Abstract: Provided are a radio frequency ablation catheter, a control method and a control apparatus therefor, a radio frequency ablation system for lungs, a control method and a control apparatus therefor, and a computer-readable storage medium. The radio frequency ablation catheter includes an electrode. A heat exchange medium flow channel is provided inside the electrode. A dispersing device is provided on the electrode. A dispersing hole communicating with the heat exchange medium flow channel is provided at the dispersing device. A heat exchange medium output from the heat exchange medium flow channel is distributed by and flows out of the dispersing device. The electrode allows physiological saline to be perfused into a tissue ablated, thereby improving the electrical and thermal conductivity of the tissue ablated, maintaining balance of the impedance, maintaining the impedance in a relatively stable state, and enabling continuous output of radio frequency energy.
