Abstract

本发明提供的一种网式主动脉瓣成形环,其特征在于:包括设置环体、软质材料和网线,网线在环体互对应面上的软质材料串接,构成网式主动脉瓣成形环。所述的网线采用2-Oproline或者3-Oproline手术滑线。手术时,沿主动脉瓣窦下的主动脉瓣环,用间断或连续缝线,从瓣窦根部的主动脉向瓣下出针,作褥式缝针进主动脉瓣窦,连续缝线可固定之。间断缝线亦照此缝法,可固定网式主动脉瓣成形环于瓣下,心脏舒张期垫托起主动脉瓣叶,致心脏舒张时主动脉瓣向左心室关闭,以此达到纠治主动脉瓣关闭不全。网式主动脉瓣成形环操作简单,能明显缩短手术时间,安全可靠性,具有良好的组织相溶性和耐久性,是一种理想的主动脉瓣成形环。

Description

网式主动脉瓣成形环
技术领域:
本发明涉及医疗器械领域,特别是指一种用于心脏外科手术用的器械,更具体地说是提供一种用于主动脉瓣脱垂、瓣叶穿孔,引发的主动脉瓣关闭不全的心脏主动脉瓣成形手术的网式主动脉瓣成形环。
背景技术:
心脏的主动脉瓣位于心脏左侧,在左心室与主动脉之间。主动脉瓣与二、三尖瓣不同的是舒张期向左心室关闭,心收缩期间,健康的主动脉瓣打开,主动脉瓣下无腱索,三个瓣窦在心脏舒张期被血流充盈膨胀而关闭主动脉瓣口,以防止血液从主动脉回流进入左心室。常人的血压120/80mmHg,其80mmHg的舒张压,可以让血液大量通过关闭不全的主动脉瓣回流到左心室腔,其回流的量和速度,对左心房、室的血流量有极大的影响,以致左心房室淤血,引发急性左心衰、肺淤血。如瓣窦扩张,瓣叶脱垂、瓣叶穿孔时,心脏舒张期主动脉瓣不能向左心室关闭,致舒张压显著下降,心脏血供的冠状动脉血流过于低下,引发心肌供血不全,致心功能不全、心力衰竭、心律失常或心脏骤停,是影响到数百万患者的严重问题。
本申请人设计网式主动脉瓣成形环,用间断或连续缝线,把成形环固定在主动脉瓣下的瓣环上,在心脏舒张期环中的“网”垫托住主动脉瓣不向左心室过伸或脱垂,使主动脉瓣关闭,达到纠治主动脉瓣关闭不全的目的。
世界上至今尚无主动脉瓣成形环的设计。
发明内容:
本发明的目的:为简化心脏主动脉瓣成形术操作,在心脏舒张期,其环中的“网”垫托住向左心室过伸脱垂的主动脉瓣,使主动脉瓣向左心室关闭,以达纠治主动脉瓣关闭不全的目的,提供一种网式主动脉瓣成形环。
本发明是这样实现的:
一种网式主动脉瓣成形环,其特征在于:包括设置环体、软质材料和网线,网线在环体互对应面上的软质材料串接,构成网式主动脉瓣成形环。
以上所述的网线采用2-Oproline或者3-Oproline手术滑线。
网式主动脉瓣成形环的安置操作方法:
手术时,沿主动脉瓣窦下的主动脉瓣环,用间断或连续缝线,从主动瓣窦根部的主动脉壁向下出针,作褥式缝针进主动脉瓣窦,重复连续缝线可固定之;间断缝线亦照此缝法,可固定网式主动脉瓣成形环于瓣下。心脏舒张期环中“网”垫托起主动脉瓣叶,致心脏舒张时主动脉瓣向左心室关闭,以此达到纠治主动脉瓣关闭不全目的。
本发明的优点和积极效果:
1、本网式主动脉瓣成形环结构简单、缝置操作技术简明易掌握。
2、主动脉瓣成形术是一项效果难以确定的复杂手术,应用网式主动脉瓣成形环,能显著缩短手术的时间,效果确切。
3、所用材质均为广泛用于心脏手术的物品,使用悠久,具有良好的组织相溶性和良好的耐久性。
4、网式成形环中的“网”,在心脏舒张期环中的“网”垫托住主动脉瓣向左心室过伸脱垂,以使主动脉瓣关闭,达到纠治主动脉瓣关闭不全的目的。
5、网式成形环应用中,对病变的瓣膜,尤其对脱垂,部分不须做手术整形,自身的瓣膜使用时间更长。
附图说明:
图1:为本网式主动脉瓣成形环的结构示意图;
图中标识说明:1-环体,2-软质材料,3-网线。
具体实施方式:
下面结合附图与具体实施方式对本网式主动脉瓣成形环作进一步详细描述:
实施例1
如图1所示,本网式主动脉瓣成形环,设置环体1、软质材料2和网线3,网线3采用2-0或3-Oproline手术滑线,在环体1互对应面上的软质材料2串接,构成网式主动脉瓣成形环。
手术时,沿主动脉瓣窦下的主动脉瓣环,用间断缝线,从瓣窦根部的主动脉壁向瓣下出针,作褥式缝针进主动脉瓣窦,间断缝线可固定之,固定网式主动脉瓣成形环于瓣下,心脏舒张期垫托起主动脉瓣叶,致心脏舒张时主动脉瓣向左心室关闭,以此达到纠治主动脉瓣关闭不全。
