[0007] Preferably, the alignment mechanism also includes a gear fixedly connected to the outer wall of the nut, a fixed handle is rotatably connected to the outer wall of the nut, a handle is rotatably connected to the inner wall of the fixed handle, and a half gear is fixedly connected to the outer wall of the handle.

[0008] Preferably, the alignment mechanism also includes a large arc spring fixedly connected to the top of the handle, the top of the large arc spring is fixedly connected to the inner wall of the fixed handle, the top of the fixed handle is fixedly connected to a skin stapler, and the bottom of the hollow rectangular block is fixedly connected to a flattening assembly, and the fixed handle is moved to drive the hollow rectangular block to move to the front side on the slide rod through the nut and the screw rod, and then the handle is pinched to rotate the connection between the fixed handle and the handle, thereby driving the semi-gear to rotate, and the semi-gear drives the nut to rotate through the gear, so that the two screw rods are retracted and extended inward under the nut texture, thereby driving the two large medical double-sided adhesive stickers to pull the cracked part of the wound closer through the two fixed plates, so that the wound is aligned and the suturing efficiency is improved, and then the fixed handle is pressed down to move downward through the inner wall of the U-shaped bracket, thereby squeezing the spring plate to generate elastic force, driving the skin stapler to contact the wound, pressing the skin stapler to sew the wound, and driving the skin stapler to move backward on the slide rod through the fixed handle to sew different positions of the wound to prevent the skin wound from everting, thereby improving the suturing efficiency.

[0009] Preferably, the flattening assembly includes hollow fixing plates fixedly connected to the bottoms of the two hollow rectangular blocks, inner walls of the two hollow fixing plates are slidably connected with telescopic rods, and the bottoms of the two telescopic rods are fixedly connected with pressing plates.

[0010] Preferably, the flattening assembly also includes springs that are both sleeved on the outer wall of the telescopic rod, the bottoms of the two springs are fixedly connected to the pressing plate, the outer wall of the pressing plate is rotatably connected to a bracket, the outer wall of the bracket on one side away from the pressing plate is rotatably connected to a roller, a limiting assembly is fixedly connected to the hollow rectangular block, the fixed handle pulls the hollow rectangular block to move toward the middle through a screw rod, thereby driving the two hollow fixed plates to move on the two telescopic rods through the two hollow rectangular blocks respectively, when the hollow rectangular block moves downward, the pressing plate is driven to squeeze the wound through the hollow fixed plate, so that the spring generates elastic force, thereby reducing the degree of bulge of the wound, when squeezing downward, the bracket rotates upward with the pressing plate as the rotation point, driving the roller to rotate, flattening the bulge on the wound, and when the hollow rectangular block moves upward, it is reset under the action of the spring elastic force, preventing the skin of the wound from bulging when it is aligned, causing inflammation caused by the bulge of the wound after suturing, reducing the frequency of inflammation, and improving the efficiency of suturing.

[0011] Preferably, the limiting assembly includes an arc groove formed on the slide rod, the inner wall of the hollow rectangular block is fixedly connected to two fixing rods, and the outer walls of the two fixing rods are rotatably connected to clamping blocks.

[0012] Preferably, the limiting assembly also includes a small arc spring fixedly connected to the outer wall of the card block, the small arc spring is fixedly connected to the inner wall of the hollow rectangular block away from the card block, and the fixing plate is fixedly connected to an anti-wound cracking assembly. When the fixing handle drives the hollow rectangular block to move on the sliding rod through the screw rod, the card block in the hollow rectangular block is also moved through the fixing rod. Due to the sliding state of the card block and the arc groove, when the hollow rectangular block drives the card block to move, the edge of the arc groove will rotate with the fixing rod as a fulcrum, squeeze the small arc spring, and make the small arc spring generate elastic force, thereby passing the restriction of the arc groove. When the card block moves to the next arc groove, under the action of the elastic force of the small arc spring, the card block will be stuck in the arc groove, and the repeated movement can keep the positions equal each time when suturing, thereby improving the suturing effect.

