Description

Step-by-step reverse removal subcutaneous fat remover

technical field

The invention relates to the technical field of medical devices, in particular to a step-by-step reverse extraction subcutaneous fat remover.

Background technique

In recent years, the incidence of traffic accidents has continued to increase, and the incidence of patients with skin avulsion injuries on the limbs has shown an upward trend year by year. The treatment of the damaged skin will cause severe skin necrosis, resulting in a large area of skin and soft tissue defects of the limbs, and the treatment is quite difficult.

In order to improve the prognosis of patients with skin avulsion, relevant medical experts and scholars proposed that after thorough debridement, the subcutaneous adipose tissue of the avulsed skin should be removed, trimmed into a full-thickness skin, and the surface of the skin should be uniformly perforated to form a screen mesh, and then replanted in the skin in situ. At the defect, the blood supply of the subcutaneous soft tissue is obtained by pressing, thereby improving the survival rate of the avulsed skin. However, due to the lack of relevant auxiliary surgical tools, doctors can only clamp the conjoined avulsion skin with surgical forceps, open and peel the skin, and then use surgical scissors to cut the subcutaneous fat on the avulsion skin layer by layer. Cutting, this operation is not only time-consuming, laborious and cumbersome, but also the thickness of the skin to be cut is difficult to control, and it is easy to cause secondary damage to the skin during cutting. Although the traditional drum dermatome can remove the subcutaneous fat from the avulsion skin, the operation is cumbersome. Quality has a big impact.
