Title:
ULTRASOUND-BASED RAPID PATHOLOGICAL TISSUE PROCESSING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/174661
Kind Code:
A1
Abstract:
An ultrasound-based rapid pathological tissue processing method and device. The method comprises: obtaining a vibration signal acquired by a piezoelectric thin film sensor (8) within a preset period (S201), the piezoelectric film sensor (8) being provided in a processing cylinder (2) of the pathological tissue processing device, and the vibration signal being a vibration signal of the processing cylinder (2) acquired by the piezoelectric thin film sensor (8); determining, on the basis of the vibration signal, a first vibration signal corresponding to a first resonant frequency point (S202), the first resonant frequency point being the resonant frequency of an ultrasonic wave emitted by an ultrasonic transducer (4) of the pathological tissue processing device; determining an amplitude characterization value of the first resonant frequency point according to the first vibration signal (S203); determining a duty cycle adjustment value of the ultrasonic transducer (4) on the basis of the amplitude characterization value and a preset optimal amplitude characterization value (S204); and under the condition that the amplitude characterization value does not match the preset optimal amplitude characterization value, controlling the output power of the ultrasonic transducer (4) according to the duty cycle adjustment value (S205). The ultrasound-based rapid pathological tissue processing method improves the effect of processing a pathological tissue.
