KR-102963931-B1 - BIPOLAR TYPE RF ENERGY GENERATOR

Abstract

The present invention relates to a bipolar RF energy generating device. One embodiment of the bipolar RF energy generating device comprises a cartridge housing portion having one surface in contact with the skin, at least three RF electrode portions positioned spaced apart from one surface of the cartridge housing portion and in contact with the skin, and applying electric power to two of the RF electrode portions. By adjusting the spacing between the RF electrode portions to which electric power is applied and the frequency of the RF energy, the depth of the skin to which the RF energy is delivered can be varied, and uniform energy is delivered for each skin depth, thereby improving the treatment effect in the bipolar method and diversifying the types of treatments.

Description

Bipolar Type RF Energy Generator The present invention relates to a bipolar RF energy generator, and more specifically, to a bipolar RF energy generator that controls the spacing between RF electrodes and delivers uniform energy according to skin depth using multiple frequencies. Generally, RF energy generators used for cosmetic purposes are devices that perform treatments by heating the skin and underlying tissues using RF electrodes (radio frequency). RF energy generators are used to restore the skin by raising its temperature after cryolipolysis procedures by delivering RF energy to the skin after contacting RF electrodes, and also for skin treatments that heat the skin and underlying tissues to induce collagen contraction or trigger a wound healing response. Recently, due to the increasing interest in skin aesthetics, bipolar RF energy generators are being utilized in various ways, such as skin remodeling/resurfacing through collagen contraction or wound healing responses in the lower dermis, wrinkle removal, and the treatment of sebaceous glands, hair follicle adipose tissue, and spider veins. RF energy generators mainly use monopolar types with one electrode in contact with the skin and bipolar types with two electrodes in contact with the skin. A bipolar RF energy generator utilizes a pair of RF electrodes in contact with the skin, where one electrode acts as the (+) electrode and the other as the (-) electrode; RF energy emitted from the (+) electrode—that is, high-frequency energy—flows into the (-) electrode, delivering RF energy into the skin. Conventional bipolar RF energy generators have a structure in which the spacing between a pair of RF electrodes in contact with the skin is fixed, and since the depth of RF energy delivery into the skin can only be controlled by adjusting the RF energy frequency, there was a problem in that the depth of RF energy delivery into the skin was limited. In addition, conventional bipolar RF energy generators control the transmission depth of RF energy solely by adjusting the frequency, which has the problem of being unable to deeply penetrate high-frequency RF energy into the skin. In other words, conventional bipolar RF energy generators have limitations in the depth of RF energy delivery within the skin, and since high-frequency RF energy cannot penetrate deeply into the skin, the effectiveness of the procedure is limited, and there were problems with difficulty in applying them to various procedures.
