Abstract: 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.

Abstract: A surgical instrument includes a housing having an elongated body extending distally therefrom. The elongated body defines a first articulating portion and a second articulating portion. The elongated body defines a lumen therein. An end effector is supported at a distal end portion of the elongated body. A flexible waveguide extends through the lumen of the elongated body. A proximal end portion of the flexible waveguide connects to an ultrasonic transducer. A distal end portion of the flexible waveguide is connected with the end effector. the flexible waveguide defines a first articulating portion having a narrower thickness than a thickness of other portions of the flexible waveguide and a second articulating portion having a narrower thickness than a thickness of other portions of the flexible waveguide.

Abstract: A surgical instrument end effector assembly includes a first jaw member defining an insulative tissue-contacting surface and first and second electrically-conductive tissue-contacting surfaces disposed on either side of the insulative surface. A second jaw member of the end effector assembly includes an ultrasonic blade body positioned to oppose the insulative surface of the first jaw member, and first and second electrically-conductive tissue-contacting surfaces disposed on either side of the ultrasonic blade body and positioned to oppose the first and second electrically-conductive surfaces, respectively, of the first jaw member. The first jaw member is movable relative to the second jaw member between a spaced-apart position and an approximated position to grasp tissue therebetween. The first and second electrically-conductive surfaces of the second jaw member are movable, independent of the first jaw member, relative to the first jaw member and the ultrasonic blade body between a retracted position and an extended position.

Abstract: An ultrasonic surgical instrument includes an ultrasonic waveguide defining a blade at a distal end thereof, and a jaw member. The ultrasonic waveguide is configured to transmit ultrasonic energy therealong to the blade for treating tissue therewith. The jaw member is movable relative to the blade from a spaced-apart position to an approximated position. The jaw member has a more-rigid structural body and a more-compliant jaw liner engaged with the structural body. The jaw liner defines a tissue grasping surface having a configuration at least partially complementary to a configuration of a tissue grasping surface of the blade such that, in the approximated position, the tissue grasping surfaces are configured to grasp tissue therebetween with the at least partially complementary configurations of the first and second tissue grasping surfaces facilitating tissue grasping.

Abstract: An end effector assembly of a surgical instrument includes an ultrasonic blade. A jaw member is movable relative to the ultrasonic blade from a spaced-apart position to an approximated position. The jaw member includes a structural body. The structural body defines a first side facing the ultrasonic blade and a second side facing away from the ultrasonic blade. A jaw liner is engaged with the first side of the structural body such that the jaw liner contacts the ultrasonic blade when the jaw member is in the approximated position. An electrode is engaged with the second side of the structural body. The electrode is adapted to connect to a source of electrosurgical energy. The electrode defines a first portion and a second portion. The first portion of the electrode is in contact with the structural body and the second portion of the electrode tapers to a pointed edge.
