Abstract

The invention discloses a debridement device for operation of the general surgery department and relates to the field of clinical medicine. The debridement device comprises a pressurizing device, a storage tank and a handpiece, wherein the pressurizing device provides high-pressure gas for the storage tank and is connected with a gas inlet of the storage tank through a high-pressure gas pipe; thestorage tank comprises two or more independent storage units in parallel, and each storage unit comprises a barrel, a gas inlet pipe arranged at the top end or the upper end of the side surface of thebarrel and extending into the barrel as well as a liquid discharging pipe arranged at the top end or the upper end of the side surface of the barrel and extending into the inner bottom end of the barrel; the handpiece is connected with a liquid discharging port of the storage tank through a handheld header pipe, and a check valve is arranged at the tail end of the liquid discharging pipe; a valveis arranged on the liquid discharging pipe. The effect of one-time completion of mechanical debridement, debridement with a sharp instrument, debridement with enzyme and debridement with a disinfectant for a wound through one device is realized on the whole.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a debridement device for general surgery. Background technique [0002] The wound healing process includes four stages: 1. The wound has tissue necrosis and blood vessel rupture, and there will be an inflammatory reaction, blood vessel congestion, and inflammatory cell exudation, so it will be red and swollen. The blood and fibrinogen oozing from the wound coagulate into clots, forming a scab, which protects the wound. 2. After 2-3 days of wound contraction, the muscle layer fibroblasts in the skin and subcutaneous tissue of the wound proliferate, pulling the edge of the wound to move to the center, shrinking the wound. . 3. Granulation tissue hyperplasia and scar formation From the third day, granulation tissue grows at the bottom and edge of the wound, which is usually caused by fibroblast proliferation, and the granulation tissue is rich in blood vessels. After 5-6 days, ...
