Abstract

A multi-staple inserter and drill guide, and methods of use thereof, are disclosed therein. The orthopedic staples can also be used in addition to interfragmentary screws to apply further compression of the bone fragments.

First claim

What is claimed is:

1. An insertion system comprising:
a first staple including a first bridge and a first pair of legs each attached to the first bridge at a first elastic hinge region and a second staple that includes a second bridge and a second pair of legs each attached to the second bridge at a second elastic hinge region, and the first staple and the second staple are mounted to a delivery device; and
the delivery device capable of restraining and releasing the first staple and the second staple, wherein the delivery device strains the first bridge and the second bridge to configure the first staple and the second staple from an unrestrained state in which the first pair of legs and the second pair of legs are angled inwardly to a strained state in which the first pair of legs and the second pair of legs are substantially perpendicular to the bridge.

2. The insertion system as recited in claim 1 wherein the first staple and the second staple are identical.

3. The insertion system as recited in claim 1 wherein the first staple and the second staple comprise Nitinol.

4. The insertion system as recited in claim 1 including a first pin set comprising a first pin and a second pin extending from a first pin set support arm, a second pin set comprising a first pin and a second pin extending from a second pin set support arm, wherein the first staple and the second staple are released via a release maneuver, and the first pin and the second pin of the first pin set and the first pin and the second pin of the second pin set extend from the first pin set support arm and the second pin set support arm, respectively, in the same direction.

5. The insertion system as recited in claim 4 wherein the release maneuver comprises lateral movement of the first pin set support arm and the second pin set support arm.

6. The insertion system as recited in claim 1 including a first pin set comprising a first pin and a second pin extending from a first pin set support arm, a second pin set comprising a first pin and a second pin extending from a second pin set support arm, wherein the first pin and the second pin of the first pin set extend from the first pin set support arm in one direction, and the first pin and the second pin of the second pin set extend from the second pin set support arm in another direction opposite to the one direction.

7. The inserter system as recited in claim 6 wherein the first staple and the second staple are released via a release maneuver, and the release maneuver comprises rotational movement of the first pin set support arm and the second pin set support arm.

8. The insertion system as recited in claim 1 comprising:
a first pin set comprising a first pin and a second pin extending from a first pin set support arm,
a second pin set comprising a first pin and a second pin extending from a second pin set support arm,
a first handle extending from the first pin set support arm,
a second handle extending from the second pin set support arm, wherein the second handle is pivotally attached to the first handle,
wherein the first pin of the first pin set and the first pin of the second pin set are configured to support the first staple, the second pin of the first pin set and the second pin of the second pin set are configured to support the second staple, and the first staple and the second staple are released via a release maneuver.

9. The insertion system as recited in claim 8 wherein the first pin and the second pin of the first pin set and the first pin and the second pin of the second pin set extend from the first pin set support arm and the second pin set support arm, respectively, in the same direction.

10. The inserter system as recited in claim 9 wherein the release maneuver comprises lateral movement of the first pin set support arm and the second pin set support arm.

11. The insertion system as recited in claim 8 wherein the first pin of the first pin set extends in a different direction than the first pin of the second pin set, and the second pin of the first pin set extends in a different direction than the second pin of the second pin set.

12. The inserter system as recited in claim 11 wherein the release maneuver comprises rotational movement of the first pin set support arm and the second pin set support arm.

13. The inserter system as recited in claim 4 wherein the first pin set support arm includes a first support arm portion including the first pin of the first pin set and a second support arm portion including the second pin of the first pin set, and the second pin set support arm includes a first support arm portion including the first pin of the second pin set and a second support arm portion including the second pin of the second pin set, wherein the first pin of the first pin set and the first pin of the second pin set support for the first staple, and the second pin of the first pin set and the second pin of the second pin set support for the second staple.

14. A method of inserting at least two staples into a bone comprising:
moving a handle of a multi-staple delivery device in a first direction to configure at least two staples mounted to the multi-staple delivery device from an unrestrained state to a strained state to strain a bridge of the at least two staples to move a pair of legs of each of the at least two staples to be substantially perpendicular to the bridge;
inserting each of the pair of legs of the at least two staples into a set of holes in the bone; and
releasing the at least two staples from the body of the multi-staple delivery device.
