端部执行器械、端部执行装置、输送装置、及装配盒 技术领域
本发明属于医疗器械领域，具体涉及一种端部执行器械、端部执行装置、输送装置、及装配盒。
背景技术
临床上常采用内镜配合夹子机械压迫止血的方法进行治疗。目前临床上所用的端部执行装置分为夹子与装置分离式(简称为“分离式端部执行装置”)，或夹子与装置一体式(简称为“一体式端部执行装置”)。

本发明的有益效果在于：
第一组：第1至第10为第一组方案
1、端部执行器械包括端部执行装置和输送装置。端部执行装置包括夹子、以及弹性部，弹性部设有套接孔，弹性部的外周面设有限位凸；夹子用于结扎。
输送装置包括鞘管和芯轴，鞘管设有通道，芯轴设于鞘管的通道内，芯轴可以在鞘管内向近端或远端移动。本文所述“近端”、“远端”，是指沿着端部执行器械的长度方向(因为要通过输送装置将端部执行装置送入人体进行结扎，输送装置通常为长线形)、或者是沿着端部执行器械进入人体的方向，朝向操作人员所在的一侧为“近端”，朝向伸入人体进行治疗的一侧为“远端”；“近端”包括近端的端面以及近端端面附近的一部分，“远端”包括远端的端面以及远端端面附近的一部分。某某部分的“近端”或者“远端”，是指，某某部分朝向操作人员所在的一侧为某某部分的“近端”，某某部分朝向伸入人体进行治疗的一侧为某某部分的“远端”，某某部分的“近端”包括该部分近端的端面以及近端端面附近的一部分，某某部分的的“远端”包括该部分远端的端面以及远端端面附近的一部分。
鞘管的内壁设有限位凹，弹性部与限位凹配合用于将端部执行装置与输送装置连接，当鞘管套设于弹性部外时，连接端头可伸入或退出套接孔：当连接端头伸入套接孔，则弹性部向外扩张，限位凸伸入限位凹，此时限位凸被限位凹限制，鞘管和端部执行装置连接在一起；当连接端头退出套接孔，则弹性部回弹，限位凸退出限位凹，鞘管和端部执行装置的连接关系解除。
连接端头伸入或退出套接孔，就可以控制将鞘管和端部执行装置连接或者解除鞘管和端部执行装置的连接，只要端部执行装置和输送装置使用配套的弹性部和连接端头，就可以采用一个输送装置对应使用多个端部执行装置，输送装置可以重复使用；同样型号的端部执行装置也可以采用不同的输送装置，使得端部执行器械适用性、通用性大幅提升。
其中，弹性部的弹性是用于在连接端头退出套接孔后，使弹性部回弹、限位凸退出限位凹，从而将端部执行装置与鞘管的连接关系解除，弹性部不限于使用弹性材料，也可以使用非弹性材料，只要能够使弹性部回弹、限位凸退出 限位凹就可以。
2、限位凸为至少两个，限位凹可以是一个，限位凹也可以是与限位凸配合的多个，每个限位凸伸入对应的限位凹内，获得有多个连接点，使端部执行装置和鞘管的连接关系更牢固。优选的，多个限位凸对称设置，使其受力均匀。
3、端部执行装置还包括连接管，夹子安装于连接管，连接管设有通道，弹性部包括弹性环，弹性环设于连接管的通道内，弹性环设有套接孔和限位凸，套接孔与连接管的通道连通，连接管的管壁设有限位孔，限位孔与限位凸对应。
当鞘管套设于连接管外时，鞘管套设于弹性环外，向远端推动芯轴，带动连接端头向远端移动，连接端头伸入套接孔内，弹性环向外扩张，使限位凸穿过限位孔伸入限位凹，使连接管与鞘管相连接。
4、弹性环设有缺口。缺口可以增加弹性环被挤压扩张的幅度，使限位凸与限位凹的连接牢固；同时，也使得连接端头可以更轻松地套入套接孔内。
5、夹子的近端伸入连接管的通道，夹子的近端设有卡接孔，卡接孔与连接管的通道连通，连接端头的远端设有卡接部，卡接部与卡接孔卡扣配合，卡接部包括凹槽部和膨大部，凹槽部位于膨大部与连接端头之间，膨大部的最大宽度大于凹槽部的最小宽度，膨大部的最大宽度大于卡接孔的最小宽度。
其中，膨大部的最大宽度是指横截面上的最大宽度，例如，如果膨大部为圆柱体的横截面为圆形，则膨大部的最大宽度为圆形的直径，如果膨大部的横截面为长方形，则膨大部的最大宽度为长方形对角线的长度。
