Abstract

The invention relates to a catheter ablation device and a radiofrequency ablation catheter of the catheter ablation device. A continuous ablation kitchen can be formed by the catheter ablation device and the radiofrequency ablation catheter. The radiofrequency ablation catheter comprises a body, an extending section, an annular section and an annular electrode, the body, the extending section and the annular section are sequentially connected, the annular electrode is arranged on the annular section and provided with an ablation part, and the ablation part is continuously formed on the annular section. The radiofrequency ablation catheter is provided with the continuous annular electrode, the number of ablation times can be remarkably decreased, and the continuous ablation kitchen can be formed.

Description

technical field [0001] The invention relates to medical equipment, in particular to a catheter ablation device and a radiofrequency ablation catheter thereof. Background technique [0002] Radiofrequency ablation catheter is a kind of electrophysiological catheter, which has been widely used in the treatment of arrhythmia in recent years. Generally speaking, the catheter includes two functions of mapping electrical signals and radiofrequency ablation. After the catheter enters the heart, the electrical signal is first mapped to determine the abnormal pathway or abnormal electrical excitation point, and then these abnormal electrical signal pathways are ablated and isolated, so as to achieve the purpose of treatment. [0003] Atrial fibrillation is a common arrhythmia in which the myocardium loses its normal and regular diastolic movement and replaces it with rapid and uncoordinated weak peristalsis, thereby causing the atrium to lose its normal contraction. In 1997, Profes...
