Problems solved by technology

[0004] The inventor found that when the existing radiofrequency ablation catheter for the lungs is working, the temperature of the electrode site rises too fast, and the tissue near the electrode becomes dry and charred and forms a "scab", which leads to the stop of the ablation and incomplete ablation
Moreover, the "scab" tissue is adhered to the electrode, and the surrounding organs will be damaged when the device is pulled out.

Abstract

The present application relates to a lung radiofrequency ablation system, a control method, a control device and a computer readable medium, and a radiofrequency ablation catheter, wherein the lung radiofrequency ablation system includes a radiofrequency ablation catheter; The heat exchange medium delivery device for the heat exchange medium; the control module of the heat exchange medium delivery device is correspondingly driven according to the impedance information of the loop where the electrode in the radio frequency ablation catheter is located. The lung radiofrequency ablation system of the present application monitors the ablation progress by collecting impedance information, and further makes corresponding improvements to the radiofrequency ablation catheter used.

Description

technical field [0001] The present application relates to the field of tumor minimally invasive ablation therapy, in particular to a pulmonary radiofrequency ablation system, a control method, a control device and a computer readable medium. Background technique [0002] Lung cancer is one of the most common malignant tumors. In clinical treatment, surgical resection is still the first choice for the treatment of early lung cancer. However, for lung cancer patients who are older, weaker, have poor cardiopulmonary function, or have complications, they are not suitable or tolerate conventional surgical resection. Therefore, many local treatment methods such as minimally invasive tumor ablation have emerged. Minimally invasive ablation of lung tumors includes radio frequency ablation (RFA), cryoablation, microwave ablation, etc. Among them, only radio frequency ablation is included in the clinical guidelines of the National Comprehensive Cancer Network for non-small cell lung...
