Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a stent closure umbrella for pleural fistula. Background technique [0002] As we all know, bronchopleural fistula refers to the communication between the pleural cavity and the bronchi. It is a common complication after thoracic surgery, with an incidence of 1.5% to 28% after pneumonectomy and 4.5% to 20% after pneumonectomy. Bronchopleural fistula is often combined with empyema, and the course of the disease is protracted and unhealed. It is one of the main causes of death after lung resection. For benign lesions, such as tuberculosis, bronchiectasis, and chronic obstructive pulmonary disease, bronchopleural fistulas sometimes occur. At present, there is no effective method for the treatment of bronchopleural fistula and chronic refractory empyema clinically, and empyema is relatively common in the field of general thoracic surgery. The treatment is difficult, the cure rat...