膨大部的最大宽度大于凹槽部的最大宽度，使得膨大部和凹槽部构成“台阶”，当推动膨大部向远端运动使膨大部穿过卡接孔时，凹槽部卡扣在凹槽部内，完成连接端头与夹子的卡扣连接。此时，推动芯轴向远端运动就会带动夹子向远端运动，当夹子伸出连接管足够长时，夹子张开；拉动芯轴向近端运动就会带动夹子向近端运动，当夹子进入连接管的通道足够长时，夹子闭合。
夹子闭合后，继续拉动芯轴向近端运动就会带动夹子向近端运动，当所述卡接部退出所述卡接孔，所述夹子与所述芯轴解除连接。卡接孔的边沿可以被膨大部挤压变形、或者破坏、或者断裂，但此时已完成连接端头与夹子的分离，不影响实际使用。
优选的，通过设计合适的卡接孔形状与直径、膨大部形状与宽度、卡接孔周边的材料，可以使膨大部与卡接孔无损地反复卡接或接触卡接。
6、膨大部的远端设有导向部，导向部的横截面从近端至远端逐渐减小。导向部的横截面是指导向部在垂直或近似垂直膨大部向远端运动的方向上截面，导向部的横截面逐渐变小变化使得导向部的外表面形成导向斜面，可以引导膨大部更顺利地伸入卡接孔内。
7、夹子包括至少两个夹片，夹片的近端设有尾夹部，至少两个尾夹部之间设有间隙，至少两个尾夹部之间的间隙构成卡接孔。由夹片本身构成卡接孔，结构简单。通常夹片为扁平的片状，优选的，夹片的近端向垂直或近垂直扁平面的方向弯折构成L钩，两个夹片的L钩之间的间隙构成卡接孔、两个夹片的L钩相对于卡接孔对称设置，两个夹片的L钩为卡接孔的边沿。采用这种方式在扁平状的夹片上设置卡接孔，结构简单，生产效率高。
8、夹子还包括连接销，夹片的近端设有锁定凸和连接孔，连接销穿设于连接孔内，当至少两个夹片被连接管压迫闭合，至少两个夹片的近端沿连接销滑动、并向相互远离的方向弹开，锁定凸伸入锁定凹。当夹片的近端靠近连接管的远端时，夹片的远端相互远离，这时夹片张开；当夹片的近端靠近连接管的近端时，夹片的远端被连接管压迫闭合，夹片的近端向相互远离的方向张开，锁定凸伸入锁定凹，从而将夹片锁定在连接管上，不让夹片相对连接管运动，保持夹片闭合的状态，防止结扎后夹子松开。
优选的，夹片本身设有弧度，夹片的弧度使夹片可以自动张开或闭合。
优选的，连接管的远端设有阻挡部，阻挡部位于两个所述夹片之间，阻挡部可以挡住连接销，防止夹片从连接管的远端开口脱出。
9、限位凸的侧面设有限位部，限位部位于连接管的通道内。当弹性部被挤压向外扩张时，限位部可以抵住限位凹外、或者限位部抵住限位孔附近，从而防止弹性部过度张开。
10、弹性环由至少两个半环组成，至少两个半环围成套接孔，半环设有限位凸。半环可以直接套设于连接管的通道内，使限位凸与限位孔对准。半环可以是1/2环、1/3环、或者其他形状的环，只要能在连接端口撤出套接孔时自动 回弹，使端部执行装置与鞘管的连接解除就可以。
第二组：第11至第12为第二组方案
11、一种端部执行器械，与上述1所述类似。但是，不同之处在于：端部执行器械包括：端部执行装置和输送装置。
端部执行装置包括连接管、以及安装于连接管的夹子，夹子用于结扎；连接管设有通道，连接管的内壁设有限位凹；
输送装置包括鞘管和芯轴，鞘管设有通道，芯轴设于鞘管的通道内，芯轴的远端设有连接端头，鞘管的远端设有弹性部，弹性部设有套接孔，套接孔与鞘管的通道连通，弹性部的外周面设有限位凸；
当弹性部伸入连接管的通道时，连接端头可伸入或退出套接孔：当连接端头伸入套接孔，则挤压弹性部向外扩张，限位凸伸入限位凹；当连接端头退出套接孔，则弹性部回弹，限位凸退出限位凹。连接端头伸入或退出套接孔，就可以控制将鞘管和连接管连接或者解除鞘管和连接管的连接，只要端部执行装置和输送装置使用配套的连接管、弹性部和连接端头，就可以采用一个输送装置对应使用多个端部执行装置，输送装置可以重复使用；同样型号的端部执行装置也可以采用不同的输送装置，使得端部执行器械适用性、通用性大幅提升。