When the two fixed plates move inward, the large hydraulic rod is squeezed by the two hollow fixed blocks, so that the liquid in the large hydraulic rod enters the small hydraulic rod through the pipe, and the small hydraulic rod is extended to drive the small medical double-sided adhesive sticker to move through the small fixed blocks, thereby performing secondary alignment on the wound. Because the large hydraulic rod and the small hydraulic rod are respectively slidably connected to the hollow fixed block and the fixed plate, when the positions of the two fixed plates deviate, the positions of the large hydraulic rod and the small hydraulic rod remain unchanged, so that when the wound is aligned, the position change is reduced, thereby improving the suturing efficiency.

[0015] A method for using a skin stapler for dermatological trauma comprises the following steps:

[0016] S1: Fixation device: fix two large medical double-sided adhesive tapes on both sides of the wound through two fixing plates;

[0017] S2: Adjust the position: Move and push the fixed handle to drive the hollow rectangular block to move to the front side on the slide bar through the nut and the screw rod;

[0018] S3: Starting device: pinch the handle to rotate the connection between the fixed handle and the handle, thereby driving the half gear to rotate, and the half gear drives the nut to rotate through the gear, so that the two screw rods are retracted inward under the nut texture, thereby driving the two large medical double-sided adhesive stickers through the two fixing plates to pull the cracked part of the wound closer, align the wound, and press the skin suture device to suture the wound.

[0019] The present invention has the following beneficial effects:

[0020] 1. When the present invention is aligning the wound, the skin at the wound is in an everted state, resulting in a poor alignment effect. Two large medical double-sided adhesive stickers are fixed to both sides of the wound through two fixing plates, and then the fixing handle is moved and pushed to drive the hollow rectangular block to move to the front side on the slide rod through the nut and the screw rod, and then the handle is pinched to rotate the connection between the fixing handle and the handle, thereby driving the semi-gear to rotate, and the semi-gear drives the nut to rotate through the gear, so that the two screw rods are retracted inwardly under the nut texture, thereby driving the two large medical double-sided adhesive stickers through the two fixing plates to pull the cracked part of the wound closer, so that the wound is aligned and the suturing efficiency is improved, and then the fixing handle is pressed down to move downward through the inner wall of the U-shaped bracket, thereby squeezing the spring plate to generate elastic force, driving the skin suturer to contact the wound, pressing the skin suturer to suture the wound, and driving the skin suturer to move backward on the slide rod through the fixing handle to suture different positions of the wound, preventing the skin wound from everting and improving the suturing efficiency.

[0021] 2. The present invention utilizes the force of the movement of the hollow rectangular block. The fixing handle pulls the hollow rectangular block toward the middle through the screw rod, thereby driving the two hollow fixed plates to move on the two telescopic rods respectively through the two hollow rectangular blocks. When the hollow rectangular block moves downward, the hollow fixed plate drives the pressure plate to squeeze the wound, so that the spring generates elastic force, thereby reducing the bulge of the wound. When squeezing downward, the bracket rotates upward with the pressure plate as the rotation point, driving the roller to rotate, flattening the bulge of the wound. When the hollow rectangular block moves upward, it is reset under the action of the spring elastic force, preventing the skin of the wound from bulging when it is aligned, resulting in inflammation caused by the bulge of the wound after suturing, reducing the frequency of inflammation, and improving the efficiency of suturing.

[0022] 3. The present invention utilizes the force of the hollow rectangular block moving on the slide rod. When the fixed handle drives the hollow rectangular block to move on the slide rod through the screw rod, the block in the hollow rectangular block is also moved through the fixed rod. Due to the sliding state of the block and the arc groove, when the hollow rectangular block drives the block to move, the edge of the arc groove rotates with the fixed rod as the fulcrum, squeezing the small arc spring to make the small arc spring generate elastic force, thereby passing through the restriction of the arc groove. When the block moves to the next arc groove, under the action of the elastic force of the small arc spring, the block will be stuck in the arc groove, and the movement is repeated in sequence. Since the positions between several arc grooves are equal, the positions can be kept equal each time when suturing, thereby improving the suturing effect.

