????LIPO-X Cavitation funtion
????Cavitation handle uses ultrasound to break fat and make it easy to removed. Liquid may seem to fill up the space,
but it actually contains gases. If the pressure on liquid is unstable, the gas gathers on the weak side and creates air droplets,
and this phenomenon is called Cavitation.
????And when the pressure applied again on the bubble, it breaks and erodes the surrounding area with strong pressure.
Lipo-X uses this phenomenon for body contouring.
