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;
wherein the handle comprises a first diameter and the guide shaft comprises a second diameter, the first diameter being greater than the second diameter;
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 contact surface extending from the recess;
a fin extending from an exterior surface of the recess, the fin having the contact surface thereon;
wherein the fin is substantially triangular;
wherein the fin extends from the channel to a proximal edge of the recess;
wherein the guide shaft extends to a distal crown end; and
wherein the distal crown end comprises a plurality of protrusions extending distally therefrom.
2. 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;
wherein the handle comprises a first diameter and the guide shaft comprises a second diameter, the first diameter being greater than the second diameter;
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 protrusions extending from the recess, each protrusion having a proximal contact surface,
wherein the plurality of protrusions are substantially triangular;
wherein each of the plurality of protrusions extends from the channel to a proximal edge of the recess;
wherein the guide shaft extends to a distal crown end; and
wherein the distal crown end comprises a plurality of protrusions extending distally therefrom.
