Abstract: An electrosurgical flux supply unit includes a first terminal configured to deliver a first electrical flux, the first terminal being configured to be electrically coupled with a first electrode of a first electrosurgical instrument, a second terminal configured to receive a second electrical flux; the second terminal being configured to be electrically coupled with a second electrode of the first electrosurgical instrument, and an electrical switching mechanism selectively configurable between a first state and a second state. In the first state, the electrical switching mechanism electrically couples the first electrode with the first terminal and, in the second state, the electrical switching mechanism electrically isolates the first electrode from the first terminal. The electrosurgical flux supply unit is configured to maintain the electrical coupling of the second terminal with the second electrode in both the first state and the second state of the electrical switching mechanism.

Abstract: An electrosurgical instrument may comprise a pair of jaw members configured to move between an open position and a closed position. In the closed position, the pair of jaw members may be configured to exert a gripping force on material placed between working surfaces of the pair of jaw members. A first jaw member of the pair of jaw members may comprise a first electrode, and a second jaw member of the pair of jaw members may comprise a second electrode and a third electrode.

Abstract: An electrosurgical end effector for a surgical tool to perform teleoperated surgical operations. The electrosurgical end effector comprises a first end effector jaw; a second end effector jaw coupled to the first end effector jaw; and a coupling pin configured to rotatingly couple the first end effector jaw to the second end effector jaw so as to cooperatively rotate open and close about an axis of rotation. The electrosurgical end effector further comprises an actuation mechanism coupled to an end of the first end effector jaw to rotate the first end effector jaw about the coupling pin; an otomy feature coupled to the second end effector jaw; and a first electrical conductor to electrically couple the otomy feature to a generator. In one embodiment, the otomy feature is electrically activated by contact with a cam portion of the first end effector jaw, when opened beyond a predetermined jaw angle.
