HIGH INTENSITY FOCUSED ULTRASOUND TREATMENT HEAD WITH ADJUSTABLE FOCAL LENGTH

摘要

The present invention relates to a treatment head of high-intensity focused ultrasonic waves with an adjustable focal length, comprising a transducer of high-intensity focused ultrasonic waves, a membrane, and a refractive lens unit. The transducer of high-intensity focused ultrasonic waves is equipped with an ultrasonic wave generation unit for generating ultrasonic waves with high intensity, and an ultrasonic wave irradiation surface for focusing the high-intensity ultrasonic waves generated from the ultrasonic wave generation unit. The membrane is formed to cover the ultrasonic wave irradiation surface, and forms a storage space for storing an ultrasonic delivery medium between the ultrasonic wave irradiation surface and the same. The refractive lens unit is installed to be separable on the ultrasonic wave irradiation surface as arranged inside the storage space, and adjusts a focal length of high-intensity ultrasonic waves by refracting the high-intensity ultrasonic waves radiated from the ultrasonic wave irradiation surface.
