Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a cofferdam formula cutting ring suitable for edema surface of a wound.
Background
Macrophages, neutrophils and the like on the deep burn wound surface generate a large amount of NO, so that blood vessels on the wound surface are excessively expanded, and liquid in the blood vessels seeps out to tissue gaps to form edema. The edema of the wound surface causes blood concentration and local tissue pressure increase, thus causing blood circulation stasis of local tissues and blood circulation reduction of tissues in the congestion zone, thus aggravating ischemia and anoxia of tissues and progressively deepening the burn wound surface. When skin transplantation is carried out on edema and burn wounds, swelling needs to be relieved firstly, but the edema wounds can deepen the burn wounds. Therefore, early skin grafting on the edema wound surface is helpful for recovery of the burn wound surface, but when the edema wound surface is perforated for skin grafting, exudates of the edema wound surface flow into the holes, infection of the perforated parts is caused, the efficiency and quality of skin perforation are influenced, and the treatment effect of skin grafting is influenced. Therefore, the cofferdam type ring cutter suitable for the edema wound is designed, and the problem of skin transplantation of the early edema wound is solved.
