  • Patent number: 8663220
    Abstract: In one general aspect, various embodiments are directed to a surgical instrument that can supply mechanical energy and electrical energy to an end effector of the surgical instrument. The surgical instrument may be operated in a first operating mode in which a transducer of the surgical instrument produces mechanical energy, or vibrations, that are transmitted to the end effector and a second operating mode in which electrical energy, or current, can flow through the end effector to perform electrosurgery. In another general aspect, the surgical instrument may comprise a clamp, or jaw, which can be moved into a closed position to hold tissue against a waveguide, or blade, of the end effector. In the second operating mode of the surgical instrument, current can flow from a power source, through the waveguide, and return to the power source through a path comprising the jaw.

  • Publication number: 20110306965
    Abstract: An electrosurgical surgical instrument can comprise a handle and an end effector, wherein the end effector can comprise first and second jaws which can be opened and closed in order to capture tissue therebetween. In various embodiments, the first and second jaws can comprise one or more electrodes configured to apply a voltage across the tissue, wherein one or both of the first and second jaws can include a plurality of electrodes each comprised of a positive temperature coefficient material having a different switching temperature. The electrical resistances of the electrodes can increase significantly once the temperature of the electrodes exceed their switching temperatures and, owing to the increased electrical resistance, the flow of current through the electrodes can be reduced and/or prevented. In various circumstances, the different switching temperatures of the electrodes can allow some of the electrodes to switch off before the other electrodes.
