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;
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; and
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.

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.

13. 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; wherein the arcuate punch is dimensioned to form the arcuate hole with geometry corresponding to an arcuate geometry of the needle; and 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. - View Dependent Claims (14, 15, 16)
