[0002] Wounds are damage to normal skin (tissue) caused by external factors such as surgery, external force, heat, electric current, chemicals, low temperature, and internal factors such as local blood supply disorders. At present, wounds are repaired by suturing directly with needles and threads, but due to the natural tension of skin and muscles, suturing is difficult, deviations may occur, and even secondary injuries may occur, which is not conducive to the recovery of wounds.

[0003] To solve the above problems, Chinese patent with publication number CN214678954U discloses a traction device for wound repair in liposuction surgery, comprising a connecting frame and a traction seat, wherein the left and right ends of the connecting frame are provided with traction seats; the traction seat comprises a sliding rod, a base and a bottom plate, the sliding rod is fixedly connected to the outer side surfaces of the two ends of the connecting frame, the sliding rod is slidably connected to a connecting plate, the outer side surfaces of the two ends of the connecting frame are provided with a rotating seat, the rotating seat is rotatably connected to a screw rod, the left end of the screw rod is threadedly connected to the connecting plate, a plurality of screw holes are provided on the connecting plate, the screw and the sliding rod are connected through the screw holes and the connecting plate, an embedding groove is provided at the upper end of the base, the upper end of the base is slidably connected to the bottom plate through the embedding groove, a plurality of card slots are provided at the lower end of the base, a flange is provided on a side of the card slot away from the connecting frame, a plurality of card pins are provided at the upper end of the bottom plate, and the number of the card pins of the bottom plate and the card slots of the base are consistent and correspond one to one; the patent can pull the skin on both sides of the wound surface closer, which is beneficial to the suturing of the wound surface, that is, it is beneficial to the recovery of the wound surface.

[0004] The following problems exist during the actual use of the above patent: the traction seat achieves movement by rotating the screw, that is, the two traction seats need to be operated separately to achieve the close proximity of the two traction seats, which makes the operation cumbersome; and, if anesthesia is not given, one medical staff member operates the two traction seats separately, which will inevitably prolong the treatment time, that is, prolong the patient's pain duration. Summary of the invention

[0005] The present invention aims to provide a skin wound repair traction device to solve the problem of complicated operation of existing traction devices.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a skin wound repair traction device, comprising two traction seats, an adhesion layer is provided at the bottom of the traction seats, and an operating table, a bottom groove is provided at the bottom of the operating table, and bottom blocks are slidably connected to both sides of the bottom groove; a bidirectional screw is rotatably connected to the operating table, the bidirectional screw passes through the bottom groove, and the two bottom blocks are respectively threadedly connected to the two ends of the bidirectional screw; side grooves are provided on both sides of the operating table, side blocks are slidably connected in the side grooves, and the side blocks are fixed to the traction seats.

[0007] The principles and advantages of this solution are:

[0008] 1. In this solution, the bidirectional screw is rotated so that the two bottom blocks move laterally along the length direction of the bidirectional screw, so that the two bottom blocks are brought closer together, thereby driving the two traction seats closer together, that is, the skin on both sides of the wound surface is pulled closer to the middle through the two traction seats; when the two traction seats move to the appropriate position, the bidirectional screw is stopped from rotating, thereby achieving the stopping of the two bottom blocks, thereby achieving the stopping of the two traction seats, so that medical personnel can suture the wound surface; compared with the prior art, this solution can be operated more conveniently by adjusting the positions of the two traction seats.

[0009] 2. In this solution, when the two bases are close to each other, the two traction seats are also close to each other, so that the traction seats drive the side blocks to move in the side grooves, thereby guiding the traction seats; and the movement of the side blocks and the movement of the bottom blocks are dispersed at two positions of the traction seats, thereby improving the stability of the movement of the traction seats.

[0010] Furthermore, a chamber is provided inside the operating table, and slide grooves are provided on both sides of the chamber, and sliders are slidably connected in the slide grooves, and a movable block is provided between the two sliders, and a first wedge block is provided on the movable block, and a stop groove is provided on the side wall of the first wedge block; a second wedge block for being squeezed by the first wedge block is slidably connected to the operating table, and a first spring is provided between the second wedge block and the operating table; and a linkage mechanism is also included that drives the movable block to move as the distance between the two bottom blocks changes.

[0011] Through the above arrangement, when the two bottom blocks are close to each other, the linkage mechanism drives the movable block and the first wedge block to move in the direction of the second wedge block; the movable block continues to move, so that the first wedge block squeezes the second wedge block to move outward, and the first spring is stretched; the movable block continues to move, so that the second wedge block abuts against the side wall of the first wedge block; the movable block continues to move, and when the two bottom blocks stop, the movable block also stops. At this time, the second wedge block is opposite to the stopping groove, so that the second wedge block slides into the stopping groove under the action of the first spring, thereby achieving the stopping of the first wedge block, and then strengthening the stopping effect of the traction seat through the movable block, the push block and the bottom block.

