    摘要: 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 thereby causing current to flow through the tissue and, as a result, generate heat within the tissue. The surgical instrument can further comprise a fluid circulatory system embedded within at least a portion the end effector wherein, in at least one embodiment, the fluid can be dispensed from the fluid circulatory system and onto the jaws of the end effector and/or the tissue positioned between the jaws.

    摘要: Various embodiments are directed to an apparatus, system, and method for driving an end effector coupled to an ultrasonic transducer. The method comprises generating a first ultrasonic drive signal by a generator coupled to an ultrasonic drive system, actuating the ultrasonic transducer with the first ultrasonic drive signal, generating a second ultrasonic drive signal by the generator, and actuating the ultrasonic transducer with the second ultrasonic drive signal. The first drive signal is different from the second drive signal. The first and second drive signals define a step function waveform. The apparatus comprises a generator configured to couple to an ultrasonic instrument. The system comprises a generator coupled to an ultrasonic instrument. The ultrasonic instrument comprises an ultrasonic drive system comprising an ultrasonic transducer coupled to a waveguide and an end effector coupled to the waveguide, and wherein the ultrasonic drive system configured to resonates at a resonant frequency.
