Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a debridement device for diabetic foot in endocrinology department. Background Art

[0002] Diabetic foot is a complication of diabetic patients due to long-term poor blood glucose control, which leads to lesions of foot nerves and blood vessels, causing foot ulcers, infections and non-healing complications. It also causes diabetic neuropathy, mainly manifested as decreased or lost sensation, and motor neuropathy leads to contracture of intrinsic foot muscles, resulting in typical claw toe deformities, etc. During treatment, doctors will use physical debridement to remove necrotic tissues, reduce infections, and create good conditions for wound healing. During physical debridement, doctors will use sharp debridement, using tools such as surgical blades to clean the keratinized edges and ulcer bases until bleeding occurs. And if there are signs of infection or necrotic tissues around or under toenails, the toenails also need to be cleaned or partially removed. Generally, the common sites of diabetic foot trauma, especially initial trauma, are: the front part of the sole, between toes or at the toe tips, toe joints, and foot deformity areas such as claw toes.

[0003] During the cleaning process, the most difficult part to clean is the gap between the patient's toes, because the toes cannot be opened as flexibly as fingers, which causes great trouble to the doctor's debridement work. When debriding, doctors usually can only hold the patient's toes apart with one hand and perform debridement with the other hand, which is difficult to operate and inconvenient for debridement. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a debridement device for diabetic foot in endocrinology department. The setting of the fixing mechanism of the device facilitates the fixation of the staff's legs, preventing shaking when cleaning the patient's feet. The spreading mechanism can spread two adjacent toes apart, thus exposing the area to be cleaned between the two adjacent toes, facilitating the staff to clean the gap between the two toes and greatly improving the cleaning efficiency.
