The present disclosure relates to a high-intensity focused ultrasound device, and more specifically, to a high-intensity focused ultrasound device provided in a cartridge with a structure that prevents contact between the drive unit and the ultrasonic transmission medium.

In general, when the shape of a ceramic that generates ultrasonic waves is made circular, the ultrasonic waves are focused at the center of the sphere, and at this time, it has a certain form of energy distribution, which is referred to as high intensity focused ultrasonic.

When ultrasonic waves are focused, heat is generated at the focus by the focused high-intensity ultrasonic energy, and the vibration of the ultrasonic waves causes vibrations between molecules in the tissue, and friction between molecules becomes a source of heat generation, and heat is generated at the focus of the ultrasonic waves. Coagulation of tissue occurs.

A typical high-intensity focused ultrasound device can move the vibrator using a driving device and sensor to form multiple treatment points using a single vibrator. Here, the vibrator and drive sensor may be provided within the cartridge. An ultrasonic transmission medium (eg, water, oil, gel, etc.) exists within the cartridge, and the vibrator can generate the output of high-intensity focused ultrasonic waves while moving through the ultrasonic transmission medium. In this case, the driving part that moves the vibrator is electrically and mechanically vulnerable to moisture and needs to be separated from the medium.
