Flexible skin distraction closer

Abstract

The invention provides a flexible skin distraction closer. The flexible skin distraction closer comprises a fixing assembly and at least one drawing assembly; the fixing assembly comprises a pair of fixing plates and adhesive tape attached to release paper; the pair of fixing plates is arranged on two sides of injured skin; ends of the adhesive tape are attached to the surfaces of the fixing plates; Each drawing assembly comprises a clamping groove, a buckle and a pull strip; the clamping groove is fixedly connected to one of the pair of fixing plates; the buckle is fixedly connected to the other one of the pair of fixing plates; the pull strip is provided with a tooth groove; the pull strip penetrates through the clamping groove and the buckle; and the pull strip is movably matched with the buckle. The flexible skin distraction closer is used for distracting wound skin which is difficult to directly suture, can be bent and well attached to the skin by adopting the flexible pull strips and flexible connecting strips, and is suitable for various regular or irregular, flat or uneven wounds.

Description

technical field [0001] The invention relates to the technical field of clinically applicable surgical instruments for trauma surgery, orthopedics and plastic surgery, in particular to a flexible skin stretch closure. Background technique [0002] Skin defect is a difficult problem that surgeons often need to deal with clinically. Common causes of skin defects include tumors, scars, trauma, inflammation, and skin lesions. Larger skin defects cannot be directly sutured to close the wound. At present, the main methods of clinical treatment of skin defects at home and abroad include skin grafting, skin flap transplantation, artificial skin, skin expansion, and skin stretching. The usual treatment is skin flap transplantation or skin expansion, which is complicated and has high complications. [0003] Skin stretching and stretching uses a skin stretching closure to make use of the stretchability of the skin to stretch the normal skin on both sides of the skin defect under exter...

AI Technical Summary

Problems solved by technology

The existing skin stretch closures that are currently clinical or still in the research and development stage have the following deficiencies: 1. The structure is too complicated, and the clinical installation operation is cumbersome and time-consuming, which increases the operating burden of medical staff; 2. The traction force is insufficient or excessive. Large, the stretching force cannot be effectively adjusted locally to suit the stretching force needs of different parts of the wound; 3. Most of the stretching is unidirectionally adjusted, and it cannot or is not easy to retreat when the stretch is too tight; 4. The cross-section is mostly flat The design cannot adapt to non-planar or irregular wounds; 5. It is large in size, and it is inconvenient for patients who cannot be stretched and closed on the operating table for a short time and need to wear it for a long time; 6. It is expensive. heavy financial burden on patients
