    Abstract: A surgical instrument comprises a body, shaft, and end effector. The shaft couples the end effector and body together. The end effector comprises an anvil and lower jaw configured to receive a surgical staple cartridge. The anvil is configured to pivot toward and away from the staple cartridge and lower jaw. The shaft assembly comprises a knife member configured to longitudinally translate to thereby substantially simultaneously cut clamped tissue and staple the severed tissue. The end effector may comprise lockout features configure to prevent longitudinal translation of the knife member. The end effector or staple cartridge may comprise lockout bypass features configured to prevent lockout of the knife member. These lockout bypass features may operate to permit longitudinal translation of the knife member once or multiple times. The end effector may comprise features configured to ensure proper alignment of the anvil relative to the staple cartridge.

    Abstract: A surgical instrument includes a body assembly, an end effector, and a shaft assembly. The body assembly includes at least one electrical connection. The end effector is operable to treat tissue. The shaft assembly extends between the body assembly and the end effector along a shaft axis. The shaft assembly includes a nozzle, a closure tube, and a fluid blocker. The nozzle includes at least one housing. The at least one housing includes a recess. The closure tube is configured to rotate relative to the body assembly about the shaft axis. The fluid blocker is disposed within the recess of the nozzle. The fluid blocker is configured to contact the closure tube to prevent fluid from entering the nozzle and reaching the at least one electrical connection disposed within the body assembly.

    Abstract: An apparatus comprises a shaft, an end effector, an articulation joint, and an articulation drive assembly. The shaft has a longitudinal axis. The end effector is operable to staple tissue. The articulation joint couples the shaft with the end effector. The end effector is pivotable at the articulation joint to selectively deflect the end effector away from the longitudinal axis of the shaft. The articulation drive assembly is operable to pivot the end effector at the articulation joint. The articulation drive assembly comprises a first link and a second link. The first link is longitudinally translatable relative to the shaft assembly. The distal end of the first link is pivotably coupled with the proximal end of the second link. The distal end of the second link is pivotably coupled with the end effector. The articulation drive assembly articulates the end effector in response to longitudinal translation of the first link.

    Abstract: A surgical stapler includes a body, a shaft assembly, and an end effector configured to receive a staple cartridge. The end effector is actuatable between an open state for receiving tissue and a closed state for clamping the tissue. A closure system operatively coupled with the end effector is operable to actuate the end effector from the open state to the closed state. A firing system operatively coupled with the end effector is actuatable to fire the end effector to staple and cut the clamped tissue. A lockout member operatively coupled with the closure system and the firing system is configured to inhibit actuation of the closure system to prevent closure of the end effector when an unspent staple cartridge is absent from the end effector. The lockout member is also configured to inhibit actuation of the firing system to prevent repeated firing with the same staple cartridge.
