Abstract

In various embodiments, a targeting guide is disclosed. The targeting guide includes a handle defining a targeting hole and a targeting tower configured to be coupled to the handle. The targeting tower defines at least a first guide hole and a second guide hole. Each of the first and second guide holes are sized and configured to receive a respective first guide pin and second guide pin therethrough. The first and second guide pins are configured to indicate alignment of a k-wire inserted through the targeting hole defined by the handle. Methods of using a targeting guide are also disclosed.

First claim

What is claimed is:

1. A targeting guide, comprising:
a handle defining a targeting hole;
a targeting pin configured to be coupled to the handle, wherein the targeting pin defines the targeting hole; and
a targeting tower configured to be coupled to the handle, the targeting tower defining at least a first guide hole and a second guide hole, wherein each of the first and second guide holes are sized and configured to receive a respective first guide pin and second guide pin therethrough, and wherein the first and second guide pins are configured to indicate alignment of a k-wire inserted through the targeting hole defined by the handle, the targeting tower further including an opening sized and configured to slideably couple the targeting tower to a targeting shaft of the targeting pin, wherein an inner wall of the targeting tower that defines the opening includes two tabs that extend inwardly so as to be arranged in spaced-apart confronting relation to thereby provide a preferred orientation of the targeting pin.

2. The targeting guide of claim 1 , wherein the targeting pin comprises a head and the targeting shaft, wherein the targeting shaft extends at a non-zero angle with respect to the handle.

3. The targeting guide of claim 1 , wherein the at least one guide hole is sized and configured to receive a guide sleeve therein.

4. The targeting guide of claim 1 , wherein the handle comprises a first handle portion and a second handle portion, wherein the second handle portion is coupled to a distal end of the first handle portion at a predetermined, non-zero angle.

5. The targeting guide of claim 1 , wherein the handle is configured to be coupled to the targeting tower by a slot formed on a first one of the handle or the targeting tower and a tab formed on a second one of the handle or the targeting tower.

6. The targeting guide of claim 1 , comprising a soft tissue guard configured to be coupled to the handle.

7. The targeting guide of claim 6 , wherein the soft tissue guard defines at least one hole sized and configured to receive the targeting pin therethrough.

8. A kit, comprising:
a targeting guide, comprising:
a handle;

a targeting pin configured to be coupled to the handle, wherein the targeting pin defines a targeting hole; and
a targeting tower coupled to the handle, the targeting tower defining a first guide hole, a second guide hole, and a targeting pin hole, wherein each of the first and second guide holes are sized and configured to receive a respective first guide pin and second guide pin, the targeting tower further including an opening sized and configured to slideably couple the targeting tower to a targeting shaft of the targeting pin, wherein an inner wall of the targeting tower that defines the opening includes two tabs that extend inwardly so as to be arranged in spaced-apart confronting relation to thereby provide a preferred orientation of the targeting pin;
at least one first targeting pin comprising a first head and a first targeting shaft having a first length; and
at least one second targeting pin comprising a second head and a second targeting shaft having a second length, wherein a circumference of the at first targeting shaft and a circumference of the second targeting shaft are equal, wherein each of the at least one first targeting pin and the at least one second targeting pin define a longitudinally extending divot that is complimentary with the two tabs so as to be configured to be slideably received within the targeting pin hole defined in the targeting tower, and wherein each of the at least one first targeting pin and the at least one second targeting pins are configured to position a k-wire inserted through a guide hole defined therethrough parallel to and out of plane of the first and second guide pins.

9. The kit of claim 8 , wherein the first and second guide holes are each sized and configured to receive a guide sleeve therein.

10. The kit of claim 8 , wherein the handle comprises a first handle portion and a second handle portion, wherein the second handle portion is coupled to a distal end of the first handle portion at a predetermined, non-zero angle.

11. The kit of claim 8 , wherein the handle is configured to be coupled to the targeting tower by a slot formed on a first one of the handle or the targeting tower and a tab formed on a second one of the handle or the targeting tower.

12. The kit of claim 8 , comprising a soft tissue guard configured to be coupled to the handle.

13. The kit of claim 8 , wherein the soft tissue guard defines at least one hole sized and configured to receive the at least first targeting pin or the at least one second targeting pin therethrough.
