Abstract
A system for performing a minimally invasive surgical procedure comprises a cannula, a bone filler material delivery nozzle for performing the procedure through the cannula, and a retainer for securing the delivery nozzle relative to the cannula. The retainer eliminates the need to manually stabilize and position the delivery nozzle during the procedure, thereby allowing the physician to perform the procedure outside of the fluoroscopic radiation field used to visualize the procedure location. The retainer can be attached to the cannula, and can provide either selective or constant clamping force onto the delivery nozzle.
