发明名称 椎間板ヘルニア患者の椎間板から髄核の局所的アブレーションをするためのRF電極
摘要 The present invention relates to a radiofrequency electrode for selective ablation of a body tissue, comprising a first electrode 110 and a second electrode 120 to be inserted, through a catheter 60 , into the body tissue, wherein the first electrode tip 112 formed at the end of the first electrode 110 and the second electrode tip 122 formed at the end of the second electrode 120 are bonded at a predetermined interval. Specifically, a coil spring is bonded to the ends of the first electrode 110 and the second electrode 120 , and the coil spring is configured to have its end part bent in the free state and be transformed by pulling either or both of the first electrode and the second electrode. By using the electrode, ablation of a desired tissue region in a body with radiofrequency by easily controlling the direction and the position of the electrode tip can be easily performed.
