Appl. No.:

Abstract:

A bone harvesting tool includes an elongate hollow collection cannula with a lumen for receiving harvested bone tissue. Holes are formed through the collection cannula to permit visual observation of the volume of bone tissue that has been collected. Cutting blades are mounted to the distal end of the collection cannula and are configured for cutting into bone tissue. The cutting blades are aligned so that the harvested bone tissue advances proximally into the lumen of the collection cannula. A guide pin is telescoped into the collection cannula and through the blades. The guide pin is employed for initial positioning of the tool on the bone. A plug near the distal end of the guide pin enables the guide pin to be used for expelling the collected bone tissue from the collection cannula.

Abstract:

A spinal distraction apparatus includes substantially parallel fixed and movable legs, each of which has opposite front and rear ends. A rear rod projects rigidly from the rear end of the fixed leg and passes slidably through the rear end of the movable leg. A front rod extends rigidly from the fixed leg and is parallel to the rear rod. The front rod is formed with an array of external threads and nuts are threadedly engaged on the external threads for engaging opposite sides of the movable leg at locations adjacent the front rod. Thus, the position of the movable leg relative to the fixed leg can be controlled by adjusting the positions of the nuts. Front ends of the fixed and movable legs have attachments mounted thereto for engaging pedicle screws or other structures used in spinal distraction surgery.
