A multipolar simultaneous pulmonary artery radiofrequency ablation catheter, wherein the adjustment device is disposed on the control handle, the catheter body is hollow, the cavity is disposed within the catheter body, a lead wire, a temperature sensing wire, and a pull wire Is disposed in the cavity, one end of the catheter body is flexible, the flexible end is connected to the annular ring, the other end of the catheter body is connected to the control handle, and the pull wire One end of the pull wire is connected to the flexible end, the other end of the pull wire is connected to the adjustment device on the control handle, and the tension of the pull wire is adjusted to achieve radians control of the flexible end The shape memory wire is placed in the annular ring and one end of the shape memory wire extends to the tip of the annular ring. The other end of the shape memory wire passes through the root of the annular ring and is fixed to the flexible end of the catheter body. The annular ring is an electrode group in which each electrode is connected to a lead wire and a temperature detection wire. A multipolar simultaneous pulmonary artery radiofrequency ablation catheter comprising a lead wire and a temperature sensing wire electrically connected to the control handle through the catheter body. The device uses cold saline perfusion methods to protect the intima and has the advantages of simple operation, short operation time, and controllable and precise ablation. The device can be used to treat pulmonary hypertension by pulmonary denervation.
