Bone-tendon-bone drill guide
First Claim
1. A bone-tendon-bone drill guide comprising, a pair of scissor arms connected together by a pivot whereby moving together of lower hand engaging portions of said scissor arms moves scissor arm top ends together;
- a pair of opposing first and second jaw means that are each mounted at approximately their horizontal center to extend across and at approximately a ninety (90) degree angle to a scissor arm top end and each jaw means having a half cylindrical surface formed along its longitudinal axis that are in opposition to one another forming, when said scissor arm top ends are closed together essentially an open cylinder;
a pair of parallel drill guide means mounted at spaced points along a longitudinal axis of said first jaw means each having a guide hole formed therethrough with the other or second jaw means including like openings therethrough that each align with one of said drill guide means guide holes and have a greater diameter than each said guide hole; and
means for locking in place said scissoring arms after said jaw means have been closed together over an item to be drilled.

Abstract
A bone-tendon-bone drill guide for use is guiding drilling to form a pair of transverse holes through a bone end of a bone-tendon-bone ligament graft to receive a suture or sutures threaded therethrough to form a suture sling or craddle supporting the bone end as the suture are pulled into a tunnel section of a straight that has been formed into a patient'"'"'s bone. The drill guide includes a pair of scissor arms connected at a pivot that are formed to where moving of lower hand engaging portions of the arms together also moves upper ends of the arms together whereacross opposing jaws are maintained. The jaws each include curved surface therealong for engaging a bone end fitted therebetween and each preferably includes spikes that extend from a jaw face for engaging, to hold in place, the bone end as a drill is turned through straight drill guide holes formed through a jaw to form transverse holes through the bone end, with the drill to exit the bone end and pass through openings formed through the other jaw. To lock the jaws in place, the drill guide further includes a straight brace that is pivotally connected to the lower end of one scissoring arm to pivot an edge thereof into alignment with a single tooth that extends from the bottom end of the other scissoring arm, the straight brace including a series of teeth formed along its edge to engage the single tooth and is spring biased to urge the series of teeth against the single tooth, urging a meshing engagement therebetween.
