Abstract

Devices, systems, and methods are provided for ligament repair procedures, and can be used to establish a location and trajectory for forming a bone tunnel in bone. One exemplary embodiment of a surgical guide for using in a ligament repair procedure includes a guide arm and a carriage that can be selectively locked along the guide arm to define an angle of the bone tunnel. The guide arm also defines a location of a distal end of the bone tunnel. In some embodiments the carriage is configured to have a bullet side-loaded into it, and the bullet can be used to define a location of a proximal end of the bone tunnel. The present disclosure also provides for a gage that limits the distance a drill pin that drills the bone tunnel can travel. A variety of other, devices, systems, and methods are also provided.

First claim

What is claimed is:

1. A method for drilling a tunnel in bone, comprising:
grasping a first arm of a ligament guide system in a palm of a hand, fingers of the hand being wrapped around the first arm;
positioning a second end of a second arm of the ligament guide system adjacent to a desired location for a distal end of a tunnel to be drilled in bone;
positioning a first end of the first arm of the ligament guide system proximate to an opposed side of the bone, the side at which a proximal end of the tunnel to be drilled in bone is to be located;
sliding a carriage disposed on the first arm along a length of the first arm and locking a location of the carriage with respect to the first arm to set a trajectory of the tunnel to be drilled in bone, wherein the carriage is able to be slid along the first arm while the hand grasping the first arm maintains the grasp such that the hand does not move with respect to the first arm; and
passing a drilling tool through an opening formed in the carriage to drill a tunnel in the bone from the side of the bone at which the first end of the first arm is located to the side of the bone at which the second end of the second arm is located.

2. The method of claim 1 , further comprising:
positioning a bullet in the opening formed in the carriage; and
positioning a distal end of the bullet adjacent to a desired location for the proximal end of the tunnel to be drilled in bone,
wherein passing a drilling tool through an opening formed in the carriage includes passing the drilling tool through the bullet.

3. The method of claim 2 , further comprising:
disassociating the bullet from the first arm such that the ligament guide system is removed from the surgical site without removing the drilling tool from the bullet; and
passing the drilling tool from the distal end of the tunnel to the proximal end of the tunnel to expand a diameter of the tunnel.

4. The method of claim 1 , wherein the first arm has a plurality of slots formed therein and the carriage includes a passively engaging male member that is configured to engage a slot of the plurality of slots to lock a location of the carriage with respect to the first arm to set the trajectory of the tunnel to be drilled in bone.

5. The method of claim 4 , further comprising:
actively disengaging the male member from the slot;
moving the carriage along the first arm; and
allowing the male member to engage a slot of the plurality of slots to lock the location of the carriage on the first arm.

6. The method of claim 1 , wherein the first arm of the ligament guide system is configured to be grasped by a right hand or a left hand and used in performing the method when disposed in either the left hand or the right hand.

7. The method of claim 1 ,
wherein the first arm has a first facial surface, a second facial surface that is opposed to the first facial surface, a first side surface extending between the first and second facial surfaces, a second side surface extending between the first and second facial surfaces and being opposed to the first side surface, and a plurality of slots formed in the first facial surface,
wherein the carriage is configured to translate along a length of the first arm to engage a slot of a plurality of slots formed in the first facial surface when the location of the carriage is being locked, and
wherein a height of the first arm defined by the first side surface extending between the first and second facial surfaces is less than a width of the first arm defined by the first facial surface extending between the first and second side surfaces.

8. A method for drilling a bore in bone, comprising:
gripping a guide portion of a surgical guide system;
defining a location and trajectory for drilling of the bore with the guide portion;
locking a locking portion of the surgical guide system to set the trajectory of the bore, the locking portion being able to translate along the guide portion while the grip on the guide portion is maintained and does not move with respect to the guide portion during translation; and
drilling the bore with a drilling tool along the established trajectory.

9. The method of claim 8 , wherein locking the locking portion further comprises locking a carriage configured to slide along the guide portion with respect to the guide portion.

10. The method of claim 9 , wherein defining a location and trajectory for drilling of the bore further comprises:
moving the carriage along the guide portion; and
locking the carriage with respect to the guide portion.

11. The method of claim 10 , wherein moving the carriage along the guide portion further comprises moving the carriage between a plurality of designated trajectories designated on the guide portion that correlate to the trajectory of the bore.

12. The method of claim 10 , wherein the locking portion is configured such that it can be operated from either side of a patient by a user without moving components of the system to adapt it for use from a different side.

13. The method of claim 8 , wherein the carriage is configured such that it can be operated with either hand of a user without moving components of the system.

14. A method for drilling a tunnel in bone, comprising:
grasping a first arm of a ligament guide system in a palm of a hand, fingers of the hand being wrapped around the first arm;
positioning a second end of a second arm of the ligament guide system adjacent to a desired location for a distal end of a tunnel to be drilled in bone;
positioning a first end of the first arm of the ligament guide system proximate to an opposed side of the bone, the side at which a proximal end of the tunnel to be drilled in bone is to be located;
sliding a carriage disposed on the first arm along a length of the first arm and locking a location of the carriage with respect to the first arm to set a trajectory of the tunnel to be drilled in bone, wherein the carriage is able to be slid along the first arm while the hand grasping the first arm maintains the grasp such that the hand does not move with respect to the first arm; and
passing a drilling tool through an opening formed in the carriage to drill a tunnel in the bone from the side of the bone at which the first end of the first arm is located to the side of the bone at which the second end of the second arm is located,
wherein the second arm is devoid of a bore extending through a volume of the second arm such that the bore is fully enclosed by material that forms the second arm.

15. The method of claim 14 , further comprising:
positioning a bullet in the opening formed in the carriage; and
positioning a distal end of the bullet adjacent to a desired location for the proximal end of the tunnel to be drilled in bone,
wherein passing a drilling tool through an opening formed in the carriage includes passing the drilling tool through the bullet.

16. The method of claim 15 , further comprising:
disassociating the bullet from the first arm such that the ligament guide system is removed from the surgical site without removing the drilling tool from the bullet; and
passing the drilling tool from the distal end of the tunnel to the proximal end of the tunnel to expand a diameter of the tunnel.

17. The method of claim 14 , wherein the first arm has a plurality of slots formed therein and the carriage includes a passively engaging male member that is configured to engage a slot of the plurality of slots to lock a location of the carriage with respect to the first arm to set the trajectory of the tunnel to be drilled in bone.
