The attachment strip 160 is made of a soft material, and specifically, the attachment strip 160 is a soft tape in the present embodiment.

The method of using the skin wound closure device 100 provided in this embodiment is as follows:

respectively sticking and fixing a pair of adhesive sheets 110 on two sides of a wound to be closed, wherein the distance between the pair of adhesive sheets 110 before closing is 0.5cm-25cm, the distance after closing is 0.2cm-2.0cm, the specific distance is related to the length of the wound, when the length of the wound is 1cm-3cm, the distance between the pair of adhesive sheets 110 before closing the wound is 8mm, and the distance after closing the wound is 3 mm; when the wound length is 3cm to 5cm, the distance between the pair of adhesive sheets 110 before wound closure is 10mm and the distance after wound closure is 5 mm; when the wound length is 5cm to 10cm, the distance between the pair of adhesive sheets 110 before wound closure is 12mm and the distance after wound closure is 8 mm; when the wound length is 10cm to 20cm, the distance between the pair of adhesive sheets 110 before wound closure is 15mm and the distance after wound closure is 10 mm; when the wound length is 20cm or more, the distance between the pair of adhesive sheets 110 before wound closure is 20mm and the distance after wound closure is 12 mm. The pull portion 140 is pulled in the direction of the arrow in fig. 2 to bring the two adhesive sheets 110 close to each other, thereby closing the wound, wherein the distance between the pair of adhesive sheets 110 is 0.2cm to 2.0 cm. After the wound is closed, the operator locks the portion of the pull wire that is pulled by the pull portion 140 using the locking wire block 150.

During the wound healing process, the position of the pull wire 130 locked by the wire locking block 150 can be adjusted, thereby adjusting the tightness of the pull wire 130. Specifically, if the pulling-in wire 130 becomes loose, the operator only needs to wind more pulling-out portions of the pulling-in wire around the wire locking block 150; if the pull-in wire 130 is too tight, the operator is required to pay out the pull-out portion of the pull-in wire of an appropriate length from the wire locking block 150.

After the wound is healed, the pair of adhesive sheets 110 may be directly separated from the skin without removing the pull line 130.

As shown in fig. 10 to 11, the present embodiment provides a skin wound closer 300 including: a pair of adhesive sheets 310, a pair of through-wires 320, a pull wire 330, a pull portion 340, a locking wire block 350, and a pair of attachment strips 360.

The skin wound closure device 300 provided by the present embodiment can be used for treating human wounds, and can also be used for treating animal wounds. In this embodiment, the skin wound closer 300 is used to treat a human wound.

A pair of adhesive sheets 310 are respectively used for adhesive fixation on both sides of a wound of a patient, each adhesive sheet 310 having a thickness of 3mm and a length of 6cm in the extending direction of the wound. Each adhesive sheet 310 has a plurality of ventilation holes for facilitating ventilation of the skin of a patient, and particularly, in the present embodiment, the number of ventilation holes in each adhesive sheet 310 is 20 and is arranged in a2 × 10 matrix.

In other embodiments, the thickness of the adhesive sheet 310 may be designed to be 1mm to 4mm according to actual needs, and the length along the extending direction of the wound may be designed to be 1cm to 30cm according to actual needs.

Specifically, in the case of treating a wound having a length of less than 1cm using the skin wound closer 300, the adhesive sheet 310 having a length of 1cm should be selected; in the case of treating a wound having a length of 25cm to 30cm using the skin wound closer 300, an adhesive sheet 310 having a length of 30cm should be selected.

In other embodiments, the sides of the pair of adhesive sheets 310 adjacent to each other are provided with bending prevention pieces made of a hard material. The skin wound closer 200 having the anti-bending sheet is generally applied to a long straight wound to prevent the adhesive sheet from being deformed and twisted to affect the wound closing effect.

A pair of through-wires 320 are symmetrically fixed on the upper surfaces of the two adhesive sheets 310, respectively, each through-wire 320 having a plurality of through holes, specifically, in the present embodiment, each through-wire 220 has 10 through holes 321, and threading slits 322 corresponding to and communicating with the through holes 321 one by one.

The thread-through slits 322 are used to facilitate pulling the closure thread quickly into the through-hole 321, thereby quickly assembling the skin wound closure 300, thereby facilitating production.

The through-holes of the via bars 320 all have a through-direction perpendicular to the length direction of the adhesive sheet 310.

The bonding wires 330 are disposed to pass through all the through holes symmetrically with the center line of the pair of adhesive sheets 310 as a symmetry axis and alternately penetrate between the pair of adhesive sheets 310. In a specific use process, only one pulling line 330 may be used, or two or more pulling lines 330 may be used simultaneously, depending on the pulling manner. In the present embodiment, the number of the bonding wires 330 is 1. In this embodiment, the pull-on thread 330 is disposed evenly between the pair of adhesive sheets 310, but in the treatment of certain specific wounds (e.g., wounds that span the joint), the pull-on thread 330 may be disposed densely in the middle and sparsely on both sides. The preferred material for the pull wire 330 is PTFE or Parylene, with a diameter of 0.2mm to 1.0 mm. In this embodiment, the suture 330 material is PTFE with a diameter of 0.5 mm.

