Technical Field
[0001] The utility model relates to a medical device, in particular to a device suitable for arthroscopic shoulder surgery, specifically an upper limb hand support plate for arthroscopic shoulder surgery. Background Art
[0002] During arthroscopic shoulder surgery, under general anesthesia, the patient will have a certain degree of loss of sensation. Therefore, the lateral position is mostly adopted, with the healthy upper limb of the patient abducted, and the angle between it and the longitudinal axis of the body is less than 90 degrees. Currently, a straight plate type upper limb hand support plate is mainly used, installed on one side of the operating bed, forming an "L" shape with the operating bed. However, during arthroscopic shoulder surgery, the surgeon needs to stand on both sides of the patient's head for surgical operations. At this time, the position of the upper limb hand support plate hinders the surgeon's surgical space, affects surgical operations, and increases the surgical difficulty for the surgeon. Moreover, it is not convenient for the circulating nurse during the operation to observe the puncture points for infusion and arterial monitoring of the healthy upper limb, easily causing unsmooth infusion and blood transfusion during the operation, and even seriously affecting the patient's anesthesia safety and surgical process.
[0003] Therefore, it needs to be improved to better meet the surgical requirements and improve the surgical quality. Summary of the Utility Model

[0021] The present utility model will be further described below in conjunction with the drawings and embodiments.
[0022] As Figures 1 to 4 shown.
[0023] An upper limb hand support plate for arthroscopic shoulder surgery, comprising a main support plate 1 and an auxiliary support plate 4.
[0024] The main support plate 1 is in the shape of a rectangular plate. A fixing rod 2 is provided on the bottom surface at one end thereof, and a slot 3 is provided on one side thereof. The fixing rod 2 is in the shape of a straight rod and can be connected to the operating bed frame for convenient connection.
[0025] The slot 3 is a long strip-shaped groove, the length of which is equivalent to the length of the main support plate 1. A slide groove 10 is respectively provided on the top surface and the bottom surface thereof. The slide groove 10 is a long strip-shaped groove, which is arranged parallel to the slot 3 and communicates with the slot 3, so that the slot 3 and the slide groove 10 form a cross-shaped structure in cross section.
[0026] A plurality of positioning holes 6 are provided on the top surface of the slot 3. The positioning holes 6 are evenly distributed along the length direction of the slot, and the spacing is about 2 cm, which can meet the positioning requirements. A relief groove 7 is provided on the bottom plate of the slot 3. The relief groove 7 is a through groove, which is arranged parallel to the slot 3, and its length covers the positioning holes 6.
[0027] The auxiliary support plate 4 is in the shape of a rectangular plate. Its length is slightly less than the length of the main support plate 1, its thickness is equivalent to that of the main support plate 1, and a connecting plate 9 is provided at one end thereof. The connecting plate 9 is in the shape of a short plate, and its thickness is slightly less than the width of the slot 3, so that it can be movably placed in the slot 3 and can move along the slot 3.
[0028] A through-hole-shaped mounting hole is provided in the middle of the connecting plate 9, and a roller 8 is provided in the mounting hole. The roller 8 can rotate on the vertical plane of the connecting plate, and the edge part thereof is located outside the top surface and the bottom surface of the connecting plate 9. At the same time, the outer diameter of the roller is adapted to the distance between the slide grooves, so that its edge can be placed in the slide grooves 10. When the connecting plate 9 moves along the slot 3, the roller 8 can be clamped in the slide grooves 10 so that the connecting plate 9 will not fall out of the slot 3. Preferably, there are two mounting holes, which are symmetrically arranged along the longitudinal axis of the auxiliary support plate, and rollers are arranged in each mounting hole, which can make the movement more stable. At the same time, the outer ring of the roller 8 is made of rubber, which can reduce the noise during movement.
[0029] A positioning pin 5 is provided on the connecting plate 9. The top end and the bottom end of the positioning pin 5 respectively extend outside the top surface and the bottom surface of the connecting plate 9 and correspond to the positioning holes 6 and the relief groove 7, so that the top end of the positioning pin 5 can be inserted into the positioning holes 6 to prevent the connecting plate from moving and realize positioning. At the same time, the bottom end of the positioning pin 5 is placed in the relief groove 7 to facilitate its movement along the relief groove 7. Preferably, the positioning pin 5 is a spring pin, and a handle is provided at its bottom end for convenient pulling and resetting.
[0030] During use, grasp the handle of the positioning pin and pull it downwards to disengage the top end from the positioning hole. Then, move the auxiliary support plate along the slot to the desired position according to the patient's body type, which can not only meet the placement requirements of the patient's upper limb but also avoid affecting the operator. Finally, release the handle, allowing the positioning pin to move upwards under the action of elastic force, and at the same time move the auxiliary support plate appropriately to ensure that the positioning pin is inserted into the positioning hole, so that the main and auxiliary support plates form a proper upper limb support plate structure, fully meeting the surgical requirements and creating favorable conditions for the normal progress of the surgery.
[0031] The parts not involved in the present utility model are the same as or can be implemented using the prior art.
