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