In plain words

What the trial is, and whether it could suit you

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.
