Description

Front guide type reverse-taking subcutaneous fat cutter

Technical Field

The invention relates to the technical field of medical instruments, in particular to a front guide type 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 prognosis of a patient with skin avulsion, after complete debridement, related medical experts and scholars propose to remove the torn skin subcutaneous adipose tissues, trim the skin into full thickness, uniformly punch holes on the surface of the skin to form a screen, implant the screen in the skin defect in situ, and obtain the blood supply of subcutaneous soft tissues by pressurizing, so that the survival rate of the torn 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 the complete separation of taking off the skin, 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. And the skin is flexible, so that the skin is easy to shrink and roll, the rolled skin is easy to cut when the drum-type dermatome cuts the subcutaneous fat of the torn skin, and the secondary damage to the skin is increased.
