Abstract
本发明公开了一种用于静脉瓣膜重建术的器具，其特征在于它由塑料薄膜或片材经裁剪制成的纺轴形补片和神经纤维剥离器构成，所述的纺轴形补片在常态下为塑料薄膜或片材的扁平制品，在其长边上带有对称的V形缺口，短边则为对称的槽形线，手术时将其植于静脉血管的外壁上，经缝合构成两端呈喇叭口状的空心器管；所述的神经纤维剥离器为一U形塑料件，其前端呈突起状，中间有孔，边角应倒圆，抛光达镜面光泽，用于剥离和保护静脉血管上的神经纤维。纺轴形补片与神经剥离器在手术中应配套使用，可大幅度提高手术的安全性与治愈率。
Description
技术领域
本发明涉及移植到人体静脉血管壁上的空心或管状器管，尤其涉及用于静脉瓣膜重建术的器具。
背景技术
上世纪80年代，美国学者凯斯诺(Kistner)首先提出下肢原发性深静脉瓣膜功能不全导致血液倒流，表现为下肢静脉曲张小腿溃烂这种疾病之后，许多学者相继采用各种瓣膜修复术用于医疗实践中。虽然取得了一定的效果，但只能在原有瓣膜功能不全的基础上加以修复，而对无瓣症或者瓣膜严重受损者却无法实施。据医学统计，下肢静脉疾病的发病率为10％，已成为危害人们健康的较大病种。
发明人通过十余年医学临床科研和实践，创造了一种用于静脉瓣膜重建的手术配套器具。该器具分作A、B两部分，A部是用聚四氟乙烯片材料裁剪成纺轴形补片，缝合固定于静脉壁外，使其两端能扩张呈喇叭口纺轴柱状。这种结构可阻止血液倒流，并可避免重建瓣膜血管两端血流形成涡流或湍流，从而防止血栓形成。B部则是用聚四氟乙烯制成的表面光滑的U形器件，用于剥离和保护神经束。据解剖学所知，神经纤维与血管伴行，疏松的结缔组织将它们连结在一起，手术之时，务必将其剥离并加以保护，为血管手术腾出操作空间。对于神经纤维的任何损伤都会给患者造成比原发病更为严重的伤害。从这个意义上说，纺轴形补片与神经纤维剥离器必须配套包装使用，缺一不可。
发明内容
本发明的目的在于提供一种用于静脉瓣膜重建的互为配套的手术器具。本发明的技术解决方案是这样实现的：
一种用于静脉瓣膜重建术的器具，其特征在于它由塑料薄膜或片材经裁剪制成的纺轴形补片和神经纤维剥离器构成，所述的纺轴形补片的正常状态为塑料薄膜或片材的扁平制品，在其长边上带有对称的V形缺口，短边则为对称的槽形线，手术时将其植入静脉血管外壁上，经缝合构成两端呈喇叭口状的空心器管；所述的神经纤维剥离器为一U形塑料件，其上端呈突起状，中间有孔，周边棱角应倒圆，达到镜面光泽，用于剥离和保护静脉血管上的神经纤维。
与现有技术比较，本发明的优点是显而易见的，主要表现在通过纺轴形补片移植到静脉血管壁上构成了一个空心器管，作为人造血管瓣膜代用品或取代物，有效地纠正静脉血液的返流，弥补了瓣膜功能不全的缺憾，大大提高了相应病变的治愈率。
附图说明
本发明提供了4幅附图，其中
图1是本发明的纺轴形补片的展开图；
图2是图1的工作状态下的结构示意图；
图3是本发明神经纤维剥离器的结构示意图；
图4是图3的左视图。
图中，1、槽形边线，2、V形缺口，3、喇叭口，4、缝合线，5、悬吊孔。
具体实施方式
如图1至图4所示。一种静脉瓣膜重建术的器具，其特征在于该器具由A、B两部分构成，其中A部为纺轴形补片，B部分为神经纤维剥离器，A、B两部分应配套使用。纺轴形补片的常态为聚四氟乙烯片材的扁平制品，其长边带有对称的V形缺口，其短边为带槽形的边线，该边线在手术中应缝合，套装在静脉血管壁上，构成一个空心器管，两端是喇叭口状。所述空心器管的内径应视具体情况确定。与纺轴形补片同时配套使用的神经纤维剥离器应辅助静脉瓣膜重建术的完成，其功能是首先剥离与静脉血管伴行的神经束，同时将其置于该剥离器的U形槽中，且通过剥离器前端的通孔悬吊于固定架上。
