Technical Field

The invention relates to the technical field of medical instruments, in particular to a reverse subcutaneous fat cutter.

Background

In recent years, the incidence of traffic accidents is increasing, the incidence of patients with limb skin avulsion is on a trend of rising year by year, the skin at the avulsion part has no blood supply and no blood supply, if the injured skin of the patients can not be treated in time, severe skin necrosis can be caused, large-area skin soft tissue defects of limbs can be caused, and the treatment is very troublesome.

In order to improve the disease prognosis of patients with skin avulsion, related medical experts and scholars propose that after thorough debridement, the subcutaneous adipose tissues of the avulsed skin are removed, the skin is trimmed to be full-thickness, holes are uniformly punched on the surface of the skin to form a screen, the screen is transplanted to the defect part of the skin in situ, and the blood supply of subcutaneous soft tissues is obtained through pressurization, so that the survival rate of the avulsed skin is improved. However, at present, due to the lack of related auxiliary surgical tools, doctors can only clamp the conjoined torn skin by using surgical forceps, open and peel the skin, and then cut off the subcutaneous fat layer by layer on the torn skin by using surgical scissors. Although traditional drum-type dermatotome of getting can reject and tear skin subcutaneous fat, complex operation need tear and take off the skin separation, cuts into polylith skin and just can accomplish the operation, and the skin of separation lacks the blood supply moreover, and the degree of difficulty and the quality of survival all have very big influence.
