Abstract: A surgical device with a powered in-line handle assembly that includes actuators for actuating and articulating an end effector of the surgical device allows for single handed operation of the surgical device. The handle assembly includes a battery that is received in a removable compartment in a battery cover to allow for removal and recycling of the battery following use. The handle assembly also includes a manual release mechanism that allows a firing rod assembly of the handle assembly to be manually retracted in emergency situations.

Abstract: A shell assembly includes a shell housing defining a cavity, a plurality of staples, a staple cartridge supported on the shell housing, a pusher assembly positioned within the cavity of the shell housing, and a hydraulic piston configured to engage the pusher assembly to impart axial displacement to the pusher assembly and form a fluid tight seal against the shell housing. The staple cartridge defines slots that receive the plurality of staples. The pusher assembly includes a plurality of pushers arranged in an annular configuration to eject the plurality of staples from the staple cartridge. Supply of a fluid into the cavity of the shell housing advances the hydraulic piston, which, in turn, advances the pusher assembly to eject the plurality of staples from the staple cartridge.

Abstract: A surgical stapling device includes an anvil assembly and a reload assembly that includes a knife and a knife carrier. The knife is releasably coupled to the knife carrier and is embedded in a cut ring of the anvil assembly when the stapling device is fired. The knife is separable from the knife carrier upon application of a predetermined force on the knife. The predetermined force is applied to the knife after the stapling device is fired by moving the anvil assembly in relation to the reload assembly from a clamped position to an open position.
