Abstract:
1. A method of harvesting a bone plug from a donor site and implanting it in a recipient site, comprising: orienting a tubular cutting tool relative to a surface of said donor site using an orienting device insertable into said cutting tool, such that a cutting edge at a distal end of said cutting tool contacts said surface during said orienting; harvesting a bone plug from the donor site using said cutting edge; transferring said cutting tool to the recipient site while said bone plug is retained within said cutting tool; and forcing said bone plug out from said cutting tool into said recipient site; wherein said orientating device further comprises (a) a rod located within a tube of said tubular cutting tool, said rod having a smaller outer diameter than the inner diameter of said tube; said rod having a longitudinal axis coaxial with that of said tube, a distal end to be disposed within the end of the said tube to engage a target surface, and a proximal end to project outwardly of the opposite end of the said tube; (b) a head coupled to said rod at its distal end and formed with three contact points arranged in a circular array around the longitudinal axis of the rod such that said three contact points define a plane, said rod being coupled to said three contact points of the head with the longitudinal axis of the rod at said predetermined angle to the plane defined by said three contact points, such that when said three contact points of the head are in contact with the target surface at said plane thereof, and the proximal end of the rod is centered within said tube, the longitudinal axis of said tube is at said predetermined angle with respect to said plane of the target surface;
