摘要：
An ultrasonic surgical blade includes an ultrasonic-surgical-blade body havinga longitudinal axis, a distal tip, a proximal end adapted for longitudinalultrasonic vibrational excitation, a most-distal longitudinal vibration node,a treatment portion extending from the distal tip toward the most-distallongitudinal vibration node, and a functional asymmetry. The functionalasymmetry is asymmetric about the longitudinal axis and translateslongitudinal ultrasonic vibrational movement of the proximal end into acombination of a longitudinal ultrasonic vibration and a transverse ultrasonicvibration in at least some of the treatment portion of the ultrasonic-surgical-blade body. An amplitude of the transverse ultrasonic vibration at the distaltip is less than substantially ten percent of a maximum amplitude of thetransverse ultrasonic vibration of the treatment portion of the ultrasonic-surgical-blade body. An alternate embodiment of the ultrasonic surgical bladeincludes at least one functional asymmetry and at least one balance asymmetry.
