Soft tissue debridement knife based on endoscope technology

Abstract

The invention relates to a soft tissue debridement knife based on the endoscope technology. The soft tissue debridement knife comprises a soft tissue debridement knife body, a soft tissue debridementknife catheter, a handle and an insertion tube; the front end of the insertion tube is provided with a soft tissue debridement knife outlet, a light exit port, an objective lens and a CCD image sensor; the handle is provided with an image processor, a cold light source, a soft tissue debridement knife inlet, a soft tissue debridement knife adjuster, a central processor and a touch control displayscreen. The soft tissue debridement knife has the advantages that the position, depth, complexity and adjacent relationship with important blood vessels, nerves and organs of the chronic deep ulcer and the skin soft tissue sinus tract can be accurately evaluated; besides, through a funnel-shaped filter screen and a gear-shaped knife head of the knife, the deep ulcer and the sinus tract can be effectively removed by rotating the knife head under direct vision with an endoscope; through an electrocoagulation device, a bleeding part can be quickly and accurately stopped from bleeding after debridement; through a negative-pressure suction head, necrotic tissue can be quickly and thoroughly sucked out of the body.

Description

technical field [0001] The invention relates to the field of soft tissue debridement instruments, in particular to a soft tissue debridement knife based on endoscopic technology. Background technique [0002] After skin and deep soft tissue injury, due to systemic and local factors, about 5-10% of patients develop chronic deep ulcers and sinus tracts, resulting in prolonged wound healing, which causes heavy economic and psychological burdens to patients and their families. With the early arrival of my country's aging society, chronic deep ulcers, high morbidity and high disability rates of skin and soft tissue sinuses have gradually become increasingly serious social and medical problems. [0003] The reason why chronic deep ulcers and skin soft tissue sinuses are difficult to heal is mainly due to the existence of systemic and local incentives. Systemic factors include: malnutrition, hypoperfusion, obesity, diabetes, hormone drugs, systemic infection, immunosuppressants, e...

Problems solved by technology

On the one hand, the traditional surgical method needs to enlarge the incision to facilitate the complete removal of necrotic tissue, which leads to excessive surgical incision and excessive loss of normal tissue, which significantly increases the hospitalization time and hospital expenses of patients; on the other hand, conventional surgical treatment It is difficult to accurately judge the wound surface and the complexity of the sinus before and after the debridement operation, which can easily lead to deep ulcers and sinus recurrence due to incomplete surgical debridement
