Bandaging and fixing device after skin-grafting surgery

Abstract

The invention relates to a bandaging and fixing device after a skin-grafting surgery, and belongs to the technical field of medical apparatuses. The bandaging and fixing device is composed of an adsorption loop, a pressing cover and an air bag, the air bag is arranged on the bottom of the pressing cover, a pressing plate is movably arranged between the air bag and the pressing cover, and the adsorption ring is arranged on the periphery of the lower surface of the pressing plate arranged on the periphery of the air bag. The bandaging and fixing device can adjust bandaging pressure by controlling inflating volume of the air bag, balance pressure suffered by the grafted skin, so that the grafted skin can tightly fit skin tissue defect wound surfaces, and effusion can be absorbed by the adsorption loop arranged on the pressing cover, so that it is beneficial to subside tissue edema and promote granulation tissues neogenesis in the wound surfaces; survival rate of the grafted skin is further improved; the problem is solved that existing uneven pressure causes avascular necrosis of the grafted skin, and the bandaging and fixing device after the skin-grafting surgery has the advantages ofsimple structure and good practicability, and is particularly applicable to bandaging and fixing use after the skin-grafting surgery.

Problems solved by technology

[0002] Skin grafting is one of the most common operations in burn and plastic surgery; good bandaging and fixation is one of the most critical techniques to ensure the survival of skin grafting. After existing skin grafting operations, it is necessary to apply a certain amount of pressure to the grafted skin for bandaging to make the grafted skin close to the skin. Wounds with skin tissue defects, so that it does not cause ischemic necrosis or cannot establish a good blood supply; the existing bandage fixation method after skin grafting is to cover the grafted skin with sutures and reserve a certain length of sutures at the same time. Place a gauze bag on the surface of the grafted skin, and then fix the gauze bag by reserving a certain length of suture and knotting it above the gauze bag; tighten the suture to make the gauze bag exert a certain pressure on the grafted skin, so that the grafted skin is close to the skin tissue For the defect, although the above method has certain positive effects, there are many disadvantages at the same time. The main surface is: 1. The tightness of the dressing cannot be precisely controlled; 2. Since the gauze bag is solid, the pressure on the grafted skin is uneven. Excessive pressure may directly cause ischemia and necrosis of the grafted skin, while too low pressure may cause the grafted skin to fail to adhere closely to the defect wound surface of the skin tissue, thereby failing to rebuild blood circulation and resulting in grafted skin necrosis; 3. It is not easy to find and deal with in time when the wound oozes, and the traditional bandaging method is greatly affected by the doctor's individual experience factors, so it is not easy to standardize the operation
