Abstract
A method is provided for forming a surgical stapler anvil with a first punch having a first plurality of protrusions and an opposing second punch having a second plurality of protrusions. A workpiece having first and second sides is positioned between the first and second punches. The first side is contacted by the first punch, thereby plastically deforming the first side with the first plurality of protrusions to displace material of the first side toward the second side. The second side is contacted by the second punch, thereby plastically deforming the second side to displace material of the second side toward the first side. A plurality of pockets is formed in the first side via the contact of the first punch with the first side and the contact of the second punch with the second side. Each of the pockets is configured to deform a leg of a surgical staple.
