Abstract

The present disclosure relates to an instrument and method of manipulating soft tissue during a soft tissue repair procedure. The instrument and related method may include use of a handle and a shaft coupled to the handle, the shaft including a proximal portion and a distal portion, wherein the distal portion of the shaft comprises a tip including at least two prongs and a channel located between the prongs.

First claim

What is claimed is:

1. A method of tissue repair comprising:
creating a hole in bone;
placing soft tissue over the hole;
providing an instrument for inserting the soft tissue into the hole, the instrument including a shaft comprising a proximal portion and a distal portion, wherein the distal portion comprises a tip including at least two prongs and a channel located between the prongs;
inserting the soft tissue into the hole via use of the instrument, wherein the soft tissue is housed within the channel; and
inserting a fixation device into the hole to fix the soft tissue to the bone.

2. The method of claim 1 wherein the act of providing an instrument includes providing a cannulated instrument.

3. The method of claim 2 , further comprising inserting a guide assembly through the cannulation of the instrument and into the bone prior to inserting the fixation device into the hole, the guide assembly comprising a guide wire and a vice coupled to the guide wire, the guide assembly inserted through the cannulation until a bottom portion of the vice engages with a handle of the instrument.

4. The method of claim 3 , further comprising inserting the fixation device into the hole via use of the guide wire.

5. The method of claim 1 wherein the act of providing an instrument includes providing an instrument with a tip outer diameter that is between about 4.5 mm to about 5.5 mm.

6. A method of attaching a biceps tendon to a humerus comprising:
creating a hole in the humerus of a first diameter;
pushing a portion of a biceps tendon into the hole with an instrument that captures the biceps tendon at a distal end of the instrument;
inserting a distal portion of a guide wire though the biceps tendon and into the hole in the humerus; and
inserting a fixation device over the guide wire to fix the biceps tendon to the humerus.

7. The method of claim 6 wherein the act of creating a hole includes inserting a drill bit into the humerus.

8. The method of claim 7 wherein the act of creating a hole includes disposing a cannulated reamer over the drill bit and creating the hole of the first diameter.

9. The method of claim 6 wherein the act of pushing a portion of the biceps tendon into the hole with an instrument that captures the biceps tendon at a distal end of the instrument includes capturing the biceps tendon in a channel adjacent to one or more prongs of a tip at the distal end of the instrument.

10. The method of claim 9 wherein the channel adjacent to the one or more prongs of the tip is larger in a longitudinal direction of the instrument than the diameter of the biceps tendon being captured.

11. The method of claim 6 wherein the act of inserting the distal portion of the guide wire though the biceps tendon and into the hole in the humerus includes inserting the distal portion of the guide wire though a cannulation in the instrument along a longitudinal length of the instrument.

12. The method of claim 6 wherein the act of inserting the distal portion of the guide wire though the biceps tendon and into the hole in the humerus includes placing a vice at a proximal end of the guide wire and impacting a proximal end of the vice, wherein a distal portion of the vice contacts a proximal end of the instrument to limit penetration of the guide wire into the humerus.

13. The method of claim 6 wherein the act of inserting a fixation device includes inserting an interference screw.

14. The method of claim 13 wherein the act of inserting an interference screw includes inserting an interference screw sized such that a threaded outer surface of the interference screw is engaged with the biceps tendon on one or more sides of the interference screw to fix the biceps tendon to the humerus when the interference screw is within the hole in the humerus.

15. The method of claim 6 , further comprising rotating a driver that fits over the guide wire and engages with the fixation device to insert the fixation device and fix the biceps tendon to the humerus.

16. The method of claim 6 , further comprising removing the guide wire from the humerus through the fixation device.

17. A method of tissue repair comprising:
creating a hole in a bone of a first diameter;
pushing a portion of soft tissue into the hole with an instrument that captures the soft tissue in a channel adjacent to one or more prongs of a tip at a distal end of the instrument;
inserting a distal portion of a guide wire though the soft tissue and in the hole in the bone; and
inserting a fixation device over the guide wire to fix the soft tissue to the bone.

18. The method of claim 17 wherein the channel adjacent to the one or more prongs of the tip is larger in a longitudinal direction of the instrument than the diameter of the soft tissue being captured in the channel.

19. The method of claim 17 wherein the act of inserting the distal portion of the guide wire though the soft tissue and iii the hole in the bone includes inserting the distal portion of the guide wire though a cannulation in the instrument along a longitudinal length of the instrument.

20. The method of claim 17 wherein the act of inserting a fixation device includes inserting an interference screw.

21. The method of claim 7 , further comprising rotating a driver that fits over the guide wire and engages with the fixation device to insert the fixation device to fix the soft tissue to the bone.
