Abstract

An arthroscopic bone channel forming and suturing method including forming a first generally straight channel in a bone, forming a second generally straight channel in the bone, the second generally straight channel not intersecting the first generally straight channel, inserting a curved needle into the first generally straight channel, inserting a suture through the second generally straight channel in the bone to a suture pick-up location, manipulating the curved needle to form a curved junction between the first generally straight channel and the second generally straight channel; and pulling the suture by the curved needle from the suture pick-up location through the junction and though the first generally straight channel.

Claims

1. An arthroscopic bone channel forming and suturing method comprising:

forming a first generally straight channel in a bone;

inserting a curved needle into said first generally straight channel;

forming a second generally straight channel in said bone, said second generally straight channel not intersecting said first generally straight channel;

inserting a suture through said second generally straight channel in said bone to a suture pick-up location;

manipulating said curved needle to form a curved junction between said first generally straight channel and said second generally straight channel; and

pulling said suture by said curved needle from said suture pick-up location through said junction and though said first generally straight channel.

2. An arthroscopic bone channel forming and suturing method according to claim 1 and wherein said inserting said suture comprises locating a folded over end of said suture at said suture pick-up location.

3. An arthroscopic bone channel forming and suturing method according to claim 1 and wherein free ends of said suture extend outside of said second channel.

4. An arthroscopic bone channel forming and suturing method according to claim 1 and wherein said second generally straight channel is substantially longer than said first generally straight channel.

5. An arthroscopic bone channel forming and suturing method according to claim 1 and wherein said curved needle has a radius of curvature which is generally equal to or greater than a length of said first generally straight channel.

6. An arthroscopic bone channel forming and suturing method according to claim 1 and wherein the geometry of said curved needle and the geometry of said first generally straight channel are such that said curved needle can pass through said first generally straight channel without changing the configuration of said first generally straight channel to add curvature thereto.

7. An arthroscopic bone channel forming and suturing method according to claim 6 and wherein said geometry of said curved needle includes its width and its inner and outer radii of curvature and wherein said geometry of said first generally straight channel includes its width and its length.

8. An arthroscopic bone channel forming and suturing system comprising:

a punch configured to form a first generally straight channel in a bone;

a drill configured to form a second generally straight channel in said bone, said second generally straight channel not intersecting said first generally straight channel;

a curved needle configured to be insertable into said first generally straight channel;

a needle driving assembly configured to manipulate said curved needle to form a curved junction between said first generally straight channel and said second generally straight channel; and

a suture assembly configured to insert a suture to a suture pick-up location via said second generally straight channel in said bone,

said curved needle being configured to pull said suture from said suture pick up location and through said junction and said first generally straight channel.

9. An arthroscopic bone channel forming and suturing system according to claim 8 and wherein said curved needle has a radius of curvature which is generally equal to or greater than a length of said first generally straight channel.

10. An arthroscopic bone channel forming and suturing method comprising:

forming a first channel in a bone;

inserting a curved needle into said first channel;

forming a second channel in said bone by using a straight drill extending through a straight working channel;

removing said drill from said working channel;

inserting a suture through said working channel extending through said second channel in said bone to a suture pick-up location; and

pulling said suture by said curved needle from said suture pick-up location though said first channel.

11. An arthroscopic bone channel forming and suturing method according to claim 10 and also comprising forming a single incision in a patient'"'"'s body for insertion and removal of said curved needle and said drill.

12. An arthroscopic bone channel forming and suturing method according to claim 11 and wherein:

said inserting a suture comprises locating a folded over portion of said suture at said suture pick-up location; and

free ends of said suture remain outside of said incision.

13. An arthroscopic bone channel forming and suturing method according to claim 10 and wherein said second channel is substantially longer than said first channel.

14. An arthroscopic bone channel forming and suturing method according to claim 10 and wherein said curved needle has a radius of curvature which is generally equal to or greater than a length of said first channel.

15. An arthroscopic bone channel forming and suturing method according to claim 10 and wherein the geometry of said curved needle and the geometry of said first channel are such that said curved needle can pass through said first channel without changing the configuration of said first channel to add curvature thereto.

16. An arthroscopic bone channel forming and suturing method according to claim 15 and wherein said geometry of said curved needle includes its width and its inner and outer radii of curvature and wherein said geometry of said first channel includes its width and its length.

17. An arthroscopic bone channeling and suturing system comprising:

a punch configured to form a first channel in a bone;

a straight drill extending through a straight working channel and being adapted to form a second channel and to insert said working channel in said straight channel in said bone;

a needle driving assembly configured to insert a tunneling needle into said first channel; and

a suture assembly configured to insert a suture through said working channel and through said second channel in said bone to a suture pick-up location,

said needle driving assembly being configured to retract said tunneling needle together with said suture from said suture pick-up location though said first channel.

18. An arthroscopic bone channeling and suturing system according to claim 17 and wherein said drill is removable from said working channel to allow insertion of said suture assembly into said working channel.

19. An arthroscopic bone channeling and suturing system according to claim 17 and wherein said drill is formed with a drill bit configuration at a forward end thereof.

20. An arthroscopic bone channeling and suturing system according to claim 17 and wherein said suture assembly comprises:

a pair of forward arms; and

said suture looped over said pair of forward arms.

21. An arthroscopic bone channeling and suturing system according to claim 17 and wherein said needle driving assembly is configured to drive said tunneling needle through said bone from said first channel to said suture pick-up location.

22. An arthroscopic bone channeling and suturing system according to claim 17 and wherein said tunneling needle includes a suture engagement groove configured to retain said suture and pull said suture from said suture pick-up location through said first channel.
