  • Patent number: 9072525
    Abstract: Provided is a combinable electrode needle base structure in which a base to which electrode needles are coupled can be used in a combined or separated state to use the electrode needles according to the size and location of a lesion. In the combinable electrode needle structure, electrode needles are connected to the front side of an electrode needle base, and receive RF waves from RF (radio frequency) generator. The electrode needle base is divided into dividable bases to which the electrode needles are respectively coupled. When a lesion to be cauterized is large or cauterization should be concentrated, the dividable bases are combined and then used, and when a lesion is small or lesions are scattered, the dividable bases may be separated and then used.
