在本申请的描述中，需要说明的是，术语“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
如图1所示，本申请实施例提供了一种介入瓣膜系统1的保护及收入辅助装置，介入瓣膜系统1包括瓣膜11和输送系统，通过输送系统内的连接装置将瓣膜11固定设置在输送系统的远端杆体12的第一端。
保护及收入辅助装置包括可以相对配合的第一保护件2和第二保护件3，还包括第三保护件4。第一保护件2位于靠近远端杆体12的一侧，且第一保护件2对瓣膜11形成半包围。第三保护件4用于固定且套设在远端杆体12上。
在保护状态，第一保护件2与第三保护件4配合在第一位置(参照图7)，在瓣膜11收入辅助状态，第一保护件2与第三保护件4配合在第二位置(参照图8)。第二位置相对于第一位置远离瓣膜11。
在本实施例中，第一保护件2整体为中空且两端开通的结构，第二保护件3也整体为中空且两端开通的结构。第一保护件2和第二保护件3扣合后能形成 容纳腔；在运输过程中，第一保护件2能对瓣膜11起到保护作用，但是第一保护件2与第二保护件3配合后，对瓣膜11起到的保护作用更好。
第三保护件4为中空且两端开通，与第一保护件2能互相配合，在运输过程中，第一保护件2和第三保护件4配合在第一位置，使第一保护件2对瓣膜11进行保护，第三保护件4对远端杆体12进行保护。当运输完成后，需要对瓣膜11进行收入时，第一保护件2和第三保护件4配合在第二位置，使第二保护件3能够对瓣膜11产生挤压，瓣膜11变形，伴随远端杆体12的收入动作，将瓣膜11完全收入到远端杆体12中，形成使用状态。
作为一种具体的实现方式，如图2和图3所示，第一保护件2整体为大致的漏斗形状，包括依次设置第一大径部21、第一锥形部22和第一小径部23。其中，第一大径部21可以具有一定的锥度，第一小径部23为圆柱筒状，第一锥形部22位于第一大径部21和第一小径部23之间。
如图4所示，第二保护件3整体为大致的漏斗形状，包括依次设置第二大径部31、第二锥形部32和第二小径部33。其中，第二大径部31具有与第一大径部21相同的锥度，从而与第一大径部21相配合。第二小径部33为圆柱筒状，第二锥形部32位于第二大径部31和第二小径部33之间。第二锥形部32的内壁面形成锥形面34，用于对瓣膜11形成挤压。
第一大径部21和第二大径部31对接扣合后形成保护瓣膜11的容纳腔，第一小径部23则与第三保护件4相配合。
如图5和图6所示，优选地，第三保护件4包括套筒41和锁定件42。套筒41的第一端与第一小径部23套接固定。远端杆体12包括粗杆121和细杆122，套筒41套在粗杆121上，锁定件42与粗杆121和细杆122之间的第一台阶123配合，并与套筒41的第二端套接固定。这样，套筒41能够对介入瓣膜系统1中远端杆体12的一部分(粗杆121)进行保护，而锁定件42能将套筒41锁止。
进一步地，套筒41包括主体411和握持部412，主体411与握持部412之间设置有第二台阶415。在瓣膜11收入状态，第二台阶415处作为第二位置。当需要收入瓣膜11时，使第一保护件2相对于套筒41的外壁滑动至第二位置，由于第二保护件3与第一保护件2扣合固定，因此第二保护件3在滑动过程中会对瓣膜11发生挤压，从而使瓣膜11发生变形，以收入到粗杆121的内部。
优选地，握持部412的外表面设置有压花，以方便操作者握持。
套筒41上还优选地设置有透气孔413，通过设置该透气孔413来对介入瓣 膜系统1灭菌。透气孔413可以是长条状，也可以是圆孔或其他异形孔，沿着套筒41的轴线开设在套筒41上。本领域技术人员可以理解的是，透气孔413的数量可以是一个，也可以是多个，可以根据实际情况进行设定。
上文已述，当运输状态时，第一保护件2与第三保护件4配合在第一位置。第一位置的实现方式可以通过如下方式实现：套筒41的外壁开设有限位槽414，第一小径部23的内壁设置有限位块24(参照图3)，限位块24与限位槽414配合在第一位置。当运输状态完成，需要进入收入状态时，使第一保护件2沿着第三保护件4的套筒41滑动至第二状态，从而使第二保护件3对瓣膜11发生挤压，瓣膜11收入至套筒41的内部。
具体地，限位槽414包括沿套筒41的轴线方向开设的竖槽和垂直于竖槽的横槽，限位块24与横槽远离竖槽的端部配合时，配合位置作为第一位置。
在运输状态时，限位块24与横槽的最远端配合锁定，当在现场进行手术前的收入时，旋转第一保护件2，使限位块24沿着横槽滑动至竖槽内，此时第一保护件2与套筒41脱扣。然后推动第一保护件2沿着竖槽滑动到套筒41与锁定件42之间的第二台阶415处，受到第二台阶415的限位达到第二位置。在第一保护件2沿着竖槽滑动的过程中，第二保护件3对瓣膜11产生挤压，瓣膜11变形后收入到套筒41内。
如图7所示，为第一保护件2与第三保护件4配合在第一位置的状态，此状态为运输状态，装置起到保护的作用。如图8所示，为第一保护件2与第三保护件4配合在第二位置的状态，此状态为收入状态，装置起到瓣膜11收入的作用。
如图6所示，锁定件42可以包括上固定部421和下固定部422。上固定部421和下固定部422的结构可以相同也可以不同，本实施例以二者结构相同为例进行说明，上固定部421包括第一半锥形管421a和第一头部421b，下固定部422包括第二半锥形管422a和第二头部422b。第一半锥形管421a和第二半锥形管422a相互扣合，扣合后从套筒41的第二端伸入到套筒41中。套筒41的握持部412远离主体411的一端设置有锥形孔416(参照图5)，第一半锥形管421a和第二半锥形管422a扣合后的外壁面为锥形，与锥形孔416配合。
第一头部421b和第二头部422b相互扣合，扣合后套在细杆122上，并与粗杆121和细杆122之间的第一台阶123相配合。
上固定部421和下固定部422之间的固定方式有多种，优选地，第一头部 421b上设置有上限位孔和/或上限位柱。第二头部422b上设置有下限位孔422c和/或下限位柱422d，上限位孔与下限位柱422d配合，下限位孔422c与上限位柱配合。
上述的限位孔可以是盲孔，限位柱可以是圆柱状，顶部带有倒角，二者配合实现上固定部421和下固定部422的固定。
最后需要拆下整个装置时，抽出锁定件42，其他部件失去紧固力，沿与抽取锁定件42相反的方向抽出其他部件即可。
本领域技术人员可以理解的是，锁定件42与套筒41之间的锁定配合方式并不仅限于上述配合方式，还可以通过螺纹连接或卡扣连接等其他方式。
以上仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
