Abstract:
1. A rasp attachment for a motor-driven surgical hand-piece, comprising: a substantially axial member comprising a first terminal end and a second terminal end wherein the substantial axial member is configured with decreasing thickness in the direction from the first terminal end towards the second terminal end; a mounting on the first terminal end for mounting the rasp attachment to the motor-driven surgical hand-piece, wherein the rasp attachment is configured such that, during rasp operation the second terminal end is a free end; and an integral rasp area on the second terminal end which is implemented to take off material from a surface in a reciprocating movement of the rasp attachment caused by the motor-driven surgical hand-piece, wherein the rasp attachment is curved and at least partially elastically deformable in the rasp area such that the rasp area may be deformed to a given shape, and wherein the rasp area is sufficiently rigid to maintain its given shape when driven over bone substance by a motor-driven surgical hand-piece, wherein the substantially axial member comprises at least one region having a elasticity higher than the elasticity in at least one other region due to the decreased thickness wherein the integral rasp area is located in the region having a higher elasticity than the other region and wherein the second terminal end and the integral rasp area are convex in a transverse direction with respect to a longitudinal extension of the rasp attachment.
