In other embodiments, the adhesive sheet 110 side which is approaching to the other is provided with anti-bending board which is made of hard material. The skin closing apparatus provided with anti-bending board is generally used to close long and straight wound, preventing adhesive sheets 110 from distortion which has bad effect on wound closure.

Each pair of threading cubes 120 are symmetrically mounted the upper surface of adhesive sheets 110. All threading cubes 120 mounted on the same adhesive sheet 110 are line up in a row along the wound. More particularly, in this embodiment, the number of threading cubes 120 mounted the same adhesive sheets 110 is 10, lined up in a row along the wound and the distance between the neighboring two threading cubes mounted on the same adhesive sheet is 5 mm.

Each of the threading cubes 120 is arc shape provided a threading hole 121 and a threading perforation 122 communicated with the threading hole 121.

The locking square 173 is positioned on the same adhesive sheet 110 as the shell 171 positioned. which is arranged on the same adhesive sheet as the shell. By engaging the locking square with the convex square, the pull string is locked.

A pair of sticking strips 160 is stuck to the two sides of the adhesive sheet 110 respectively so that the adhesive sheets 110 are mounted on skin in a parallel manner. The length and width of the sticking strips 160 are set according to actual demands. The sticking strips 160 are made of soft materials and more particularly, in this embodiment, the sticking strips 160 are soft strips.

The instruction of the embodiment of the skin wound closing apparatus 100 is shown as below:

Position the adhesive sheets 110 at two sides of the wound respectively, and the distance between the adhesive sheets 110 is 0.5 cm˜25 cm. After the wound is closed, the distance between the adhesive sheets 110 is 0.2 cm˜2.0 cm, and the distance depends on the length of the wound. When the length of wound is 1 cm˜3 cm, the distance before the wound is closed is 8 mm and after the wound is closed, the distance is 3 mm; when the length of wound is 3 cm˜5 cm, the distance before the wound is closed is 10 mm, and after the wound is closed, the distance is 5 mm; when the length of the wound is 5 cm˜10 cm, the distance before the wound is closed is 12 mm and after the wound is closed, the distance is 8 mm; when the length of the wound is over 20 cm, the distance before the wound is closed is 20 mm and after the wound is closed is 12 mm. Pull the pull components 140 in the direction of the arrow showed in FIG. 2 to drive the adhesive sheets 110 closer to each other to close the wound. At the moment, the distance between two adhesive sheets 110 is 0.2 cm˜2.0 cm. After the wound is closed, the operator locks the part of pull string of the pull component 140 with the elastic needle locker 150.

In the process of the wound healing, the operator can adjust the position of the pull string 130 locked by the elastic needle locker 150 to adjust the tightness of the pull string 130.
