Abstract:
1. A generator to communicate a drive signal to a surgical device, the generator comprising: a power amplifier to receive a time-varying drive signal waveform, the drive signal waveform generated by a digital-to-analog conversion of at least a portion of a plurality of drive signal waveform samples, an output of the power amplifier for generating a drive signal, the drive signal comprising one of: a first drive signal to be communicated to an ultrasonic surgical device, a second drive signal to be communicated to an electrosurgical device; a sampling circuit to generate samples of current and voltage of the drive signal when the drive signal is communicated to the surgical device, generation of the samples synchronized with the digital-to-analog conversion of the drive signal waveform samples such that, for each digital-to-analog conversion of a drive signal waveform sample, the sampling circuit generates a corresponding set of current and voltage samples; and at least one programmable device programmed to, for each drive signal waveform sample and corresponding set of current and voltage samples:
