修复心脏流出道用带瓣补片和带瓣管道 技术领域
本发明涉及改建或重构异常心脏流出道的修补器械， 特别涉及用于加宽心脏流 出道的带瓣补片和用于置换整个主、 肺动脉瓣的带瓣管道。 背景技术
用人造器官替代发生病变的心脏组织是治疗先天性心脏病的常用治疗方法。 以先天性紫绀型心脏病为例， 其病变之一是其右室流道狭窄， 心外科医生通常 需要采用自体心包片或用牛心包补片作为修补材料以加宽或重建流出道， 然而， 多 数患者因伴有肺动脉瓣关闭不全或无肺动脉瓣而导致右心负荷加重， 极大地影响了 患者术后治疗效果， 为此， 某些心外科医生不得不在手术过程中自行于补片材料上 缝上一个瓣叶， 此举虽能改善术后效果但因牢固性有限， 或材料发生钙化等导致长 期结果不能令人满意。 此外， 也有部分有条件的医生采用同种异体主动脉瓣或同种 异体肺动脉瓣， 作为右室流出道修补或替代。 虽然可以收到较好临床效果， 但因同 种材料的来源有限， 其储存、 运输都存在诸多问题。
先天性紫绀型心脏病病变之二是肺动脉发育不良， 需要重建带有肺动脉瓣的肺 动脉管道， 通常这类手术中可使用： ①同种异体主动脉带瓣管道， 但因同种材料的 来源有限， 其储存、 运输都存在诸多问题； ②猪主动脉瓣和一段人工血管； 或③人 工机械瓣和一段人工血管。猪主动脉瓣其瓣叶组织易发生疲劳和钙化其耐久性一直 令人担忧， 而机械瓣需要终身抗凝以及不可避免的抗凝相关并发症至今未能得到很 好的解决。 发明目的
本项发明的目的是解决现有技术中的不足， 提供一种用于加宽心脏流出道的带 瓣补片， 这种带瓣补片在加宽流出道的同时较好地解决肺动脉瓣关闭不全所引起的 返流， 更重要的是补片的瓣叶不仅可以明显改善术后患者血流动力学， 同时， 特有 的结构所赋予人工瓣叶具有极好的耐疲劳性， 显著提高术后患者远期生活质量。 依 据与这种带瓣补片类 的缝制结构， 本发明还提供了一种性能良好的带瓣管道。 发明内容
为达到发明目的， 本发明所釆取的技术方案是：
一种修复心脏流出道用带瓣补片， 所述带瓣补片包括内衬片、 外衬支撑片和 瓣叶， 所述内衬片上具有一个近似半圆弧形狭缝， 所述瓣叶下缘沿狭缝穿设于内衬 片与外衬支撑片之间， 且瓣叶上沿与内衬片之间构成一个自然的瓣兜， 缝线沿内衬 片狭缝边缘将内衬片、 瓣叶下缘和外衬支撑片三者缝合在一起， 瓣叶下缘被固定在 内衬片、 外衬支撑片之间。
其中， 所述修复心脏用带瓣补片自瓣叶上缘以上部分为只具有内衬片的单层结 构； 所述内衬片沿瓣叶上缘上延 3.5〜8.5cm， 外衬支撑片与内衬片于瓣叶上缘处缝 合在一起， 所述内衬片和外衬支撑片沿瓣叶下缘向下延长 1.5〜6.5cm; 所述内衬片、 瓣叶和外衬支撑片为同种组织片或经化学改性处理的异种组织片； 所述经化学改性 处理的异种组织片为经抗钙化改性处理的牛心包片； 所述瓣叶下缘置于内衬片和外 衬支撑片之间的部分切有数个切口， 以使瓣叶下缘缝合更加平整。
一种修复心脏流出道用带瓣管道， 所述带瓣管道由内衬管、 三片瓣叶和外衬支 撑管构成， 内衬管壁周向一圈设有三个近似半圆弧形狭缝， 所述三片瓣叶下缘分别 沿三个狭缝穿设于内衬管与外衬支撑管之间， 缝线沿内衬管狭缝边缘将内衬管、 三 片瓣叶周边部分和外衬支撑管缝合固定在一起， 使三片瓣叶的上沿对称、 平整地对 合于内衬管内， 所述带瓣管道的内衬管、 外衬支撑管两端延伸为无支架瓣上、 下管 道。 其中， 所述内衬管、 瓣叶和外衬支撑管为同种组织片或经化学改性处理的异种 组织片； 所述经化学改性处理的异种组织片为经抗钙化改性处理的牛心包片； 所述 瓣叶周边置于内、 外衬管之间的部分切有数个切口， 以使固定缝合更加平整； 所述 上管道为内衬管沿瓣叶向上延伸的部分， 无支架瓣下管道为内衬管和外衬支撑管沿 瓣叶下弧延伸的部分； 所述外衬支撑管外还套设由医用高分子材料或金属材料制成 的刚性支撑结构。
本发明所能产生的有益效果是：
