Abstract
A drill bit configured for maximum bone penetration harvests and morselizes bone fragments from a harvest site for use in reparative bone grafting. A suction port on a removable harvest cap enables the bone fragments and irrigation fluids to be drawn into a distal end of a cannula portion of a collection reservoir. A filter screen mounted within the chamber of the collection reservoir enables the irrigation fluids to be removed while the bone fragments are retained in the reservoir. A retention plug can be inserted into the distal end of the cannula to allow the removable cap and drill to be removed. The reservoir can be transported to a reparation site, the retention plug removed and a plunger inserted into the open upper end of the collection reservoir to deliver morselized bone fragments out of the distal end of the cannula to the site to be restored. By replacing the harvesting cap with a collection cap which has a larger suction port, the system can be optimized for recovering morselized bone fragments which have been harvested by an earlier drilling operation.
