Abstract: A surgical stapling assembly is disclosed. The surgical stapling assembly can include a first jaw, a second jaw, an articulation joint, a closure drive comprising a first flexible rotary drive extending through the articulation joint, and a firing drive comprising a second flexible rotary drive extending through the articulation joint and rotatable independent of the first flexible rotary drive. The surgical stapling assembly can further include a 3D-printed component. The surgical stapling assembly can be configured to form different staple shapes, such as non-planar staples and planar staples, can include an eccentrically-driven firing assembly, and/or can include a floatable component. The surgical stapling assembly can include a staple cartridge including a longitudinal support beam.

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.

Abstract: A staple driver actuator for a surgical stapler includes a base having at least one bottom surface. The bottom surface defines a plane and is configured to slide longitudinally relative to a jaw of the surgical stapler. The staple driver actuator also includes a plurality of rails extending upwardly from the base. Each of the plurality of rails includes at least one cam surface, and each of the cam surfaces is inclined relative to the plane. The plurality of rails includes a laterally- opposed pair of outer rails and a laterally-opposed pair of inner rails. The staple driver actuator further includes a distal nose extending distally from at least a portion of the base and having at least one ledge surface. The ledge surface faces upwardly, is parallel to the plane, and is at least partially positioned distally relative to each of the outer and inner rails.

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.

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.

Abstract: A surgical stapling instrument comprising a cartridge jaw configured to receive a staple cartridge, an anvil jaw, and a firing member configured to eject the staples from the staple cartridge during a firing stroke is disclosed. The anvil jaw comprises a stop extending into the cartridge jaw which prevents the staple cartridge from contacting the firing member when the staple cartridge is inserted into the cartridge jaw.
