Background
Chronic obstructive pulmonary diseases such as emphysema are common lung diseases. Traditionally, the internal treatment of emphysema includes oxygen inhalation, prevention of pulmonary infection, bronchial spasmolysis, etc., but the curative effect is very limited; the surgical treatment mainly comprises lung volume reduction surgery, but has more limitations, such as strict surgical indications, more complications, anesthesia and complications related to anesthesia, difficult prediction of preoperative curative effect, incapability of making up for the result of unsatisfactory curative effect caused by excessive or insufficient excision after surgery, high surgical cost, greater mental and physical pain, and higher postoperative mortality rate due to the fact that part of patients cannot tolerate surgery due to poor lung functions, and the application of the surgical operation is limited.
The bronchoscope is used for carrying out the bronchial valve interventional therapy on the emphysema, so that pulmonary diseases such as the emphysema can be better treated, the life quality of a patient is improved, and the wound of the patient in the operation process is reduced. At present, the bronchus that mainly uses in the international market is umbelliform bronchus lamella, and its theory of operation all is that one-way flap can prevent outside air to get into the emphysema district, can let the residual gas in emphysema district or secretion pass through one-way flap discharge emphysema district simultaneously again, through the ventilation of one-way flap restriction emphysema district pulmonary tissue, makes emphysema district pulmonary tissue collapse to reach the effect of alleviating lung disease.
For example, chinese patent application No. CN201310750987.4 discloses an umbrella-shaped bronchial valve, which comprises three parts, namely, an elastic frame, an isolation membrane and a connecting rod. The frame comprises six supporting rods and five anchor rods, the connecting rod is connected with a recovery handle, and a layer of polyurethane film is attached to the outer side surface of each supporting rod to form an umbrella-shaped isolation film. After bronchus was put into to this umbelliform bronchus flap, isolation film and bronchus inner wall closely laminated to prevent external gas to get into emphysema district tissue, the umbelliform structure of design can make the secretion in the emphysema district lung discharge to the near-end along the narrow and small clearance between isolation film and the bronchus inner wall again from the distal end, through the ventilation of restriction emphysema district lung tissue, makes emphysema district lung tissue sink.
