Abstract
Disclosed is a novel aortic punch having a cutter on the end of a hollow body member. The hollow body member is slidable along a non-rotating shaft. On the end of the shaft is an anvil, and helical drive structure is provided between the hollow body member and the shaft or another non-rotating element adjacent the hollow body member. The helical drive structure comprises a flange receivable in a slot such that when a thumb button is pushed into a finger grip, the hollow body slides along, and rotates relative to, the shaft. This movement of the hollow body causes the cutter on the end of the hollow body to rotate relative to the anvil located on the end of the shaft as the cutter slides past the anvil. This rotation of the cutter provides that the aortic punch can be used to achieve a clean and accurate cut to the wall of an aorta during heart surgery.
