Abstract
An anchoring system implantable in bone. The anchoring system includes a screw having a screw head, a screw shaft, a plurality of interface elements, each adjacent pair of the interface elements has an interface by-pass channel disposed therebetween, a boring ring that includes cutting teeth and a ring by-pass channel, and a coupling assembly that is adjustable with respect to a longitudinal axis of the screw.
Claims18
An anchoring system comprising:
- a screw system comprising:
- a screw including a screw head, a screw shaft and a plurality of interface elements, each pair of the interface elements having an interface by-pass channel located therebetween;
- a boring ring including an upper surface, a lower surface, a wall portion extending between the upper surface and the lower surface, and a plurality of cutting teeth along the wall portion extending longitudinally from the upper surface to the lower surface;
- and
- a coupling assembly that is adjustable with respect to a longitudinal axis of the screw, the coupling assembly being adapted to attach to the screw head;
- and
- a driver comprising a handle, a driver shaft, and a driver head having a cavity configured to receive the coupling assembly and the boring ring,
- wherein the driver head includes teeth at its distal end configured to cut into tissue and bone.
