A surgical instrument for use with a robotic system that has a control unit and a shaft portion that includes an electrically conductive elongated member that is attached to a portion of the robotic system. The elongated member is configured to transmit control motions from the robotic system to an end effector.

An endoscopic surgery system includes a plurality of staples and an endoscopic applicator having a staple cartridge for loading transversely arranged staples. The staples have a central region and two side limbs and the applicator has a mobile body for holding a staple to be applied, the staple being arranged in a transverse plane, and for ensuring the deformation of same by bending in relation to the axis of symmetry of the staple.

Devices and methods are provided for stabilizing fasteners post-deployment. Devices and methods are also provided for facilitating ejection of surgical fasteners from a cartridge. Devices and methods are also provided for guiding surgical fasteners. Devices and methods are also provided for facilitating closing and clamping of an end effector of a surgical device. Devices and methods are also provided for securing fasteners and adjunct materials to tissue. Devices and methods are also provided for removably coupling a cartridge to an end effector of a surgical device. Devices and methods are also provided for locking a surgical device based on loading of a fastener cartridge in the surgical device. Devices and methods are provided for adjusting a tissue gap of an end effector of a surgical device. Devices and methods are also provided for manually retracting a drive shaft, drive beam, and associated components.

A detachable motor-powered surgical instrument. The instrument may include a housing that includes at least one engagement member for removably attaching the housing to an actuator arrangement. A motor is supported within the housing for supplying actuation motions to various portions of a surgical end effector coupled to the housing. The housing may include a contact arrangement that is configured to permit power to be supplied to the motor only when the housing is operably attached to the actuator arrangement.

A surgical instrument for use with a robotic system that has a control unit and a shaft portion that includes an electrically conductive elongated member that is attached to a portion of the robotic system. The elongated member is configured to transmit control motions from the robotic system to an end effector.

Stapling assemblies for use with a surgical stapler are provided. In one exemplary embodiment, a stapling assembly can include a cartridge and a knitted adjunct that is configured to be releasably retained on the cartridge. The adjunct includes first fibers, second fibers, and spacer fibers, in which the first fibers and the spacer fibers are intertwined to form a top layer of the adjunct, the second fibers and the spacer fibers are intertwined to form a bottom layer of the adjunct, and the first fibers, the second fibers, and the spacer fibers are intertwined to form at least one finished edge extending between the top and bottom layers such that the at least one finished edge substantially prevents fraying.

Disclosed is an end effector of a surgical linear stapler, which includes a staple cartridge, an anvil, a pusher unit, a driving wedge, a stabilizer unit and a blade unit, wherein the stabilizer unit is arranged on the staple cartridge while neighboring on the pusher unit and at least partially discharged from the staple cartridge by the driving wedge so as to hold tissue placed in between the staple cartridge and the anvil.

A treatment device includes: an operating section; an elongated insertion section connected to the operating section; a pair of clamp members provided at the distal end of the insertion section so as to be openable and closable relative to each other; a movable member that is moved so as to push staples relative to tissue sandwiched between the clamp members; and a coil member that is arranged so as to pass through the insertion section in the longitudinal direction and that transmits a pressing force from the operating section to the movable member.

Staple cartridge assemblies for use with surgical stapling instruments and methods for manufacturing the same are provided. Scaffolds for use with a surgical staple cartridge and methods for manufacturing the same are also provided.

An endoscopic stapling device for tissue resection has an asymmetrical tool assembly that delivers a greater number of staples, or rows of staples, to healthy tissue that remains in a patient, and fewer number of staples, or rows of staples, to diseased or damaged tissue to be resected and removed from the patient. The tool assembly includes an asymmetric cartridge assembly and an asymmetric anvil assembly for applying the staples to the resected and healthy tissues. The endoscopic stapling device also includes an asymmetric drive assembly for actuating the tool assembly.
