技术领域Technical Field
本发明涉及医疗器械技术领域，具体涉及一种瓣膜置换线及其使用方法。The present invention relates to the technical field of medical devices, and in particular to a valve replacement wire and a use method thereof.
背景技术Background technique
瓣膜是人或某些动物的器官里面可以开闭的膜状结构。每个人的心脏内都有四个瓣膜，即连结左心室和主动脉的主动脉瓣、连结右心室和肺动脉的肺动脉瓣、连结左心房和左心室的二尖瓣和连结右心房和右心室的三尖瓣，它们均起单向阀门作用，使血液只能从一个方向流向另一个方向而不能倒流。多种病因可导致瓣膜损坏，早期瓣膜病变没有明显的症状，直至左心衰竭时可出现呼吸困难(劳力性呼吸困难、阵发性夜间呼吸困难、急性肺水肿)、咳嗽、咯痰、咯血、倦怠、紫绀等表现，右心衰竭时可出现颈静脉怒张、肝脏肿大伴压痛、下肢可凹性浮肿等症状，晚期可发生腹水和心源性肝硬化。The valve is a membrane-like structure that can be opened and closed inside the organs of humans or certain animals. There are four valves in everyone's heart, namely the aortic valve connecting the left ventricle and the aorta, the pulmonary valve connecting the right ventricle and the pulmonary artery, the mitral valve connecting the left atrium and the left ventricle, and the tricuspid valve connecting the right atrium and the right ventricle. They all act as one-way valves, so that blood can only flow from one direction to another and cannot flow back. A variety of causes can lead to valve damage. Early valvular lesions have no obvious symptoms until left heart failure, which may cause dyspnea (exertional dyspnea, paroxysmal nocturnal dyspnea, acute pulmonary edema), cough, sputum, hemoptysis, fatigue, cyanosis and other manifestations. In right heart failure, symptoms such as distended neck veins, enlarged liver with tenderness, and concave edema of the lower limbs may occur. In the late stage, ascites and cardiogenic cirrhosis may occur.
瓣膜置换是目前解决绝大多数瓣膜疾病的手段，由于在进行瓣膜置换时，需要利用缝线将其固定在瓣环上。为了使瓣膜固定于瓣环无移位，换瓣线的结不能松脱，通常外科医生会花费一定时间打多个结，增加的手术时间会相应增加手术风险；此外，腔镜等微创手术在心脏外科的发展越来越快，腔镜手术视野暴露不佳，进一步增加了打结的困难和手术时间。Valve replacement is currently the solution to most valvular diseases. During valve replacement, sutures are needed to fix the valve to the valve ring. In order to fix the valve to the valve ring without displacement, the knot of the valve replacement line cannot be loosened. Surgeons usually spend a certain amount of time to tie multiple knots. The increased operation time will increase the surgical risk accordingly. In addition, minimally invasive surgeries such as laparoscopy are developing faster and faster in cardiac surgery. The poor exposure of the field of view in laparoscopic surgery further increases the difficulty of knotting and the operation time.
