Title:
METHOD FOR CONTROLLING DYNAMIC BRANCH CURRENT OF ULTRASONIC TRANSDUCER, AND ULTRASONIC SURGICAL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/022268
Kind Code:
A1
Abstract:
The present application relates to a method and apparatus for controlling a dynamic branch current of an ultrasonic transducer, an ultrasonic surgical system, a computer device, and a storage medium. The method comprises: acquiring a first driving signal inputted into an ultrasonic transducer, the first driving signal comprising a first driving current, a first driving voltage, and a first driving frequency; acquiring the static capacitance of the ultrasonic transducer; and adjusting the first driving signal according to the first driving current, the first driving voltage, the first driving frequency, and the static capacitance, so as to control a dynamic branch current by adjusting the first driving signal. According to the method, precise control of the dynamic branch current of the ultrasonic transducer can be realized without a matched inductor, and the surgical effect consistency and stability of an ultrasonic surgical system comprising the ultrasonic transducer are improved.
