Abstract

An osteotome may include a handle; a shaft coupled to the handle; a cutting member coupled to the shaft, wherein the cutting member comprises a first cutting surface positioned perpendicular to a second cutting surface, and wherein said first and second cutting surfaces extend downward relative to the shaft; and a stop means configured to control the depth of cut by the cutting member.

Claims (23)

1. An osteotome comprising:

a handle;

a shaft coupled to the handle;

a cutting member coupled to the shaft, wherein the cutting member comprises a first cutting surface positioned perpendicular to a second cutting surface, and wherein said first and second cutting surfaces extend downward relative to the shaft; and

a stop extending between and connecting the first cutting surface and the second cutting surface, the stop operable to control the depth of cut by the cutting member, wherein the stop is moveable.

2. The osteotome of claim 1 , wherein the stop has a concave shape.

3. The osteotome of claim 1 , further comprising a moveable plunger coupled to the stop.

4. The osteotome of claim 3 , further comprising a spike coupled to the stop.

5. The osteotome of claim 3 , further comprising a rotatable member coupled to the moveable plunger, wherein the rotatable member is configured to adjust the stop longitudinally relative to said first and second cutting surfaces.

6. The osteotome of claim 3 , further comprising a locking means configured to render said plunger and stop immovable.

7. The osteotome of claim 6 , wherein the locking means is coupled to the handle.

8. The osteotome of claim 1 , wherein the stop cooperates with the first and second cutting surfaces to provide the osteotome with a substantially triangular cross-section at the stop.

9. The osteotome of claim 8 , wherein the stop is recessed from a distal end of the first cutting surface and the second cutting surface.

10. The osteotome of claim 8 , wherein the stop defines an opening bounded by the first cutting surface, the second cutting surface, and the stop.

11. The osteotome of claim 8 , wherein the stop is attached to the first cutting surface and the second cutting surface at a junction of the first cutting surface and the second cutting surface.

12. The osteotome of claim 11 , wherein the stop extends in a direction away from the junction along a length of the first cutting surface.

13. The osteotome of claim 12 , wherein the stop extends in a direction away from the junction along a length of the second cutting surface.

14. The osteotome of claim 1 , wherein the stop is recessed from a distal end of the first cutting surface and the second cutting surface.

15. The osteotome of claim 1 , wherein the stop defines an opening bounded by the first cutting surface, the second cutting surface, and the stop.

16. The osteotome of claim 1 , wherein the stop is attached to the first cutting surface and the second cutting surface at a junction of the first cutting surface and the second cutting surface.

17. The osteotome of claim 16 , wherein the stop extends in a direction away from the junction along a length of the first cutting surface.

18. The osteotome of claim 17 , wherein the stop extends in a direction away from the junction along a length of the second cutting surface.

19. The osteotome of claim 1 , wherein the stop is formed at an acute angle relative to the first cutting surface and relative to the second cutting surface.
