Skin extending and closing equipment

Abstract

The present invention discloses a set of equipment which comprises an extended and biologically compatible flexible support plate. The support plate comprises the following components: at least a series of holes which extend from a bottom part to a top part and are basically positioned adjacently with a first relative edge and a second relative edge of the support plate; a bent surface which extends from a surface of a base part of the support plate to the top part; a propulsion extension part which is basically positioned at a center line of the bent surface; and a releasable locking mechanism which is positioned along a vertical axis of the bent surface adjacently with the extension part. Therefore, the releasable fixing mechanism which positions first equipment and second equipment for contacting with the skin at the edge or adjacent part of opposite wounds and inserts the propulsion extension part of the first equipment into the second equipment facilitates skin extension, wound edge approaching, wound closing or combination thereof. The invention also discloses a method for promoting skin extension, wound edge approaching or wound closing in an object, and an external member which comprises wound closing equipment and at least one propulsion extension part.

Description

Background technique [0001] Many methods and devices are available for wound closure, including the use of sutures, staples, or adhesives. The main disadvantage of sutures is their small diameter and the resulting relatively high pressure on the tissue being treated (mainly the wound margin), which often leads to tearing of the tissue being sutured. Sutures that are tied and knotted too tightly can strangle tissue, leading to gangrene, dehiscence, and scarring. Skin staple application is also characterized by relatively high pressure on the wound edges. [0002] A major disadvantage of adhesive application is the potential for dehiscence, especially along wet wound edges, due to some dissolution of the adhesive by the wound fluid. The adhesive penetrates the cut edge and also creates a tattoo effect. Adhesives and tapes applied at or near the wound margins can absorb fluid from the wound, often loosen over time, and the porous fabric of the tape becomes a source of wound in...

AI Technical Summary

Problems solved by technology

However, the reason this device is problematic is that stretching and pulling can cause the skin or edges to tear and the device causes scarring, infection and reduced healing

[0004] Moreover, the wound closure devices described above have other limitations: they do not provide adequate closure for large wounds where a more gradual closure is necessary
