RADIO FREQUENCY ABLATION ELECTRODE FOR SELECTED TISSUE REMOVAL

摘要

A radio frequency ablation electrode for selected tissue removal is provided to easily cut through obstructed hard fiber to easily perform an operation for a patient long troubled with disc herniation. A radio frequency ablation electrode(100) for selected tissue removal includes a first electrode(110), a second electrode(120), a first electrode tip(112), and a second electrode tip(122). The first and second electrodes are inserted into a tissue. The first electrode tip is formed on an end of the first electrode and the second electrode tip is formed on an end of the second electrode. The first and second electrode tips are spaced apart from each other at a predetermined interval. A coil spring is connected to end portions of the first and second electrode. The coil spring has an end portion in a bent shape in a free state. The coil spring is transformed by pulling at least one of the first and second electrodes.
