This study will compare the experimental group (debridement assisted by surgical microscope + VSD) and the control group (debridement under naked-eye observation + VSD) in terms of the rate of change in BWAT scores at one week postoperatively when the VSD is removed, daily wound negative-pressure drainage volume and pain scores within the first postoperative week, and results of two wound bacterial cultures. The study aims to scientifically evaluate the difference in efficacy between microscope-assisted debridement and naked-eye debridement, with the goal of providing a reference for the clinical debridement treatment of skin wounds.
