Bidirectional external skin stretcher

Abstract

The invention discloses a 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 connecting strips; sutural holes fixed to the skin are formed in the fixing plates and the fixing sheets. The bidirectional external skin stretcher is convenient for stretching, high in stretchingefficiency and convenient to operate, and relieves the pain of a patient.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a 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 cooperating teeth and b...

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
