Abstract
An ultrasonic surgical cutting instrument includes a handpiece containing an ultrasonic generator. A hollow cutting probe is connected to the handpiece and is longitudinally moved at ultrasonic frequency when the generator is energized. The hollow probe has a cutting edge or edges formed thereon. One embodiment has a side cutting edge for side cutting action of skin, tissue, or bone. Other embodiments have a cutting edge formed on the tip of the probe. The hollow probe allows cut tissue or bone to be removed from the operative site by a vacuum applied thereto. The hollow probe also allows an irrigating fluid to be introduced to the operative site.
