Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a skin wound stapler. Background Art

[0002] When treating skin wounds, traditional suture stitching will cause secondary damage to the skin and form suture scars. To reduce the use of sutures, currently on the market, a skin wound stapler is used to dock and fit the skin at the wound. The stapler consists of a locking seat and a locking strip that cooperate with each other and can be adjusted and positioned. The locking seat and the locking strip are respectively fixed on the left and right substrates. Each substrate is adhered to the skin on both sides of the wound through an adhesive layer. By pulling the locking strip, the skin on both sides of the wound is pulled closer and tightened to achieve natural healing of the skin.

[0003] Multiple staplers are arranged in a row at the wound. Since the locking strip of such a stapler is pulled unidirectionally, the skin on both sides of the stapler is unevenly stressed. When the staplers are pulled together in sequence, the skin between adjacent staplers is prone to shift, thus affecting the flatness of the wound and resulting in poor healing effect. Summary of the Utility Model

[0004] To solve the deficiencies of the above-mentioned prior art, the utility model provides a skin wound stapler, which realizes bilateral stretching, improves the stress effect of the skin on both sides of the wound, prevents skin shift, and further improves the flatness and healing effect of the wound.

[0005] The technical solution of the utility model is as follows: A skin wound stapler includes two identical stapling units. Each stapling unit includes a substrate and a locking seat fixed at the front end of the substrate. The bottom of the substrate is provided with an adhesive layer. A locking strip extending away from the substrate is fixed outside the locking seat. The locking strip is provided with a tooth groove along its length direction. A locking hole is provided on the locking seat on one side of the locking strip. A ratchet portion is provided on the locking seat on the side of the locking hole. The locking strip of one stapling unit is inserted into the locking hole of the other stapling unit, and the tooth groove of the locking strip meshes with the ratchet portion. By providing a locking seat with both a locking hole and a locking strip on the substrate, two identical stapling units are formed. The locking strip of one stapling unit is inserted into the locking hole of the other stapling unit. With the cooperation of the tooth groove and the ratchet portion, the locking of bilateral stretching is completed, so that the skin adhered by the two substrates is evenly stressed, thereby preventing skin shift and improving the flatness and healing effect of the wound.

[0006] A locking groove opening away from the locking strip is provided inside the locking seat, and the locking groove is communicated with the locking hole. A tongue is fixed in the locking groove, and the ratchet portion is formed on the side of the tongue facing the locking hole.

[0007] There is an active gap between the groove wall on the side of the locking groove facing away from the ratchet part of the tongue and the tongue, and a limiting part that slidably contacts the side of the locking bar facing away from the tooth groove is provided on the groove wall on the other side of the locking groove.

[0008] The locking bar and the elastic tongue of the same anastomosis unit are located on the same side of the locking hole, and the tooth groove of the locking bar is located on the side of the locking bar facing the locking hole.

[0009] The tooth grooves on the locking bars of different anastomosis units are meshed with each other. The tooth grooves on the locking bars of the two anastomosis units are arranged opposite to each other and meshed with each other to enhance the locking force between the two anastomosis units.

[0010] The locking bar and the elastic tongue of the same anastomosis unit are located on the opposite sides of the locking hole, and the tooth groove of the locking bar is located on the side of the locking bar facing away from the locking hole.

[0011] The sides of the locking bars of different anastomosis units that face away from the tooth grooves are in sliding contact.

[0012] Tail pieces are formed on both sides of the substrate. The tail pieces extend outward along the width direction of the substrate, and an adhesive layer identical to the bottom of the substrate is provided at the bottom of the tail pieces. The setting of the tail pieces increases the contact area between the substrate and the skin, and then increases the adhesion force at the bottom of the substrate.

[0013] A break is provided in the middle of the substrate. One end of the break extends below the locking seat and is communicated with the locking groove, and the other end of the break extends to the rear end of the substrate. The substrates on both sides of the break are fixedly connected by an easily bendable connecting strip. The break is provided in the middle of the substrate to increase the softness of the entire substrate. Furthermore, when pasting the substrate, the substrate can be bent according to the skin trend at the wound position to make it more conformable to the skin.

[0014] A number of ventilation holes are arranged in an array on the substrate and the tail pieces to increase the air permeability of the stapler.

[0015] The beneficial effects of the present utility model are as follows:

[0016] In this solution, by providing a locking seat with both a locking hole and a locking bar on the substrate, two anastomosis units with the same structure are formed. The locking bar of one anastomosis unit is inserted into the locking hole of the other anastomosis unit, and bilateral stretching locking is completed under the cooperation of the tooth groove and the ratchet part, so that the skin adhered by the two substrates is uniformly stressed, thereby preventing skin offset and improving the flatness and healing effect of the wound.

