Abstract
A frequency control method and system for an ultrasonic surgical tool. The frequency control method for an ultrasonic tool comprised: obtaining a maximum value of a phase difference between an operating voltage and an operating current of the ultrasonic surgical tool; determining whether the maximum value is less than zero, so as to obtain a first determination result; if the first determination result indicates that the maximum value is not less than zero, adjusting an operating frequency of the ultrasonic surgical tool to a frequency corresponding to the phase difference to zero; if the first determination result indicates that the maximum value is less than zero, subtracting a preset value from the maximum value to obtain a phase lock point; and adjusting, according to the phase lock point, the operating frequency of the ultrasonic tool. The frequency control method for an ultrasonic surgical tool solves a problem in which, in some situations where the phase of a self-resonant frequency does not exceed 0, ultrasonic surgical tools fail to operate normally, or operate inefficiently, thereby improving operation efficiency and stability of ultrasonic surgical tools.
