Abstract

Abstract A bone tissue removal and harvesting device is disclosed and includes a cutting tool with a cutting head, a longitudinal shaft attached to the cutting head and a drive element. A container is located on the end opposite the cutting head for collection of the removed bone. The shaft can be made flexible to permit torsion and/or bending around the longitudinal axis without damage to the bone. During the cutting operation, the bone tissue is simultaneously removed and suctioned through an opening of the cutting head and conveyed through an axial shaft bore for collection in the container. The container is detachably mounted to the drive element and connected to the shaft so as to avoid substantial pressure drops from the cutting head to the container.
