[0002] Hospitals often receive patients with burns. One type of burn is caused by sticky substances (such as asphalt). The sticky substances need to be removed. When a patient's arm is burned by sticky substances, the common method for this sticky substance is to scrub it with turpentine first, and then apply ice to make the sticky substance harden and clump, which is convenient for peeling. After searching, the existing patent publication number: CN219594954U discloses a wound cleaning device for clinical burn plastic surgery, including a burn debridement frame, an arm support is provided on the upper part of the burn debridement frame, a burned arm is placed on the arm support, a cover is hingedly connected to the top rear side of the arm support, and a cold air pipe network is installed on the inner wall of the cover and the arm support, and a support plate is fixedly connected to the lower part of the burn debridement frame, a semiconductor refrigeration component is provided on the support plate, and a cold air delivery pipe is connected to the upper part of the semiconductor refrigeration component, and a delivery fan is provided on the air inlet side of the cold air delivery pipe, and the cold air delivery pipe is connected to the cold air pipe network, wherein the device can perform surrounding cooling on the burn of the adhesion material on the arm, with a short cooling time and better effect. In the process of realizing the invention, the inventor found that the prior art has the following problems: When the device is in use, the cold air pipe network is used to evenly distribute the cold air in the inner space of the cover and the arm support, so as to quickly cool and harden the adhesive material on the wound surface of the arm. However, when the device is in use, it can only cool the rod-shaped body such as the limbs, and the cooling range is suitable for large-area burns. Some burns that are not on the limbs cannot be cooled. At the same time, when in use, some wounds with a smaller burn range are cooled by the device, which will cause a waste of cost. Therefore, in view of the above problems, a wound surface cleaning device for burn surgery is proposed. Summary of the invention
