ABSTRACT:
A tool for guiding a surgical drill bit through the center of a target obstruction within a bone. An adjustable frame includes a pair of right angle sections mounted in a mirror image relationship. The sections are adjustably clamped to one another and, in turn, secure a vertical sleeve for guiding a surgical drill bit and a horizontal sleeve for accommodating an anchor pin within a coplanar arrangement. Various clamps associated with the frame elements and the sleeves permit a surgeon to adjust the tool so that the drill bit is guided through the vertical sleeve to the approximate center of the bone immediately below the obstruction while the pin anchors the frame to the bone.
