Flexible skin traction system

Abstract

The invention relates to a flexible skin traction system. The system is applied to a wound on the surface of the limb, and is characterized by comprising at least three anchor devices fixed on the surface layer of the skin; any two adjacent anchor devices are connected in a way that one end of a traction line is wound and fixed on a winding post of the first anchor device, the other end of the traction line is fixedly connected with an elastic piece, the elastic piece is sleeved in a sleeve, the sleeve is arranged in the surface layer of the skin at the edge of the wound in a penetrating mode,the other end of the elastic piece is fixedly connected with one end of the other traction line, and the other end of the other traction line is wound and fixed on a winding post of the second anchordevice; scales are arranged at the positions where the traction lines on the anchor devices pass through, and marks are arranged on the traction lines, so that the marks are located at the scale 0 positions when the lengths of the elastic pieces are just the original lengths; and the tension of each elastic piece is changed by adjusting the winding condition of each section of traction line on the corresponding winding post, so that the traction force of each edge of the wound is adjusted. According to the scheme, firstly the outline of the human limb can be fitted, the muscle or epidermis cannot be pressed and cut, in addition, different traction force can be generated at different positions, and the traction force is very convenient to adjust and read in the whole course of disease.

Description

Technical field[0001]This application relates to surgical medical instruments and trauma rehabilitation equipment, and in particular to a flexible skin pulling system.Background technique[0002]In the rehabilitation treatment of severe trauma, the skin is removed due to tearing or necrosis. After the subcutaneous injury is treated, it is necessary to slowly and continuously pull the edge of the skin at the incision to gradually proliferate to cover the wound again. The purpose of restoring skin function. The growth of the skin is relatively slow, so the stretching process takes several weeks to several months. During the pulling process, the size and direction of the pulling force must meet the requirements of the treatment and the specific conditions of the patient, otherwise it may cause uneven skin growth (excessive tension) or failure of the tension (excessive tension) ).[0003]In the prior art, such as CN104826219A, the principle is to pierce the puncture needle 34 into the skin ...

Problems solved by technology

[0005] However, the pulling force of this type of retractor is generated by a steel wire device, and the outline of the human body is not flat, but has radians everywhere. The steel wire with pulling force compresses and cuts the skin and flesh tissue, causing the tissue to break, which still has some shortcomings.