[0012] Furthermore, the chamber is communicated with the bottom groove; the linkage mechanism includes inclined grooves on both sides of the bottom groove and transverse grooves on both sides of the side walls of the movable block, and the spacing between the two inclined grooves gradually increases from top to bottom; a push block is slidably connected in the inclined groove, and the push block is slidably connected to the transverse groove. The push block can move horizontally and vertically in the bottom groove and the chamber, and the push block is against the movable block; a guide groove is provided on the bottom block, and the push block is slidably connected to the guide groove.

[0013] Through the above arrangement, when the two bases are close to each other, the bases move laterally, and the bases drive the push block to move laterally along the path of the transverse groove. At the same time, the push block also moves along the path of the inclined groove, so that the push block also moves upward relative to the guide groove, and the push block squeezes the movable block to drive the first wedge block to move in the direction of the second wedge block.

[0014] Furthermore, a third wedge block is provided on both sides of the first wedge block; wall grooves are provided on both sides of the inner wall of the chamber, a wall block is slidably connected in the wall groove, a second spring is provided between the wall block and the wall groove, and a fourth wedge block for resisting the third wedge block is provided on the wall block; side grooves are provided on both sides of the side wall of the movable block, and the wall block can move relatively horizontally and vertically in the side grooves; the wall block is located on the movement trajectory of the push block.

[0015] Through the above arrangement, when the two bases are approaching each other, the bases move laterally, and the bases drive the push blocks to move laterally along the path of the transverse groove, so that the two push blocks also approach each other, the two push blocks squeeze the two wall blocks to approach each other, the two wall blocks drive the two third wedge blocks to approach each other, and the second spring is stretched; the two bottom blocks continue to approach each other, and when the two bottom blocks stop, the third wedge block and the fourth wedge block abut against each other, thereby clamping the first wedge block and preventing the first wedge block from moving in the opposite direction, thereby strengthening the stopping effect on the traction seat through the movable block, the push block and the bottom block.

[0016] Furthermore, an elastic block is provided on the side wall of the wall block, the elastic block is arc-shaped, and the convex part of the elastic block is arranged toward the movable block; strip grooves are provided on both sides of the first wedge block, and the end of the elastic block away from the wall block is slidably connected to the strip groove; limiting grooves are provided on both sides of the side wall of the movable block, and elastic layers are provided on both sides of the limiting grooves, the gap between the two elastic layers gradually decreases from top to bottom, and the convex part of the elastic block can extend into the gap between the two elastic layers.

[0017] Through the above arrangement, when the two bases are approaching, the movable block drives the first wedge block to move in the direction of the second wedge block, so that the wall block moves relatively horizontally and vertically in the side groove; as the two wall blocks are approaching, the distance between a single wall block and the first wedge block is reduced, thereby increasing the amplitude of the raised portion of the elastic block, that is, driving the elastic block to approach the movable block; at the same time, as the movable block drives the first wedge block to move in the direction of the second wedge block, the movable block also approaches the elastic block, and when the two bases are stopped, the raised portion of the elastic block extends into the gap between the two elastic layers; as the gap between the two elastic layers gradually decreases from top to bottom, the two elastic layers can limit the elastic block, and then limit the first wedge, and then strengthen the stopping effect of the traction seat through the movable block, the push block and the bottom block.

[0018] During the movement of the first wedge block toward the second wedge block, the end of the elastic block away from the wall block moves relatively in the strip groove.

[0019] Furthermore, both sides of the chamber are rotatably connected with a rotating shaft, and an elliptical block that can simultaneously resist the wall block and the inner wall of the chamber is coaxially connected to the rotating shaft, and also includes a power mechanism that drives the rotating shaft to rotate as the side blocks move.

[0020] Through the above arrangement, during the movement of the side block, the power mechanism drives the rotating shaft to rotate, and the rotating shaft drives the elliptical block to rotate; when the two bases stop, the side blocks also stop, and at this time, the two long axis ends of the elliptical block are against the wall block and the inner wall of the chamber, so as to achieve the tightening of the wall block, and then the third wedge block and the fourth wedge block are against each other to strengthen the stopping effect on the first wedge block, that is, the movable block, the push block, and the bottom block are used to strengthen the stopping effect on the traction seat.

[0021] Furthermore, the side groove is communicated with the chamber, and the power mechanism includes a gear coaxially connected to the rotating shaft and a rack fixed to the side block. The gear is located on the movement track of the rack, and the gear can mesh with the rack.

[0022] Through the above arrangement, during the movement of the side block, the side block drives the rack to move synchronously, so that the rack meshes with the gear to drive the rotating shaft to rotate, and the rotating shaft drives the elliptical block to rotate.

[0023] Furthermore, a handle is provided on the bidirectional screw.

