Classification of medical ultrasonic products?

There should be many kinds. I sell CNC tools grinders, milling cutters, taps and drills. You asked about the classification of medical ultrasonic products. I have a friend who is also a doctor. I asked him if he wanted to buy a medical ultrasound. Medical ultrasonic cleaning machines have different configurations according to different requirements for cleaning specific objects, which can be divided into single-tank medical ultrasonic cleaning machines, double-tank medical ultrasonic cleaning machines (ultrasonic cleaning and ultrasonic flushing), three-tank medical ultrasonic cleaning machines (ultrasonic cleaning, ultrasonic flushing and boiling oil filling) and four-tank medical ultrasonic cleaning machines (ultrasonic cleaning, ultrasonic flushing, boiling oil filling and drying).
