Description

TECHNICAL FIELD The present invention relates to a device for reducing the burden on a surgeon, which reduces the load imposed on the surgeon by protective clothing that protects the surgeon from radiation.

Conventionally, there has been known a device that reduces the burden on a surgeon by means of protective clothing that protects the surgeon from radiation (see, for example, Patent Document 1). The device of US Pat. No. 4,800,002 includes a fixed steel frame, a movable armset and a load hanger. Fixed steel frames are fixed to ceilings, steel beams and walls. The movable arm set is configured by continuously connecting both ends of a plurality of interlocking arms so as to be rotatable in a substantially horizontal plane.

One end of the moveable arm set is pivotally connected to the fixed steel frame and the other end holds the load hanger pivotally in a horizontal plane. A lead garment is hung from the load hanger, and the surgeon can wear the lead garment and move within the range of extension of the movable armset. During this time, the support of the load hanger reduces the load the lead garment imposes on the surgeon.

The device also includes one telescoping set piece between the movable armset and the load hanger. The telescoping set component includes an inner rod pivotally connected to the movable armset and an outer rod pivotally connected to the load hanger, the outer and inner rods being configured to telescope relative to each other. The outer and inner rods are provided with a plurality of corresponding orientation holes.

The height position of the load hanger can be adjusted by selectively inserting one orientation pin into the orientation hole to extend or contract the lengths of the outer rod and the inner rod.

Utility Model Registration No. 3175917

However, since the apparatus of Patent Document 1 has a structure in which protective clothing is suspended from the ceiling and held, construction work is required to install the apparatus in an operating room or the like, and handling is difficult. In addition, although the height position of the load hanger is adjustable, the adjustable range is narrow, so it does not allow the surgeon to perform surgery in a sitting position.

Also, it is difficult for the surgeon to bend forward because the protective clothing on the load hanger remains vertically extended at all times. Therefore, this device cannot be applied to surgeons performing surgery.

SUMMARY OF THE INVENTION In view of the above problems of the prior art, it is an object of the present invention to provide an apparatus for reducing the burden on a surgeon, which can reduce the burden imposed on the surgeon by the protective clothing while ensuring a high degree of freedom of posture for the surgeon.

As a result, the weight obtained by adding the weight M2 to the weights of the second and third arms 5 and 6 and the hanger portion 7 and the biasing force F1 applied to the first and second arms 3 and 5 by the first biasing means , and the biasing force F2 applied to the second and third arms 5 and 6 by the second biasing means 16 is balanced. Accordingly, the obtuse angle α formed by the first and second arms 3 and 5 and the obtuse angle β formed by the second and third arms 5 and 6 also present new angles.

As a result, the weight M2, which is a significant portion of the weight M1 of the protective clothing 24, is supported by the device 1 for reducing the burden on the surgeon. Therefore, the weight of the protective clothing 24 borne by the surgeon 2 is the value obtained by subtracting the weight M2 from the weight M1 (M1-M2), so that the burden of the protective clothing 24 on the surgeon 2 is considerably reduced. different.

After wearing the above-described headset 26 and VR glasses or smart glasses 29, the surgeon 2 puts on the cloak 31 and the gloves 32, as shown in FIG. 5, to complete preparations for treatment. At this time, the mantle 31 is put on so as to cover the device 1 for reducing the burden on the surgeon.

When the surgeon 2 starts treatment such as surgery and bends forward, as shown in FIG. As the distance to the front end of 6 increases, the obtuse angles α and β increase. For example, the obtuse angle α is 180°, which exceeds the obtuse angle.

As a result, the biasing force F1 applied to the first and second arms 3 and 5 by the first biasing means 15 has a greater force (pulling force) in the direction of decreasing the obtuse angle α. The biasing force F2 applied to the second and third arms 5 and 6 decreases in the direction of increasing the obtuse angle β (pressing force).

As a result, the biasing forces F1 and F2 as a whole act to make it easier for the surgeon 2 to bend forward and to facilitate the maintenance of the forward-bent posture. That is, since the spring constants of the first and second biasing means 15 and 16 are set so as to realize this action, the first and second biasing means 15 and 16 are designed so that the surgeon 2 can The protective clothing 24 does not change the load applied to the surgeon 2 when assuming a stooped posture, or functions to reduce the load.

In addition, the air in the mantle 31 is kept clean by the air purifier 22, and the air is sent to the surgeon 2 by the electric fan 21 to relieve the hot weather. This keeps the environment inside the mantle 31 comfortable during surgery.

As described above, according to the present embodiment, the force applied by the first and second biasing means 15 and 16 is applied to the protective clothing 24 via the second and third arms 5 and 6 and the hanger portion 7. The force exerted by the protective clothing 24 on the surgeon 2 can be reduced, even when the surgeon 2 bends forward. Therefore, the load imposed on the surgeon 2 by the protective clothing 24 can be reduced while ensuring a high degree of freedom in the posture of the surgeon 2 .

In addition, the first urging means 15 that can apply a necessary urging force by a strong tension spring is constructed, and the gas spring is small and lightweight, and a constant spring force can be obtained over a wide range of strokes, and there is no need for maintenance. The second urging means 16 can be configured by making use of.

In addition, since the attached portion is composed of the chair 4 with the casters 8, it is possible to always reduce the burden on the surgeon 2 due to the protective clothing 24 while coping with the movement and changes in posture of the surgeon 2.

Moreover, since the bottle installation part 20 for installing the bottle 19 for hydration is provided, the surgeon 2 can replenish water as needed.

In addition, since the first arm 3 is provided with the electric fan 21, it is possible to send air to the surgeon 2 to relieve the hot weather and maintain a comfortable operating environment for the surgeon 2. - 特許庁

Further, since the air purifier 22 is provided on the rear side of the chair 4, the air inside the mantle 31 can be kept clean and the surgeon 2 can be prevented from being infected.

Further, the arm support portion AS supports the lower end portion of the first arm 3 so that the first arm 3 can rotate about its axis and tilt in the left-right direction within a predetermined angle range. Therefore, the first to third arms 3, 5, 6, the hanger portion 7, and the protective clothing 24 are rotatable about the axis of the first arm 3 and tiltable in the left-right direction. The surgeon 2 wearing the garment can perform surgery while controlling his or her own posture with a higher degree of freedom.

The mounting portion 23 is for detachably mounting the arm support portion AS to the rear portion of the chair 4. Instead of the arm support portion AS, the backrest for supporting the back of the surgeon 2 is attached to the chair 4. Therefore, when the surgeon 2 seated on the chair 4 performs an operation that does not require the protective clothing 24, the backrest can be used instead of the device 1 for reducing the burden on the surgeon. By attaching it, the posture of the surgeon 2 can be appropriately assisted.

Further, the hanger section 7 is detachably provided with a thyroid guard TG for protecting the thyroid gland of the surgeon 2 from radiation. 7's thyroid guard TG can provide radiation protection.