[0024] Through the above arrangement, the bidirectional screw is driven to rotate by the handle, which makes the operation easier. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] An elastic block 50 is fixedly connected to the side wall of the wall block 42. The elastic block 50 is an elastic iron sheet and is arc-shaped. The raised portion of the elastic block 50 is arranged toward the movable block 23. Strip grooves 51 are provided on both sides of the first wedge block 24.

[0037] The specific implementation process is as follows:

[0038] When in use, the two traction seats 10 are placed on both sides of the wound surface and adhered to the patient's skin through the adhesive layer 11 .

[0039] The bidirectional screw 15 is driven to rotate by the handle 16, so that the two bottom blocks 14 move laterally along the length direction of the bidirectional screw 15, so that the two bottom blocks 14 are brought closer, and then the two traction seats 10 are driven closer, that is, the skin on both sides of the wound surface is pulled closer to the middle by the two traction seats 10; when the two traction seats 10 move to the appropriate position, the bidirectional screw 15 is stopped, so as to achieve the stopping of the two bottom blocks 14, and then the stopping of the two traction seats 10, so that medical personnel can suture the wound surface.

[0040] When the two bases are close to each other, the bases move laterally, and the bases drive the push block 32 to move laterally along the path of the transverse groove 31. At the same time, the push block 32 also moves along the path of the inclined groove 30, so that the push block 32 also moves upward relative to the guide groove 33, and the push block 32 squeezes the movable block 23 to drive the first wedge block 24 to move in the direction of the second wedge block 26; the movable block 23 continues to move, so that the first wedge block 24 squeezes the second wedge block 26 to move outward, and the first spring 27 is stretched; the movable block 23 continues to move, so that the second wedge block 26 abuts against the side wall of the first wedge block 24; the movable block 23 continues to move again, and when the two bottom blocks 14 stop, the movable block 23 also stops. At this time, the second wedge block 26 is opposite to the stop groove 25, so that the second wedge block 26 slides into the stop groove 25 under the action of the first spring 27, thereby achieving the stopping of the first wedge block 24, and then the stopping effect of the traction seat 10 is strengthened through the movable block 23, the push block 32, and the bottom block 14.

[0041] During the approach of the two bases, the bases move laterally, and the bases drive the push block 32 to move laterally along the path of the transverse groove 31, so that the two push blocks 32 also approach each other, and the two push blocks 32 squeeze the two wall blocks 42 to approach each other, and the two wall blocks 42 drive the two third wedge blocks 40 to approach each other, and the second spring 43 is stretched; the two bottom blocks 14 continue to approach each other, and when the two bottom blocks 14 stop, the third wedge block 40 and the fourth wedge block 44 abut against each other, so as to clamp the first wedge block 24 and prevent the first wedge block 24 from moving in the opposite direction, thereby strengthening the stopping effect of the traction seat 10 through the movable block 23, the push block 32 and the bottom block 14.

[0042] During the approach of the two bases, the movable block 23 drives the first wedge block 24 to move in the direction of the second wedge block 26, so that the wall block 42 moves relatively horizontally and vertically in the side groove 45; due to the approach of the two wall blocks 42, the distance between the single wall block 42 and the first wedge block 24 is reduced, thereby increasing the amplitude of the raised portion of the elastic block 50, that is, driving the elastic block 50 to approach the movable block 23; at the same time, since the movable block 23 drives the first wedge block 24 to move in the direction of the second wedge block 26, the movable block 23 also approaches the elastic block 50, and when the two bases are stopped, the raised portion of the elastic block 50 extends into the gap between the two elastic layers 53; since the gap between the two elastic layers 53 gradually decreases from top to bottom, the two elastic layers 53 can limit the elastic block 50, and then limit the first wedge block 24, and then strengthen the stopping effect of the traction seat 10 through the movable block 23, the push block 32, and the bottom block 14.

[0043] When the two bases are close to each other, the two traction seats 10 are also close to each other, so that the traction seat 10 drives the side block 18 to move in the side groove 17, so as to guide the traction seat 10 and further improve the stability of the movement of the traction seat 10; when the side block 18 moves, the side block 18 drives the rack 63 to move synchronously, so that the rack 63 is engaged with the gear 62 to drive the rotating shaft 60 to rotate, and the rotating shaft 60 drives the elliptical block 61 to rotate; when the two bases are stopped, the side block 18 is also stopped, and at this time, the two long axis ends of the elliptical block 61 are against the wall block 42 and the inner wall of the chamber 20, so as to achieve the tightness against the wall block 42, and then the third wedge block 40 and the fourth wedge block 44 are against each other to strengthen the stopping effect of the first wedge block 24, that is, the movable block 23, the push block 32, and the bottom block 14 are used to strengthen the stopping effect of the traction seat 10.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
