摘要： Disclosed are a radio-frequency ablation catheter having a spiral structure and equipment thereof. The radio-frequency ablation catheter has a long strip-shaped catheter body. A spiral electrode support is arranged at the front end of the catheter body. Multiple electrodes (2) are arranged on the electrode support. A control handle (8, 20) is arranged at the rear end of the catheter body. Wall-attachment adjusting wires (6) having various structures can be arranged in the radio-frequency ablation catheter, so that the radio-frequency ablation catheter having a spiral structure can be adapted to target lumens of different diameters, and so that the electrodes (2) on the electrode support have a good wall-attachment state.
