Description

[TECHNICAL FIELD] The present invention relates to a skin treatment apparatus and a driving method thereof. In particular, the present invention relates to a technical concept capable of improving treatment efficiency in a method of treating skin by irradiating the skin with electrical energy. [BACKGROUND ART] A method of performing skin disease treatment and fat treatment using electrical energy such as RF pulse energy or high-frequency energy is known. As an example, there are a unipolar method in which the body is used as a (-) ground and a (+) handpiece is brought into contact with the skin and used in a vertical descending manner, and a bipolar method in which the skin is suctioned and electrical energy is applied from both sides. One example of such a bipolar method is also disclosed in a Korean registered patent filed and registered by the present applicant (Registration No. 10-2407711, "Therapeutic Handpiece Having Vacuum Cap", hereinafter referred to as the 'Prior Patent'). The contents described in the Prior Patent may be incorporated as a reference of the present invention. As disclosed in the Prior Patent, when the skin is suctioned to form the skin threedimensionally and electrical energy is irradiated through disposed electrodes, fatty components can be melted to obtain a therapeutic effect. However, such a conventional method has a problem in that the skin may not adhere well to the electrodes. FIG. 1 is a view for explaining a problem of a conventional skin treatment apparatus. As shown in FIG. 1, a conventional skin treatment apparatus 10 forms a negative pressure through a through-hole 12 to suction the skin into a cavity provided in the skin treatment apparatus 10, and then performs skin treatment by irradiating electrical energy through an electrode pair 11. However, as shown in FIG. 1, when the skin is suctioned, the suctioned skin is formed like a mountain peak, so the degree of close contact with the electrodes disposed at both ends becomes significantly low. In general, when suction is performed by simply applying negative pressure through a vacuum device, only about 30 to 40% of the suctioned skin area comes into contact with the electrodes, and the remaining 60 to 70% does not adhere. Since electrical energy is irradiated only to the adhered skin region, there is a problem that the effect of skin treatment is reduced. That is, even if the suction pressure of the skin is increased, there is a limit to the degree to which the skin adheres to the electrodes. * Prior Art Documents - Patent Documents (Patent Document 0001) Patent Document 1. Korean Registered Patent (Registration No. 10-2407711, "Therapeutic Handpiece Having Vacuum Cap") [DETAILED DESCRIPTION OF THE INVENTION] [TECHNICAL PROBLEM] An object to be solved by the present invention is to provide a technical concept capable of dramatically increasing an area of contact with electrodes in a state where the skin is suctioned into a cavity, thereby improving a therapeutic effect through electrical energy. Another object is to provide a technical concept capable of applying pressure to the skin to provide a massage effect, thereby causing the tissue of skin fat to be destroyed or softened so that it can be more readily decomposed by electrical energy. [SOLUTION TO PROBLEM] A skin treatment apparatus according to an embodiment of the present invention for solving the above technical problem includes: a skin accommodating cap having an open lower surface and a cavity therein; an electrode pair provided such that, when a target portion of skin is suctioned toward the cavity of the skin accommodating cap, the suctioned skin comes into contact within the cavity of the skin accommodating cap, the electrode pair being disposed to face each other in a first direction; a driving unit configured to drive a pressing plate so that the pressing plate can advance into and retreat from an inner direction of the cavity; a controller for controlling the driving unit; and at least one pressing plate which is driven by the driving unit so as to be able to advance into the cavity from a second direction different from the first direction and which increases an area of contact with the electrode pair by pressing inward the skin suctioned into the cavity. The skin treatment apparatus may include a pair of pressing plates disposed to face each other in the second direction. The controller may control the electrode pair to differentially perform whether to irradiate an RF pulse or an irradiation intensity according to driving of the pressing plate. At least one of the at least one pressing plate or the electrode pair may be formed to be inclined at a predetermined angle such that a lower portion of an inner surface facing the inside of the cavity protrudes inward more than an upper portion thereof. The driving unit may further drive the electrode pair so that the electrode pair can advance into and retreat from the inner direction of the cavity. The ski