1、 本发明修复心脏流出道用带瓣补片和带瓣管道的瓣叶与内衬片 /管和外衬支 撑片 /管缝合在一起， 且瓣叶下缘位于内衬片 /管和外衬支撑片 /管之间， 免除了仅靠 缝线固定瓣叶， 使瓣叶的牢固性更好， 可以显著提高患者术后远期治疗效果。
2、 瓣叶与内衬片 /管和外衬支撑片 /管缝合时， 夹于内衬片 /管和外衬支撑片 /管 的瓣叶下缘周边的部分有数个切口， 可使缝合更平整， 减少了应力集中现象。
3、 瓣叶与内衬片均经过抗钙化处理， 可有效地防止瓣叶和内衬片过早发生钙 化。
4、 带瓣补片和带瓣管道自瓣叶上缘以上部分为单层， 无外衬支撑片 /管， 更加 易于流出道的缝合。
5、 修复心脏用带瓣补片自瓣叶上缘以下的部分为双层， 且外衬支撑管外具有 刚性支撑结构， 可以有针对加固右心室， 以消除右室收缩时易出现的反常博动。 附图说明

图 7为图 5中 A— A截面示意图。 具体实施方式
实施例 1
参阅图 2、 图 3， 本发明实施例修复心脏流出道用带瓣补片包括由经过化学改性 处理的牛心包片裁切制成的内衬片 1、 外衬支撑片 2和瓣叶 3， 内衬片 1上裁切有一半 圆弧形的狭缝 4 (参阅图 1 )， 瓣叶 3的下缘沿狭缝 4塞于内衬片 1、 外衬支撑片 2之间， 且瓣叶 3与内衬片 1之间具有一定的空间， 形成一瓣兜， 内衬片 1、 外衬支撑片 2和瓣 叶 3通过沿狭缝 4的两边缘的缝线 6缝合在一起。为使缝合平整，在瓣叶 3置于内衬片 1、 外衬支撑片 2之间的下缘部分， 裁切两个切口 5， 这样也可以有效地减少应力集中现 象。通常，带瓣补片自瓣叶 3上缘以上部分为单层，只具有内衬片 1，且长度约为 3.5〜 8.5cm, 补片自瓣叶 3上缘以下的部分均为双层， 具有内衬片 1和外衬支撑片 2， 其长 度约为 1.5〜6.5cm。
手术过程中， 只需将内衬片 1裁成所需形状， 置于流出道缺损部分， 并与流出 道缝合在一起， 大大节约了手术时间。 由于瓣叶 3置于内衬片、 外衬支撑片之间， 连接更为牢固， 可大大加强对血液的抗冲击能力。
实施例 2
参阅图 4、 图 5， 本发明实施例修复心脏流出道用带瓣管道包括由经过化学改 性处理的牛心包片裁切制成的内衬管片 7、 外衬支撑管片 8和三片瓣叶 9， 其展开 图 4中， 内衬管片 7上并排裁切有三个半圆弧形的狭缝 10， 瓣叶 9的下缘沿狭缝 10穿设于内衬管片 7和外衬管支撑片 8之间，且瓣叶 9贴合于内衬管片 7上， 内衬 管片 7、 外衬支撑管片 8和瓣叶 9通过沿狭缝 10的两边缘的缝线 11缝合在一起。 参阅图 5、 图 6、 图 7， 带瓣管道， 圆管形内衬管 7内径周长恰好为三个瓣叶 9上缘 长度之和， 三片瓣叶 9与内衬管 7不再贴合， 处于开启状态。 带瓣管道的内衬管 7 和外衬支撑管 8两端延伸有上、 下管道 12、 13， 下管道 13为内衬管 7和外衬支撑 管 8沿瓣叶下缘延长部分， 一般为 l〜2cm， 上管道 6为内衬管 1沿瓣叶上边缘延 长部分，一般为 8〜10cm，且外衬支撑管 8于瓣叶 9上缘处与内衬管 7通过缝线 11 缝合在一起。 瓣叶与内衬管、 外衬支撑管缝合时， 夹于内衬管、 外衬支撑管的瓣叶 下缘周边的部分有数个切口， 可使缝合更平整， 减少了应力集中现象。
手术过程中， 只需将瓣下管道 13边缘与右室流出道出口吻合， 瓣上管道与肺 动脉干吻合。 由于瓣叶 9置于内衬管与外衬支持管之间， 连接平整、 牢固， 可大大 增强抗血液冲击的能力。 为了加强带瓣管道的刚性， 在带瓣管道较长时， 可以在带 瓣管道外套设一医用高分子材料或金属材料制成的支撑网。
此外， 在 Ross手术中， 将肺动脉瓣连同部分肺动脉一起植入到主动脉瓣位置 后， 可以将本发明实施例的带瓣管道下管道部分与右心流出道出口吻合， 而将带瓣 管道上管道部分与肺动脉主干吻合以完成人工带瓣管道的置入。
