PROBLEM TO BE SOLVED: To provide an instrument for shaving a material from a bone. SOLUTION: The surgical instrument comprises a handle 10, which bears a blade 20 having a scraping edge, and a collection chamber R for the shaved material. The collection chamber R exhibits a mouth part for communication with an external environment, located in proximity of the scraping edge, for an inlet of the shaved material. The mouth part is closed in order to prevent passage of the material stored in the collection chamber R. A portion of the instrument is elastically deformable in order for the communication mouth part to be opened during a scraping operation by the scraping edge. A wall 30 is exhibited, which, together with the handle 10, delimits the collection chamber R; the wall 30 having an end portion in proximity of the blade 20, which end portion is separated, the communication mouth part being located at a front end part of the end portion. A portion of the handle is elastically deformable in order to distance the end portion of the wall 30 from the handle 10 when the instrument is pressed with the blade 20 against a bone, and to near the handle 10 when the instrument is not subject to mechanical solicitation.
