Self-drilling anchor inserter
An anchor inserter including an inserter tube extending along a longitudinal axis having a proximal inserter end and a distal inserter end. The inserter also includes an inserter tip attached to and extending distally from the distal inserter end. The inserter tip has a proximal tip end and a distal tip end with a suture anchor retention slot extending through the distal tip end. The inserter has one or more cutting edges extending at least a partially along an outer perimeter edge of the distal tip end. The distal tip end has a first arm and a second arm. The first arm is substantially straight and the second arm is curved.
1. An anchor inserter, comprising
a cannulated inserter tube extending along a longitudinal axis having a proximal inserter end and distal inserter end;
a cannulated suture tube extending through the cannulated inserter tube, the cannulated suture tube having a proximal suture tube and a distal suture tube end;
an inserter tip attached to and extending distally from the distal inserter end, the inserter tip having a proximal tip end and a distal tip end;
a suture anchor retention slot extending through the distal tip end, wherein the suture anchor retention slot comprises a straight portion connected to a curved portion that extends at an angle from the straight portion; and
one or more features on the proximal tip end removably connected to one or more features on the distal inserter end.
2. The anchor inserter of claim 1 , wherein the proximal tip end comprises a proximal tip tube and the distal suture tube end extends at least partially into the proximal tip tube.
3. The anchor inserter of claim 1 , wherein one or more features on the proximal tip end are protrusions and the one or more features on the distal inserter end are slots.
4. The anchor inserter of claim 1 , wherein the cannulated suture tube is substantially co-linear with the longitudinal axis.
5. The anchor inserter of claim 1 , further comprising a quick change connector attached to and extending proximally from the proximal inserter end.
6. The anchor inserter of claim 5 , wherein the quick change connector is an AO compatible quick chance connector.
7. An anchor inserter system, comprising:
a cannulated inserter tube extending along a longitudinal axis having a proximal inserter end and distal inserter end;
a cannulated suture tube extending through the cannulated inserter tube, the cannulated suture tube having a proximal suture tube end and a distal suture tube end;
an inserter tip attached to and extending distally from the distal inserter end;
a suture anchor retention slot extending through the inserter tip, wherein the suture anchor retention slot comprises a straight portion connected to a curved portion that extends at an angle from the straight portion; and
an anchor with a length of suture positioned therethrough extending through the suture anchor retention slot, such that the length of suture extends proximally along the inserter tip.
8. The system of claim 7 , wherein the anchor is an anchor braid with the length of suture positioned through one surface of the anchor braid.
9. The system of claim 7 , further comprising a plurality of passing locations along the anchor, wherein the length of suture is woven through the anchor at the plurality of passing locations.
10. The system of claim 7 , wherein the length of suture extends into the distal suture tube end of the cannulated suture tube.
11. The system of claim 7 , wherein the length of suture extends out from the cannulated suture tube at the proximal suture tube end and extends distally along an outer surface of the cannulated suture tube.
12. The system of claim 11 , wherein the length of suture extends within an annular space between the cannulated suture tube and the cannulated inserter tube.
