When in use, as shown in fig. 2, the thumb is inserted into the annular ring 1, and the thumb presses the pressing end 21 of the skin cutter 2, so that one end of the cutter head 22 is extruded out of the through hole 11, and the thumb is used for driving the annular ring 1 to move at the incision position, so that a preset incision length can be cut on a patient by the cutter head 22.

In the present embodiment, when the dermatome 2 is not in use, one end of the cutter head 22 is completely hidden in the through hole 11 of the annular ring 1, so that the operator cannot be injured. The elastic piece can be a structure such as an arc spring, a steel wire and a spring, which can extrude the pressing end 21 into the annular ring 1, and the peeling knife 2 can be prevented from being separated from the through hole 11 through the cooperation of the through hole 11 and the elastic piece, such as a baffle ring, a stop block and the like which are arranged at the through hole 11 and used for preventing the pressing end 21 from being separated. At the same time, the thickness of the annular ring 1 also needs to be ensured to be able to completely conceal the cutter head 22.

The annular ring 1 is made elastically, so that the annular ring 1 can be tightly attached to the outer surfaces of thumbs of different users, and smooth skin cutting process is ensured. As shown in fig. 3, the annular ring 1 has a certain width to facilitate thumb force and manipulation. The new skin cutter 2 is used for each operation, so that repeated disinfection cost can be reduced, labor cost for disassembling and assembling the cutter is reduced, misoperation of medical staff is reduced, misoperation of skin injury of a patient is reduced, and quick operation of young doctors is facilitated.
