Fastened-type bidirectional external skin stretcher

Abstract

The invention discloses a fastened-type bidirectional external skin stretcher which comprises two fixing plates fixed on the two sides of a wound of a human body, wherein a plurality of fixing sheets are correspondingly arranged on the opposite sides of the fixing plates; the fixing sheets on the two sides correspond in position, are same in number, all face to the wound and are detachably connected through traction fixing pieces; sutural holes fixed to the skin are formed in the fixing plates and the fixing sheets. The fastened-type bidirectional external skin stretcher is convenient for stretching and good in fixity, and cannot cause secondary injury to a patient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a snap-fit ​​bidirectional skin external 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 racks and bu...

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 can be produced during use: 1. It is easy to cause the skin at the stress point to tear, resulting in secondary injury, Increased patient suffering; 2. More and healthier skin on both sides of the wound is not effectively mobilized

3. The fixation is not good, and it is often necessary to use auxiliary devices such as wire ropes to tighten the fixation

4. The end of the rack used for pulling is exposed and is easy to be touched, causing re-injury to the patient