[0023] 4. The present invention utilizes the force of the movement of two fixed plates. When the two fixed plates move inward, the large hydraulic rod is squeezed through the two hollow fixed blocks, so that the liquid in the large hydraulic rod enters the small hydraulic rod through the pipeline, and the small hydraulic rod is extended to drive the small medical double-sided adhesive tape to move through the small fixed block, thereby performing secondary alignment on the wound. Because the large hydraulic rod and the small hydraulic rod are respectively slidably connected to the hollow fixed block and the fixed plate, when the positions of the two fixed plates deviate, the positions of the large hydraulic rod and the small hydraulic rod remain unchanged, so that when the wound is aligned, the position change is reduced, thereby improving the suturing efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] For example, see Figure 1 - Figure 4 The present invention is a skin suture device for dermatological trauma, comprising two fixing plates 1, the bottoms of the two fixing plates 1 are fixedly connected with large medical double-sided adhesive tapes 11, and the two large medical double-sided adhesive tapes 11 are fixed on both sides of the wound through the two fixing plates 1;

[0038] An alignment mechanism 2, the alignment mechanism 2 comprises a screw rod 25, a U-shaped bracket 21, a slide rod 22, a spring plate 23, a hollow rectangular block 24 and a nut 26 for connecting the screw rod 25, and a flattening component 3 for flattening the protrusion of the wound;

[0039] Two U-shaped brackets 21 are fixedly connected to the top of the fixed plate 1, a sliding rod 22 is slidably connected between the two U-shaped brackets 21, a spring plate 23 is slidably connected to the notch of the U-shaped bracket 21, a hollow rectangular block 24 is slidably connected to the outer wall of the sliding rod 22, the hollow rectangular block 24 is slidably connected to the screw rod 25, and the screw rod 25 is threadedly connected to the nut 26.

[0040] The alignment mechanism 2 further comprises a gear 27 fixedly connected to the outer wall of the nut 26 , a fixing handle 28 is rotatably connected to the outer wall of the nut 26 , a handle 29 is rotatably connected to the inner wall of the fixing handle 28 , and a half gear 210 is fixedly connected to the outer wall of the handle 29 .

[0041] The alignment mechanism 2 also includes a large arc spring 211 fixedly connected to the top of the handle 29, the top of the large arc spring 211 is fixedly connected to the inner wall of the fixed handle 28, the top of the fixed handle 28 is fixedly connected to the skin suture 212, and the bottom of the hollow rectangular block 24 is fixedly connected to the flattening component 3. The fixed handle 28 is moved to drive the hollow rectangular block 24 to move to the front side on the slide bar 22 through the nut 26 and the screw rod 25, and then the handle 29 is pinched to rotate the connection between the fixed handle 28 and the handle 29, thereby driving the half gear 210 to rotate, and the half gear 210 drives the nut 26 to rotate through the gear 27, so that the two screws are The rod 25 expands and contracts inwardly under the texture of the nut 26, thereby driving the two large medical double-sided adhesive tapes 11 through the two fixing plates 1 to pull the cracked part of the wound closer, align the wound, and improve the suturing efficiency. Then, the fixing handle 28 is pressed down to move downward through the inner wall of the U-shaped bracket 21, thereby squeezing the spring plate 23 to generate elastic force, driving the skin stapler 212 to contact the wound, and pressing the skin stapler 212 to sew the wound. The skin stapler 212 is driven by the fixing handle 28 to move backward on the sliding rod 22 to sew different positions of the wound, thereby preventing the skin wound from everting and improving the suturing efficiency.

[0042] For example 2, please refer to Figure 5 - Fig. 9 The present invention is a skin suture device for dermatological trauma. Based on Example 1, the flattening component 3 includes hollow fixed plates 31 fixedly connected to the bottom of two hollow rectangular blocks 24, the inner walls of the two hollow fixed plates 31 are slidably connected with telescopic rods 32, and the bottoms of the two telescopic rods 32 are fixedly connected with pressing plates 33.

