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. 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.

2. A disc preparation kit as in claim 1, comprising at least three cutters.

3. A disc preparation kit as in claim 1, comprising at least three tissue extraction tools.

4. A disc preparation kit as in claim 1, further comprising a bone graft inserter.
