摘要: An ultrasonic surgical system includes an ultrasonic instrument configured to seal a vessel and including an ultrasonically-activatable blade and a jaw member pivotably movable with respect to the blade, an endoscope configured to capture video data of a surgical site including the blade and the jaw member, and a processor connected to the endoscope. The processor is configured to process the video data to determine an angle between the blade and the jaw member, determine a desired energy level based on the angle, and provide the desired ultrasonic energy as a feedback to the ultrasonic instrument. The ultrasonic instrument performs a closed-loop control to maintain the desired ultrasonic energy.

摘要: An ultrasonic motion generator includes a non-resonant inverter, an ultrasonic transducer, and a comparator. The non-resonant inverter inverts direct current (DC) to alternating current (AC) having a first frequency. The ultrasonic transducer is electrically coupled with the non-resonant inverter and generates an ultrasonic motion based on the inverted AC. The comparator automatically detects a deviation of the first frequency from a resonant frequency of the ultrasonic transducer based on motion current passing through the ultrasonic transducer and generates an output signal based on the deviation to drive the non-resonant inverter.

摘要: A surgical system includes an ultrasonic generator configured to provide an ultrasonic drive signal, an ultrasonic transducer coupled to the ultrasonic generator to receive the drive signal and produce mechanical ultrasonic energy, an electrosurgical generator configured to output three-phase RF energy, and an end effector assembly. The end effector assembly includes an ultrasonic blade coupled to the transducer to supply the mechanical ultrasonic energy to tissue to treat tissue. At least a portion of the ultrasonic blade defines a first electrode; second and third electrodes are also provided. The first and second electrodes, the first and third electrodes, and the second and third electrodes are electrically coupled to the electrosurgical generator and configured to conduct the first, second, and third phases, respectively, of the three-phase RF energy therebetween and through tissue to at least one of treat or interrogate tissue.

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.
