<p>The tool comprises a handle (10) which bears a scraping blade (30) placed at the front end of the handle (10) and adapted to scrape particles from a bone, a collection chamber (20) of the removed material inside the front end portion of the handle (10), and a passage opening (21) in the collection chamber (20), placed near the scraping blade (30), which permits the passage of the scraped particles within the chamber (20). According to the invention, the collection chamber (20) has nearly cylindrical form and the tool comprises a collection means (40) of the particles having tubular form, insertable and extractable from the collection chamber (20) itself. The collection means (40) comprises a tubular covering (41), adapted to contain the bone particles scraped from the blade (30), whose front end portion (41') has a section adapted to substantially occupy the entire section of the collection chamber (20), for collecting the particles from the chamber (20) itself.</p> |
