Abstract: A surgical stapling instrument comprising an articulatable end effector including a staple cartridge is disclosed. The stapling instrument further comprises an articulation drive configured to articulate the end effector and a staple firing drive configured to fire the staples from the staple cartridge during a staple firing stroke. The articulation drive is selectively engageable with the staple firing drive to articulate the end effector and decoupled from the staple firing drive during the staple firing stroke. The stapling instrument further comprises a control system that is configured to compensate for the net displacement of the staple firing drive that occurs when articulating the end effector.

IPC: A61B17/072

Abstract: A surgical instrument comprising an articulatable end effector and an articulation control system is disclosed. The articulation control system comprises actuators that, when actuated, cause the end effector to articulate in predetermined directions. When the end effector is rotated downwardly, the articulation control system flips, or switches, the response to the inputs from the actuators.

IPC: A61B17/072

Abstract: A surgical stapling instrument comprising a tissue cutting knife movable through a staple cartridge to perform a staple firing stroke is disclosed. The stapling instrument further comprises a lockout system configured to prevent the tissue cutting knife from being moved through the staple firing stroke if the staple cartridge is missing from the stapling instrument and/or if the staple cartridge has been previously fired. The lockout system comprises a flexible spring that acts on the bottom of the tissue cutting knife at the initiation of the staple firing stroke to push the tissue cutting knife into a lockout recess if the staple cartridge is missing or has been previously fired.
