本实用新型属于医疗器械技术领域，具体涉及一种支气管封堵器。The utility model belongs to the technical field of medical instruments, in particular to a bronchial occluder.
背景技术Background technique
目前，支气管胸膜瘘、难治性气胸等呼吸系统疾病正在严重危害着人们的健康，不仅增加患者的治疗费用、延长住院时间，一旦病情加重，可导致死亡。At present, respiratory diseases such as bronchopleural fistula and refractory pneumothorax are seriously endangering people's health, not only increasing the treatment cost of patients, prolonging the hospitalization time, but also leading to death once the condition worsens.
经支气管镜下腔内封堵治疗是近年来发展的一种用于治疗支气管胸膜瘘的新型的医疗手段，其原理是在支气管镜下，对支气管胸膜瘘引流支气管进行封堵，从而达到封闭瘘口的目的。Bronchoscopic endoluminal closure therapy is a new type of medical method developed in recent years for the treatment of bronchopleural fistula. mouth purpose.
经支气管镜下腔内封堵治疗是一种有效的支气管镜介入技术，可使患者免于接受电视辅助胸腔镜手术(VATS)或其他外科手术，减少医疗费用、缩短患者住院时间。Bronchoscopic endoluminal closure therapy is an effective bronchoscopic interventional technique, which can save patients from receiving video-assisted thoracoscopic surgery (VATS) or other surgical operations, reduce medical expenses, and shorten the hospital stay of patients.
用于封堵支气管的方法总体上可分为封堵剂和封堵器两类：1、封堵剂包括自体血+凝血酶、纤维蛋白原+凝血酶、纤维织物碎屑及纤维蛋白复合物、聚乙二醇等。封堵剂对血气指标的影响与常规支气管镜相近，缺点为部分患者在接受封堵剂治疗后，可能存在封堵剂自行脱落的可能，导致治疗失败；封堵器主要包括瓦塔纳贝(Watanabe)支气管塞(硅酮材料)、支气管镜肺减容活瓣、球囊、弹簧圈和盲端支架等，美国学者特拉瓦林(Travalin)等采用肺减容支架治疗难治性气胸，结果有47.5％的患者漏气完全停止，45.0％患者漏气减少。封堵剂治疗失败的患者可将封堵器作为一种治疗选择。封堵器封堵治疗方法因为应用面广，创口小，感染率小，术后并发症少，患者恢复快，死亡率低，费用相对低廉的优点而被越来越广泛地应用于临床实践。The methods used to occlude the bronchus can be generally divided into two categories: occluder and occluder: 1. The occluder includes autologous blood + thrombin, fibrinogen + thrombin, fiber fabric debris and fibrin complex , polyethylene glycol, etc. The effect of blocking agents on blood gas indicators is similar to that of conventional bronchoscopy. The disadvantage is that after receiving blocking agent treatment, the blocking agent may fall off by itself, resulting in treatment failure; the blocking agent mainly includes Vatanabe ( Watanabe) bronchial plug (silicone material), bronchoscopic lung volume reduction valve, balloon, coil and blind end stent, etc. American scholar Travalin (Travalin) used lung volume reduction stent to treat refractory pneumothorax, the results In 47.5% of the patients, the air leak was completely stopped, and in 45.0% of the patients, the air leak was reduced. An occluder can be used as a treatment option for patients who have failed occluder therapy. Occluder occlusion therapy is more and more widely used in clinical practice because of its advantages of wide application, small wound, low infection rate, few postoperative complications, quick recovery of patients, low mortality rate and relatively low cost.
