Abstract

The present invention pertains generally to a surgical tool for cutting and shaping bone, cartilage and other anatomical structures. In particular, described herein are surgical tools having at least two cutting surfaces.

Claims

1. A surgical device for cutting and removing target tissue such as cartilage and bone within a body, said device comprising:

a handle; and

a cutting element attached to the handle, the cutting element comprising at least two cutting surfaces, wherein the cutting surfaces cut tissue when the device is pushed or pulled along the target tissue.

2. The device of claim 1, wherein the cutting surfaces are blades.

3. The device of claim 1, wherein the cutting surfaces are abrasion surfaces.

4. The device of claim 1, wherein the cutting surfaces are disposed on opposite sides of the cutting element.

5. The device of claim 1, wherein the cutting surfaces are disposed on the same side of the cutting surface.

6. The device of claim 1, further comprising a carrier, wherein the cutting element is disposed within the carrier.

7. The device of claim 1, wherein the cutting element is curved on at least one of the two cutting surfaces.

8. The device of claim 1, wherein each of the two cutting surfaces is curved.

12. A kit comprising one or more surgical devices according to claim 1 and one or more joint implants.

9. A surgical device for cutting and removing target tissue such as cartilage and bone within a body, said device comprising:

a handle; and

cutting means attached to the handle, the cutting means comprising at least two cutting surfaces, wherein the cutting means cuts tissue when the device is pushed or pulled along the target tissue.

10. The surgical device of claim 9, wherein the cutting means is curved on at least one of the two cutting surfaces.

11. The surgical device of claim 9, wherein each of the two cutting surfaces is curved.

13. A surgical device for revising a cartilage surface comprising:

a handle;

a carrier attached to a proximal end of the hand position substantially within a plane; and

a cutting element disposed within the carrier such that a blade of the cutting element is at an angle relative to the plane of the carrier.

14. The surgical device of claim 13, wherein the handle and the cutting element are formed integrally.

15. The surgical device of claim 13, wherein the cutting element is removable.

16. The surgical device of claim 13, wherein the cutting element has a plurality of blades.

17. The surgical device of claim 13, wherein the cutting element has at least two blades.

18. The surgical device of claim 13, wherein the cutting element has two cutting surfaces disposed such that the surface oppose each other.

19. The surgical device of claim 13, wherein the cutting surfaces are pivotally mounted.
