Abstract
Surgical drill guides have modular configurations and are adapted to accommodate a wide range of anatomy. The surgical drill guides are adapted to be removed while leaving a guide wire in its intended location in human bone. The distal end of the drill guide acts as a safety stop for the guide wire by preventing the guide wire from penetrating too far past the far side of the bone.
Claims10
A surgical drill guide system comprising:
- an elongate handle having a proximal end, a distal end, and a longitudinal axis extending therebetween, an internal cannulation extending a length of the handle between the proximal end and the distal end;
- a sleeve member configured to slideably extend through the cannulation having an internal channel for passage of a guide wire and defining an insertion axis;
- and
- a guide arm removeably coupled to the distal end of the handle, the guide arm having a proximal portion rotatable relative to the handle, and a distal arcuate portion terminating in a stop disposed at a point along the insertion axis;
- wherein a tip of the sleeve member and the stop of the guide arm define a drilling path therebetween for the guide wire along the insertion axis;
- and
- wherein a surface of the sleeve member comprises a plurality of grooves for selective engagement with a ratcheting member extending into an interior of the handle, the ratcheting member selectively engaging under spring force into each one of the plurality of grooves such that the sleeve member can be advanced progressively until resisted by bone.
