Radiofrequency ablation method and radiofrequency ablation system for nerve ablation

Abstract

The invention provides a radiofrequency ablation method and a radiofrequency ablation system for nerve ablation. The radiofrequency ablation system comprises a central processing and control module, and a radiofrequency releasing module, a volume impedance measuring module, a temperature monitoring module and an alarming and automatic storage module, which are respectively connected with the central processing and control module. The central processing and control module is used for generating an instruction parameter and also for controlling the radiofrequency releasing module according to the monitoring result of the volume impedance measuring module and the temperature monitoring module; the volume impedance measuring module is used for measuring volume impedance of a target tissue so as to provide evidence for positioning the target tissue and judging the damage degree of the radiofrequency; the temperature monitoring module is used for monitoring the temperature on the periphery of the target tissue in real time so as to prevent the excessive damage of a target tubular cavity; the alarming and automatic storage module is used for comprehensively analyzing a signal from the monitoring module and issuing an alarm in time for the situation exceeding a preset safety threshold value and for automatically sorting and storing the utilized parameters and collected information in the ablation process.

Description

technical field [0001] The invention relates to a radiofrequency ablation method, in particular to a radiofrequency ablation method with guiding parameters and monitoring means, and to a corresponding radiofrequency ablation system, belonging to the technical field of medical devices. Background technique [0002] In the occurrence, evolution and development of many diseases, the abnormality of autonomic nerves is a key factor that plays an important role. For example, the excessive enhancement of renal sympathetic nerve activity plays an important role in many diseases: such as refractory hypertension, chronic cardiac insufficiency, renal insufficiency, glucose metabolism disorders, polycystic ovary syndrome, etc. Another example is the influence of over-excitement of the vagus nerve on peptic ulcers, which has also attracted long-term attention and research in the medical field, and vagotomy can reduce the secretion of gastric acid. As another example, although the pathog...
