Abstract: A powered surgical stapling device includes an end effector having a stationary anvil and a cartridge assembly that is supported for pivotal movement in relation to the anvil. In embodiments, the end effector includes a housing that supports an input shaft, an anvil fixedly supported on the housing, and a cartridge assembly pivotally supported in relation to the housing and the anvil. The cartridge assembly includes a channel that is pivotally supported on the housing. A lead screw is positioned within the channel and supports an internally threaded dynamic clamping member. The lead screw is secured to the input shaft by a universal joint such that rotation of the input shaft effects rotation of the lead screw and longitudinal translation of the dynamic clamping member along the lead screw. The universal joint facilitates the translation of the rotatable movement of the input shaft into rotation of the lead screw while allowing pivotal movement of the lead screw in relation to the input shaft.

Abstract: An adapter assembly includes a switch actuator, an actuation bar, and a latch. The switch actuator is movable between a proximal position, in which the switch actuator actuates a switch, and a distal position. The latch is movable between a first position, in which the latch permits proximal movement of the switch actuator, and a second position, in which the latch prevents proximal movement of the switch actuator. The latch is configured to move from the first position toward the second position in response to the actuation bar moving toward a proximal position.

Abstract: The present disclosure relates to a surgical device including an adapter assembly for selectively interconnecting an end effector and the device housing. The adapter assembly includes at least one drive converter assembly that converts and transmits a rotation of the rotatable drive shaft to an axial translation of at least one axially translatable drive member of the end effector. A first drive converter assembly includes a first drive element, a nut, an articulation sleeve, an articulation bearing, and an articulation link. Rotation of the rotatable drive shaft results in rotation of the first drive element. Rotation of the first drive element results in axial translation of the nut, the articulation sleeve, the articulation bearing, the articulation link, and the at least one axially translatable drive member of the end effector.

Abstract: A surgical stapling device includes a handle assembly, an elongate body extending distally from the handle assembly, and a tool assembly. The tool assembly is mounted onto the distal portion of the elongate body for articulation and includes a staple cartridge that supports a plurality of staples and pushers. An actuation sled is movable through the staple cartridge to eject staples from the staple cartridge and a clamp member is movable through the tool assembly to move the tool assembly from an open position to an approximated position and to advance the actuation sled through the staple cartridge to eject staples and transect tissue. In order to minimize the space for the firing assembly in the proximal portion of the tool assembly, the actuation sled and clamp member are supported in a nested relationship in a pre-actuated state of the tool assembly. The clamp member is subsequently moved to a position proximal of the actuation sled during a firing stroke of the stapling device.
