A system is disclosed. The system can comprise an end effector configured to receive a compatible replaceable staple cartridge, wherein the end effector comprises a first outer surface, and wherein a classifying identification of the end effector is inscribed on the first outer surface. The system can also comprise the compatible replaceable staple cartridge comprising a second outer surface, wherein a classifying identification of the compatible replaceable staple cartridge is inscribed on the second outer surface. The classifying identification of the compatible replaceable staple cartridge can correspond to the classifying identification of the end effector.

A surgical stapling device includes a housing assembly that is coupled to a tool assembly by a flexible elongate body that having an outer tube, a middle tube, and an inner cable. Each of the outer tube and the inner cable has a proximal end portion fixedly connected to the housing assembly and a distal end portion that is fixedly connected to the tool assembly. The middle tube is positioned within the outer tube about the inner cable and is movable from a retracted position to an advanced position to operate the tool assembly.

An endoscope treatment tool includes: a distal end part provided with an openable and closable grip part; a bendable part provided adjacent to the distal end part and being bendable; an operating part into which an operation of closing the grip part and an operation of bending the bendable part are input; and an operation wire that transmits the operations at the operating part respectively to the grip part and the bendable part, and the operating part includes an operating part body that movably holds a wire holding part to which the operation wire is connected, and an operation handle that moves the wire holding part, and has a friction adjusting mechanism that increases a frictional force locking the wire holding part to correspond to an increase in a pulled amount of the operation wire caused by the wire holding part interlocked with an operation of the operation handle.

A system for stapling tissue is disclosed. The system can include a channel and a compatible staple cartridge comprising a plurality of staples. The channel and the compatible staple cartridge comprise mating or cooperating alignment features for permitting complete insertion of the compatible staple cartridge and for preventing an incompatible staple cartridge from being completely inserted in the channel.

Medical devices including a housing, an actuator, a body having a passageway extending through the body, a drive shaft extending through the passageway, and a clip coupled to the body and the drive shaft to fix the body relative to the drive shaft. The medical device further including features to couple the clip to at least one of the body and/or the drive shaft such that back out of the clip is inhibited.

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 system is disclosed which comprises a distal end and a staple cartridge assembly comprising staples removably stored therein. The instrument system further comprises a firing drive including an electric motor and a firing member operably couplable with the electric motor. The electric motor is operable to advance the firing member toward the distal end during a staple firing stroke to eject the staples from the staple cartridge. The electric motor is operable to retract the firing member away from the distal end during a retraction stroke. The surgical instrument system further comprises a manually-operated bailout mechanism operable to perform the retraction stroke in lieu of the electric motor, a controller, and a display in communication with the controller. The controller is configured to display the progress of the retraction stroke when the firing member is being manually retracted by the bailout mechanism.

Forceps can include a drive pin, an outer tube, a first jaw, a second jaw, and an inner shaft. The outer tube can extend along a longitudinal axis. The first jaw can be pivotably connected to the outer tube. The first jaw can include a first flange that can be located at a proximal portion of the first jaw. The first flange can include a first chamfered edge configured to limit extension of the first flange laterally beyond an outer surface of the outer tube when the first jaw is in a closed position. The inner shaft can be located within the outer tube and can extend along the longitudinal axis.

Forceps can include an outer tube, a first jaw, a second jaw, and an inner tube. The outer tube can extend along a longitudinal axis and can include a pair of outer arms extending from a distal portion of the outer tube. The first jaw can be pivotably connected to the outer tube and the first jaw can include a first flange and a second flange each located at a proximal portion of the first jaw. The first flange and the second flange can each include a proximal portion extending outward of the outer tube when the jaws are in an open position. The proximal portions can be shaped to limit extension of the proximal portions laterally beyond the outer arms.

Forceps with improved actuation include a housing and a body that is longitudinally slidable relative to the housing. The body having a peripheral flange extending outward towards the housing. A trigger includes an actuation surface configured to receive a force input from a user. The trigger further including at least one arm configured to transfer the received force input to the body. To inhibit lateral splaying of the at least one arm when the trigger is actuated, the housing includes a first control surface, such as a rib proximate the arm.
