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