Surgical stapler with a bendable end effector
A surgical stapler having a selectively bendable end effector is provided. A staple holding jaw of the end effector is coupled to another jaw for grasping tissue to be stapled. The stapler can adapted to drive staples into tissue having a pattern conforming with the selected shape of the end effector. In particular, the end effector can be adapted to drive staples in a linear pattern when the end effector orients staples in a substantially linear configuration. The end effector can also be adapted to drive staples in a non linear pattern when the end effector orients staples in a non linear configuration. Methods of stapling tissue with a stapler having a bendable end effector are also discussed.
