摘要：
Methods and devices for harvesting cancellous bone are disclosed. The bone-harvesting device may include a cannula and a bone receptacle in communication with the cannula, wherein the cannula including a cutting surface positioned at or adjacent the distal end, the cutting surface being oriented at an angle, the angle being greater than 90 degrees relative to the longitudinal axis of the cannula, and the harvested bone is adapted to move from a position adjacent to the cutting surface through the cannula into the bone receptacle. The cutting surface of the cannula may be positioned at or adjacent the distal end, and positioned at least in part radially outward of the outer face of the cannula. The cannula may include a cutting surface positioned at or adjacent the distal end and an occluding geometry that partially occludes the distal end of the cannula adjacent the cutting surface. In addition, a suction port may be provided in communication with the bone receptacle.
