Treatment device using high frequency

A treatment device using high-frequency wave, comprising:

• a main body including a high-frequency wave generating unit;
• a contact-type hand piece detachably provided at a coupling unit of the main body, the contact-type hand piece having a first electrode unit that provides high-frequency energy generated from the high-frequency wave generating unit to a skin surface;
• an invasive hand piece detachably provided at the coupling unit of the main body, the invasive hand piece having a second electrode unit that provides high-frequency energy generated from the high-frequency wave generating unit to an inner portion under the skin;
• a controller controlling high-frequency energy provided from the high-frequency wave generating unit to the first electrode unit or the second electrode unit;
• and
• a sensing unit sensing a type of a hand piece connected with the coupling unit, of the contact-type hand piece and the invasive hand piece,
• wherein the invasive hand piece further includes a tilting unit that leads an end of the second electrode unit to penetrate into the skin surface with an inclination.
