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 surgical instrument, comprising:
a guide arm having a first portion configured to define an angle at which a bore is to be drilled into bone and a second portion configured to define a location of a distal end of the bore to be drilled into bone, the distal end of the bore to be drilled into bone corresponding to an exit face of the bore to be drilled into bone, wherein an angle extending between the first portion and the second portion is approximately 110 degrees or less; and
a carriage disposed on the first portion of the guide arm, the carriage having a length that is greater than a width or a thickness thereof, and the length of the carriage extending substantially transverse to a length of the first portion of the guide arm, and the carriage being configured to translate along a length of the first portion and to be selectively locked at different locations along the length to set the angle at which the bore is to be drilled into bone.

2. The surgical instrument of claim 1 , wherein the carriage includes a bullet-receiving opening formed therein that is configured to receive a bullet.

3. The surgical instrument of claim 2 , further comprising a bullet configured to be removably coupled to the carriage and, when coupled to the carriage, configured to define a location of a proximal end of the bore to be drilled into bone.

4. The surgical instrument of claim 2 ,
wherein the first portion of the guide arm includes opposed first and second flat surfaces and first and second sidewalls extending between the first and second flat surfaces, the surface areas of the flat surfaces being substantially larger than the surface areas of the sidewalls,
wherein the carriage includes first and second opposed facial surfaces and first and second side surfaces extending between the first and second facial surfaces, the first and second flat surfaces of the first portion of the guide arm and the first and second facial surfaces of the carriage extending substantially parallel to each other, with the first facial surface of the carriage facing away from the first flat surface of the first portion of the guide arm,
wherein the bullet-receiving opening is formed in the first facial surface of the carriage.

5. The surgical instrument of claim 4 , wherein the carriage is configured such that a bullet received by the bullet-receiving opening is held at an angle with respect to the second flat surface such that a distal tip of a drill pin extending through the bullet disposed in the bullet receiving opening is configured to engage a distal end of the second portion of the guide arm that defines the location of the distal end of the bore to be drilled into bone.

6. The surgical instrument of claim 1 , wherein the first portion is not movable with respect to the second portion when the first and second portions are coupled together.

7. The surgical instrument of claim 1 , wherein the first portion of the guide arm includes a plurality of slots formed therein, each slot being indicative of an intended angle at which the bore is to be drilled into bone.

8. The surgical instrument of claim 7 , wherein the carriage includes a passive locking mechanism configured to passively engage a slot of the plurality of slots to set the angle at which the bore is to be drilled into bone.

9. The surgical instrument of claim 8 , wherein the passive locking mechanism comprises a selectively deployable key having a configuration that is complementary to the plurality of slots such that when the selectively deployable key is disposed in a slot, the location of the carriage is fixed with respect to the first portion of the guide arm.

10. The surgical instrument of claim 9 , wherein the passive locking mechanism further comprises a button configured to disengage the selectively deployable key from a slot of the plurality of slots to allow the carriage to translate along a length of the first portion.

11. The surgical instrument of claim 1 , wherein the second portion includes a distal tip disposed at a terminal end thereof, the tip being configured to engage bone at an intended location of the distal end of the bore to be drilled into bone.

12. A surgical guide for use in conjunction with drilling a bore in bone, comprising:
a first arcuate arm having a first end, a second end, and an intermediate portion extending therebetween, the intermediate portion having indicia formed thereon to indicate an intended angle at which a bore is to be drilled into bone;
a second arm having a first end, a second end, and an intermediate portion extending therebetween, the first end of the second arm being directly connected to the second end of the first arm to form a unitary construction of the guide such that the second arm is substantially stationary with respect to the first arm, and an angle extending between the first and second arms is approximately 110 degrees or less; and
a bullet configured to be removably associated with the first arcuate arm such that a location of the bullet with respect to the indicia reflects an intended angle at which a distal tip of the bullet is to form with the bone in which the bore is to be drilled, and in turn defining the intended angle of the bore to be drilled into the bone,
wherein the first arm and the second arm are not moved with respect to one another to adjust the intended angle of the bore to be drilled into the bone.

13. The guide of claim 12 , wherein the indicia further comprise a plurality of engagement features formed in a surface of the first arcuate arm.

14. The guide of claim 12 , wherein the second end of the second arm includes a distal tip configured to engage bone at an intended location of a distal end of the bore to be drilled into the bone.

15. The guide of claim 12 , wherein the first arm includes opposed first and second flat surfaces and first and second sidewalls extending between the first and second flat surfaces, the surface areas of the flat surfaces being substantially larger than the surface areas of the sidewalls.

16. The guide of claim 12 , further comprising a carriage configured to receive the bullet, translate along a length of the first arm, and be selectively locked with respect to the indicia to set the intended angle at which the distal tip of the bullet is intended to form with the bone in which the bore is being drilled.

17. The guide of claim 16 , wherein the carriage includes first and second opposed facial surfaces and first and second side surfaces extending between the first and second facial surfaces, the first facial surface of the carriage facing away from the first arcuate arm.

18. The guide of claim 17 , wherein the carriage is configured such that the bullet received by the carriage is held at an angle with respect to the first arcuate arm such that a distal tip of a drill pin extending through the bullet is configured to engage a distal tip of the second arm.

19. The guide of claim 16 ,
wherein the indicia further comprise a plurality of slots formed in a surface of the first arcuate arm, and
wherein the carriage includes a passive locking mechanism configured to passively engage a slot of the plurality of slots to set the intended angle of the bore to be drilled into the bone.

20. A surgical instrument, comprising:
a guide arm having a first portion configured to define an angle at which a bore is to be drilled into bone and a second portion having a distal tip disposed at a terminal end thereof, the distal tip configured to be positioned at a location of a d
