[0044] The application will be further described in detail below in combination with the drawings and specific embodiments.

[0045] Reference Figures 1-12 The positioning device for upper limb surgery comprises a fixed plate 1, the front surface of the fixed plate 1 is provided with a lower concave part adapted to the palm, and the lower concave part comprises a finger lower concave part 2 corresponding to each finger and a palm center lower concave part 3 corresponding to the palm center. When the upper limb surgery is performed, the palm is placed on the front surface of the fixed plate 1, the fingers can be located in the finger lower concave parts 2, and the palm center can be located in the palm center lower concave part 3, so that the positioning effect of the hand is better. When used, the palm can be positioned in the lower concave part on both sides, that is, the palm center can face the lower concave part when used, or the back of the palm can face the lower concave part.

[0046] Of course, in order to fix the hand, the positioning device for upper limb surgery of the application further comprises a fixing member for fixing the hand. The simplest and most common fixing member is an elastic band, which can be used to fix the palm, or fix one finger or several fingers, or fix several fingers together, etc. Of course, the fixing member can also be a rope and the like.

[0047] At the same time, in order to position the fixing member, the fixed plate 1 is further provided with a positioning mechanism for positioning the fixing member. The simplest and most common positioning mechanism is a positioning hook 4, which can be used to tie or hang the fixing member such as an elastic band or a rope on the positioning hook 4. The best position of the positioning hook 4 is arranged on the side edge of the positioning plate 1, and the best is to arrange the positioning hook 4 on the side edge of the positioning plate 1, so as to facilitate the flexible arrangement of the fixing member such as an elastic band or a rope. Of course, the positioning mechanism can also adopt a positioning protrusion and the like, which is used to hang or tie the fixing member such as an elastic band or a rope. Of course, the positioning mechanism can also not be arranged, and the fixing member such as an elastic band or a rope can be directly hung or tied on the fixed plate.

[0048] In one embodiment, the palm center lower concave part 3 has a lower concave extension 5 extending to the side edge of the fixed plate, thereby forming a thumb position separate surgery functional area. Here, the so-called "thumb position separate surgery functional area" refers to that, due to the existence of the lower concave extension 5, when the thumb needs to be operated, the thumb can be individually pulled to the lower concave extension 5 to be individually fixed, so that the thumb can be individually operated.

[0049] In another embodiment, the separate operation of the thumb can be achieved by setting the thumb fixing plate 6, that is, the front of the fixing plate 1 is also provided with the vertical thumb fixing plate 6, which is located behind the finger lower recess 2. When the thumb needs to be operated separately, the thumb is pulled to the back of the thumb fixing plate 6, so that the thumb is fixed on the thumb fixing plate 6, and the thumb is fixed separately, which is beneficial to the operation of the thumb. In order to use different hand shapes, the thumb fixing plate 6 can also be adjusted in position on the front of the fixing plate 1, that is, the thumb fixing plate 6 can be moved and adjusted, so that it can adapt to different sizes and hand shapes. One of the ways to adjust the position is that the fixing plate 1 is provided with a row of adjustment grooves, and the thumb fixing plate 6 can be selectively inserted into the adjustment grooves. In Figure 3 、 Figure 4 、 Figure 5 The fixing plate described in the above includes the upper fixing plate 7 and the lower fixing plate 8, which are combined to form the fixing plate. The connection between the upper fixing plate 7 and the lower fixing plate 8 can be buckle connection, adhesion, welding and the like. At this time, the upper adjustment groove 9 can be provided on the upper fixing plate 7, and the lower adjustment groove 10 corresponding to the upper adjustment groove 9 can be provided on the lower fixing plate 8. The thumb fixing plate 6 is inserted into the upper adjustment groove 9 and the lower adjustment groove 10. It is best to provide the thumb fixing plate 6 on both sides of the front of the fixing plate 1. In this way, whether the palm surface faces the lower recess or the back of the palm faces the lower recess, the thumb can be fixed by the thumb fixing plate 6.

[0050] In an embodiment, the fixing plate 1 has a cavity. After the cavity is set, the cavity can be filled with a counterweight, so as to increase the weight of the fixing plate, and the stability of the fixing plate can be enhanced during operation. Another important role of setting the cavity is that a through hole 11 communicating with the cavity can be provided on the front of the fixing plate 1, and a drainage port 12 communicating with the cavity can also be provided on the side of the fixing plate 1. The through hole 11, the cavity and the drainage port 12 together form a waste liquid drainage system. The blood and water or flushing liquid generated during the operation can enter the cavity through the through hole 11, and then be drained out of the cavity through the drainage port 12, so as to avoid pollution of the operating table. Since the upper limb operation is often performed on the fingers, the through hole 11 is at least distributed on the finger lower recess 2.

[0051] In an embodiment, the fixing plate 1 includes the upper fixing plate 7 and the lower fixing plate 8, which are combined to form the cavity. This way of forming the cavity is simple and convenient. The lower recess is provided on the front of the upper fixing plate 7. At this time, the drainage port 12 is preferably provided on the lower fixing plate 8, which is beneficial to the drainage of waste liquid.

[0052] After the upper fixing plate 7 and the lower fixing plate 8 are set, a reinforcing rib 13 can be arranged on the inner surface of the upper fixing plate 7 to enhance the strength of the upper fixing plate 7. A support column 14 can also be arranged on the inner surface of the lower fixing plate 8, which abuts against the inner surface of the upper fixed top plate 4 after the upper fixing plate 7 and the lower fixing plate 8 are closed. Alternatively, a support column can be arranged on the inner surface of the upper fixing plate, which abuts against the inner surface of the lower fixed top plate after the upper fixing plate and the lower fixing plate are closed. After the support column 14 is arranged, the support column 14 supports the upper fixing plate 7 and the lower fixing plate 8, thereby further enhancing the strength of the fixing plates.

