背景技术Background technique
二尖瓣关闭不全是当今最常见的瓣膜病变之一,主要原因有二尖瓣环扩张、腱索功能不全、二尖瓣粘液变性、瓣叶脱垂、风湿性心瓣膜病、缺血性病变等。二尖瓣直视成形术及人工瓣膜置换术是治疗二尖瓣关闭不全的最有效方法,但是由于手术需要体外循环技术支持,给人体带来的创伤比较大,对高龄患者和有较多合并症患者,有相当高的并发症和死亡率。Mitral valve insufficiency is one of the most common valvular diseases today, the main reasons are mitral valve ring dilatation, chordal insufficiency, mitral valve mucus degeneration, valve leaflet prolapse, rheumatic heart valve disease, ischemic disease wait. Direct mitral valvuloplasty and artificial valve replacement are the most effective methods for the treatment of mitral valve insufficiency, but because the operation requires extracorporeal circulation technical support, the trauma to the human body is relatively large, and there are many complications for elderly patients. disease patients, there are quite high morbidity and mortality.
近年各国的医务人员和科研人员进行了经导管二尖瓣修复技术的探索,主要的介入治疗方式有瓣环成形术、负压抽吸缝合技术及二尖瓣钳夹术等,其中以二尖瓣钳夹术疗效最为可靠。二尖瓣钳夹术通过房间隔穿刺将一个可植入的瓣膜夹合器送至二尖瓣附近,将前后瓣叶的游离缘进行钳夹固定,使瓣叶在收缩末期对合良好,减少返流。传统瓣膜夹合系统通过丝线控制夹片的开合,丝线具备较好的柔顺性,利用丝线易于调节夹片的开合角度。然而,丝线使用过程中,存在较大的断裂风险,可靠性低,并且夹合完成后,不易从夹片上拆除。In recent years, medical personnel and researchers from various countries have explored transcatheter mitral valve repair techniques. The main interventional methods include annuloplasty, negative pressure suction suture technique, and mitral valve clamping. The curative effect of valve forceps is the most reliable. Mitral valve clipping sends an implantable valve clamp to the vicinity of the mitral valve through atrial septal puncture, and clamps and fixes the free edges of the anterior and posterior valve leaflets, so that the valve leaflets can fit well at the end of systole, reducing Reflux. The traditional valve clamping system controls the opening and closing of the clips through silk threads. The silk threads have good flexibility, and the opening and closing angle of the clips can be easily adjusted by using the silk threads. However, during the use of the silk thread, there is a greater risk of breaking, and the reliability is low, and it is not easy to remove from the clip after the clip is completed.
