Abstract: A control system for an ultrasonic hand piece is provided. The control system includes an irrigation pressure sensor configured to measure a pressure of an irrigation fluid, an ultrasonic power source configured to provide power to an ultrasonic transducer, and a controller. The controller is configured to receive a selection of an ultrasonic power modality, generate a control signal based on the selected ultrasonic power modality, provide the control signal to the ultrasonic power source, determine an irrigation flow rate from a measured irrigation pressure provided by the irrigation pressure sensor, calculate a thermal index value based on the irrigation flow rate and the selected ultrasonic power modality, and, in response to the thermal index value reaching a threshold value, adjust the control signal based on the thermal index value. The ultrasonic power modality is one of a two dimensional power modality and a three dimensional power modality.
