YY/T 0644-2008 Ultrasonics-surgical systems—Measurement and declaration of the basic output characteristics
Basic Information
Scope
This standard specifies: — The main non-thermal output characteristics of ultrasonic surgical systems; Note 1: One specific parameter involved is output acoustic power. This standard only considers the low-frequency component (below 100 kHz) of the total released energy, and does not take into account the high-frequency component possibly related to cavitation generated by the tip. — The measurement methods for output characteristics; — The characteristic parameters that equipment manufacturers should disclose. Note 2: For simplicity, this standard does not consider all possible complex appearances and shapes of the treatment head tip. The interpretation of parameters and measurements is illustrated using a straight-tube-shaped tip as an example. If necessary, users of this standard can apply the basic methods described in the standard to more complex designs.
