Abstract

A surgical stapling instrument can comprise, one, a handle comprising an actuator and, two, an end effector comprising a proximal end, a distal end, and a longitudinal axis extending between the proximal end and the distal end. The end effector can further comprise a first jaw configured to support staples comprising staple legs and, in addition, a second jaw supporting a matrix element opposite the staples, wherein one of the jaws is movable toward the other in order to engage the matrix element with the staple legs. The stapling instrument can further comprise a cam operably coupled with the actuator, wherein the cam is movable along the longitudinal axis to deform the staple legs.
