ABSTRACT:
The invention is in a double guide sleeve drill guide for use in an arthroscopic surgical procedure for replacement of a cruciate ligament in a straight ligament tunnel procedure that involves forming intersecting tunnels to the femoral and tibial sections of which straight ligament tunnel. The drill guide of the invention includes straight parallel reference and guide rods that are in the extend from a web member at right angles and are in the same plane, forming a U-shaped device, with the reference rod arranged for fitting into which straight ligament tunnel. The connection of which reference rod to the web member is adjustable along the web member for setting a spacing distance between which reference and guide rods, and equidistant markings are scribed along the reference rod as a scale. The guide rod mounts a pair of blocks, one fixed and one movable, with threaded holes formed through each for receiving a guide sleeve wherethrough a drill is turned, guiding drilling of holes that intersect which femoral and tibial tunnel sections. The fixed block is slightly movable to spread apart the threaded guide sleeve hole that is formed as two segments, to allow for passage of a drill sleeve slid therein. The two threaded guide sleeve hole sections are closed together to mesh with a guide sleeve threaded body portion, and a slot is formed in the guide rod that intersects the fixed block threaded guide sleeve hole to allow a drill or K-wire to pass therethrough.
