Apparatus for providing enhanced tissue fragmentation and/or hemostasis.

摘要

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.
