A clip cartridge assembly for use with a reposable surgical clip applier includes a clip tray, a plurality of surgical clips, and a cover. The clip tray includes a plurality of distally oriented, deflectable, resilient fingers projecting from a base wall thereof. Each resilient finger terminates in a distal shoulder and a proximal end of the clip tray is configured for selective connection with a clip pusher bar of an endoscopic assembly of the reposable surgical clip applier. The cover includes a plurality of distally oriented, deflectable, resilient fingers projecting within a channel defined through proximal and distal ends thereof. Each resilient finger of the cover terminates in a distal shoulder and the cover includes a pair of opposed slots defined within sidewalls of the channel configured to slidably retain the clip tray and the plurality of surgical clips therein. A reposable surgical clip applier is also provided.

A surgical instrument can comprise a handle, a motor, and a shaft extending from the handle. The handle and/or the shaft can define a longitudinal axis. The surgical instrument can further comprise a fastener cartridge comprising a plurality of fasteners removably stored therein, an anvil configured to deform the fasteners, a closure drive configured to move the anvil toward and away from the fastener cartridge which is rotatable about the longitudinal axis, and a firing drive configured to deploy the fasteners from the fastener cartridge which is rotatable about the longitudinal axis. The surgical instrument can further comprise a transmission comprising a first operating configuration which connects the motor to the closure drive and a second operating configuration which connects the motor to the firing drive.

A surgical instrument is disclosed which comprises a staple firing system and a tissue cutting system. In various instances, the instrument is configured to prevent the tissue cutting system from being operated before the staple firing system has been fully actuated. In certain instances, the instrument is configured to prevent the tissue cutting system from being operated before the staple firing system has been actuated to sufficiently deform the staples.

An adapter assembly includes a cam housing defining a proximal cam slot and a distal cam slot, a first elongate shaft, and a second elongate shaft. The first elongate shaft has a proximal end portion received in the proximal cam slot, and a distal end portion configured to be coupled to a surgical loading unit. The second elongate shaft has a proximal end portion received in the distal cam slot, and a distal end portion configured to be coupled to the surgical loading unit. The first and second elongate shafts are configured to move in opposing longitudinal directions in response to a rotation of the cam housing to articulate the surgical loading unit.

A surgical stapling device is disclosed which includes a handle assembly, an endoscopic body portion and a tool assembly. The tool assembly is rotatably and pivotally supported on a distal end of the endoscopic body portion. A tool assembly rotation mechanism is provided which includes a rotation knob, a substantially rigid tube and a flexible member interconnecting the rigid tube to the tool assembly. The substantially rigid tube translates rotation of the rotation knob to rotation of the flexible member and provides a channel for passage of other components of the surgical stapling device.

A surgical device can include a first jaw, a second jaw opposing the first jaw, a clamp lever in communication with the first jaw and the second jaw and operable to move the first jaw, the second jaw, or both from a jaw nominal position to a jaw clamped position when an external force is imparted upon the clamp lever in a first direction, and a stop bias member that stops movement of the clamp lever when the external force is removed so that the first jaw and the second jaw are in the jaw nominal position at rest.

A surgical applicator for a fastener, the surgical applicator comprising: a handle; a trigger movable relative to the handle between an initial position, an actuated position, and an intermediate position between the initial position and the actuated position; and a lockout mechanism movable relative to the trigger between a locked position and an unlocked position, the lockout mechanism operatively arranged to: lock the trigger in the intermediate position when the trigger is moved from the initial position toward the actuated position; and permit movement of the trigger from the intermediate position toward the initial position or the actuated position when the lockout mechanism is moved from the locked position to the unlocked position.

A treatment tool for an endoscope includes a transmitting part that transmits an operation of an operating part to a grip part and a bendable part of a distal end part. The transmitting part has a first transmitting member hat is moved to an operating part side based on the operation of the operating part and closes the grip part and a second transmitting member that is moved to the operating part side based on the operation of the operating part and bends the bendable part. In response to the operation of the operating part, first, the first transmitting member is moved to the operating part side, and the second transmitting member is moved to the operating part side after the start of the movement of the first transmitting member.

A surgical end effector for use with a surgical instrument that includes an elongate shaft assembly that includes a rotary output drive shaft is disclosed. An elongate channel is attached to the elongate shaft assembly. An anvil frame that comprises a proximal end and a distal end is selectively movable between open and closed positions relative to the elongate channel. An anvil concentric drive member is rotatably supported by the anvil frame and is configured to receive rotary drive motions from the rotary output drive shaft of the surgical instrument when the anvil frame is in the closed position. A firing member is in driving engagement with the anvil concentric drive member for linear travel through the end effector.

A powered handle for a surgical stapler can have a drive system including an electric motor. The powered handle can include a manual articulation mechanism to articulate a jaw assembly coupled to a reload shaft connected to the handle. The manual articulation mechanism can include a ball screw mechanism that translates an articulation member responsive to rotation of an articulation knob. The articulation mechanism includes a release function that allows the jaw assembly to return to a longitudinally centered orientation. The powered handle includes a battery pack serving as a power supply for the drive system. A control system can control actuation of the motor based on user inputs and operating parameters of the stapler. The powered handle can include a manual return mechanism.
