Abstract

A sterile suture anchor and insertion kit with the suture anchor having a cylindrical body portion with a generally tapered distal end portion and flat end. A plurality of parallel longitudinal grooves are cut into the cylindrical body and a connecting throughgoing bore is cut through the cylindrical body engaging the plurality of longitudinal grooves. An inserter driver is adapted to be mounted to the suture anchor, the driver comprising a handle with a drive shaft mounted to the handle, and a slidable sleeve mounted on the drive shaft which holds the suture anchor. A guide member comprising a handle with a hollow sleeve extending therefrom is used to hold a punch against the area on which a blind bore is formed to form the blind bore after which the inserter driver is mounted in the guide member sleeve to guide the slidable sleeve of the inserter driver and associated suture anchor into the blind bore.

Claims

1. A sterile suture anchor comprising:

a smooth surfaced substantially cylindrical body with a plurality of parallel longitudinal grooves cut into said cylindrical body;

a throughgoing bore is transversely cut through said cylindrical body with each end of said bore terminating in said longitudinal grooves, said longitudinal grooves and said throughgoing bore being dimensioned to hold at least one suture strand; and

said anchor having a flat proximal end and a cone shaped distal end.

2. A sterile suture anchor according to claim 1 wherein said flat proximal end defines a central blind bore dimensioned to receive the tip of an inserter driver.

3. A sterile suture anchor according to claim 1 wherein said cone shaped distal end terminates in a flat surface forming a truncated cone.

4. A sterile suture anchor according to claim 1 wherein said cone shaped end forms an angle ranging from 30°

to 45°

.

5. A sterile suture anchor as claimed in claim 1 wherein said suture anchor is constructed of allograft bone.

6. A sterile suture anchor as claimed in claim 1 wherein said suture anchor is constructed of xenograft bone.

7. A sterile suture anchor as claimed in claim 1 wherein said suture anchor is constructed of polymer.

8. A sterile suture anchor as claimed in claim 1 wherein said suture anchor is constructed of a bio-compatible metal.

9. A sterile biocompatible absorbable suture anchor comprising:

a substantially cylindrical body of allograft bone with a tapered distal end portion,

and a flat proximal end, said flat proximal end defining a centrally placed depression therein,

a plurality of parallel longitudinal grooves cut into said cylindrical body;

a throughgoing bore is positioned transverse to a central axis of said cylindrical body and opens into at least two of said longitudinal grooves.

10. A sterile suture anchor according to claim 9 wherein said cylindrical body tapered distal is a truncated cone having an angle ranging from 30°

to 45°

.

11. A sterile suture anchor as claimed in claim 9 wherein said allograft bone is human cortical bone.

12. A sterile suture anchor and insertion kit comprising:

a suture anchor having a substantially cylindrical body of allograft bone with a tapered distal end portion, and a flat proximal end, said flat proximal end defining a centrally placed depression therein,

a plurality of parallel longitudinal grooves cut into said cylindrical body;

a throughgoing bore is cut in said cylindrical body opening into said plurality of longitudinal grooves; and

a inserter driver adapted to be mounted to said suture anchor, said inserter driver comprising a handle and a shaft mounted to said handle, said shaft being provided a slideable sleeve member adapted to be inserted over said suture anchor.

13. A sterile suture anchor and inserter kit as claimed in claim 12 wherein said inserter driver handle defines a suture holding recess.

14. A sterile suture anchor and inserter kit as claimed in claim 12 wherein said inserter driver handle defines a suture guide channel.

15. A sterile suture anchor and inserter kit as claimed in claim 12 wherein said inserter kit includes a guide member, said guide member comprising a handle and a guide sleeve mounted to said handle.

16. A sterile suture anchor and inserter kit as claimed in claim 15 wherein said guide sleeve is provided with at least one slit running longitudinally along the guide sleeve.

17. A sterile suture anchor and inserter kit as claimed in claim 15 wherein said guide sleeve defines a “

V”

shaped distal tip.

18. A sterile suture anchor and inserter kit as claimed in claim 15 wherein said handle is angled from a central axis of said guide sleeve.

19. A sterile suture anchor and inserter kit as claimed in claim 15 wherein said kit further includes a punch driver.

20. A sterile suture anchor and inserter kit as claimed in claim 19 wherein said punch driver comprises a steel cylindrical shaft with a triangular shaped tip.
