An end effector is operably supported at the distal end of the outer shaft member and includes a pair of jaw members configured for treating tissue. A bushing operably couples to the inner and outer shaft members of the shaft assembly and selectively and releasably couples to the housing. The bushing includes one or more mechanical interfaces configured to engage one or more slots defined through the inner shaft member and one or more slots defined through the outer shaft member to release the inner and outer shaft members from the housing.

A surgical tool for use with a robotic system that includes a tool drive assembly that is operatively coupled to a control unit of the robotic system that is operable by inputs from an operator and is configured to robotically-generate output motions. A drive system is configured to interface with a corresponding portion of the tool drive assembly for receiving the robotically-generated output motions and applying the output motions to a drive shaft assembly which is configured to apply control motions to a surgical end effector operably coupled thereto. A manually-actuatable control system operably interfaces with the drive shaft assembly to facilitate the selective application of manually-generated control motions to the drive shaft assembly.

A surgical suturing system is disclosed. The surgical suturing system comprises a shaft, a firing drive comprising a motor, and an end effector extending distally from the shaft. The end effector comprises a needle driver configured to be actuated by the motor, wherein the needle driver is configured to drive a needle installed within the end effector. The end effector further comprises a needle track configured to guide the needle installed within the end effector through a needle firing stroke, wherein the end effector is configured to accommodate suturing needles having different sizes. The surgical suturing system further comprises a control circuit configured to sense the size of the suturing needle installed within the end effector and adjust the actuation stroke of the motor to accommodate the size of the needle installed within the end effector.

A surgical suturing system is disclosed. The surgical suturing system comprises a firing drive, an end effector, and a needle configured to be driven by said firing drive. The end effector comprises a track defined therein configured to guide the needle through a needle firing stroke. The surgical suturing system further comprises a needle driver configured to be driven by the firing drive and configured to drive the needle through the needle firing stroke.

A fastener cartridge can comprise a support portion, a tissue thickness compensator positioned relative to the support portion, and a plurality of fasteners positioned within the support portion and/or the tissue thickness compensator which can be utilized to fasten tissue. In use, the fastener cartridge can be positioned in a first jaw of a surgical fastening device, wherein a second jaw, or anvil, can be positioned opposite the first jaw. To deploy the fasteners, a staple-deploying member is advanced through the fastener cartridge to move the fasteners toward the anvil. As the fasteners are deployed, the fasteners can capture at least a portion of the tissue thickness compensator therein along with at least a portion of the tissue being fastened.

A surgical instrument system that includes a housing and a rotatable drive shaft, a motor operably coupled to the drive shaft, and a plurality of replaceable end effectors that can be connected to the housing. Each replaceable end effector includes a drive screw that is turned a fixed number of revolutions by the motor-driven rotatable drive shaft when the end effector is connected to the housing. Each end effector further comprises a firing member operably coupled with the drive screw of the end effector. The drive screw is configured to displace the firing member over a firing length as a result of the fixed number of revolutions. In certain embodiments, each replaceable end effector can include a drive screw with a thread pitch set to the firing length divided by the fixed number of revolutions.

A surgical device for clipping tissue is disclosed. The surgical device comprises a housing, a shaft extending from the housing, and a first reload releasably attachable to the shaft. The first reload comprises a first end effector and a first clip magazine including a plurality of first clips. The surgical device further comprises a second reload releasably attachable to the shaft when the first reload is not attached to the shaft. The first reload and the second reload are different sizes. The second reload comprises a second end effector and a second clip magazine including a plurality of second clips.

Various systems and methods may guide, support, and/or house instruments. One exemplary system includes a guide tube having a manipulation section and mated with rails carrying instrument control members. Moving the rails with respect to the guide tube, or another point of reference, can control movement of the manipulation section.

A stapling device including a replaceable loading unit is provided. The loading unit includes an elongated body and a stapling assembly having a first jaw and a second jaw. The first jaw of the stapling assembly includes an anvil assembly. The second jaw of the stapling assembly includes a releasably mounted cartridge assembly having a detent connection with the stapling assembly. Also provided is a tool for removing facilitating the separation of a replaceable cartridge assembly from a loading unit.

A probe insertion device for a neural probe structure with a plurality of probes to simultaneously insert the plurality of probes into a nerve includes a nerve holder to fix the nerve surrounding an outer circumference of the nerve, and a probe holder positioned outside in a radial direction of the nerve holder to fixedly support the probes surrounding a circumference of the nerve holder. The probe holder includes a plurality of sections (“probe holder sections”) arranged radially with respect to the nerve holder and moveable in a radial direction of the nerve holder, and the plurality of probe holder sections simultaneously moves the plurality of probes toward the nerve holder having fixed the nerve, so that the plurality of probes is simultaneously inserted into the nerve in a radial shape when viewed in a lengthwise direction of the nerve.
