摘要： An electrosurgical instrument comprising an end effector is disclosed. The end effector comprises a first jaw and a second jaw. At least one of the first jaw and the second jaw is movable to transition the end effector from an open configuration to a closed configuration to grasp tissue therebetween. The second jaw comprises linear portions cooperating to form an angular profile and a treatment surface comprising segments extending along the angular profile. The segments comprise different geometries and different conductivities. The segments are configured to produce variable energy densities along the treatment surface.

摘要： An apparatus includes a body assembly with a handle (300) and a shaft portion, an end effector with a staple deck fixed to the shaft portion, an anvil, and a firing assembly. The end effector further includes a trocar and a staple driver both configured to actuate relative to the staple deck. The staple driver can actuate a distance between an unfired position and a fired position. The trocar can couple with the anvil to define a gap distance. The firing assembly includes a trigger (304) pivotably coupled with the body assembly via a first pivot (305), a driver actuator (316) configured to actuate the staple driver, and a linkage assembly (320) pivotably coupled with the trigger via a second pivot (330) and the driver actuator. Where the second pivot is proximal relative to the first pivot. The linkage assembly can drive the driver actuator is response to the trigger pivoting about the first pivot.

摘要： A surgical system comprising a generator and a surgical instrument configured to receive power from the generator is disclosed. The surgical instrument comprises a housing, a shaft defining a longitudinal axis, an end effector, and an internal charge accumulator. The housing comprises a motor. The end effector is operably responsive to actuations from the electric motor, transitionable between an open and closed configuration, and rotatable about an articulation axis transverse to the longitudinal axis. The generator is incapable of supplying a sufficient power directly to the motor to perform the actuations. The internal charge accumulator is in electric communication with the generator and supplies power to the motor. The internal charge accumulator is chargeable by the generator to a threshold value at a charge rate dependent on a charge level of the internal charge accumulator. The charge rate is independent of a charge expenditure by the surgical instrument.

摘要： A surgical instrument that includes a surgical end effector that is articulatable relative to a proximal shaft segment of the surgical instrument. The surgical end effector is attached to the proximal shaft segment by an articulation joint that comprises a plurality of movably interconnected links that interface with a centrally disposed drive member to apply articulation motions thereto and which serve to provide improved lateral stability to the articulation joint.

摘要： A surgical instrument comprising an end effector including a proximal end, a distal end, a first jaw, and a second jaw is disclosed. The first jaw comprises a first electrode. The second jaw comprises a second electrode and a monopolar electrode centrally disposed down a length of the end effector. The first electrode and the second electrode cooperate to deliver bipolar energy to the tissue in a bipolar cycle. The monopolar electrode comprises a wedge shape that graduates in width along the length of the end effector. The monopolar electrode is electrically isolated from the first and second electrodes. The monopolar electrode is configured to employ monopolar energy to cut the tissue in a monopolar cycle.
