具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
在本发明中，在未作相反说明的情况下，使用的方位词如“内、外”是以治疗时人体为定义的，
如图1至图4所示，本发明提供一种导丝导引装置，以及使用该装置的导丝导引组件。其中导丝导引装置包括导引主体1，为了便于置入体内而不对人体造成损伤，优选地，导引主体1的截面为圆形，从而安全性更好。其中导引主体1可以使用聚四氟乙烯等材料制成，其轴向长度可以根据不同的手术要求而定。
其中为了实现本发明的目的，导引主体1内分别形成有主体导丝通道2和导丝导引通道3，主体导丝通道2和导丝导引通道3分别沿轴向贯穿导引主体1，并且导丝导引通道3的体内端开口和主体导丝通道2的体内端开口间隔设置。另外本发明提供的导丝导引组件包括上述导丝导引装置，以及用于从导丝导引通道3的体外端开口伸入并从体内端开口伸出的导丝捕捉器5。
因此，在本发明上述的技术方案中，导引主体1可以由穿过主体导丝通道2的主体导丝4置入体内血管中，并且可以通过导丝捕捉器5将待导引导丝，例如分支血管的分支导丝6引入导丝导引通道3内，并且由于与导丝导引通道3的体内端开口沿轴向间隔设置，因此可以使得待引导导丝可以在轴向上与主体导丝4相互错开地进入导丝导引通道3内，从而能够避免主体导丝4、分支导丝6等各类导丝之间相互缠绕的问题，进一步地通过导丝捕捉 器5可以便于将待引导的导丝引入导引主体1中，操作方便、实用性强。
其中本发明中使用导丝捕捉器5为本领域内常见部件，例如在本实施方式中，导丝捕捉器5可以是美国COOK公司生产的型号为
Figure PCTCN2016101706-appb-000001
4-Loop Vascular Retriever(血管内抓捕器)的捕捉器。在其他实施方式中，只要能够实现对导丝的捕捉器均应落在本发明的保护范围中。另外，本发明中使用的用于将导引主体1置入体内血管的主体导丝4可以是额外部件也可以是介入治疗中，例如血管支架置入系统的主体导丝。
其中为了导引更多的导丝，在本实施方式中，导丝导引通道3为多个，该多个导丝导引通道的体内端开口沿轴向间隔设置。这样可以保证手术中所有导丝均得到导引。作为一种实施例，导丝导引通道3为三个，以分别对应三个分支血管10中的分支导丝6。其中，本发明中具体的导丝导引通道3的数量可以根据手术中使用的导丝数量而定，例如三个、四根或更多。
另外，如图2所示，在本实施方式中，多个导丝导引通道3和主导丝通道2的体外端开口沿导引主体1的周向等间隔设置。从而使得从导引主体1引出的多个导丝能够整齐布置，从而便于连接至相应的体外端控制装置上。其中由于多个导丝导引通道3和主导丝通道2的体内端开口沿轴向间隔设置，因此部分导丝导引通道3在导引主体1内会呈弯曲状布置，由于各通道相互分隔，并且各导丝均具有柔性，因此在导引主体1内即使弯曲也不会影响导丝功能，同时也不会发生缠绕。
如图1所示，为了便于在体内端形成沿轴向间隔的各个端口，在本发明的第一实施方式中，导引主体1的体内端端面11形成为斜切面，主导丝通道2和导丝导引通道3沿该斜切面布置以在轴向上间隔开。其中在导丝导引通道3为多个的情况下，多个导丝导引通道3和主体导丝通道2的体内端开口可以沿斜切面的中心线直线布置，其中在导引主体1的截面为圆形时，斜切面为椭圆型，因此多个体内端开口可以沿椭圆的长轴布置。另外，多个体 内端开口也可以根据需要异线布置。通过这种斜切面的设置，不仅便于布置多个通道口，而且可以便于导引主体1在体内的移动，移到引导作用。另外，斜切面的布置是的多个通道口在沿轴向设置的同时还能够沿径向或切向布置，从而使得多个导丝在进入导引主体1前能够更方便地相互隔开，而不会发生缠绕。
如图3所示，在本发明的第二实施方式中，不用于图1中的整体斜切面方式，本实施方式中的导引主体1的体内端端面11形成为呈台阶结构的多个斜切面，该多个斜切面平行，主导丝通道2和导丝导引通道3分别形成在不同的斜切面上。具体地，斜切面可以为四个，也同时形成一个主导丝通道2和三个导丝导引通道3的四个体内端开口。这种多个斜切面的布置方式同样可以实现多个通道口相互隔开的目的，并且保证导丝在进入导引主体1之前不发生缠绕。
