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.

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.

A surgical instrument includes an instrument shaft, two instrument branches that can be positioned relatively to one another in a working position and a rest position, a handle element on which an operating element is movably arranged for positioning the instrument branches, and a coupling mechanism having a translating unit that converts a movement of the operating element, non-linearly, into a relative movement of at least one of the two instrument branches. The coupling mechanism includes at least one bias element that biases the mechanism into the rest position and/or into the working position of the instrument branches.

A handle assembly of a surgical instrument includes a housing, a trigger pivotably coupled to the housing, a drive bar disposed within the housing and operably coupled to the trigger such that pivoting of the trigger translates the drive bar, and a bilateral spring disposed within the housing and operably coupled to at least one of the trigger or the drive bar. The trigger is movable relative to the housing between first, second, and third positions wherein the first position is disposed between the second and third positions. The bilateral spring includes a compression spring configured to compress upon movement of the trigger in a first direction from the first position towards the second position to establish a first bias, and to compress upon movement of the trigger in a second, opposite direction from the first position towards the third position to establish a second bias.

A surgical stapling attachment configured to clamp, staple, and cut tissue is disclosed. The surgical stapling attachment comprises an attachment portion, a shaft assembly, an articulation joint, and an end effector assembly. The end effector assembly comprises a firing system configured to cut tissue only after the tissue has been stapled.

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.

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.

An electrosurgical instrument includes a shaft assembly, an end effector, an input actuator, a biasing feature, an end of stroke feature, a first clamp closure sensor, a second clamp closure sensor, and a control unit. The end effector includes an energized feature, a first jaw, and a second jaw. The first clamp closure sensor is configured to produce first sensor information relating to movement of the input actuator. The second clamp closure sensor is configured to produce second sensor information relating to deflection of the biasing feature in response to a tissue load force between the first and second jaws. Based on each of the first and second sensor information, the control unit is configured to determine the tissue load force exerted on the end effector, and a position of one of the first and second jaws relative to the other of the first and second jaws.

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 endoscope treatment tool includes: a distal end part; an operating part into which an operation to the distal end part is input; and a soft portion that connects the distal end part and the operating part, and the operating part includes a fixing unit that attaches the operating part to an endoscope, and an operating part body that is capable of moving forward and backward with respect to the fixing unit and that is rotatable along a plane orthogonal to the forward and backward movement direction, and has a friction mechanism that generates a first frictional force between the fixing unit and the operating part body in a rotation direction of the operating part body and that generates a second frictional force between the fixing unit and the operating part body in the forward and backward movement direction, which is different from the first frictional force.
