A method of creating a tissue thickness compensator is disclosed. The method comprises dispensing oxidized regenerated cellulose onto a cover sheet, folding the cover sheet to at least partially capture the oxidized regenerated cellulose therein, and creating the tissue thickness compensator by applying a seal to the folded cover sheet.

Layer of material for a surgical end effector

In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.

End effector coupling arrangements for a surgical cutting and stapling instrument

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.

Detachable motor powered surgical instrument

A staple cartridge assembly comprising a tissue thickness compensator is disclosed. The tissue thickness compensator comprises a first fibrous, woven material and a second fibrous, woven material. The first fibrous, woven material comprises a density which is different than the density of the second fibrous, woven material. The tissue thickness compensator is configured to expand upon contact with a fluid in order to apply a compressive force to tissue captured within staples.

Methods for forming an implantable layer onto a staple cartridge are disclosed.

Method for applying an implantable layer to a fastener cartridge

A surgical stapling system is disclosed comprising a proximal housing portion, a distal housing portion removably coupleable to the proximal housing portion at a coupling interface, a motor, and a power source in electrical communication with the motor along an electrical communication pathway that does not traverse the coupling interface. The power source is configured to provide energy to the motor along the electrical communication pathway. The power source is permitted to provide energy to the motor based on the distal housing portion being coupled to the proximal housing portion.

Surgical stapling system

A surgical system comprising a surgical instrument, a motorized system, and a control system is disclosed. The surgical instrument comprises an end effector comprising a first jaw and a second jaw movable relative to the first jaw. The surgical instrument further comprises a threaded drive shaft, a firing member drivable by the threaded drive shaft, and a closure system configured to move the second jaw. The motorized system is configured to drive the threaded drive shaft and the closure system. The control system comprises a closure circuit configured to actuate the motorized system to move the second jaw toward a closed position, a firing circuit configured to actuate the motorized system to move the firing member toward a fired position, and an input interface configured to receive inputs from a user. The firing circuit is prevented from being actuated until the second jaw has been placed in the closed position.

Surgical System

A surgical instrument configured to be coupled to a robotic surgical system is disclosed. The surgical instrument comprises an end effector, a threaded drive shaft, a firing member drivable by the threaded drive shaft, a closure system configured to move a iaw of the end effector toward a closed position, and a housing assembly coupleable with the robotic surgical system and comprising an array of electrical contacts. The surgical instrument further comprises a first motor configured to drive the closure system, a second motor configured to drive the threaded drive shaft, a first decoupleable electrical contact configured to supply power to the first motor from a power system, and a second decoupleable electrical contact configured to supply power to the second motor from the power system. The power system is selectively interrupted unless a signal is provided to the power system from the robotic surgical system.

Surgical system

A stapling instrument for use with a surgical robot is disclosed. The stapling instrument comprises an interface including a plurality of rotary members, a shaft rotatable about a longitudinal axis by a first rotary member, an end effector rotatably connected to the shaft about an articulation joint, an articulation cable, a coupling member, and a firing cable. The end effector comprises a first jaw, a second jaw, and a staple cartridge comprising staples. The articulation cable operably connects to a second rotary member and is operable to pull the articulation cable and articulate the end effector. The coupling member is movable through a first stroke to move the second jaw toward the first jaw and movable through a second stroke to fire the staples. The firing cable operably connects to a third rotary member and is operable to drive the coupling member through the first stroke and the second stroke.

Stapling instrument for use with a surgical robot

A surgical stapling assembly comprising a firing member, an end effector, a closure member, and a shaft including an attachment interface is disclosed. The surgical stapling assembly is configured to be attached to a surgical instrument interface by way of the attachment interface. The end effector comprises a first jaw, a second jaw, and a staple cartridge comprising staples configured to be ejected by the firing member. The second jaw is movable relative to the first jaw between an open position, a fully-clamped position, and a collapsed position. The end effector further comprises an interconnection between the first jaw and the second jaw defining a rotational axis about which the second iaw is movable relative to the first iaw. The rotational axis is shiftable toward and away from the first iaw as the second iaw is moved between the open position, the fully-clamped position, and the collapsed position.

A surgical device comprising a first clamping member, a second clamping member, an electric motor, and a control system is disclosed. The electric motor is configured to drive at least one of the first clamping member and the second clamping member toward a predetermined tissue gap between the first clamping member and the second clamping member to clamp the tissue of a patient. The control system is configured to monitor a parameter of the electric motor. The parameter is indicative of a clamping force exerted to the tissue by the first clamping member and the second clamping member. The control system is further configured to control the electric motor based on the parameter to limit the clamping force to a predetermined maximum limit.
