Abstract

The device (10) has a handle assembly (40) and a bone anchor driver assembly (20). The handle assembly (40) has an upper handle portion (50) and a lower handle portion (60) as illustrated. The upper or lower handle portion is rotatable relative to the other handle portion. A bone anchor driver assembly (20) is for rotatably driving a bone anchor (12) into a hole in a bone is provided. The bone anchor driver assembly (20) is fixed to one of either the upper or lower handle portions (50 or 60).

Claims

7. A bone anchor delivery system device comprises:

a handle assembly having an upper handle portion and a lower handle portion, the upper and lower handle portions being rotatable relative to the other;

a bone anchor driver assembly for rotatable driving a bone anchor, the bone anchor driver assembly being fixed to one of said upper or lower handle portions; and

wherein the handle assembly rotation of the handle portion fixed to the driver allows the other handle portion to be held non-rotatably for stabilization of the device.

8. The bone anchor delivery system device of claim 7 wherein the upper handle portion is fixed to the driver assembly.

9. The bone anchor delivery system device of claim 7 wherein the upper handle portion has an impact end for receiving blows from a mallet and the driver assembly has a leading end having a removable bone anchor with a punch tip attached for penetrating bone to form an anchor opening.

10. The bone anchor delivery system device of claim 9 wherein the bone anchor is releasable relative to the driver assembly.

11. The bone anchor delivery system device of claim 10 wherein the bone anchor driver assembly further non-rotatably holds the bone anchor, said bone anchor being releasably held on said driver assembly, and wherein after being driven into said anchor opening, the driver assembly is withdrawn releasing said bone anchor fixed to said bone opening.

12. The bone anchor delivery system device of claim 11 wherein the bone anchor has threads and is rotatably driven into the bone opening.

13. The bone anchor delivery system device of claim 12 wherein the bone anchor driver assembly includes an elongated drive shaft fixed to the handle, the drive shaft having a hollow stem extending from the handle to the leading end.

14. The bone anchor delivery system device of claim 13 wherein the bone anchor driver assembly drive shaft has the leading end with a tip portion extending from the leading end, the tip portion having a pair of openings for receiving sutures and at least one flat surface extending along the tip lengthwise to rotationally fix the bone anchor to the drive shaft.

15. The bone anchor delivery system device of claim 14 wherein the bone anchor has a hollow end for attachment removably attached on said tip portion, the bone anchor having at least one pair of suture openings, each pair of suture openings being within a thread channel formed by two adjacent threads, each of the two openings of a pair being within 90 degrees of the other and extending into the hollow end opening.

16. The bone anchor delivery system device of claim 15 further comprises a suture threaded and looped through the at least one pair of suture openings, the suture extending from the bone anchor through one of the tip openings internally through the hollow stem.

17-1. The bone anchor delivery system device of claim 1 wherein the bone anchor has two or more pairs of suture openings, each opening of one pair being radially aligned with an opening of another pair.

18-2. The bone anchor delivery system device of claim 1 wherein the bone anchor has two or more pairs of suture openings, each opening of one pair being radially offset relative to the openings of another pair.

19-3. The bone anchor delivery system device of claim 1 wherein the bone anchor has two or more pairs of suture openings, each opening of one pair being linearly aligned with an opening of another pair.

20-4. The bone anchor delivery system device of claim 1 wherein the bone anchor has two or more pairs of suture openings, each opening of one pair being linearly offset relative to the openings of another pair.
