Abstract

冠状动脉支架,由不锈钢管经激光熔刻成网管状结构,网管结构由多个波形环状结构组成,环状结构依序上下排列,上下排由连接键连接于波谷之间,每一环状结构由若干单波形支撑件组成,其特点是:支撑件为8个,各支撑件顶部为弹簧压圈结构;每三排环状结构为一基本组,第一与第二排环状结构之间由4个连接键均布连接,第二与第三排之间由2个连接键均布连接,上下方连接键错位分布,两基本组之间由二个连接键均布连接,且上下方连接键之间的径向线呈90度夹角;所述支架以中心的径向剖面为中心面呈镜面对称。

Description

冠状动脉支架
本实用新型涉及一种医疗器械，具体属于一种介入性心脏病学用于治疗冠状动脉阻塞的冠状动脉支架。
血管内介入治疗技术是在医学影像设备的导引下，利用穿刺针、导丝和导管等器械所进行的诊断与治疗操作，已成为治疗各种威胁人类健康疾病的最先进的医疗手段之一。实施微创伤介入治疗技术有赖于微创伤医疗器械，其中PTCA(经皮穿刺冠状动脉成形术)心导管是微创伤介入医疗器械中最具代表性的高技术产品，冠状动脉支架不仅可用于在PTCA手术中发生急性冠状动脉阻塞时的应急之用的医疗器械，还可使复杂的冠状动脉病人得到治疗。
现有的冠状动脉支架形式有多种，它们各有特色，其目的都是要提高内支架的力度和细度。但现有的冠状动脉支架由于其结构上的局限，有些支架在扩张后的轴向缩短率大，金属表面覆盖率较大，有些支架柔软性欠佳，故仍有待进一步提高。
本实用新型的目的在于提供一种扩张后金属表面覆盖率低，轴向缩短及径向回复度小，轴向柔性好，支撑力高且分布均匀的冠状动脉支架。
本实用新型的目的是通过以下技术方案实现的：一种冠状动脉支架，由不锈钢管经激光熔刻成网管状结构，所述网管结构是由多个波形环状结构组成，这些环状结构依序上下排列，且上下排环状结构由连接键连接于波谷之间，所述每一环状结构由若干单波形支撑件组成，其特点是：所述支撑件为8个，各支撑件顶部为弹簧压圈结构；每三排环状结构为一基本组，第一与第二排环状结构之间由4个连接键均布连接，第二与第三排之间由2个连接键均布连接，且上下方连接键的径向线呈45度夹角α错位分布；两基本组之间由二个连接键均布连接，且上下方连接键之间的径向线呈90度夹角β错位分布；所述支架以其中心的径向剖面为中心面呈镜面对称。
本实用新型由于将不锈钢管激光熔刻为波形环状结构的网管状，将支撑件设计为8个，并将单波形支撑件的顶部设计为弹簧压圈结构，这样与同类支架相比，可有效提高其径向支撑力；并且，本实用新型上下方连接键之间呈45、90度夹角错位分布，可提高支架本身的弯曲和柔软性；同时，本实用新型整个支架结构以其中心的径向剖面为中心面呈镜面对称，这样可使支架在柔软性和径向强度方面沿轴向均匀对称分布。
以下结合附图及附图给出的实施例对本实用新型作进一步说明：
图1为本实用新型的网管状结构的展开视图；
图2为图1中支撑件的放大示意图；
图3为本实用新型立体结构中支撑件位置的分布示意图(俯视)。
如图1、2、3所示，一种冠状动脉支架，由不锈钢管经激光熔刻成网管状结构10，所述网管结构10是由多个波形环状结构1、2、3……组成，这些环状结构依序上下排列，且上下排环状结构由连接键50连接于波谷6之间，每一环状结构1是由若干个单波形的支撑件4组成，本实用新型中支撑件4为八个，各支撑件4顶部形成一弹簧压圈结构41(见图2)。每三排环状结构1、2、3为一基本组20，第一与第二排环状结构1、2之间由四个连接键51均布连接，第二与第三排2、3之间由二个连接键52均布连接，且上下方连接键51、52的径向线呈45度夹角α错位分布；两基本组20之间由二个连接键53均布连接，且上下方连接键52、53之间的径向线呈90度夹角β错位分布(见图3)。整个支架以其中心的径向剖面30为中心面呈镜面对称。本实用新型由于上述结构而可使金属表面覆盖率低，轴向缩短及径向回复度小，轴向柔性好，支撑力高且分布均匀。