Detailed implementation manners

[0022] To enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings. Other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As shown in the accompanying drawings, the present invention provides a skin wound stapler, which includes two anastomosis units with the same structure. The anastomosis unit includes a substrate 1 and a locking seat 2 fixed to the front end of the substrate 1. A bonding layer is provided at the bottom of the substrate 1. A locking strip 3 extending away from the substrate 1 is fixed to the outside of the locking seat 2. A tooth groove 301 is formed along the length direction of the locking strip 3. A locking hole 202 is formed in the locking seat 2 on one side of the locking strip 3. A ratchet part 401 is provided on the locking seat 2 outside the locking hole 202. Preferably, in order to facilitate the one-time injection molding of the anastomosis unit, a locking groove 201 opening away from the locking strip 3 is formed inside the locking seat 2, and the locking groove 201 is communicated with the locking hole 202. A tongue 4 is fixed in the locking groove 201. The ratchet part 401 is formed on the side of the tongue 4 facing the locking hole 202. The locking strip 3 of one anastomosis unit is inserted into the locking hole 202 of another anastomosis unit, and the tooth groove 301 of the locking strip 3 meshes with the ratchet part 401 of the tongue. By providing a locking seat 2 with both a locking hole 202 and a locking strip 3 on the substrate 1, two anastomosis units with the same structure are formed. The locking strip 3 of one anastomosis unit is inserted into the locking hole 202 of another anastomosis unit. Under the cooperation of the tooth groove 301 and the ratchet part 401, bilateral stretching and locking are performed, so that the skin adhered by the two substrates 1 is stressed evenly, avoiding the deviation of the skin between adjacent staplers during pulling, and improving the flatness and healing effect of the wound.

[0024] There is a movable gap 203 between the groove wall on the side of the locking groove 201 facing away from the ratchet portion 401 of the tongue 4 and the tongue 4. At the same time, in order to ensure that the tongue 4 has a certain elasticity, the width of the connection between the tongue 4 and the locking groove 201 is smaller than the main body width of the tongue 4. There is a limiting portion 5 on the groove wall on the other side of the locking groove 201 that is in sliding contact with the side of the locking strip 3 facing away from the tooth groove 301. After the locking strip 3 passes through the locking hole 202, the side with the tooth groove 301 cooperates with the ratchet portion 401 of the tongue 4. Under the elastic action of the tongue 4, the other side of the locking strip 3 is attached to the limiting portion 5. At the same time, since the inclination direction of the tooth groove 301 of the locking strip 3 faces the side of the substrate 1 to which the locking strip 3 belongs, that is, the inclination direction of the tooth groove 301 is opposite to the pulling direction of the locking strip 3. When pulling the locking strip 3, the front tooth groove 301 drives the tongue 4 to move outwards and then rebound to cooperate with the rear tooth groove 301, thereby completing the tensioning operation of the locking strip 3.

[0025] As Figure 1 shown, in Embodiment 1, the locking strip 3 and the elastic tongue strip of the same anastomosis unit are located on the same side of the locking hole 202, and the tooth groove 301 of the locking strip 3 is located on the side of the locking strip 3 facing the locking hole; as Figure 2 shown, specifically, the tooth grooves 301 on the locking strips 3 of different anastomosis units are meshed, and the tooth grooves 301 on the locking strips 3 of the two anastomosis units are arranged oppositely and meshed with each other to enhance the locking force between the two anastomosis units.

[0026] As Figure 3 shown, in Embodiment 2, the locking strip 3 and the elastic tongue strip of the same anastomosis unit are located on the opposite sides of the locking hole 202, and the tooth groove 301 of the locking strip 3 is located on the side of the locking strip 3 facing away from the locking hole; as Figure 4 shown, the sides of the locking strips 3 of different anastomosis units facing away from the tooth grooves 301 are in sliding contact.

[0027] Further preferably, as Figure 1 shown, tail pieces 6 are formed on both sides of the substrate 1. The tail pieces 6 extend outwards along the width direction of the substrate 1, and an adhesive layer the same as the bottom of the substrate 1 is provided at the bottom of the tail pieces 6. In this embodiment, the number of tail pieces 6 is four, divided into two groups, with two in each group, which are respectively formed at both ends of the outside of the substrate 1 to increase the contact area between the substrate 1 and the skin, and then increase the adhesion at the bottom of the substrate 1 to prevent the substrate 1 from falling off.

[0028] In order to increase the softness of the entire substrate 1, and further, when pasting the substrate 1, the substrate 1 can be bent according to the skin direction at the wound position to make it more conformable to the skin. A break 101 is provided in the middle of the substrate 1. One end of the break 101 extends below the locking seat 2 and communicates with the locking groove 201. The other end of the break 101 extends to the rear end of the substrate 1. The substrate 1 on both sides of the break 101 is fixedly connected by an easily bendable connecting strip 7. In order to increase the air permeability of the stapler, a number of ventilation holes 102 are arranged in an array on the substrate 1 and the tail piece 6.

[0029] When implementing this technical solution, the substrates 1 of the two stapling units are pasted oppositely on the skin on both sides of the wound through the adhesive layer. According to the size of the wound, the appropriate number of staplers is selected and pasted in sequence. The locking strips 3 of each stapling unit are inserted into the locking holes 202 of the opposite stapling unit and pass out from the opening of the locking groove 201. At the same time, the two opposite locking strips 3 are pulled. Compared with the unilateral pulling force of the prior art, the skin on both sides can be evenly stressed. After the staplers are sequentially pulled together, the skin pulled together between adjacent staplers does not shift, ensuring the flatness of the wound and well promoting the wound healing.
