    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 articulating ultrasonic surgical end effector for use with a hand-held surgical instrument or a robotic surgical system includes an articulation assembly, a clevis operably coupled to the articulation assembly, and a transducer assembly pivotably coupled to the clevis. The transducer assembly includes a transducer housing and an ultrasonic transducer and a waveguide disposed within the transducer housing. The waveguide is coupled to the ultrasonic transducer and extends distally from the ultrasonic transducer. The transducer assembly also includes an ultrasonic blade disposed at the distal end of the waveguide and extending from the transducer housing and a clamp arm pivotably coupled to the transducer housing and movable relative to the ultrasonic blade between an open position and a clamping position. Ultrasonic energy produced by the ultrasonic transducer is transmitted along the waveguide to the ultrasonic blade for treating tissue.

    IPC: A61B17/32

    Abstract: A surgical system includes a housing, an ultrasonic transducer supported by the housing, an end effector assembly distally-spaced from the housing, a clamp lever, and a sensor. The end effector assembly includes an ultrasonic blade operably coupled to the ultrasonic transducer for receiving ultrasonic energy produced by the ultrasonic transducer, and a jaw member pivotable relative to the blade from an open position towards a clamping position for clamping tissue between the jaw member and the blade and imparting a clamping force to the clamped tissue. The clamp lever is operably coupled to the housing and the jaw member such that actuation of the clamp lever relative to the housing pivots the jaw member towards the blade. The sensor is configured to sense whether the clamp lever is sufficiently actuated so as to impart the clamping force to the clamped tissue.

    IPC: A61B18/02

    Abstract: A surgical system includes a surgical instrument and a cooling module operably coupled to the surgical instrument. The surgical instrument includes a housing and an elongated portion extending from the housing and supporting an end effector. The cooling module includes a fluid reservoir retaining a cooling fluid, a thermoelectric cooler, and a pump assembly. The thermoelectric cooler has a first portion thermally coupled to the fluid reservoir and a second portion including a plurality of fins dissipating heat therefrom. The pump assembly is configured to supply the cooling fluid through at least a portion of the surgical instrument and back to the fluid reservoir, thereby defining a flow path to cool the end effector of the surgical instrument.

    Abstract: An ultrasonic surgical device includes a power source configured to generate power, an ultrasonic transducer electrically coupled to the power source and generating ultrasonic motion in response to the generated power, a sensor sensing current of the generated power supplied to the ultrasonic transducer, an ultrasonic probe mechanically couplable to the ultrasonic transducer, and a controller that receive a sensed current from the sensor, performs a frequency response analysis based on the sensed current, calculates a first resonant frequency and a first anti-resonant frequency of the transducer prior to coupling the ultrasonic probe based on the frequency response analysis, calculates a second resonant and second anti-resonant frequencies of the transducer based on the frequency response analysis prior to determining coupling to the ultrasonic transducer, and determines whether the ultrasonic probe is mechanically coupled to the ultrasonic transducer based on the first and second resonant and anti-resonant frequencies.
