Abstract

The present invention relates to a threaded suture anchor for use in securing tissue to bone. The present invention further relates to the combination of a suture anchor and a suture without the need to tie a knot in the suture.

Claims

1. A suture anchor comprising:

a. an outer conical member comprising a first end region comprising a top annular surface having an inner diameter and an outer diameter, a second end region opposite said first end region, threads mounted on said conical member, and a central channel extending longitudinally through the entire length of said conical member; and

b. an anchoring member rotatably attached in said central channel, said anchoring member having an upper end region extending out of said channel, said upper end region comprising a suture securing receptacle, and said anchoring member having a pointed lower end region opposite said upper end region and extending beyond the second end region of said outer conical member.

2. The suture anchor of claim 1, wherein said suture securing receptacle is a hook.

3. The suture anchor of claim 2, wherein said hook has a diameter that is less than the outer diameter of said top annular surface.

4. The suture anchor of claim 2 further comprising a suture loop attached to said hook.

5. The suture anchor of claim 1, wherein said suture securing receptacle is an eyelet.

6. The suture anchor of claim 5, further comprising a suture loop extending through said eyelet.

7. The suture anchor of claim 1, wherein said top annular surface is hexagonal.

8. The suture anchor of claim 1, wherein said top annular surface comprises a first groove extending across the diameter of said top annular surface.

9. The suture anchor of claim 8, further comprising a second groove extending across the diameter of said top annular surface and oriented perpendicular to said first groove.

10. The suture anchor of claim 1, wherein said threads are large enough to purchase cancellous bone.

11. The suture anchor of claim 1, wherein threads are mounted on said lower end region.

12. A suture anchor comprising:

a. an outer conical member comprising a first end region comprising a top annular surface having an inner diameter and an outer diameter, a second end region opposite said first end region, threads mounted on said conical member, and a central channel extending longitudinally through the entire length of said conical member;

b. an anchoring member rotatably attached in said central channel, said anchoring member having an upper end region extending out of said channel, said upper end region comprising a suture securing receptacle, and said anchoring member having a pointed lower end region opposite said upper end region and extending beyond the second end region of said outer conical member; and

c. a suture loop attached to said suture securing receptacle.

13. The suture anchor of claim 12, wherein said suture securing receptacle is an eyelet.

14. The suture anchor of claim 13, wherein said top annular surface is hexagonal.

15. The suture anchor of claim 14, wherein said top annular surface comprises a first groove extending across the diameter of said top annular surface.

16. The suture anchor of claim 15, wherein said threads are large enough to purchase cancellous bone.

17. The suture anchor of claim 12, wherein threads are mounted on said lower end region.

18. A suture anchor comprising:

a. an outer conical member comprising a first end region comprising a top annular surface having an inner diameter and an outer diameter, a second end region opposite said first end region, threads mounted on said conical member, and a central channel extending longitudinally through the entire length of said conical member; and

b. an anchoring member rotatably mounted in said central channel, said anchoring member having an upper end region comprising a suture securing receptacle, and said anchoring member having a pointed lower end region opposite said upper end region and extending beyond the second end region of said outer conical member.

19. The suture anchor of claim 18, wherein said top annular surface comprises a first groove extending across the diameter of said top annular surface.
