Access kits for enabling axial access and procedures in the spine
First Claim
1. An access kit for enabling access to a site in a bone, comprising:
- a guide pin introducer comprising an introducer handle and a rigid elongate introducer tube extending from the introducer handle, the introducer tube having a introducer tube length extending between an introducer tube proximal end and an introducer tube distal end, the introducer tube length configured to extend from a skin incision near the paracoccygeal region through the pre-sacral space to an anterior target point on a sacral vertebral body, the guide pin introducer defining a lumen having a lumen diameter;
a stylet;
a guide pin slideably positionable within the lumen of the guide pin introducer, comprising a solid elongate rod having a rod outer diameter less than the guide pin introducer lumen diameter, a rod length extending between a rod proximal end and a rod distal end, the rod length being greater than the introducer tube length; and
removable a guide pin handle releasably attached to the rod proximal end and configured to allow the guide pin introducer to be proximally withdrawn over the rod proximal end when the guide pin handle is removed from the rod proximal end.

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.