其中，弹性部的弹性是用于在连接端头退出套接孔后，使弹性部回弹、限位凸退出限位凹，从而将连接管与鞘管的连接关系解除，弹性部不限于使用弹性材料，也可以使用非弹性材料，只要能够使弹性部回弹、限位凸退出限位凹就可以。
12、限位凸为至少两个，限位凹可以是一个，限位凹也可以是与限位凸配合的多个，每个限位凸伸入对应的限位凹内，获得有多个连接点，使端部执行装置和鞘管的连接关系更牢固。优选的，多个限位凸对称设置，使其受力均匀。
13、鞘管的远端设有弹性环，弹性环设于鞘管的通道内，弹性环为弹性部，弹性环设有套接孔和限位凸，鞘管的管壁设有限位孔，限位孔与限位凸对应。当弹性部伸入连接管时，连接管套设于弹性环外，向远端推动芯轴，带动连接端头向远端移动，连接端头伸入套接孔内，弹性环向外扩张，使限位凸穿过限位孔伸入限位凹，使连接管与鞘管相连接。
14、弹性环设有缺口。缺口可以增加弹性环被挤压扩张的幅度，使限位凸与限位凹的连接牢固；同时，也使得连接端头可以更轻松地套入套接孔内。
15、夹子的近端伸入连接管的通道，夹子的近端设有卡接孔，卡接孔与连接管的通道连通，连接端头的远端设有卡接部，卡接部与卡接孔卡扣配合，卡接部包括凹槽部和膨大部，凹槽部位于膨大部与连接端头之间，膨大部的最大宽度大于凹槽部的最小宽度，膨大部的最大宽度大于卡接孔的最小宽度。其中，膨大部的最大宽度是指横截面上的最大宽度，例如，如果膨大部为圆柱体的横截面为圆形，则膨大部的最大宽度为圆形的直径，如果膨大部的横截面为长方形，则膨大部的最大宽度为长方形对角线的长度。
膨大部的最大宽度大于凹槽部的最大宽度，使得膨大部和凹槽部构成“台阶”，当推动膨大部向远端运动使膨大部穿过卡接孔时，凹槽部卡扣在凹槽部内，完成连接端头与夹子的卡扣连接。此时，推动芯轴向远端运动就会带动夹子向远端运动，当夹子伸出连接管足够长时，夹子张开；拉动芯轴向近端运动就会带动夹子向近端运动，当夹子进入连接管的通道足够长时，夹子闭合。
夹子闭合后，继续拉动芯轴向近端运动就会带动夹子向近端运动，当所述卡接部退出所述卡接孔，所述夹子与所述芯轴解除连接。卡接孔的边沿可以被膨大部挤压变形、或者破坏、或者断裂，单此时已完成连接端头与夹子的分离，不影响实际使用。
优选的，通过设计合适的卡接孔形状与直径、膨大部形状与宽度、卡接孔周边的材料，可以使膨大部与卡接孔无损地反复卡接或接触卡接。
16、膨大部的远端设有导向部，导向部的横截面从近端至远端逐渐减小。导向部的横截面是指导向部在垂直或近似垂直膨大部向远端运动的方向上截面，导向部的横截面逐渐变小变化使得导向部的外表面形成导向斜面，可以引导膨大部更顺利地伸入卡接孔内。
17、夹子包括至少两个夹片，夹片的近端设有尾夹部，至少两个尾夹部之间设有间隙，至少两个尾夹部之间的间隙构成卡接孔。由夹片本身构成卡接孔，结构简单。通常夹片为扁平的片状，优选的，夹片的近端向垂直或近垂直扁平面的方向弯折构成L钩，两个夹片的L钩之间的间隙构成卡接孔、两个夹片的 L钩相对于卡接孔对称设置，两个夹片的L钩为卡接孔的边沿。采用这种方式在扁平状的夹片上设置卡接孔，结构简单，生产效率高。
18、夹子还包括连接销，夹片的近端设有锁定凸和连接孔，连接销穿设于连接孔内，当至少两个夹片的远端被连接管压迫闭合，至少两个夹片的近端沿连接销滑动、并向相互远离的方向弹开，锁定凸伸入锁定凹。
当夹片的近端靠近连接管的远端时，夹片的远端相互远离，这时夹片张开；当夹片的近端靠近连接管的近端时，夹片的远端被连接管压迫闭合，夹片的近端向相互远离的方向张开，锁定凸伸入锁定凹，从而将夹片锁定在连接管上，不让夹片相对连接管运动，保持夹片闭合的状态，防止结扎后夹子松开。
优选的，夹片本身设有弧度，夹片的弧度使夹片可以自动张开或闭合。
优选的，连接管的远端设有阻挡部，阻挡部位于两个所述夹片之间，阻挡部可以阻挡夹片，从而避免夹片从连接管的远端脱出。
