The skin donor areas at different positions are selected according to the position and size of the wound surface, and are usually selected at the parts with loose and more concealed skin, such as groin, inner side of upper arm, lower part of clavicle or wrist palm side.
The processing method of the skin piece comprises the following steps: after the skin is taken down, the deep surface of the scissors is flattened, redundant skin is cut off, the skin area can be directly sutured, if the skin is taken as a thick-layer skin, part of dermis left on the wound surface is cut off, and then the wound surface is sutured;
the skin sheet is transplanted to cover the wound surface, the edge is sewed and long lines are left for wrapping;
covering the leather sheet with oil gauze, stacking mesh gauze, uniformly pressing the leather sheet, and tying and fixing with the remained long thread to make the leather sheet closely contact with the pressed area, thereby facilitating the healing of the leather sheet.
In prior art, generally remove the skin piece using tweezers, but current tweezers, when removing the skin piece, need push down the skin piece earlier then for the skin piece clamping-force, the skin piece that is in between two tweezers handles just can be held by tweezers to the middle uplift, but the operation can cause the skin piece unevenness like this, when some skin piece tissues of current tweezers centre gripping simultaneously, because dynamics control is not accurate, the clamping part of tweezers can cause the skin piece tissue to break, be unfavorable for the skin piece healing, influence later stage skin pleasing to the eye.
In a surgical operation of a hospital, for example, in the surgical operation of the hospital, for the excision of a tumor, a blood vessel forceps is generally adopted for lifting, so as to achieve the purpose of taking out the tumor in the surgical treatment, and the defects are as follows: when the vessel forceps are used for clamping, when the clamping jaws are opened, the occupied space is large, the clamping jaws easily cause tissue damage, meanwhile, the tumor body is easily broken due to extrusion, the transfer chance of malignant tumors is increased, and unnecessary pain and heavy economic burden are brought to patients.
