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. An instrument with a proximal end and a distal end, the instrument configured to manipulate soft tissue during a soft tissue repair procedure, the instrument comprising:
a cannulated instrument body;
a first prong coupled to the cannulated instrument body, wherein the first prong is a most distal element of the instrument and is offset from a cross-sectional center of the cannulated instrument body; and
markings on the instrument representing a measured distance from a distal end of the first prong to the markings.

2. The instrument of claim 1 wherein the cannulated instrument body includes a handle at its proximal end.

3. The instrument of claim 1 wherein the cannulated instrument body includes a shaft near its distal end.

4. The instrument of claim 1 , further comprising a second prong coupled to the cannulated instrument body opposite from the first prong to form a channel between the first prong and the second prong, wherein the channel aligns at least in part with a cannulation of the cannulated instrument body.

5. The instrument of claim 4 wherein the second prong is substantially a mirror image of the first prong about a longitudinal axis of the cannulated instrument body.

6. The instrument of claim 4 wherein a diameter of the prongs is larger than a diameter of the instrument proximal of the prongs.

7. The instrument of claim 4 wherein there are markings on the instrument representing a measured distance from a distal end of the second prong to the markings.

8. The instrument of claim 4 wherein the first and second prongs have respective first axes parallel with a longitudinal axis of the cannulated instrument body, and the first and second prongs are generally rectangular in cross-section transverse to their respective first axes, and each of the first and second prongs has a longer length side of its respective rectangular cross-section that is oriented generally perpendicularly to the longitudinal axis of the cannulated instrument body.

9. An instrument with a proximal end and a distal end, the instrument configured to manipulate soft tissue during a soft tissue repair procedure, the instrument comprising:
a cannulated instrument body;
a first prong coupled to the cannulated instrument body, wherein the first prong is a most distal element of the instrument and is offset from a cross-sectional center of the cannulated instrument body;
a second prong coupled to the cannulated instrument body opposite from the first prong to form a channel between the first prong and the second prong, wherein the channel aligns at least in part with a cannulation of the cannulated instrument body; and
markings on the instrument representing a measured distance from a distal end of the first prong to the markings;
wherein the first prong and the second prong are rounded and blunted at their respective distal ends to not readily penetrate bone when pushed against the bone.

10. The instrument of claim 9 wherein the cannulated instrument body includes a handle at its proximal end.

11. The instrument of claim 9 wherein the cannulated instrument body includes a shaft near its distal end.

12. The instrument of claim 11 wherein a diameter of the prongs is larger than a diameter of the shaft proximal of the prongs.

13. The instrument of claim 9 wherein the second prong is substantially a mirror image of the first prong about a longitudinal axis of the cannulated instrument body.

14. An instrument with a proximal end and a distal end, the instrument configured to manipulate soft tissue during a soft tissue repair procedure, the instrument comprising:
a cannulated instrument body;
a fork means at a distal end of the instrument for capturing soft tissue between a first prong of the fork and a second prong of the fork and aligning the soft tissue with a cannulation of the cannulated instrument body; and
a depth determining means for measuring a distance from a distal end of the fork means to markings on the instrument.

15. The instrument of claim 14 wherein the cannulated instrument body includes a handle at its proximal end.

16. The instrument of claim 14 wherein the cannulated instrument body includes a shaft near its distal end.

17. The instrument of claim 16 wherein an outer diameter of the fork means is larger than the shaft proximal of the fork means.

18. The instrument of claim 14 wherein a channel is formed between the first prong of the fork and the second prong of the fork and the channel is substantially coaxially aligned with the cannulation of the cannulated instrument body.

19. An instrument with a proximal end and a distal end, the instrument configured to manipulate soft tissue during a soft tissue repair procedure, the instrument comprising:
a cannulated instrument body;
a first prong coupled to the cannulated instrument body, wherein the first prong is a most distal element of the instrument and is offset from a cross-sectional center of the cannulated instrument body;
a second prong coupled to the cannulated instrument body opposite from the first prong to form a channel between the first prong and the second prong, wherein the channel aligns at least in part with a cannulation of the cannulated instrument body; and
markings on the instrument representing a measured distance from a distal end of the second prong to the markings;
wherein the first prong and the second prong are rounded and blunted at their respective distal ends to not readily penetrate bone when pushed against the bone.

20. The instrument of claim 19 wherein the cannulated instrument body includes a handle at its proximal end.

21. The instrument of claim 19 wherein the cannulated instrument body includes a shaft near its distal end.

22. The instrument of claim 21 wherein a diameter of the prongs is larger than a diameter of the shaft proximal of the prongs.

23. The instrument of claim 19 wherein the second prong is substantially a mirror image of the first prong about a longitudinal axis of the cannulated instrument body.