19、限位凸的侧面设有限位部，限位部位于鞘管的通道内。当弹性部被挤压向外扩张时，限位部可以抵住限位凹外、或者限位部抵住限位孔附近，从而防止弹性部过度张开。
20、弹性环由至少两个半环组成，至少两个半环围成套接孔，半环设有限位凸。半环可以直接套设于连接管的通道内，使限位凸与限位孔对准。半环可以是1/2环、1/3环、或者其他形状的环，只要能在连接端口撤出套接孔时自动回弹，使端部执行装置与鞘管的连接解除就可以。
21、权利要求21至29所述的端部执行装置与上述第一组方案的端部执行装置相同，权利要求30至33所述的输送装置与上述第一组方案的输送装置相同，各结构的有益效果类似，在此不再赘述。
22、权利要求34至36所述的端部执行装置与上述第二组方案的端部执行装置相同，权利要求37至44所述的输送装置与上述第二组方案的输送装置相同，各结构的有益效果类似，在此不再赘述。
23、一种用于将权利要求21至29任一项的端部执行装置与权利要求34至36任一项的输送装置进行装配、或者将权利要求30至33任一项的端部执行装置与权利要求37至44任一项的输送装置进行装配的装配盒，装配盒包括盒体， 盒体设有端部执行装置容纳室、以及鞘管容纳室，端部执行装置容纳室用于容纳端部执行装置，鞘管容纳室用于容纳鞘管，鞘管容纳室一端与端部执行装置容纳室连通、另一端设有开口。将端部执行装置设于端部执行装置容纳室内(包括将端部执行装置的全部设于端部执行装置容纳室内，或者将端部执行装置的其中一部分例如端部执行装置的近端设于端部执行装置容纳室内)，将鞘管的远端设于鞘管容纳室内(不限于将鞘管的全部设于鞘管容纳室内，或者将鞘管的其中一部例如鞘管的远端设于鞘管容纳室内)，从鞘管容纳室的开口将鞘管推挤使鞘管套设于弹性部外、或者连接管套设于弹性部外，鞘管容纳室引导鞘管与端部执行装置的近端对接，利于将鞘管和端部执行装置连接。
24、端部执行装置容纳室包括夹子容纳室、以及与夹子容纳室连通的连接管容纳室，夹子容纳室用于容纳夹子，连接管容纳室用于容纳连接管。
25、夹子容纳室与连接管容纳室之间设有定位凸，定位凸用于抵靠连接管的远端。避免连接管向夹子容纳室滑动，也为连接管提供支撑，在移动连接段都完成端部执行装置与鞘管的连接、与分离时避免连接管移动。
26、夹子容纳室容纳张开状态的夹子。夹子的卡接孔位于套接孔的前端，连接端头穿过套接孔后，卡接部才能与卡接孔卡接，所以夹子预先呈张开状态，此时卡接孔靠近连接管的远端，先将连接端头插入弹性部的套接孔，使端部执行装置与鞘管连接，使连接端头继续向远端运动，使卡接部与卡接孔卡扣连接，此时芯轴与夹子已连接，拉动芯轴向近端移动，带动夹子收纳入连接管内，然后可以从鞘管容纳室的开口将输送装置、端部执行装置一起抽出，此时端部执行装置与输送装置的连接已完成、芯轴与夹子的连接已完成，操作芯轴就能操作夹子进行结扎，至此完成了端部执行装置与输送装置的装配。
27、盒体包括相连接的容纳段和夹紧段，容纳段设有端部执行装置容纳室，夹紧段设有鞘管容纳室，夹紧段受挤压力时，鞘管容纳室发生变形用于夹紧鞘管。使用时，可以用手夹紧夹紧段，稳住鞘管，使鞘管与连接管始终处于对接的位置，利于将鞘管与连接管对接。
28、夹紧段包括至少两个夹瓣，至少两个夹瓣之间围成鞘管容纳室，夹瓣受挤压力时，至少两个夹瓣向相互靠近的方向聚拢用于夹紧鞘管。夹紧段利用 夹瓣来实现夹紧功能。夹瓣张开时，将鞘管插入鞘管容纳室内，然后对夹瓣施加挤压力，使夹瓣夹紧鞘管。

具体实施方式
下面对本发明作进一步详细说明，但本发明的实施方式不限于此。
实施例一
端部执行器械包括端部执行装置100、输送装置200、以及控制装置300，如图1所示。
如图2至16所示，端部执行装置100包括夹子、连接管120以及弹性部450，夹子安装于连接管120，连接管120设有通道，夹子的近端可以从连接管120的远端进出连接管120的通道，夹子包括两个近端相连接的夹片110，夹片110的远端设有结扎齿113，连接管120的远端设有阻挡部123，阻挡部123位于两个夹片110之间，可以阻挡夹片110或连接销130，防止夹片110从连接管120的远端脱出。当夹片110的远端靠近连接管120的远端，夹片110被连接管120压迫闭合。