[0053] In one embodiment, the positioning device for upper limb surgery of the present application further comprises a support mechanism for supporting the fixing plate 1 when the fixing plate 1 is vertically placed, so that the fixing plate 1 can be vertically placed. That is, after the support mechanism is arranged, the fixing plate 1 can be placed horizontally or vertically by means of the support mechanism, thereby realizing multi-directional perspective functions, such as front, side and oblique perspective, which facilitates the postoperative adjustment of the surgeon.

[0054] The support mechanism can adopt various forms. In one embodiment, the support mechanism comprises a support leg 15 rotatably connected to the back of the fixing plate 1. When the fixing plate is placed horizontally, the support leg 15 is folded. When the fixing plate needs to be vertically placed, the support leg 15 is unfolded to support the fixing plate, thereby achieving the effect that the fixing plate 1 can be vertically placed. The vertical angle of the fixing plate 1 can be adjusted by adjusting the rotation angle of the support leg 15.

[0055] In order to further facilitate the adjustment of the vertical angle of the fixing plate, the support leg 15 comprises a plurality of sub-legs 16, which are movably connected to each other, thereby adjusting the length of the support leg 15 and further adjusting the vertical angle of the fixing plate 1. The movable connection between the sub-legs 16 is usually sliding connection, thereby achieving the telescopic effect of the support leg and the purpose of adjusting the length of the support leg. Of course, the movable connection between the sub-legs 16 can also be pivot connection or other forms. An embedding groove 24 can also be arranged on the back of the fixing plate 1, in which the support leg 15 is embedded when it is not unfolded, so that the back of the fixing plate 1 still maintains a relatively flat state.

[0056] In one embodiment, the support leg 15 comprises a first support leg and a second support leg. The first support leg is used to support the fixing plate 1 when the first side of the fixing plate 1 is vertically placed. The second support leg is used to support the fixing plate 1 when the second side of the fixing plate 1 is vertically placed. Figure 7 、 Figure 8In one embodiment, one of the support legs 15 is connected to the fixed plate 1 at a position close to one end of the fixed plate 1, and the other support leg 15 is connected to the fixed plate 1 at a position close to the other end of the fixed plate 1. The two support legs 15 are arranged obliquely relative to the fixed plate 1. When the support legs 15 are unfolded after being rotated, one of the support legs 15 can support one side of the fixed plate 1, and the other support leg 15 can support the other side of the fixed plate 1. Figure 9 In one embodiment, the two support legs 15 are arranged oppositely. One of the support legs 15 is connected to the fixed plate 1 at a position close to the middle of the fixed plate 1, and the other support leg 15 is connected to the fixed plate 1 at a position close to the middle of the fixed plate 1. When the support legs 15 are unfolded after being rotated, one of the support legs 15 can support one side of the fixed plate 1, and the other support leg 15 can support the other side of the fixed plate 1.

[0057] Of course, the aforementioned support mechanism can also adopt other structural forms, for example Figure 10-12 In one embodiment, the support seat 17 is connected to or supported on the side of the fixed plate 1, thereby supporting the fixed plate 1. The support seat 17 can also be directly connected to or supported on the fixed plate 1. Preferably, the support seat 17 is connected to the fixed plate 1. Figures 10-12 In one embodiment, the support seat 17 is provided with a positioning groove 18, and the fixed plate 1 is provided with a positioning rib 19. The positioning rib 19 is embedded in the positioning groove 18.

[0058] In one embodiment, the fixed plate 1 is further provided with a traction mechanism for retracting a surgical incision. During a blood vessel and nerve operation, the traction mechanism can retract the surgical incision, thereby fully exposing the incision and facilitating the operation of the doctor.

[0059] In one embodiment, the traction mechanism includes a belt 20 positioned on the fixed plate 1. The belt 20 is provided with a hook 21, which can retract the surgical incision. In order to facilitate the retraction of the surgical incision, the belt 20 is preferably an elastic belt, such as a silica gel belt.

[0060] In order to make the strap 20 with the hook 21 better adapt to the hand shape and different palm size, the strap 20 can be positioned on the fixing plate 1 in an adjustable manner, so as to adjust the effective length of the strap 20, i.e. the length between the strap 20 and the fixing plate 1 at the positioning position and the hook 21. In one embodiment, the side of the fixing plate 1 is provided with a hook 22, and the strap 20 is provided with a plurality of hanging holes 23, the hook 22 is selectively hung in the hanging hole 23, i.e. the effective length of the strap 20 can be adjusted, and when the positioning hook 4 is provided, the positioning hook 4 can be used as the hook 22. Of course, the fixing plate 1 can also be provided with a through hole, the strap 20 is passed through the through hole and then knotted to realize the positioning of the strap 20, and the length of the strap 20 passing through the through hole is adjusted to adjust the effective length of the strap 20; or the fixing plate 1 is provided with a protrusion, and the strap 20 is tied on the protrusion to realize the positioning of the strap 20, and different parts of the strap 20 are tied on the protrusion to adjust the effective length of the strap 20, etc.

[0061] Of course, the traction mechanism can also have other structural forms, for example, a longer hook connected to the fixing plate directly, etc.
