Abstract

Disclosed are surgical tools, tool sets and methods for percutaneously accessing and preparing treatment sites within the spine for subsequent treatment procedures. The treatment site may be an inter-vertebral motion segments in the lumbar and sacral regions of the spine. The tool set may comprise introducer tools and bone dilators for accessing and tapping into a targeted site, such as, for example, the anterior surface of the S1 vertebral body. The tool set may also comprise cutters and extractors for preparing the treatment site for subsequent treatment procedures. The tool set may additionally comprise a bone graft inserter, an exchange system, and/or a temporary distraction tool for further preparing the treatment site for subsequent treatment procedures.

Claims

1. An access kit for enabling access to a site in a bone, comprising:

a guide pin introducer;

a stylet;

a guide pin; and

a guide pin handle.

2. An access kit as in claim 1, further comprising a guide pin extension.

3. An access kit as in claim 1, further comprising at least one bone dilator.

4. An access kit as in claim 1, further comprising at least two bone dilators.

5. An access kit as in claim 1, further comprising at least one bone dilator with a removable sheath.

6. An access kit as in claim 1, further comprising at least one cannulated slap hammer.

7. An access kit as in claim 1, further comprising at least one twist drill.

8. A disc preparation kit, for preparing a disc space for a subsequent procedure, comprising:

at least one cutter, for disrupting material in the disc space; and

at least one tissue extraction tool, for extracting disrupted material from the disc space.

9. A disc preparation kit as in claim 8, comprising at least three cutters.

10. A disc preparation kit as in claim 8, comprising at least three tissue extraction tools.

11. A disc preparation kit as in claim 8, further comprising a bone graft inserter.

12. A spinal fusion kit, comprising:

an access tool, for providing access to a disc space;

a cutter, for disrupting material in the disc space;

a tissue extraction tool, for removing disrupted material from the disc space; and

a fusion rod, for spanning the disc space and enabling fusion of adjacent vertebral bodies across the space.

13. A spinal fusion kit as in claim 12, further comprising a bone growth material inserter.

14. A spinal fusion kit as in claim 12, further comprising a bone paste inserter.

15. A mobility kit, comprising:

an access tool, for providing access to a treatment site;

a cutter for disrupting material in the treatment site;

a tissue extraction tool, for removing disrupted material from the treatment site; and

a mobility device, for spanning at least a portion of the treatment site and enabling motion across the treatment site.

16. A mobility kit as in claim 15, further comprising an augmentation material inserter.

17. A mobility kit as in claim 15, further comprising a driver tool for delivering the mobility device to the treatment site.

18. A mobility kit as in claim 17, wherein at least a portion of the driver tool comprises a hexagonal cross section.

19. A mobility kit as in claim 15, wherein the treatment site comprises a disc.
