Description

Hand Piece for Medical

The present invention relates to a medical handpiece, and more particularly, to a medical handpiece capable of universal use by selectively or in combination with a heating function, a cooling function, and an ultrasonic function as needed.

In general, a skin beauty device is a device that manages the skin by applying sound pressure, ultrasound, high-frequency heating, etc. to the skin, and a conventional skin beauty device has only one of an ultrasonic function, a cooling function, and a heat function. Most of them.

Therefore, in the case of skin care treatment by applying two functions, for example, an ultrasonic function and a hot and cold function together, first, a skin beauty device with an ultrasonic function is used to primarily decompose cellulite to promote metabolism. After the treatment, a separate skin beauty device with hot and cold functions is used to perform skin care treatment that enhances skin elasticity and promotes blood circulation.

As described above, in the conventional procedure, the two functions are separate, and a lot of time and effort is required for the procedure, and since a cosmetic device having each function must be purchased separately, there is an undesirable problem in terms of economy.
