Cutting mechanisms for surgical end effector assemblies, instruments, and systems

摘要: An end effector assembly for a surgical instrument includes first and second jaw members each including housing, an electrically-conductive tissue-treatment plate, longitudinally-extending channel. The and/or member is movable relative to the other between spaced-apart position approximated position. A cutting mechanism disposed at least partially within member. may include inflatable bladder, fluid line coupled knife bladder. alternatively line, knife, sealing that defines variable-volume sealed chamber channel of one electromagnet, electrical wire operably electromagnet.
