  • Patent number: 11090104
    Abstract: A control circuit configured to receive a control signal that defines a first phase and a second phase from a surgical generator. The control circuit may include a first resistor, a second resistor in parallel with the first resistor, and a switch in series with the second resistor. The switch may be configured to transition between an open state and a closed state corresponding to an operational mode of a surgical instrument. In the first phase of the control signal, the control circuit is configured to communicate surgical instrument information to the surgical generator. In the second phase of the control signal and in the open state of the switch, the control circuit is configured to provide a first output. In the second phase of the control signal and in the closed state of the switch, the control circuit is configured to provide a second output.

  • Patent number: 10263171
    Abstract: 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.

  • Patent number: 10201382
    Abstract: 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.
