Abstract

A system including a bone punch tool and a needle guide. The bone punch tool can include a support arm having a support arm proximal portion and a support arm distal portion, a pivot arm having a pivot arm proximal portion and a pivot arm distal portion, and an arcuate punch configured to punch through bone. The pivot arm distal portion can be pivotably coupled to the support arm distal portion, such that the pivot arm proximal portion is configured to be moved away from the support arm proximal portion to extend the arcuate punch into a punch position to punch an arcuate hole through bone. The needle guide can be configured to guide a needle through the arcuate hole.

Claims

1. A bone punch apparatus comprising:

a support arm having a support arm proximal portion and a support arm distal portion;

a pivot arm having a pivot arm proximal portion and a pivot arm distal portion, the pivot arm distal portion pivotably coupled to the support arm distal portion; and

an arcuate punch configured to punch through bone, the arcuate punch coupled to the pivot arm distal portion;

wherein the pivot arm proximal portion is configured to be moved away from the support arm proximal portion to cause the arcuate punch to extend into a punch position.

2. The bone punch apparatus of claim 1, wherein the pivot arm proximal portion is configured to be moved toward the support arm proximal portion to cause the arcuate punch to retract into a retracted position.

3. The bone punch apparatus of claim 1, wherein the pivot arm pivots about a pivot point positioned at the support arm distal portion at a center of curvature of the arcuate punch.

4. The bone punch apparatus of claim 1, further comprising:

a protrusion extending from the support arm distal portion and configured to receive a bone piercing tip of the arcuate punch when in the punch position.

5. The bone punch apparatus of claim 4, further comprising:

a housing coupled to the support arm distal portion, the housing and the protrusion together defining a receptacle configured to receive a bone portion.

6. The bone punch apparatus of claim 5, wherein the receptacle is a u-shaped receptacle configured to receive a portion of a sternum.

7. The bone punch apparatus of claim 1, wherein the arcuate punch is configured to form an arcuate hole through a bone portion.

8. The bone punch apparatus of claim 1, further comprising:

a locking member configured to urge the pivot arm proximal portion toward the support arm proximal portion.

9. A bone punch apparatus comprising:

a support arm having a support arm proximal portion, a support arm distal portion, and a support arm alignment guide;

a pivot arm having a pivot arm proximal portion and a pivot arm distal portion, the pivot arm distal portion pivotably coupled to the support arm distal portion; and

an arcuate punch configured to punch through bone, the arcuate punch coupled to the pivot arm distal portion;

wherein the support arm alignment guide is configured to indicate an orientation of the arcuate punch.

10. The bone punch apparatus of claim 9, wherein:

the pivot arm proximal portion is configured to be moved away from the support arm proximal portion to cause the arcuate punch to extend into a punch position; and

the pivot arm proximal portion is configured to be moved toward the support arm proximal portion to cause the arcuate punch to retract into a retracted position.

11. The bone punch apparatus of claim 9, wherein the support arm alignment guide comprises a window.

12. The bone punch apparatus of claim 11, wherein a width of the window corresponds to a width of the arcuate punch.

13. The bone punch apparatus of claim 9, wherein the support arm alignment guide is configured to align with a completed punch hole.

14. The bone punch apparatus of claim 9, wherein the pivot arm comprises a pivot arm alignment guide configured to indicate an orientation of the arcuate punch.

15. A system comprising:

a bone punch tool configured to form an arcuate hole through a bone, the bone punch tool comprising;

a support arm having a support arm proximal portion and a support arm distal portion;

a pivot arm having a pivot arm proximal portion and a pivot arm distal portion, the pivot arm distal portion pivotably coupled to the support arm distal portion; and

an arcuate punch configured to punch through the bone, the arcuate punch coupled to the pivot arm distal portion;

wherein the pivot arm proximal portion is configured to be moved away from the support arm proximal portion to cause the arcuate punch to extend into a punch position; and

a needle guide configured to guide a needle through the arcuate hole.

16. The system of claim 15, wherein the arcuate punch is dimensioned to form the arcuate hole with geometry corresponding to an arcuate geometry of the needle.

17. The system of claim 16, wherein the needle guide comprises:

a handle;

an arcuate portion coupled to the handle, the arcuate portion configured to be inserted into the arcuate hole; and

a grasping portion at an end of the arcuate portion, the grasping portion configured to grasp a tip of the needle.

18. The system of claim 17, wherein the grasping portion comprises a slot formed in the arcuate portion.

19. The system of claim 17, wherein the grasping portion comprises an aperture and at least one slot intersecting the aperture, such that the end of the arcuate portion is configured to expand with receipt of the needle within the aperture.

20. The system of claim 17, wherein the arcuate portion is configured to be removed from the arcuate hole while grasping the needle, such that the needle guide is configured to guide the needle through the arcuate hole.
