Negative pressure curette for surgical debridement

Abstract

The invention relates to the technical field of medical equipment application, in particular to a negative pressure curette for surgical debridement. The negative pressure curette comprises a handle of a hollow structure, a curette handle of a hollow structure and a curette head; the handle is connected with a negative pressure suction pipe; the negative pressure suction pipe communicates with the curette handle; the side wall of the handle is connected with a negative pressure valve; the negative pressure valve is connected with the negative pressure suction pipe; and the bottom part of the handle is connected with two illuminating lamps oppositely arranged. According to the negative pressure curette, a traditional solid curette is changed into the curette of the hollow structure; the negative pressure suction pipe is connected onto the handle; necrotic tissue can be sucked away in time through the negative pressure suction pipe during curettage operation, and deep infected tissue difficult to remove through washing and wiping is sucked out, thus avoiding that the infected tissue spreads to the deep part to enlarge the pollution area; meanwhile, the operation speed is increased, the surgery efficiency is improved, and the negative pressure curette can be popularized in all levels of medical institutions.

Description

technical field [0001] The invention relates to a curette for surgical debridement, in particular to a negative pressure curette for surgical debridement, which belongs to the application field of medical equipment. Background technique [0002] The curette is the most commonly used instrument in surgical debridement, and is usually used to scrape deep infected tissues. When the existing curette is used, a large amount of granulation scraped off is usually piled up together, which needs to be washed with gauze or saline again to remove it, but it is difficult to remove it by general methods during deep sinus operation, and the scraped off scraped off in time When the tissue is removed and the curette is used continuously, the residual tissue on the curette will remain in the sinus along with the movement of the curette, expanding the area of ​​infection. Contents of the invention [0003] In order to overcome the deficiencies of the existing curettes, the invention provid...
