Abstract
A device is designed for scraping off disordered part at the surface of soft tissues, particularly for removing diseased surface tissues deep in an ear canal. The device mainly includes a handle having a battery-powered motor mounted therein, and a scraper in the form of a hollow tube having two open ends, a front end of which is a scraper tip having a saw-toothed edge, and a rear end of which is connected to a front end of the handle and an external suction hose. When the motor is actuated, the handle and accordingly the scraper are vibrated to result in a circular motion of the scraper tip, enabling the scraper tip to scrape and exfoliate diseased tissues while the suction hose synchronously sucks effused blood and exfoliated tissues, so that the treated area is clean and easy for observation during an operation.
