Abstract: An apparatus having a vibratable tip (22) for ultrasonically disintegrating tissue in a surgical procedure and for aspirating the disintegrated tissue and fluid away from the surgical site (12) through an opening (24) in the tip. A connection (42) to the electrosurgical unit provides for delivery of RF cutting current, RF coagulating current or a blend thereof to the tip so that electrosurgical procedures can be conducted separately or simultaneously with ultrasonic aspiration through the tip. It thus is now possible, for example, to electrocauterize simultaneously with ultrasonic fragmentation with a single handheld surgical device. The simultaneous delivery of ultrasonic vibrations and RF current to the tip also has been found to increase the tissue fragementation rate.

Abstract: An ultrasonic resonant vibrator comprising an ultrasonic vibration magnetostrictive transducer (1) and a resonant member (2,3) having a proximal end and a distal end for transmitting ultrasonic vibrations to an operating member (3) which is part of the resonant structure. The vibrator comprises an integral substantially rigid column having a central axis with fins extending radially relative to said axis and having a longitudinal hole defining a tunnel (8) centered along the central axis, wherein at least part of the resonant member is located within the tunnel; and a surgical handpiece incorporating such a vibrator.

Abstract: An ultrasonic oscillator drives a tool at a set frequency. An amplitude control runs the oscillator to set the vibration level. A frequency regulator joins the amplitude and the oscillator. A control feedback loop, in the frequency regulator, keeps handpiece linear dynamics. An operational transconductance amplifier, in the oscillator, governs gain of the loop. A circuit connects to the control to retard the rate of current application over time to the amplifier. The circuit has switching to either retard the rate or reset for start up. The amplifier is a current output device with current directly proportional to the bias current and input voltage with bias as gain change for the loop. The circuit limits the bias to the amplifier to modify frequency response and output current. A capacitor delays application of the bias to the amplifier. Replaceable tools of various lengths or shapes positioned along an axis vibrate for surgery at the frequency and a wave length. Tools longer than one wavelength and of configurations tuned to oscillate around the frequency resonate as a function of their material, length and configuration. A flue surrounds the tool and has a hollow elongate semi rigid central body about an axis with a funnel, at one end thereof and a nozzle, at the other to direct annular irrigant/coolant flow therethrough. The funnel and nozzle are resilient. Reinforcing ridges, inside the nozzle, act to maintain concentricity between the flue and nozzle tip and channel irrigant thereabout.