As shown in fig. 12, for convenience of description, the vias 321 on one of the via bars 320 are sequentially named as via E1-via E10, and the vias 321 on the other via bar 320 are sequentially named as via F1-via F10.

In the present embodiment, the number of the bonding wires 330 is 1. One bonding wire 330 is inserted between the pair of adhesive sheets 310 in such a manner as to sequentially pass through a through hole E1, a through hole F1, a through hole F2, a through hole E2, a through hole E3, a through hole F3, a through hole F4, a through hole E4, a through hole E5, a through hole F5, a through hole F6, a through hole E6, a through hole E7, a through hole F7, a through hole F8, a through hole E8, a through hole E9, a through hole F10, a through hole E10, a through hole F10, a through hole E10, a through hole E9, a through hole F9, a through hole F8, a through hole E8, a through hole E7, a through hole F7, a through hole F6, a through hole E6, a through hole E5, a through hole F5, a through hole F4, a through hole E4, a through hole E3, a through hole F3, a through hole F2, a through hole E2, and a through hole F1, and both ends of the bonding wire 330 are bonded to the bonding portion 340.

A pull 340 is provided for the operator to pull to bring the adhesive sheets 310 closer together to close the wound. Specifically, the pull portion 340 may be a pull ring disposed on the pull wire 330 or a portion of the pull wire 330 having an indicating function, such as indicating by dyeing or knotting. Specifically, in the present embodiment, the pull portion 340 is a pull ring, and both ends of the pull line 330 are bound to the pull portion 340.

The locking wire block 350 is fixed to the upper surface of the adhesive sheet 310 at a position corresponding to the pull portion 340, and a wire groove for passing the pull-out portion of the pull-up wire is formed with the adhesive sheet 310 to lock the pull-out portion of the pull-up wire to the locking block 350. The pull string withdrawing portion is a portion of the pull string withdrawn by the pull portion 340 when the pair of adhesive sheets 310 are brought close to each other to close the wound. The pull-out portion of the closure wire may be pre-locked to the wire locking block 350 or may be locked to the wire locking block 350 after the wound is closed. In this embodiment, the operator locks the pull-in wire pulling part using the wire locking block 350 after closing the wound.

The specific structure of the wire locking block 350 in this embodiment is identical to that of the wire locking block 150 in embodiment 1, and is not described herein again.

In other embodiments, the wire locking block 350 can be replaced with any one of a clip 370, a snap 380, and a turn 390.

The specific structures of the clip 370, the snap 380, and the turn button 390 are respectively identical to the clip 170, the snap 180, and the turn button 190 in embodiment 1, and are not described herein again.

A pair of attachment strips 360 are attached to both ends of the two adhesive sheets 310, respectively, for attaching the two adhesive sheets 310 to the skin in parallel with each other. The length and width of the attachment strip 360 are set according to actual needs. The attachment strip 360 is made of a soft material, and specifically, in the present embodiment, the attachment strip 360 is a soft tape.

The method of using the skin wound closure device 300 provided in this embodiment is as follows:

a pair of adhesive sheets 310 are respectively stuck and fixed on two sides of a wound to be closed, wherein the distance between the pair of adhesive sheets 310 before the wound is closed is 0.5cm-25cm, the distance after the wound is closed is 0.2cm-2.0cm, the specific distance is related to the length of the wound, when the length of the wound is 1cm-3cm, the distance between the pair of adhesive sheets 310 before the wound is closed is 8mm, and the distance after the wound is closed is 3 mm; when the wound length is 3cm to 5cm, the distance between the pair of adhesive sheets 310 before wound closure is 10mm and the distance after wound closure is 5 mm; when the wound length is 5cm to 10cm, the distance between the pair of adhesive sheets 310 before wound closure is 12mm and the distance after wound closure is 8 mm; when the wound length is 10cm to 20cm, the distance between the pair of adhesive sheets 310 before wound closure is 15mm and the distance after wound closure is 10 mm; when the wound length is 20cm or more, the distance between the pair of adhesive sheets 310 before wound closure is 20mm and the distance after wound closure is 12 mm. The pull 340 is pulled in the direction of the arrow in fig. 11 to bring the two adhesive sheets 310 close to each other and close the wound, wherein the distance between the pair of adhesive sheets 310 is 0.2cm to 2.0 cm. After the wound is closed, the operator locks the portion of the pull wire that is pulled by the pull portion 340 using the locking wire block 350.

During the wound healing process, the position of the suture line 330 locked by the suture locking block 350 can be adjusted, thereby adjusting the tightness of the suture line 330. Specifically, if the pulling-in wire 330 becomes loose, the operator only needs to wind more pulling-out portions of the pulling-in wire around the wire locking block 350; if the pull-in wire 330 is too tight, the operator is required to pay out the pull-out portion of the pull-in wire of the appropriate length from the wire locking block 350.

After the wound is healed, the pair of adhesive sheets 310 may be directly separated from the skin without removing the pull wire 330.
