Summary:A tool system for facilitating medical procedure including accessing a selected bone structure or tissue structure includes a cannula and an obturator with a drill section formed on its distal end. Additionally a drill guide may protrude from the distal end of the obturator. The disclosed tool system may be used to penetrate the cutaneous layers of a patient until the drill guide penetrates the exterior surface of a target bone structure such as a vertebral body. The system may then be rotated and torqued to allow the drill section of the obturator to bore into the bone structure. As the system advances, the cannula translates forward within the bore created by the drill section until a desired placement of the cannula is achieved.
