    摘要: A method for sealing a vessel includes supplying electrical energy to an ultrasonic surgical instrument having an end effector and a transducer coupled to the end effector, when the end effector is grasping a vessel, sensing parameters of the vessel when the end effector achieves a predetermined velocity, estimating a size of the vessel based on the sensed parameters, controlling the electrical energy based on maintaining a predetermined initial heating rate of heating the vessel until a predetermined amount of energy corresponding to the estimated size of the vessel has been delivered, and controlling the electrical energy based on a predetermined heating rate curve of heating the vessel after the predetermined amount of energy corresponding to the estimated size of the vessel has been delivered.

    摘要: An ultrasonic surgical system includes an ultrasonic generator configured to provide an ultrasonic drive signal, and an ultrasonic transducer electrically coupled to the ultrasonic generator to receive the ultrasonic drive signal therefrom and configured, in response to the received ultrasonic drive signal, to produce a mechanical motion. The ultrasonic surgical system further includes a sensor configured to sense a frequency and a magnitude of the mechanical motion, and a controller configured to receive a target mechanical motion to be produced by the ultrasonic transducer and control the ultrasonic drive signal so that a frequency of the ultrasonic drive signal falls within a frequency range around a resonant frequency of the ultrasonic transducer, the frequency range corresponding to the target mechanical motion produced by the ultrasonic transducer.

    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.
