Abstract

Defines the essential non-thermal characteristics of ultrasonic surgical units, measurement methods of these output characteristics and those characteristics for declaration by the manufacturers of the equipment. Applicable to equipment which meets the requirements of ultrasonic surgical systems operating in the frequency range 20 kHz to 60 kHz; ultrasonic surgical systems, whose use is the fragmentation or cutting of human tissue, whether or not those effects are delivered in conjunction with tissue removal or coagulation and ultrasonic surgical systems, in which an acoustic wave is conducted by means of a specifically designed wave guide to deliver energy to the surgical site.
