    Abstract: A surgical instrument end effector includes a first jaw configured to receive a staple cartridge and a second jaw that includes an anvil having a plurality of staple forming pockets. The first and second jaws are operable to clamp and staple tissue positioned therebetween. A tip member is movably disposed at a distal end of the anvil and is configured to toggle relative to the anvil between a first discrete position and a second discrete position. The tip member in the first discrete position is oriented angularly toward the first jaw, and the tip member in the second discrete position is oriented angularly away from the first discrete position.

    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.

    Abstract: An apparatus that includes a body, a shaft, and an end effector. The end effector includes a first jaw, a second jaw, and a tip. The second jaw includes an anvil. At least one of the first jaw or the second jaw is configured to move relative to the other of the first jaw or the second jaw between an open position and a closed position. The tip is connected with the anvil. The tip includes a deformable member. The tip is movable relative to the anvil between first and second discrete positions using the deformable member. The tip remains in the first discrete position located closer toward the cartridge until the deformable member is acted upon by an external input force. The tip remains in the second discrete position that is located further from the cartridge until the deformable member is acted upon by the external input force.

    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 base also has at least one top surface parallel to the plane. The staple driver actuator further includes at least one rail extending upwardly from the base. The rail includes at least one first cam surface. The first cam surface is inclined relative to the plane, and the first cam surface is longitudinally aligned with at least a portion of the at least one top surface.

    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.

    IPC: A61B17/072

    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.

At least one of the first jaw or the second jaw is configured to move relative to the other of the first jaw or the second jaw between an open position and a closed position. The tip is connected with the anvil. The tip includes a deformable member. The tip is movable relative to the anvil between first and second discrete positions using the deformable member. The tip remains in the first discrete position located closer toward the cartridge until the deformable member is acted upon by an external input force. The tip remains in the second discrete position that is located further from the cartridge until the deformable member is acted upon by the external input force.
