technical field

The utility model relates to the field of medical instruments, in particular to a skin flap fixing device.

Background technique

Simple mastectomy refers to partial or total mastectomy performed under the skin, and the breast tissue and fat tissue are peeled off and removed from the pectoralis major muscle. During the operation, medical staff use nerve hooks, towel forceps or tissue forceps to clamp the edge of the flap in sections, pull it up tightly, and separate the flap with a scalpel or electric knife.
