Abstract:
1. An electrosurgical instrument, comprising: a handle; an elongate shaft extending distally from said handle; an end effector extending distally from said elongate shaft, comprising: an axially movable member translatable during an operational stroke to move said first jaw member to said closed configuration, said tissue-cutting element positioned at a distal portion of said axially movable member; a trigger system coupled to said axially movable member, wherein said trigger system is movable during said operational stroke to advance said tissue-cutting element through a first tissue zone of said captured tissue, wherein said trigger system is movable during said operational stroke to advance said tissue-cutting element through a second tissue zone of said captured tissue, wherein said first tissue zone is proximal to said second tissue zone, wherein said trigger system is configured to provide a first trigger feedback signal during said operational stroke, and wherein said trigger system is configured to provide a second trigger feedback signal during said operational stroke; a first pacing indicator configured to provide a first pacing feedback signal corresponding to a first impedance level of said first tissue zone; and a second pacing indicator configured to provide a second pacing feedback signal corresponding to a second impedance level of said second tissue zone, wherein said first pacing feedback signal is configured to signal a user to advance said tissue-cutting element through said first tissue zone until said first trigger feedback signal is transmitted, and wherein said second pacing feedback signal is configured to signal the user to advance said tissue-cutting element through said second tissue zone until said second trigger feedback signal is transmitted.
