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.
