Abstract: An adapter configured to receive a drive signal from a control console and to provide the drive signal to an ultrasonic surgical handpiece. The adapter includes a receptacle for receiving the ultrasonic surgical handpiece and providing the drive signal to the ultrasonic surgical handpiece. The adapter includes a module for detecting a presence of the ultrasonic surgical handpiece and a connector to be inserted into a receptacle of the control console to receive the drive signal from the control console. The adapter includes a radio-frequency identification device coupled to the connector and to a memory storing a maximum and minimum frequency for driving the ultrasonic surgical handpiece. The radio-frequency identification device transmits the maximum and minimum frequency from the memory to the control console via the connector using an RFID protocol in response to the module detecting the presence of the ultrasonic surgical handpiece.

Abstract: A control console for a powered surgical tool. The console includes a transformer that supplies the drive signal to the surgical tool. A linear amplifier with active resistors selectively ties the ends of the transformer primary winding between ground and the open circuit state. Feedback voltages from the transformer windings regulate the resistances of the active resistors.

Abstract: An ultrasonic tool system with a console and a tip that has a distal end that when vibrated vibrates both longitudinally and torsionally. The console applies a drive signal to the drivers that vibrate the tip that is at a longitudinal mechanical cancellation frequency. Consequently, when the tip is vibrated, at the distal end the longitudinal component of a first resonant mode of the tip cancel out the longitudinal component of the second resonant move of the tip so the distal end of the tip engages in vibrations that substantially torsional and only minimally longitudinal.

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: An ultrasonic surgical tool system for actuating a handpiece with a tip. The frequency of the drive signal applied to the handpiece drivers is a function of the equivalent of current through the mechanical components of the handpiece and tip and the frequency responsiveness of these components.

Abstract: An ultrasonic surgical tool system with a tip capable of simultaneously vibrating in plural modes. The system includes a console capable of supplying a drive signal to the tip that includes plural components. Each component has a frequency characteristic that is based in part on the equivalent of current through the mechanical components of the tip. The frequency components are different from each other. Based on the application of drive signal the tip undergoes non-linear vibrations.

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.

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.
