2. Stitching with stitching nails; the device similar to a stapler is adopted to staple the skin on two sides together, the time consumption of the stitching mode is slightly shorter than that of the traditional stitching mode, but the skin tension is still larger, the stitching nails clamp the skin, so that obvious centipede feet can be formed, and the scar is obvious after the wound is healed.
3. Intradermal suturing; the suture is buried in the dermis layer, so that the generation of centipede feet is avoided by avoiding the clamping and pressing of the epidermis, but the mode is longer in time consumption, the epidermis still has larger tension, and the wound folds, uneven heights, inconsistent heights of two sides and the like inevitably occur because the skin entering position, depth, needle spacing, knotting strength and the like of each needle cannot be guaranteed to be consistent, and the scar is still obvious after healing.
4. Zipper type adhesive bandage: directly tensioning the skin on both sides of the wound by the adhesive tape; the method has no centipede feet caused by the skin clamping and pressing, and relatively avoids the time consumption of intradermal suturing. However, this approach pulls only the epidermis layer skin, the deep dermis layer is free of faradays, more careful suturing of the dermis layer is often required, suturing of the epidermal tissue severely affects wound healing, time is still longer, and there is no effective epidermis lightening.
