Abstract
The present invention relates to an RF treatment device, a medical RF device, and control methods therefor. Specifically, provided are an RF treatment device, a medical RF device, and control methods therefor, the RF treatment device comprising: an RF generation unit for generating RF energy; a plurality of RF electrodes connected to the RF generation unit through an RF circuit and selectively inserted into body tissue to transmit RF energy to the body tissue; and a sensing unit for sensing a loss of the RF energy transmitted to the body tissue due to the impedance characteristics of the body tissue.