[0043] The flattening assembly 3 also includes springs 34 that are sleeved on the outer wall of the telescopic rod 32. The bottoms of the two springs 34 are fixedly connected to the pressure plate 33. The outer wall of the pressure plate 33 is rotatably connected to a bracket 35. The outer wall of the bracket 35 away from the pressure plate 33 is rotatably connected to a roller 36. The limit assembly 4 is fixedly connected to the hollow rectangular block 24. The fixing handle 28 pulls the hollow rectangular block 24 to move toward the middle through the screw rod 25, thereby driving the two hollow fixed plates 31 to move on the two telescopic rods 32 respectively through the two hollow rectangular blocks 24. When the rectangular block 24 moves downward, the hollow fixed plate 31 drives the pressure plate 33 to squeeze the wound, so that the spring 34 generates elastic force, thereby reducing the bulge of the wound. When squeezing downward, the bracket 35 rotates upward with the pressure plate 33 as the rotation point, driving the roller 36 to rotate, flattening the bulge of the wound. When the hollow rectangular block 24 moves upward, it is reset under the action of the elastic force of the spring 34, preventing the skin from bulging when the wound is aligned, causing inflammation caused by the bulge of the wound after suturing, reducing the frequency of inflammation, and improving the efficiency of suturing.

[0044] The limiting assembly 4 includes an arc groove 41 formed on the slide rod 22 . Two fixing rods 42 are fixedly connected to the inner wall of the hollow rectangular block 24 . The outer walls of the two fixing rods 42 are rotatably connected to clamping blocks 43 .

[0045] The limiting component 4 also includes a small arc spring 44 fixedly connected to the outer wall of the card block 43, and the small arc spring 44 is fixedly connected to the inner wall of the hollow rectangular block 24 on the side away from the card block 43. The anti-wound cracking component 5 is fixedly connected to the fixed plate 1. When the fixed handle 28 drives the hollow rectangular block 24 to move on the slide rod 22 through the screw rod 25, the card block 43 in the hollow rectangular block 24 is also moved through the fixed rod 42. Due to the sliding state of the card block 43 and the arc groove 41, the hollow rectangular block 24 drives the card block 4 When moving, the edge of the arc groove 41 rotates the clamping block 43 with the fixed rod 42 as the fulcrum, and squeezes the small arc spring 44, so that the small arc spring 44 generates elastic force, thereby passing through the restriction of the arc groove 41. When the clamping block 43 moves to the next arc groove 41, under the action of the elastic force of the small arc spring 44, the clamping block 43 will be clamped into the arc groove 41, and the movement is repeated in sequence. Since the positions of several arc grooves 41 are equal, the positions can be kept equal each time when suturing, thereby improving the suturing effect.

[0046] The wound cracking prevention component 5 also includes hollow fixed blocks 51 respectively fixedly connected to the tops of the two fixed plates 1, a large hydraulic rod 52 is slidably connected between the inner walls of the two hollow fixed blocks 51, a sliding groove 53 is provided on the side where the two fixed plates 1 are close to each other, and a small hydraulic rod 54 is slidably connected to the inner walls of the two sliding grooves 53.

[0047] The wound cracking prevention component 5 also includes pipes 55 that are both connected to the small hydraulic rods 54. The two pipes 55 are connected to the large hydraulic rod 52 at one side away from the two small hydraulic rods 54. The two small hydraulic rods 54 are fixedly connected to a small fixed block 56 on one side close to each other. The bottoms of the two small fixed blocks 56 are fixedly connected to a small medical double-sided adhesive tape 57. When the two fixing plates 1 move inward, the large hydraulic rod 52 is squeezed by the two hollow fixed blocks 51, so that the liquid in the large hydraulic rod 52 enters the small hydraulic rod 54 through the pipe 55, so that the small hydraulic rod 54 is extended and drives the small medical double-sided adhesive tape 57 to move through the small fixed block 56, thereby performing secondary alignment on the wound. Because the large hydraulic rod 52 and the small hydraulic rod 54 are respectively slidably connected to the hollow fixed block 51 and the fixing plate 1, when the positions of the two fixing plates 1 deviate, the positions of the large hydraulic rod 52 and the small hydraulic rod 54 remain unchanged, so that when the wound is aligned, the position change is reduced, thereby improving the suturing efficiency.

[0048] The method for using the skin stapler for dermatological trauma includes the following steps:

[0049] S1: Fixing device: fix two large medical double-sided adhesive tapes 11 on both sides of the wound through two fixing plates 1;

[0050] S2: Adjusting the position: moving and pushing the fixing handle 28 to drive the hollow rectangular block 24 to move to the front side on the slide bar 22 through the nut 26 and the screw rod 25;

[0051] S3: Starting device: pinch the handle 29 to rotate the connection between the fixing handle 28 and the handle 29, thereby driving the half gear 210 to rotate, and the half gear 210 drives the nut 26 to rotate through the gear 27, so that the two screw rods 25 are retracted inward under the texture of the nut 26, thereby driving the two large medical double-sided adhesive tapes 11 through the two fixing plates 1 to pull the cracked part of the wound closer, align the wound, and press the skin suture device 212 to suture the wound.

