Drill guide assembly
A drill guide to facilitate drilling a hole into a bone and inserting an anchor. The drill guide includes a handle extending to a proximal end and a guide shaft extending from the handle to a distal end. A recess extends into the handle at the proximal end. The drill guide also includes a channel extending through the recess and into the guide shaft and a contact surface extending from the recess. The contact surface may be a proximal surface on a ring extending circumferentially within the recess. The contact surface may alternatively be a proximal surface on a protrusion extending from and within the recess. For example, the protrusion is a triangular protrusion extending along the recess toward the channel. The contact surface allows for the use of inserters of varying sizes within the channel of the drill guide.
1. A drill guide extending along a longitudinal axis with a proximal end and a distal end, the drill guide comprising:
a handle extending from a distal end of the handle to the proximal end of the drill guide;
a guide shaft extending from the distal end of the handle to the distal end of the drill guide;
a recess extending into the handle at the proximal end of the drill guide;
a channel extending through the recess and into the guide shaft;
a plurality of rings extending circumferentially within the recess and from an exterior surface of the recess; and
wherein each of the plurality of rings has a proximal contact surface.
2. The device of claim 1 , wherein the plurality of rings are spaced along the exterior surface of the recess.
3. The device of claim 1 , wherein one of the plurality of rings extends to a proximal edge of the recess.
4. The device of claim 1 , wherein one of the plurality of rings extends around and abuts the channel.
