摘要

Device for withdrawing flakes or shavings from a donor bone by scraping, comprising an internally hollow handle (M) composed of a hollow body (1) with a cavity (11) and of slidable means for closing and respectively rendering accessible the cavity (11), and scraper means (20) positioned at the front end of said slidable means and comprising a gap for passage of the bone flakes or shavings into the cavity (11); said slidable means comprise an upper plate (6) positioned on the upper side of the hollow body (1) to close the cavity (11) and slidable on this latter, its front portion (7) being not joined to the hollow body (1) and being elastically deformable to move away from the front edge of this latter when under load. Said scraper means comprise a blade (20) positioned at the front end of said slidable plate (6), and having an active surface (21) perpendicular or nearly perpendicular to the longitudinal axis of the front portion of the handle (M).
