Abstract

A fixation suture device (12) wherein an anchor (1) has a top (6), a core (2) and a tip (5) and external threads (4) located on the anchor core (2). An anchor aperture (3) is located on the anchor (1) for acceptance of sutures (13). To use the device (12), a surgeon passes the sutures (13) through a rotator cuff tendon (14). Then, the sutures (13) are passed through the anchor aperture (3) and the anchor tip (5) is positioned against a humerus (21) via a handle (22) and cannula (23). The surgeon pushes downward on the handle (22) to provide a downward force on the anchor (1) while pulling upward on the sutures (13) in order to produce a desired tension on the rotator cuff tendon (14). The surgeon rotates the anchor (1) into the humerus (21) while maintaining tension on the sutures (13). As the anchor (1) is rotated deeper and deeper into the humerus (21), the sutures (13) secured to the rotator cuff tendon (14) wind around the anchor core (2), thereby pulling the rotator cuff tendon (14) closer and closer to the anchor (1). When the anchor top (6) is in alignment with or located below the humerus (21), the sutures (13) wrap around the sutures (13) held by the surgeon to create a wrap (24).

Claims

1. A fixation suture device comprising:

an anchor having a top, core and tip;

at least one anchor external thread located on said anchor core;

at least one anchor aperture located on said anchor; and

at least one suture for threading into said at least one anchor aperture wherein said at least one suture winds around said at least one anchor external thread when said anchor is rotated.

2. The fixation suture device of claim 1 wherein:

said at least one anchor aperture is located on said anchor tip.

3. The fixation suture device of claim 1 wherein:

said at least one anchor aperture is located on said anchor core.

4. The fixation suture device of claim 2 further comprising:

at least one anchor aperture located on said anchor core.

5. The fixation suture device of claim 1 wherein:

said at least one anchor aperture is round.

6. The fixation suture device of claim 1 wherein:

said at least one anchor aperture is oval.

7. The fixation suture device of claim 1 wherein:

said at least one anchor aperture is triangular.

8. The fixation suture device of claim 1 wherein:

said anchor core is roughened.

9. The fixation suture device of claim 1 wherein:

said anchor tip is pointed.

10. The fixation suture device of claim 1 wherein:

said anchor tip is rounded.

11. The fixation suture device of claim 1 further comprising:

a female head located on said anchor top.

12. The fixation suture device of claim 1 further comprising:

a male head located on said anchor top.

18. The fixation suture device of claim 1 further comprising:

a substantially conically-shaped retaining cone having an exterior and interior surface;

a rim of a predetermined shape located on said retaining cone;

at least one external thread located on said retaining cone exterior surface;

an anchor opening centrally located within said retaining cone;

at least one rim opening located on said rim wherein said rim opening provides access to said anchor opening; and

at least one internal thread located on said retaining cone interior surface and encircling said anchor opening wherein said at least one external thread on said anchor body corresponds with said at least one internal thread located on said retaining cone interior surface to lock said anchor into said retaining cone when said anchor is rotated within said retaining cone.

13. A fixation suture device comprising:

an anchor having a top, core and tip;

at least one anchor external thread located on said anchor core;

at least one notch located on said anchor; and

at least one suture for threading into said at least one notch wherein said at least one suture winds around said at least one anchor external thread when said anchor is rotated.

14. The fixation suture device of claim 13 wherein:

said at least one notch is located on said anchor tip.

15. The fixation suture device of claim 13 wherein:

said at least one notch is located on said anchor core.

16. The fixation suture device of claim 14 further comprising:

at least one notch located on said anchor core.

17. The fixation suture device of claim 13 wherein:

said anchor core is roughened.

19. The fixation suture device of claim 13 further comprising:

a substantially conically-shaped retaining cone having an exterior and interior surface;

a rim of a predetermined shape located on said retaining cone;

at least one external thread located on said retaining cone exterior surface;

an anchor opening centrally located within said retaining cone;

at least one rim opening located on said rim wherein said rim opening provides access to said anchor opening; and

at least one internal thread located on said retaining cone interior surface and encircling said anchor opening wherein said at least one external thread on said anchor body corresponds with said at least one internal thread located on said retaining cone interior surface to lock said anchor into said retaining cone when said anchor is rotated within said retaining cone.

20. A method for using a fixation suture device comprising an anchor having a top, core and tip;

at least one anchor external thread located on said anchor core;

at least one anchor aperture located on said anchor; and

at least one suture for threading into said at least one anchor aperture wherein said at least one suture winds around said at least one anchor external thread when said anchor is rotated, said method comprising steps of;

a. passing said at least one suture through a rotator cuff tendon;

b. passing said at least one suture through said at least one aperture;

c. pulling upward on said at least one suture in order to produce a desired tension on said rotator cuff tendon; and

d. rotating said anchor into a humerus such that said at least one suture forms a wrap.

21. The method of claim 20 further comprising a step after step d of:

e. cutting said at least one suture.
