Abstract
A threaded bone anchor retriever and method for retrieving threaded bone anchors and the like from an implantation site. The anchor retriever is particularly suitable for retrieving threaded suture anchors during endoscopic surgical procedures. The retriever comprises an elongated shaft having an anchor engaging means at its distal tip for engaging the drive portion of the threaded anchor and for turning it in a direction to remove it from the implantation site. A concentric anchor engaging sleeve is adapted to move longitudinally relative to the elongated shaft in order to engage the threaded body of the anchor as it is removed from the implantation site. The invention includes a method for using the anchor retriever, particularly during endoscopic procedures, to remove anchors which may or may not have tissue growth overlying the implantation site.
