Problems solved by technology

[0011] However, in the actual use process, multiple electrodes are connected in series, and the ablation process cannot be monitored. The electrodes are rectangular electrodes, and the electrodes are not electrically isolated, so the ablation difference between the electrodes cannot be confirmed.

Abstract

The invention discloses a sympathetic nerve ablation catheter which comprises a guide insertion end used for being inserted into a fiberoptic bronchus along with a fiberoptic bronchoscope; the head end of the ablation device is connected to the guide insertion end, and the ablation device is provided with a detection electrode and an ablation electrode which are used for ablating sympathetic nerves; the control handle is connected to the tail end of the ablation device; and the connecting cable penetrates through the control handle and is connected to the detection electrode and the ablation electrode. According to the sympathetic nerve ablation catheter, the ablation effect can be monitored through the detection electrode in the ablation process, the operation effect is confirmed by stimulating tissue through the detection electrode after ablation is finished, the catheter does not need to be adjusted in the process, and the effectiveness of the detection position and the detection result is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices for ablation, in particular to a sympathetic nerve ablation catheter. Background technique [0002] Chronic obstructive pulmonary disease (COPD), a common preventable and treatable disease characterized by persistent airflow limitation, is currently considered incurable but treatable - slowing further loss of lung function, correcting Reversible changes, treatment of disease problems and symptoms. [0003] The parasympathetic nerve is one of the main nerves innervating the lungs. By releasing acetylcholine, it interacts with cholinergic receptors throughout the bronchial tree, thereby causing airway smooth muscle contraction, promoting airway mucus secretion and regulating local validation responses. Pulmonary parasympathetic nerve inflammation The reflex arc theory means that the vagus nerve can innervate the distal airway, even the alveoli, and innervate the airway sensor. The vagus ner...
