Clinical Trial Summary

The goal of this pliot study al is to preliminarily evaluate the effectiveness and safety of transbronchial lung volume reduction surgery using the self-devloped endobronchial valves for chronic obstructive pulmonary disease patients with emphysema phenotype . The main questions it aims to answer are: Does self-devloped endobronchial valves improve the lung function、exercise capacity and symptons of participants? What surgery-related adverse events do participants have after transbronchial lung volume reduction surgery using the self-devloped endobronchial valves? Participants will: undergo transbronchial lung volume reduction surgery using the self-devloped endobronchial valves. receive follow-up before surgery (baseline) and 3 days, 4 weeks, 12weeks after surgery.
