Skin incising and suturing device and application method thereof

The invention belongs to the field of medical apparatuses and instruments, specifically relates to a skin incising and suturing device and an application method thereof, and aims at solving the problems that the skin incising depth is difficultly accurately controlled in the existing operation, bleeding occurs once incising, and excessive electric coagulation hemostasis influences skin healing. The skin incising and suturing device comprises an incising and suturing unit, an incising guide positioning needle and an extruding sticking film; the incising and suturing unit comprises a rotating shaft, a sliding rod, a first connecting rod and a second connecting rod; a suturing needle round barrel which rotates about the rotating shaft is mounted on the rotating shaft; an arc-shaped suturing needle is connected to the suturing needle round barrel; a blade is mounted on the sliding rod. With the adoption of the skin incising and suturing device, the skin incising depth can be controlled, thus that breeding occurs as the skin is incised and the corresponding electric coagulation hemostasis can be minimized; the skin can be simply, quickly and accurately sutured after the operation; therefore, the skin incision healing quality can be effectively improved.
