Abstract

A rasp attachment for a motor-driven surgical hand-piece includes a mounting means for mounting the rasp attachment to the motor-driven surgical hand-piece and a rasp area 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. the rasp to is curved and elastically deformable at least in the rasp area.

Claims

1. A rasp attachment for a motor-driven surgical hand-piece, comprising:

a mounting for mounting the rasp attachment to the motor-driven surgical hand-piece; and

a rasp area 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 elastically deformable, at least in the rasp area,

wherein the elastic deformability of the rasp attachment in an area remote from the mounting is higher than in an area close to the mounting.

2. The rasp attachment according to claim 1, wherein the rasp area is arranged at a concave or a convex surface portion of the rasp attachment.

3. The rasp attachment according to claim 1, whose elastic deformability continuously increases from the mounting to an end remote from the mounting.

4. The rasp attachment according to claim 1, having an oblong shape, wherein the mounting is arranged at an end of the rasp attachment and the rasp area is arranged at the opposite end of the rasp attachment.

5. The rasp attachment according to claim 4, which is implemented to take off material from the surface in a movement of the rasp area in the shape of a circular arch segment.

6. The rasp attachment according to claim 4, wherein the rasp area is further implemented to take off material from the surface in a longitudinal direction with a movement of the rasp attachment.

7. The rasp attachment according to claim 1, further comprising an opening facilitating a passage of a rinsing liquid through the rasp attachment.

8. The rasp attachment according to claim 1, wherein the mounting corresponds to an international standard for surgical devices.

9. A motor-driven surgical hand-piece comprising a rasp attachment for a motor-driven surgical hand-piece, comprising:

mounting for mounting the rasp attachment to the motor-driven surgical hand-piece; and

a rasp area 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 elastically deformable, at least in the rasp area,

wherein the elastic deformability of the rasp attachment in an area remote from the mounting is higher than in an area close to the mounting.
