摘要:
A pedicle access device that has particular application for positioning a pedicle screw during a minimally invasive spinal fusion surgical procedure. The pedicle access device includes a positioning needle having a hollow tube and a specially designed tip that conforms with a facet complex of a vertebra proximate a pedicle. A targeting needle having a pointed end is inserted through the hollow tube of the positioning needle, and is secured thereto so the tip of the targeting needle extends out of the end of the positioning needle. The tip of the targeting needle allows the positioning needle to be accurately positioned on the pedicle, and the specially configured tip of the positioning needle allows it to be secured thereto without slipping.
