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.

Surgical instruments and assemblies for sealing and cutting tissue monitor jaw angle and/or jaw clamping force to provide feedback to an operator of the surgical instrument indicative of whether the tissue is suitable clamped for sealing and/or cutting. A surgical instrument or assembly includes a jaw operable to clamp tissue, a sealing mechanism, a cutting mechanism, an actuation monitoring assembly, and a feedback assembly. The actuation monitoring assembly monitors jaw angle and/or clamping force. The feedback assembly outputs feedback to the operator, based on the jaw angle and/or clamping force, as to whether the current clamping angle and/or jaw angle is suitable for sealing and/or clamping tissue.