弹性部450包括弹性环400，弹性环400设有套接孔430，弹性环400的外周面设有限位凸410，弹性环400设于连接管120的通道内，弹性环400设有套接孔430和限位凸410，套接孔430与连接管120的通道连通，连接管120的管壁设有限位孔121，限位孔121与限位凸410对应，限位凸410可以穿过或退出限位孔121。
输送装置200包括鞘管210和芯轴220，鞘管210设有通道，芯轴220设于鞘管210的通道内，芯轴220的远端设有连接端头230，鞘管210包括鞘管本体和端盖250，端盖250设有限位台阶270，限位台阶270与鞘管本体的远端端面一起构成限位凹240。
控制装置300包括手柄310和滑动部320，手柄310和鞘管210连接，滑动部320和芯轴220连接，滑动部320可以相对于手柄310滑动，向远端或近端滑动滑动部320，可以带动芯轴220相对于鞘管210向远端或近端运动。
当鞘管210套设于弹性部450外时，连接端头230可伸入或退出套接孔430：当连接端头230伸入套接孔430，则弹性部450向外扩张，限位凸410伸入限位凹240，使连接管120和鞘管210相连接；当连接端头230退出套接孔430，则弹性部450回弹，限位凸410退出限位凹240，使连接管120和鞘管210相的连接关系解除。
当弹性环400受到从套接孔430施加的挤压力(图10所示的力F的方向)时，弹性部450向外(图10所示的实线箭头方向)扩张；当弹性部450受到从套接孔430施加的挤压力撤销时，则弹性部450回弹(图10所示的虚线箭头方向)。弹性环400设有缺口440。缺口440可以增加弹性环400被挤压扩张的幅度，使限位凸410与限位凹240的连接牢固；同时，也使得连接端头230可以更轻松地套入套接孔430内。弹性环400的横截面形状不限，优选的，采用如图11所示的(a)至(h)的形状。
本实施例中，限位凹240是鞘管210内壁上的槽，鞘管210包括鞘管本体和设在在鞘管本体远端的端250，端盖250设有限位台阶270，设置端盖250来制作限位凹240，生产工艺简单，但不限于此，也可以，也可以在鞘管210的侧壁上开盲孔或通孔或槽，构成限位凹240，或者在鞘管210的内壁设置向鞘管210中心轴凸起的台阶，台阶与鞘管210的内壁之间构成限位凹240，限制限位凸410从鞘管210远端滑出。
本实施例中，如图9、10、12所示，连接管120的近端设有定位环150，连接管120的内壁设有台阶，台阶和定位环150将弹性环400固定于连接管120的近端。但不限于此，也可以直接将弹性环400放在连接管120的通道内使弹性环400的限位凸410伸入限位孔121，或者在连接管120内设置其他将安装弹性环400的定位结构。
限位凸410的侧面设有限位部420，限位部420位于连接管120的通道内。当弹性部450被挤压向外扩张时，限位部420可以抵住限位凹240外、或者限位部420抵住限位孔121附近，从而防止弹性部450过度张开。
夹片110的近端设有尾夹部112，两个尾夹部112之间设有间隙，两个尾夹部112之间的间隙构成卡接孔115，卡接孔115与连接管120的通道连通。由夹 片110本身构成卡接孔115，结构简单。通常夹片110为扁平的片状，优选的，夹片110的近端向垂直或近垂直扁平面的方向弯折构成L钩，如图16所示，两个夹片110的L钩之间的间隙构成卡接孔115、两个夹片110的L钩相对于卡接孔115对称设置，两个夹片110的L钩为卡接孔115的边沿。采用这种方式在扁平状的夹片110上设置卡接孔115，结构简单，生产效率高。
