    摘要: An ultrasonic surgical system includes an ultrasonic generator configured to provide an electrical drive signal, an ultrasonic transducer configured to receive the electrical drive signal and to produce ultrasonic mechanical motion in response thereto, and a blade coupled to the ultrasonic transducer and configured to receive the ultrasonic mechanical motion from the ultrasonic transducer for treating tissue in contact therewith. The ultrasonic transducer defines a saturation point and the ultrasonic generator is configured to drive the ultrasonic transducer substantially at the saturation point such that the ultrasonic mechanical motion produced by the ultrasonic transducer is substantially equal to a maximum ultrasonic mechanical motion of the ultrasonic transducer.

    摘要: A surgical instrument includes a handle assembly, an elongate member, and a motor assembly. The elongate member extends from the handle assembly and defines a longitudinal axis of the surgical instrument. The motor assembly is disposed within the handle assembly and is configured to rotate the elongate member about the longitudinal axis relative to that handle assembly in response to sensed movement of the handle assembly about the longitudinal axis.

    摘要: A medical device for treating and analyzing tissue includes a plasma applicator having a housing. The housing includes a substantially tubular shape and defines a lumen therethrough. The lumen is in fluid communication with an ionizable media source configured to supply ionizable media thereto. The applicator also includes one or more electrodes coupled to the housing. The electrodes are adapted to couple to a power source configured to energize the electrodes to ignite the ionizable media to form a plasma plume for treating tissue. The device also includes an effluent-collection attachment coupled to the plasma applicator. The effluent-collection attachment is configured to collect a portion of a plasma effluent.

    摘要: An electrosurgical smoke evacuation pencil includes a handle housing having a proximal end portion and a distal end portion, the handle housing defining a lumen therethrough, a nozzle in fluid communication with the lumen, a pressure sensor configured to sense a vacuum pressure at the nozzle, a connector coupled to the distal end portion of the handle housing, the connector configured to couple to a suction source, and an electrode configured to couple to a source of electrosurgical energy.
