Description

A Semi-Invasive Wound Stretch Closer

technical field

The invention relates to a semi-invasive wound distraction closure, which belongs to the field of surgical medical instruments.

Background technique

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. The principle of stretching the skin to promote the primary closure of wounds has been widely used to treat various skin injuries to assist wound healing and reduce the formation of scars. Most of the existing skin traction devices have a complex structure, which leads to the problem of complicated operation. In order to simplify the operation, many skin traction devices adopt a non-invasive design.

For example, the Chinese patent with the publication number CN112535536A discloses "an intelligently regulated skin stretch closure". unit, and another pulling unit composed of the central pulling module B arranged on the connecting plate and the pulling modules on both sides. The two pulling units are connected by T-shaped pull rods to form an "H" type skin stretching closure. Real-time monitoring of the pulling force is achieved, and the pulling force is precisely controlled at a stable and safe level. However, this solution is connected by screws and cannot be bent to adapt to large-area wounds.

Another Chinese patent with a publication number of CN113812994A discloses a "flexible skin stretch closure". This technical device is fixed on both sides of the wound by setting two fixing plates, and then adjusts and connects the two fixing plates through pull bars to achieve stretching. The role of skin wounds. Although this solution connects the fixed plate through flexible braces to achieve bending, it needs to fix two fixed plates during the operation, and then needs to adjust the position of the braces back and forth to achieve the best stretching position.
