## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The system of claim 1, wherein the proximal portion of the guide arm comprises at least one radial pin member for engaging at least one slot in the distal end of the handle.

### Claim 3 (depends on 2)

The system of claim 2, wherein the at least one slot is an “L” shaped slot.

### Claim 4 (depends on 2)

The system of claim 2, wherein the at least one slot is an “S” shaped slot.

### Claim 5 (depends on 1)

The system of claim 1, wherein the proximal portion of the guide arm comprises a slot for passage of the guide wire when the guide arm is removed from the guide wire.

### Claim 6 (depends on 1)

The system of claim 1, wherein the tip of the sleeve member is configured to penetrate soft tissue.

### Claim 7 (depends on 1)

The system of claim 1, further comprising a guide wire extending through the internal channel of the sleeve member.

### Claim 8 (depends on 7)

The system of claim 7, wherein a surface of the guide wire comprises a plurality of depth markings to indicate a tunnel length when the guide wire is drilled into bone.

### Claim 9 (depends on 1)

The system of claim 1, wherein a surface of the guide stop comprises a cup for receiving a distal end of the guide wire.

### Claim 10 (depends on 1)

The system of claim 1, wherein the sleeve member is extendable along the insertion axis through a range between the proximal portion of the guide arm and the stop of the guide arm.
