摘      要：In response to the ultrasonic scalpels with the vibrational modal coupling which leads to a decrease in efficiency,an ultrasonic scalpel based on fusiform phononic crystals(PnCs)is *** accurate theoretical model is constructed,which is mainly composed of electromechanical equivalent circuit models to analyze the frequency response function and the frequency response curves of the *** band gaps exist in the fusiform PnCs owing to the periodic constraint,which can suppress the corresponding vibrational *** vibration characteristics(vibration mode,frequency,and displacement distribution)of the ultrasonic scalpel are analyzed,and the validity of the electromechanical equivalent circuit method is *** results indicate that other vibration modes near the working frequency can be *** addition,blades based on fusiform PnCs have a function akin to that of the horn,which enables displacement amplification.
