Abstract

An apparatus and method for creating a space of defined length, height, width and shape with a vibrating cutting apparatus in preparation for receiving an interbody spinal implant or graft of known size and configuration is disclosed.

Claims

1. A device for creating a cavity between or at least partially within two or more bones or bone surfaces by means of a vibrating cutting tool where said cutting tool is shaped substantially like the desired bone cavity

2. The device of claim 1, where said cutting tool is placed adjacent to, and creates a cavity between, said bones

3. The device of claim 1, where said cutting tool is placed adjacent to, and creates a cavity within, said bones

4. The device of claim 1, where said cutting tool is passed along or within a cutting guide

5. The device of claim 4, where said cutting tool is rotated within or around said cutting guide to create said cavity

6. The device of claim 4, Where said cutting guide also acts as a spacer to maintain a fixed distance between said bones

7. The device of claim 1, where said cavity is shaped to fit an implant

8. The device of claim 7, where said implant is made of a biologically compatible material

9. The device of claim 4, where said cutting tool has a cavity for said cutting guide

10. The device of claim 1, where said cutting tool has a cavity for collection of bone debris

11. The device of claim 1, where said cutting tool has perforations through its bone-contacting surface for passage of irrigation or bone debris

12. The device of claim 1, further comprising a depth stop

13. A device for creating a cavity between or at least partially within two or more bones or bone surfaces by means of an orbiting cutting tool where said cutting tool is shaped substantially like the desired bone cavity

14. The device of claim 13, where said cutting tool is placed adjacent to and creates a cavity between said bones

15. The device of claim 13, where said cutting tool is placed adjacent to and creates a cavity within said bones

16. The device of claim 13, where said cutting tool is passed along or within a cutting guide

17. The device of claim 16, where said cutting tool is rotated within or around said cutting guide to create said cavity

18. The device of claim 16, where said cutting guide also acts as a spacer to maintain a fixed distance between said bones

19. The device of claim 13, where said cavity is shaped to fit an implant

20. The device of claim 19, where said implant is made of a biologically compatible material

21. The device of claim 16, where said cutting tool has a cavity for said cutting guide

22. The device of claim 13, where said cutting tool has a cavity for collection of bone debris

23. The device of claim 13, where said cutting tool has perforations through its bone-contacting surface for passage of irrigation or bone debris

24. The device of claim 13, further comprising a depth stop
