connecting pin seat is also connected to the front end of the leg plate gas spring through a rotating shaft e, and the front end of the piston rod at the rear end of the leg plate gas spring is connected to the rear end of the lower leg plate frame through a rotating shaft f; by controlling the extension/retraction of the piston rod, the lower leg plate frame is driven to rotate upward and reset.

The leg panel rotation mechanism enables the leg panel to have a larger rotation range, realizes the integration of the upper leg panel module and the lower leg panel module, effectively reduces the weight and simplifies the number of parts.

When in use, the piston rod of the leg board gas spring can be controlled to perform reciprocating telescopic motion along its axis. When the piston rod extends backward, the rear part of the lower leg board frame is lifted up by the rotating shaft f, and the lower leg board frame rotates upward around the rotating shaft d; at this time, the leg board gas spring rotates upward around the rotating shaft e synchronously. When the piston rod retracts, the front part of the lower leg board frame is pulled down by the rotating shaft f, and the lower leg board frame rotates downward around the rotating shaft d until it is reset. The above operation can achieve an upward rotation range of 30 degrees, allowing doctors to move the patient's legs more effectively. Preferably, the lower leg board frame is L-shaped, with its bent section facing inward; the upper end surface of the lower leg board frame is provided with a lower leg board lining as a leg table, and preferably a high-density plastic fiberboard that can penetrate radiation is used. The L-shaped structural design expands the X-ray penetration area in the middle, ensuring that the entire leg size of the patient can be fully covered for accurate imaging examinations.

Preferably, the upper end surface of the upper leg board frame is provided with an upper leg board lining serving as the upper leg portion table top; it is also preferred to use a high-density plastic fiberboard that can penetrate radiation.

Preferably, the outer side of the lower leg board frame is provided with a leg board guide rail for sliding.

The left and right leg boards set up by the leg board rotation mechanism can meet the needs of people with special body shapes, and can provide comfortable support in both width and length; they can be folded upward to a larger angle, allowing doctors to move the patient's legs more effectively.

Referring to Figure 1, the base is a box structure, the upper end of which is connected to the lower end of the lifting column through the column tube mounting plate, and the lower end of which is connected to a plurality of casters through the bottom plate, respectively, to improve the load-bearing capacity of the chassis. It is also preferred to change the original internal detection interface into an upward opening and closing structure to help maintenance personnel better detect and replace internal parts.

In summary, this embodiment achieves the requirements of front and back tilt, left and right tilt, and angle adjustment of the head board, leg board, etc. required for surgery through the tilt adjustment device, which facilitates the doctor's work and reduces fatigue. The above describes the implementation mode of the present invention in combination with the drawings and embodiments. The structure given in the embodiment does not constitute a limitation of the present invention. A skilled technician in the field can make adjustments as needed, and various deformations or modifications within the scope of the attached claims are within the scope of protection.
