Skin stretcher

Abstract

The present invention discloses a skin stretcher comprising a puller wire for connecting a wound skin, the puller wire has a plurality of wire ends, the skin stretcher is characterized in that the skin stretcher further comprises a tightener connecting all the wire ends and rotating to tighten the wire ends, and a gatherer for collecting all the wire ends. The skin stretcher of the invention uniformly pulls from a plurality of points to the center, gradually reduces the wound, and finally eliminates the wound surface. Compared with the traditional structure, the skin stretcher has more stresspoints and uniform force, which can effectively reduce the accidental occurrence of skin tearing at the force point and greatly reduce the second pain of the patient.

Description

technical field [0001] The invention belongs to the medical field, and in particular relates to a skin stretcher. Background technique [0002] Clinically, it is common for skin wounds to be closed and sutured directly due to excessive tension of the wound margins. In the past, it was necessary to use skin grafting or skin flap transfer for repair, but the trauma was large, the hospitalization time was long, and the medical expenses were high. In recent years, the skin external stretching technique has been introduced into the clinical treatment of such wounds that are difficult to suture directly. The principle is to take advantage of the looseness and extensibility of the skin, use an external stretcher to pull the skin edges on both sides of the wound toward the center, gradually shrink the wound, and finally suture to eliminate the wound. [0003] The currently used distractor is an independent pair of cooperating teeth and buckles, which are respectively sutured and f...

AI Technical Summary

Problems solved by technology

However, the obvious defect of such a distractor is that the stress point is limited to several points in the longitudinal direction of the edge of the wound, and the following disadvantages will occur during use: 1. low stretching efficiency and long treatment time; The skin at the point of force is torn, causing secondary injury and increasing the pain of the patient; 3. Because the skin at the wound edge often has adverse conditions such as inflammation, edema, and scar hyperplasia, the ductility is poor, and the skin texture becomes thinner after forced stretching, which affects wound healing Quality; 4. More and healthier skin on both sides of the wound is not effectively mobilized
