Abstract

An implant kit has an adapter having a first end, a second end, and a longitudinal axis extending from the first and to the second end, wherein the first end is configured for removably receiving and engaging an implant and the second end is configured for removably coupling to a driver shaft of an implant driving tool, and an implant preloaded into the first end of the adapter, the implant having an elongated threaded portion; and a blade portion extending from the elongated threaded portion, and having two serrated edges, wherein the blade portion is received in the first end of the adapter and the elongated threaded portion of the implant is coaxially aligned with the longitudinal axis of the adapter.

Claims (30)

1. An adapter for retaining an implant, the adapter comprising:

a first end, a second end, and a longitudinal axis extending from the first end to the second end, wherein the first end is configured for removably receiving and engaging the implant and the second end includes a retaining nut that is rotatable about the longitudinal axis, the retaining nut having a threaded bore extending along the longitudinal axis so as to be configured for coupling to a driver shaft of an implant driving tool and wherein the first end comprises:

an adapter body having a first end and a second end;

a slot provided within the adapter body, extending longitudinally therein and open at the first end of the adapter body; and

a bifurcated clip having a stem portion with a screw threaded portion that extends through the threaded bore of the retaining nut and a pair of bifurcated arms received within the slot wherein the stem portion extends through the second end of the adapter body and the bifurcated clip is slidable within the slot between an extended position and a retracted position whereby the bifurcated clip is moved between the extended position and the retracted position by rotating the retaining nut; and

wherein when the bifurcated clip is in the retracted position the bifurcated arms are in a closed position and the implant is retained between the pair of bifurcated arms.

2. The adapter of claim 1 , wherein the bifurcated clip is spring-biased for keeping the bifurcated clip in the retracted position.

3. The adapter of claim 2 , wherein the slot of the adapter body includes an end wall and the stem portion of the bifurcated clip includes a spring-retainer portion, and wherein a spring is disposed between the end wall and the spring-retainer portion.

4. The adapter of claim 1 , wherein the adapter is configured to release the implant by sliding the bifurcated clip to its extended position.

5. The adapter of claim 1 , wherein each of the pair of bifurcated arms includes a protrusion extending from an interior surface of the bifurcated arm, and wherein the protrusion is configured to engage a valley of a serrated edge of the implant.

6. The adapter of claim 1 , wherein an outer surface of each of the bifurcated arms is flared outward at the leading end of the bifurcated arm and the slot of the adapter body includes a surface that is angled such that when the bifurcated clip slides from the extended position to the retracted position the outer surface of the bifurcated arm contacts the surface to force the bifurcated arm inward toward the longitudinal axis.

7. An implant kit comprising:

an adapter having a first end, a second end, and a longitudinal axis extending from the first end to the second end, wherein the first end is configured for removably receiving and engaging an implant and the second end is configured for coupling to a driver shaft of an implant driving tool and wherein the first end comprises:

an adapter body having a first end and a second end;

a slot provided within the adapter body, extending longitudinally therein and open at the first end of the adapter body; and

a bifurcated clip having a stem portion and a pair of bifurcated arms received within the slot wherein the stem portion extends through the second end of the adapter body and the bifurcated clip is slidable within the slot between an extended position and a retracted position; and

an implant preloaded into the first end of the adapter, said implant comprising:

an elongated threaded portion; and

a blade portion extending from the elongated threaded portion, and having two serrated edges, wherein the blade portion is received in the first end of the adapter and the elongated threaded portion of the implant is coaxially aligned with the longitudinal axis of the adapter;

wherein when the bifurcated clip is in the retracted position the bifurcated arms are in a closed position and the blade portion of the implant is retained between the pair of bifurcated arms.

8. The implant kit of claim 7 , wherein the bifurcated clip is spring-biased for keeping the bifurcated clip in the retracted position.

9. The implant kit of claim 8 , wherein the slot of the adapter body includes an end wall and the stem portion of the bifurcated clip includes a spring-retainer portion, and wherein a spring is disposed between the end wall and the spring-retainer portion.

10. The implant kit of claim 7 , wherein the implant can be released by sliding the bifurcated clip to its extended position.

11. The implant kit of claim 7 , wherein the bifurcated clip is thread-biased for keeping the bifurcated clip in the retracted position.

12. The implant kit of claim 11 , wherein the second end of the adapter body comprises a retaining nut that is rotatable about the longitudinal axis, the retaining nut having a threaded bore extending along the longitudinal axis,

wherein the stem portion of the bifurcated clip has a screw threaded portion that extends through the threaded bore of the retaining nut,

whereby the bifurcated clip is moved between the extended position and the retracted position by rotating the retaining nut.

13. The implant kit of claim 7 , wherein each of the pair of bifurcated arms has a thickness that is substantially the same as a thickness of the blade portion of the implant.

14. The implant kit of claim 7 , wherein each of the pair of bifurcated arms includes a protrusion extending from an interior surface of the bifurcated arm and each of the two serrated edges of the implant include at least one valley, and wherein the protrusion is configured to engage the at least one valley.

15. The implant kit of claim 7 , wherein an outer surface of each of the bifurcated arms is flared outward at the leading end of the bifurcated arm and the slot of the adapter body includes a sidewall that is angled such that when the bifurcated clip slides from the extended position to the retracted position the outer surface of the bifurcated arm contacts the sidewall to force the bifurcated arm inward toward the longitudinal axis.
