Abstract

A drill guide includes a body, a stabilizing member, a tubular guide sleeve, and an engagement member. The body includes a first channel aligned with a longitudinal axis and a second channel transverse to the longitudinal axis. The first channel is dimensioned to receive the sleeve, while the second channel is dimensioned to receive an engagement member. The engagement member is adapted to move within the second channel between an engaged position, where the engagement member inhibits proximal motion of the sleeve, and a second position, where motion of the sleeve is not inhibited. An alignment member is further mounted to the distal end of the sleeve that includes a distally extending member, spaced from the sleeve. In use, the distally extending member may be employed to exert a force upon a bone or other tissue lateral to the longitudinal axis for improved positioning of the bone or tissue.

First claim

What is claimed is:

1. A method of joint repair, comprising:
securing a drill guide body with respect to a patient's anatomy, the drill guide body including a first channel extending through the drill guide body and aligned with a longitudinal axis of the drill guide body, the first channel dimensioned to receive a drill guide sleeve;
positioning the drill guide sleeve within the first channel, wherein the drill guide sleeve comprises:
a tubular sleeve body extending between a proximal end and a distal end; and
an alignment member attached to the distal end of the sleeve body, the alignment member including an elongated locating member extending distally from the alignment member, wherein the locating member is laterally spaced from the sleeve body by a distally-facing surface;

engaging an engagement member with the drill guide sleeve, the engagement member positioned within a second channel extending through at least a portion of the drill guide body transverse to the longitudinal axis, the second channel intersecting the first channel, the engagement member including a passageway oriented parallel to the first channel when the engagement member is positioned within the second channel, the passageway dimensioned for receipt of a portion of the drill guide sleeve therein; and
sliding the drill guide sleeve distally such that the distal end of the sleeve contacts a first surface of a first bone, such that at least a portion of the drill guide sleeve remains within the first channel of the drill guide body;
wherein at least a portion of the locating member contacts a second surface of the first bone, the second surface being adjacent the first surface.

2. The method of claim 1 , further comprising:
distally advancing a drill bit through the drill guide sleeve; and
drilling a first hole through the first bone.

3. The method of claim 2 , further comprising:
distally advancing the drill bit into contact with a second bone; and
drilling a second hole through the second bone;
wherein the first and second holes are aligned along the longitudinal axis of the drill guide body.

4. The method of claim 3 , wherein the first bone is a clavicle of the patient and the second bone is a coracoid process of the patient.

5. The method of claim 4 , wherein the drill guide body further comprises a stabilizing member including:
a first elongated portion extending distally from the drill guide body, wherein a distal end of the first portion is positioned distally with respect to the distal end of the sleeve; and
a second elongated portion extending from the distal end of the first portion and transversely with respect to the longitudinal axis;
wherein the second portion of the stabilizing member intersects the longitudinal axis.

6. The method of claim 5 , wherein securing the drill guide body to the patient's anatomy further comprises:
positioning the drill guide body on top of the patient's shoulder; and
placing the second portion of the stabilizing member under the patient's scapula.

7. The method of claim 4 , further comprising, after drilling the first and second holes, removing the drill guide body from the patient's anatomy while retaining the drill guide sleeve in place.

8. The method of claim 1 , wherein the drill guide sleeve is not rotated while positioned within the first channel of the drill guide body.

9. The method of claim 1 , wherein the drill guide body further comprises a ratchet mechanism including:
a pawl mounted to the engagement member; and
a plurality of teeth mounted to the drill guide sleeve;
wherein the pawl engages the plurality of teeth in the engaged position of the engagement member to inhibit proximal motion of the drill guide sleeve.

10. The method of claim 9 , wherein the drill guide body further comprises a biasing mechanism positioned within the second channel, wherein the biasing mechanism biases the engagement member in the engaged position.

11. The method of claim 1 , further comprising moving the drill guide sleeve laterally with respect to the longitudinal axis such that the locating member exerts a lateral force on the second surface of the first bone.