在本发明的实施方式中，为了方便加工制造导丝导引装置，优选地，主导丝通道2和导丝导引通道3分别由管路8形成并包覆在导引主体1内。如图1所示，通过虚线显示了一条管路8。即，通过包覆材料将多个独立的管路8进行包覆固定既可以形成本发明提供的导丝导引装置。在其他可能的实施方式中，在工艺允许的情况下，也可以通过在导引主体1上一体成型出通孔而制造加工制造出本发明提供的导丝导引装置。
如图4所示，在本发明的第三实施方式中，不同于第一和第二实施方式的是，形成主导丝通道2和导丝导引通道3的管路8分别从导引主体1的体内端端面凸出。即，多个通道的体内端开口不形成在导引主体1的体内端端面上，而是随管路8的体内端开口自由设置，并且长短各异，这样也可以实现各导丝的引入并防止导丝缠绕。
在本实施方式中，为了便于操作，导引主体1上设置有沿轴向延伸的显影标示线7。其中显影标示线7可以在手术中实时观看，这样，通过显影标 示线7的位置以及变形程度来为手术操作提供依据，使得手术更加精确。在本发明提供的第二实施方式中，显影标示线7包括整体段71和多个分体段72，整体段71布置在导引主体1的外侧壁上，多个分体段72分别布置在台阶结构的多个台阶面上并可以形成在相邻体内端开口之间的连线上，该台阶面位于相邻的斜切面之间且相互平行。这样，除整体段71的作用，通过多个分体段72还可以辅助标识各个通道口的位置，使得操作更加精确快捷。
另外，优选地，导丝导引通道3和/或主体导丝通道2的体内端开口呈喇叭形，该喇叭形为向各通道的外侧张开的结构，该喇叭形的设计可以通过大口段引入导丝，而通过小口径段稳定地导引导丝，使得操作更加方便。从而便于各导丝的引入。
另外，为了便于引导多个导丝，在本实施方式中，主体导丝通道2的体内端开口接近椭圆形的长轴的一端设置，例如导引主体1的最内端，这样各导丝导引通道3可以沿长轴依次布置。另外在本实施方式中，主导丝通道用于引导穿过主体血管9的主体导丝4，导丝导引通道用于引导穿过连接在该主体血管上的分支血管10的分支导丝6。这样，主体导丝4可以贴近主体血管9的侧壁布置，而斜切面可以面向连接在主体血管9上的多个分支血管10的开口，从而可以更加有利于各分支导丝6向导引主体1的引入。使得各导丝的排列更加有序整齐，避免发生缠绕。
下面对本发明提供的导丝导引方法进行描述，其中该导丝导引方法使用本发明提供的上述导丝导引组件，其中包括：a.将主体导丝4置入到预定位置；具体地置入主体导丝4的方式与例如血管支架等介入手术中的导丝置入方式相同。b.将主体导丝4穿入主体导丝通道2并将导引主体1沿主体导丝4置入体内；这样可以使得主体导丝4起到导引导引主体1的作用。c.将导丝捕捉器5穿入导丝导引通道3并伸出体内端开口以捕捉到待导引导丝6；在这一步骤中，可以事先将导丝捕捉器5置入导丝导引通道3中，待导引主 体1运动到指定位置后再伸出，也可以在导引主体1运动到制动位置后，再置入导丝捕捉器5。最后d.通过拉动导丝捕捉器5将待导引导丝6引入导丝导引通道3。这样，可以将各个手术用的导丝，尤其主体导丝4和分支导丝6均通过导引主体1进行导引而延伸到体外，其中各个导丝的体外端可以延伸出导丝导引通道3的体外端开口从而与各个对应的操作装置相连。这样，通过置入的导引主体1能够使得手术中使用的各种导丝在体内的延伸以较好的顺序进行排列，而不会发生导丝相互缠绕等问题，使得手术顺利进行。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于上述实施方式中的具体细节，在本发明的技术构思范围内，可以对本发明的技术方案进行多种简单变型，这些简单变型均属于本发明的保护范围。
另外需要说明的是，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合，为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。
此外，本发明的各种不同的实施方式之间也可以进行任意组合，只要其不违背本发明的思想，其同样应当视为本发明所公开的内容。
