    Abstract: A surgical device having at least one rotary input screw in the end effector is provided. A rotary input screw can extend through a central longitudinal portion of the end effector. The end effector can include an improved closure system, firing systems, leveraging and alignment features between the staple cartridge and the surgical device, staple cartridges having multi-staple drivers, single-firing knifes and lockout/safety features for the same, and/or modified staple patterns, for example. Certain components can be 3D-printed components.

    Abstract: A surgical instrument includes an end effector, a handle assembly, and an electrode activation assembly. The end effector includes a first jaw, a second jaw, a knife, and an electrode assembly. The handle assembly includes a housing, and an arm. The arm can pivot the second jaw between the open position and the closed position. The arm can pivot relative to the housing between a first position, a second position, and a third position. The electrode activation assembly includes an activation button associated with the handle assembly, a resilient body, and a detent associated with either the housing or the arm. The activation button can activate the electrode assembly in response to the arm pivoting to the third position. The resilient body includes a first cam feature. The detent can engage the first cam feature as the arm pivots between the first position and the second position.

    Abstract: An end effector of an electrosurgical device may include a discharge port in communication with a first fluid path, an aspiration port in communication with a second fluid path, a first and second electrode, and a diverter in mechanical communication with the two electrodes. The diverter may receive, on its surface, a fluid emitted by the discharge port, and maintain a contact of the fluid with the first and second electrodes. The diverter may be further configured to prevent an aspiration, by the aspiration port, of the fluid on its surface. An electrosurgical device may include a source port in communication with a first fluid path, an evacuation port in communication with a second fluid path, a first and second electrode, and a housing. The device may include a shaft extending distally from the housing and the end effector as described above.
