Multi-barrel drill guide
A multi-barrel drill guide with an elongated body extending along a longitudinal axis having a proximal end and a distal end, an elongated distal guide tube attached to and extending from the distal end of the elongated body, and a handle extending from the elongated body between the proximal end and the distal end. The elongated body has a first channel extending from the proximal end to the distal end and a second channel extending from the proximal end to the distal end at an angle relative to the first channel. The first channel and the second channel intersect at a convergence area at the distal end. A drill bit is movable in a slidable manner within the second channel, and a driver loaded with a suture anchor is movable in a slidable manner within the first channel.
1. A method of drilling a pilot hole and inserting a suture anchor, the method comprising the steps of:
providing a multi-barrel drill guide with an elongated body extending along a longitudinal axis having a proximal end and a distal end with a handle extending from the elongated body between the proximal end and the distal end, and an elongated distal guide tube attached to and extending distally from the distal end of the elongated body, wherein there is no movable part on an exterior portion of the elongated body, a first channel extending from the proximal end to the distal end, a second channel extending from the proximal end to the distal end at an angle relative to the first channel, and a convergence area at the distal end where the first channel and the second channel intersect;
inserting a suture anchor into the first channel and a drill bit into the second channel;
positioning the distal end of the distal guide tube against a bone;
extending the drill bit through the convergence area and the distal guide tube; and
drilling a pilot hole into the bone with the drill bit.
2. The method of claim 1 , further comprising the steps of:
retracting the drill bit past a proximal end of the convergence area; and
extending an anchor driver through the first channel and the convergence area.
3. The method of claim 2 , further comprising the step of implanting the suture anchor into the pilot hole.
4. The method of claim 3 , further comprising the steps of:
pulling a length of suture connected to the suture anchor through a slit in the exterior of the elongated body that extends into the first channel; and
removing the drill guide from the bone.
5. The method of claim 1 , wherein the drill guide further comprises a malleting section extending proximally from the handle and a plurality of teeth on the distal end of the elongated body.
6. The method of claim 5 , wherein the step of positioning the distal end of the drill guide against the bone further comprises the step of striking the malleting section such that the plurality of teeth grip with the bone.
7. The method of claim 2 , further comprising the step of disengaging a locking mechanism from the anchor driver such that the anchor driver can freely move through the first channel.
