The subjects will first undergo interventional bronchoscopy to reach the target lesion through the bronchial pathway. Then the lung lesions will be treated with radiofrequency ablation using the pulmonary radiofrequency ablation system and the disposable pulmonary radiofrequency ablation catheter. During the study, eligible subjects will be followed up intraoperatively, 24 hours after operation, before discharge/ 7 days after operation (whichever occurs first), 30 days (±7 days) after operation, 3 months (±7 days) after operation, 6 months (±15 days) after operation, 9 months (±15 days) after operation, and 12 months (±15 days) after operation.
It is a multicenter, single group target value clinical trial to evaluate the safety and effectiveness of radiofrequency ablation for peripheral lung tumors under the conjunction of the pulmonary radiofrequency ablation system with the disposable pulmonary radiofrequency ablation catheter developed by Hangzhou Broncus Medical Co., Ltd.
