Abstract
Abstract An anvil for a surgical fastener assembly is disclosed. The anvil has a staple-forming surface upon which a plurality of pockets are displayed for staple formation. First and second sidewalls extend from the staple-forming surface. Cutting guides extend laterally from the sidewalls to provide a uniform surface upon which a user can apply pressure with a scalpel to staple tissue in a direction generally parallel to the vertical staple row. An even margin can be maintained between the staple row and the cut line, thus increasing the degree of confidence and skill that the user can employ when cutting the fastened tissue.
