Lung radiofrequency ablation system, lung radiofrequency ablation control method, lung radiofrequency ablation control device, computer readable medium and radiofrequency ablation catheter

Abstract

The invention relates to a lung radiofrequency ablation system, a lung radiofrequency ablation control method, a lung radiofrequency ablation control device, a computer readable medium and a radiofrequency ablation catheter. The lung radiofrequency ablation system comprises the radiofrequency ablation catheter, a heat exchange medium conveying device and a control module; the heat exchange mediumconveying device is used for providing heat exchange media for the peripheral position of an electrode of the radiofrequency ablation catheter; the control module is used for correspondingly driving the heat exchange medium conveying device according to impedance information of a loop in which the electrode is located in the radiofrequency ablation catheter. The lung radiofrequency ablation systemmonitors the ablation schedule by collecting the impedance information; further, the used radiofrequency ablation catheter is correspondingly improved.

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...

AI Technical Summary

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.
