1. A three dimensional axis dual drill guide used to align and bore two intersecting bone tunnels within a target bone through two independent bone drill guides contemporaneously set and positioned at locations upon said target bone to drill a transosseous channel within said target bone for further passage of a suture during a joint, cartilage, bone or associated soft tissue repair operation, said drill guide further comprising:
a first guide plate defining a flat circular arc, a joint end, a terminal end and a central arced slide groove; a second guide plate defining a flat circular arc, a joint end, a terminal end and a central arced slide groove, each respective joint end pivotally of each said first and second guide plates connected by a joint which can be disconnected, pivoted at an angle between 180 degrees and 20 degrees, and also secured to maintain an angle between said first guide plate and said second guide plate by a joint securing screw; a first and second slidable guide anchor defining a lower slide trough slidably engaging each respective first and second guide plate and being locked into an independent selected position along each respective guide plate by an anchor locking screw, each slidable guide anchor further defining an upper tangential drill guide channel and a drill guide locking screw which secures a respective drill guide tube within each said respective guide each said drill guide tube forming a tapered end defining at least two tube anchor spikes which are directed into the target bone at respective locations chosen by the surgeon, each said guide channel directing a fixed relative angle between said respective drill guide tubes capable of forming an angle of between 210 degrees and 20 degrees between said drill guide tubes through which bone drill bits are inserted to drill said intersecting bone channels within said target bone. |
