A device is designed for scraping off the diseased part at the surface of soft tissues, particularly for removing diseased tissues deep in an ear canal. The device mainly includes a handle internally provided with a vibrating motor having an eccentric wheel mounted on a rotary shaft of the motor, and a plurality of batteries; and a tubular scraper having two open ends, a front end of which is a scraper tip having a toothed front edge, and a rear end of which is connected to a front end of the handle and communicates with a suction hose. When the motor is actuated, the handle and the scraper are vibrated for the scraper tip to scrape and exfoliate diseased tissues while the suction hose synchronously sucks out effused blood and exfoliated tissues, so that the treated area is clean for easy observation during an operation.
