Abstract: Systems and methods for controlling vibrations of a tip of an ultrasonic instrument. A maximum ultrasonic energy level for the ultrasonic instrument is determined, and a minimum ultrasonic energy level for the ultrasonic instrument is determined based on the maximum ultrasonic energy level. An AC drive signal is then sourced to the ultrasonic instrument that induces ultrasonic energy in the tip of the ultrasonic instrument including several ultrasonic energy pulses. The ultrasonic energy pulses peak at the determined maximum ultrasonic energy level and are interspaced by significant periods at the determined minimum ultrasonic energy level.

Abstract: Systems and methods for controlling vibrations of an ultrasonic handpiece generate an AC drive signal applied to a transducer of the ultrasonic handpiece to vibrate a tip of the ultrasonic handpiece. A property relating to a stiffness of tissue being contacted by the vibrating tip is determined based on a measured voltage and a measured current of the AC drive signal. A target displacement for the tip is determined based on the tissue property, and the AC drive signal is adjusted to achieve the determined target displacement.

Abstract: Systems and methods for probing patient issue using an ultrasonic surgical aspirator including a tip for treating patient tissue and a control console coupled to the handpiece. The control console sources an AC drive signal to the ultrasonic handpiece that causes the tip to vibrate against the patient tissue. The AC drive signal includes a first component at a resonant frequency of the ultrasonic handpiece and a second component at a probing frequency less than the resonant frequency. The control console measures a voltage and current of the AC drive signal, calculates a resistance associated with the ultrasonic handpiece based on the measured voltage and current, and then provides at least one of an audible, visual, or tactile indication based on the calculated resistance.