[0052] A specific application of this embodiment is: when in use, two large medical double-sided adhesive tapes 11 are fixed to both sides of the wound through two fixing plates 1, and then the fixing handle 28 is moved and pushed to drive the hollow rectangular block 24 to move to the front side on the slide bar 22 through the nut 26 and the screw rod 25, and then the handle 29 is pinched to rotate the connection between the fixing handle 28 and the handle 29, thereby driving the half gear 210 to rotate, and the half gear 210 drives the nut 26 to rotate through the gear 27, so that the two screw rods 25 are retracted inwardly under the texture of the nut 26, thereby The plate 1 drives two large medical double-sided adhesive tapes 11 to pull the cracked part of the wound closer together, align the wound and improve the suturing efficiency. Then, the fixing handle 28 is pressed down to move downward through the inner wall of the U-shaped bracket 21, thereby squeezing the spring plate 23 to generate elastic force, driving the skin suturer 212 to contact the wound, and pressing the skin suturer 212 to suture the wound. The skin suturer 212 is driven by the fixing handle 28 to move backward on the slide rod 22 to suture different positions of the wound, thereby preventing the skin wound from everting and improving the suturing efficiency.

[0053] When the skin is aligned, the wound may bulge, causing inflammation of the wound and increasing the time for subsequent treatment. The fixing handle 28 pulls the hollow rectangular block 24 to move toward the middle through the screw rod 25, thereby driving the two hollow fixing plates 31 to move on the two telescopic rods 32 through the two hollow rectangular blocks 24 respectively. When the hollow rectangular block 24 moves downward, the hollow fixing plate 31 drives the pressing plate 33 to squeeze the wound, so that the spring 34 generates elastic force, thereby reducing the bulge of the wound. When squeezing downward, the bracket 35 rotates upward with the pressing plate 33 as the rotation point, driving the roller 36 to rotate, and flattens the bulge of the wound. When the hollow rectangular block 24 moves upward, it is reset under the action of the elastic force of the spring 34, preventing the skin of the wound from bulging during alignment, causing the bulge of the wound after suturing to cause inflammation, reducing the frequency of inflammation, and improving the efficiency of suturing.

[0054] When suturing the skin, the suture position may remain inconsistent, resulting in a reduced suturing effect. When the fixing handle 28 drives the hollow rectangular block 24 to move on the slide rod 22 through the screw rod 25, the block 43 in the hollow rectangular block 24 is also moved through the fixing rod 42. Due to the sliding state of the block 43 and the arc groove 41, when the hollow rectangular block 24 drives the block 43 to move, the edge of the arc groove 41 rotates the block 43 with the fixing rod 42 as the fulcrum, and the small arc spring 44 is squeezed to make the small arc spring 44 generate elastic force, thereby passing through the restriction of the arc groove 41. When the block 43 moves to the next arc groove 41, under the action of the elastic force of the small arc spring 44, the block 43 will be stuck in the arc groove 41, and the movement is repeated in sequence. Because the positions between several arc grooves 41 are equal, the positions can be kept equal each time when suturing, thereby improving the suturing effect.

[0055] When the fixing handle 28 moves, fluctuations may occur when aligning the wound, resulting in position deviation during suturing. When the two fixing plates 1 move inward, the large hydraulic rod 52 is squeezed through the two hollow fixing blocks 51, so that the liquid in the large hydraulic rod 52 enters the small hydraulic rod 54 through the pipeline 55, and the small hydraulic rod 54 is extended to drive the small medical double-sided adhesive tape 57 to move through the small fixing block 56, thereby performing secondary alignment on the wound. Because the large hydraulic rod 52 and the small hydraulic rod 54 are respectively slidably connected to the hollow fixing block 51 and the fixing plate 1, when the positions of the two fixing plates 1 deviate, the positions of the large hydraulic rod 52 and the small hydraulic rod 54 remain unchanged, so that when the wound is aligned, the position change is reduced, thereby improving the suturing efficiency.
