摘要： A method for determining motional branch current in an ultrasonic transducer of an ultrasonic surgical device over multiple frequencies of a transducer drive signal. The method may comprise, at each of a plurality of frequencies of the transducer drive signal, oversampling a current and voltage of the transducer drive signal, receiving, by a processor, the current and voltage samples, and determining, by the processor, the motional branch current based on the current and voltage samples, a static capacitance of the ultrasonic transducer and the frequency of the transducer drive signal.

摘要： A method for controlling a waveform shape of a motional branch current in an ultrasonic transducer of a surgical device. The method may comprise generating a transducer drive signal by selectively recalling, using a direct digital synthesis (DDS) algorithm, drive signal waveform samples stored in a look-up table (LUT), generating samples of current and voltage of the transducer drive signal when the transducer drive signal is communicated to the surgical device, determining samples of the motional branch current based on the current and voltage samples, a static capacitance of the ultrasonic transducer and a frequency of the transducer drive signal, comparing each sample of the motional branch current to a respective target sample of a target waveform to determine an error amplitude, and modifying the drive signal waveform samples stored in the LUT such that an amplitude error between subsequent samples of the motional branch current and respective target samples is reduced.

摘要： A surgical generator is disclosed including an ultrasonic generator module to provide at an ultrasonic drive signal for driving an ultrasonic surgical device and an electrosurgical generator module to provice an electrosurgical drive signal for driving an electrosurgical device. At least one of providing the ultrasonic drive signal or providing the electrosurgical drive signal includes recalling a waveform sample from a look-up table (LUT), modifying the waveform sample to generate a modified waveform based on voltage and current feedback information to pre-distort the waveform sample on a dynamic ongoing basis, indexing each stored voltage and current feedback data pair based on a corresponding LUT sample that was output when the voltage and current feedback data pair was acquired, synchronizing the LUT sample and the voltage and current feedback data pair to correct timing and stability of the pre-distorted waveform sample, and providing the modified waveform to an output stage.
