Abstract
A system and a method for positioning a drill, having a drill bit with a central axis, for drilling a subsequent hole in a bone at a predetermined distance from and in a predetermined orientation in respect to a reference hole, is disclosed. The system comprises a reference insert, configured to be inserted into the reference hole, and adapted to establish a reference guideline, the reference guideline being of the predetermined orientation; and, an alignment mechanism, configured to be attached to the drill, the alignment mechanism adapted to be fixed at the predetermined distance from and parallel to the central axis of the drill bit, the alignment mechanism including an optical device for colinearly aligning an alignment axis of the alignment mechanism with the reference guideline.
