Description

technical field [0001] The present application relates to the field of interventional therapy, in particular to a control method, system and computer medium of a pulmonary nerve ablation system. Background technique [0002] Chronic Obstructive Pulmonary Disease (COPD) is the most common disease of the respiratory system. In our country, according to the existing epidemiological survey evidence, the prevalence of COPD among adults over 40 years old is 10%. %about. [0003] At present, COPD mainly relies on drug treatment, and anticholinergic drugs are used to specifically block M receptors, causing airway smooth muscle relaxation, airway relaxation and mucus secretion reduction, thereby reducing airway obstruction and relieving symptoms of COPD patients. Therapeutic ablation (Targeted Lung Denervatiom, TLD) lung denervation therapy ablation targets the parasympathetic nerve, blocking its innervation, so as to achieve permanent anticholinergic effect. This method has comple...

Problems solved by technology

[0007] The inventors found that in the related art, most of the loop catheters are electrophysiological mapping catheters, and most of the ablation catheters are unipolar ablation, so multiple ablations are required during the treatment process, so that the ablation forms a closed loop, and the operation process is cumbersome and complicated. Treatment effect is difficult to control

If the degree of ablation is insufficient, the ablation point is not easy to form a closed loop, and it is difficult to effectively block; if the degree of ablation is too high, the damage is too great, which is not good for the patient's recovery process

[0008] At the same time, the internal lumen diameter of the breathing circuit will gradually become smaller with the deepening of the intervention, while the shape of the ablation electrode in the related technology is relatively fixed, which is not well adaptable to the target tissues of different arrangements, and the ablation position is prone to be too high, resulting in excessive ablation. More nerve inactivation, greater impact on patients
