This utility model provides a surgical dressing change device to prevent cross-infection, relating to the technical field of surgical dressing change devices. It includes a dressing table with a disinfection mechanism at its front. The disinfection mechanism includes two first-step motors, each with its bottom surface fixedly connected to the outer surface of the dressing table. Two threaded shafts are rotatably connected to the inner wall of the dressing table, with the end of each threaded shaft near the first-step motor fixedly connected to its output end. A movable box is threadedly connected to the outer surfaces of the two threaded shafts, and a water pump is fixedly connected to the upper surface of the movable box.

This effectively avoids the problem of increased workload and longer disinfection cycles for medical staff caused by the lack of automatic disinfection functionality in traditional dressing change devices.
