Abstract

There is provided an electrode needle of an RFA device, which is inserted into a lesion portion to cauterize the lesion portion by using RF radiated from the RFA device, wherein an electrode pin having a tip end is coupled to one end of an electrode main body that can be held or grasped by a user's hand, one or more markers coated or plated with a radiation non-transmissive material thereon are inserted into or wound around an outer circumferential surface of the electrode pin, regions, excluding an end portion, of the electrode pin are wrapped, along with the markers, with an insulating tube, and heat is then applied thereto to allow the insulating tube to be contracted to fixedly compress the markers, whereby the position of the electrode pin can be easily recognized in a state in which the electrode needle is inserted for a medical operation.
