Abstract: A surgical stapling device includes a staple reload and a handle assembly that supports a drive rack, a motor assembly, a gear assembly, a reload select mechanism, and a safety toggle mechanism. The gear assembly is adapted to facilitate uncoupling of the motor assembly from the drive rack to allow manual movement of the drive rack. The reload select mechanism allows the length of a stroke of the drive rack to be selectively adjusted to allow the stapling device to accommodate different length staple reloads. The safety toggle mechanism is provided to move the stapling device from a non-firing state to a firing state to allow for firing of the stapling device.

Abstract: A reload for a surgical stapling apparatus includes a shaft assembly and an end effector secured to the shaft assembly. The end effector includes an anvil assembly, a cartridge assembly, and a firing assembly including a drive beam and a carriage, the drive beam and the carriage coupled together by a firing cable and a retraction cable that move the drive beam through the end effector as the carriage moves through the shaft assembly.

Abstract: A handle assembly (12) of a hand-held surgical instrument (10) includes a handle housing (26), a motor (36), and a dual thread lead screw (46) operably coupled to the motor (36) and configured to move proximally and/or distally in response to an actuation of the motor (36). A first thread pitch of the lead screw (46) is suitable for effecting a closing of jaw members (20a, 20b) of an end effector (20), and a second thread pitch of the lead screw (46) is suitable for effecting a stapling function of the end effector (20).

Abstract: A surgical device includes a powered handle assembly, an adapter assembly extending from the handle assembly, and a tool assembly that is mounted to the adapter assembly about a pivot member. The handle assembly includes a clutch that is movable between an articulation position and a clamp/fire position. In the articulation position, the handle assembly is configured to provide powered articulation of the tool assembly about the pivot member. In the clamp/fire position, the handle assembly is configured to provide actuation of the surgical device.

Abstract: Disclosed is a surgical stapling device (10). It includes a tool assembly (16) including a cartridge assembly (30a), an anvil assembly (32a), and a drive assembly (34). The drive assembly (34) includes a working member (52) and a first knife (74) that is pivotally supported on the working member (52) and has a first cutting edge (74a). The first knife (74) is positioned to extend between the cartridge and anvil assemblies (30a, 32a) such that the first cutting edge (74a) extends across a tissue gap of the tool assembly (16) when the tool assembly (16) is in the clamped position.
