EXCHANGE SYSTEM FOR AXIAL SPINAL PROCEDURES |
摘要 |
An exchange system is disclosed, for providing a protected path to a subcutaneous procedure site. An exchange cannula is provided with a central lumen, and a drill wire lumen that serves as a portal for a drill wire for coupling the assembly to bone. The wall thickness of the exchange cannula may be eccentric, to accommodate the drill wire lumen within the exchange cannula wall. A tensioning handle may be carried over the exchange cannula, for engaging adjacent tissue. The exchange cannula may have a proximal "T" handle. An exchange rod is movably positionable within the central lumen of the exchange cannula.
