Rotating aortic punch

An aortic punch comprising:

• a finger grip;
• a pin secured within said finger grip;
• a hollow body having a first end and a second end;
• a thumb button having a slot thereon, said thumb button in contact with said first end of said hollow body, said thumb button pushable into said finger grip, said pin secured within said finger grip received within said slot on said thumb button;
• a compression spring within said finger grip, said compression spring located between an inwardly extending lip of said finger grip and a washer engaged against an outwardly extending shoulder on said hollow body;
• a cutter on said second end of said hollow body;
• a shaft within said hollow body, said shaft having an end, said pin securing said shaft, said hollow body slidable along said shaft;
• an anvil on said end of said shaft;
• and
• a helical drive flange on said shaft, said helical drive flange receivable in a slot on an inwardly extending shoulder of said hollow body, wherein said helical drive flange and said slot on said hollow body are shaped to provide that sliding said hollow body along said shaft causes said slot on said hollow body to ride along said helical drive flange on said shaft causing said hollow body to rotate relative to said shaft and causing said cutter on said end of said hollow body to rotate relative to said anvil on said end of said shaft as said cutter moves past said anvil.

An aortic punch comprising:

• a finger grip;
• a pin secured within said finger grip;
• a hollow body having a first end and a second end;
• a shaft within said hollow body and secured by said pin, said shaft having an end, said hollow body slidable along said shaft;
• a thumb button having a slot thereon, said thumb button securably engaged with said first end of said hollow body, said thumb button pushable into said finger grip, said pin secured within said finger grip received within said slot on said thumb button, wherein said thumb button pushes said hollow body causing said hollow body to slide along said shaft when said thumb button is pushed into said finger grip;
• a compression spring within said thumb button, said compression spring having a first end engaged with said thumb button and having a second end engaged with said shaft;
• a cutter on said second end of said hollow body;
• an anvil on said end of said shaft;
• a sleeve secured within said finger grip by said pin, said sleeve having a slot thereon;
• and
• a helical drive flange on said hollow body, said helical drive flange receivable in said slot on said sleeve within said finger grip, wherein said helical drive flange and said slot are shaped to provide that sliding said hollow body along said shaft causes the helical drive flange to ride in the slot causing said hollow body to rotate relative to said shaft and causing said cutter on said end of said hollow body to rotate relative to said anvil blade on said end of said shaft as said cutter moves past said anvil.
