Automatic skin traction and folding device

Abstract

The invention discloses an automatic skin traction and folding device which is characterized by comprising a hollow arc-shaped outer guide cylinder and two hollow arc-shaped skin traction cylinders, wherein the two hollow arc-shaped skin traction cylinders are respectively sleeved in openings at two ends of the outer guide cylinder in a manner of sliding along the arc-shaped inner wall of the outer guide cylinder; the sliding-out ends of the skin traction cylinders are closed blind ends and are provided with skin traction hooks, the outer guide cylinder is provided with a driving mechanism, and the driving mechanism pushes the skin traction cylinders located on the skin edges on the two sides of the wound to move oppositely so that the skin can be automatically and continuously pulled under certain tension till the skin edges are folded; the elastic traction force applied by the two traction hooks automatically and continuously pulls the skin under a certain tension until the skin edges are folded, so that the skin traction device can well adapt to the tension of the skin, promote the rapid healing of the wound skin, avoid the drawing injury of the skin edges caused by overlarge traction amount, obviously shorten the treatment time and reduce the treatment cost. And secondary injury caused by skin grafting is avoided, and pain caused by an operation is avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an automatic skin traction and fitting device. Background technique [0002] All kinds of acute and chronic wounds, skin defects, osteofascial compartment syndrome, incision, decompression and mouth opening reduction are often used in previous treatments: 1. Skin grafting is used, but the existing problems are: 1. If full-thickness skin grafting is used, the survival rate will be lower. 2. If a medium-thick skin flap is used for transplantation, the skin graft is not wear-resistant, and the skin area is damaged; 3. If the deep bone tendon and other tissues are exposed, the donor site of the flap transplantation will be severely damaged And the risk is huge, and the patient acceptance is low. 2. The wound is closed by pulling and suturing multiple times in stages, and the patient needs multiple operations, which increases the pain of the patient and increases the treatment cost. P...