连接端头230的远端设有卡接部，卡接部与卡接孔115卡扣配合，卡接部包括凹槽部232和膨大部231，凹槽部232位于膨大部231与连接端头230之间，膨大部231的最大宽度(图14所示D1)大于凹槽部232的最小宽度(图14所示D2)，膨大部231的最大宽度大于卡接孔115的最小宽度。
夹子还包括连接销130，夹片110的近端设有锁定凸111和连接孔114，连接销130穿设于连接孔114内，当两个夹片110被连接管120压迫闭合，两个夹片110的近端沿连接销130滑动、并向相互远离的方向(如图16箭头所示方向)弹开，锁定凸111伸入锁定凹122。
当夹片110的近端靠近连接管120的远端时，夹片110的远端相互远离，这时夹片110张开；当夹片110的近端靠近连接管120的近端时，夹片110的远端被连接管120压迫闭合，夹片110的近端向相互远离的方向张开，锁定凸111伸入锁定凹122，从而将夹片110锁定在连接管120上，不让夹片110相对连接管120运动，保持夹片110闭合的状态，防止结扎后夹子松开。优选的，夹片110本身设有弧度，夹片110的弧度使夹片110可以自动张开或闭合。
膨大部231的远端设有导向部233，导向部233的横截面从近端至远端逐渐减小，如图4、14所示。导向部233的横截面是指导向部233在垂直或近似垂直膨大部231向远端运动的方向上截面，导向部233的横截面逐渐变小变化使得导向部233的外表面形成导向斜面，可以引导膨大部231更顺利地伸入卡接孔115内。
夹子闭合后，继续拉动芯轴220向近端运动就会带动夹子向近端运动，当所述卡接部退出所述卡接孔115，所述夹子与所述芯轴220解除连接。卡接孔115的边沿可以被膨大部231挤压变形、或者破坏、或者断裂，但此时已完成连接端头230与夹子的分离，不影响实际使用。
优选的，通过设计合适的卡接孔115形状与直径、膨大部231形状与宽度、卡接孔115周边的材料，可以使膨大部231与卡接孔115无损地反复卡接或接触卡接。
本实施例中，端部执行装置100和输送装置200可以反复装卸，当端部执行装置100对人体进行结扎后，端部执行装置100从输送装置200脱离，输送装置200可以回收使用，可以将端部执行装置100和输送装置200分开生产，再将端部执行装置100和输送装置200装配起来使用，如图17至23所示，为将端部执行装置100和输送装置200装配的方法，本实施例中使用装配盒500进行装配，装配成功率高、操作简单，可以提高装配效率，也便于医务人员快速培训使用。
如图17所示，装配盒500包括盒体，盒体包括相连接的容纳段510和夹紧段520，容纳段510设有端部执行装置100容纳室，端部执行装置100容纳室包括夹子容纳室511、以及与夹子容纳室511连通的连接管120容纳室，夹子容纳室511用于容纳夹子，连接管120容纳室用于容纳连接管120。
夹子容纳室511容纳张开状态的夹子。
夹子容纳室511与连接管120容纳室之间设有定位凸513，定位凸513用于抵靠连接管120的远端。
夹紧段520设有鞘管210容纳室，鞘管210容纳室用于容纳鞘管210，鞘管210容纳室一端与端部执行装置100容纳室连通、另一端设有开口。
夹紧段520受挤压力(如图19箭头方向)时，鞘管210容纳室的最小宽度缩小。
如图19所示，夹紧段520包括至少两个夹瓣522，至少两个夹瓣522之间围成鞘管210容纳室，夹瓣522受挤压力时，至少两个夹瓣522向相互靠近的方向聚拢、鞘管210容纳室的最小宽度减小。
装配时：
(1)将端部执行装置100放入端部执行装置100容纳室内，夹子以张开状态容纳于夹子容纳室511内，连接管120容纳于连接管120容纳室，连接管120的远端抵靠定位凸513，如图18、19所示。
(2)将鞘管210从鞘管210容纳室近端开口插入，使鞘管210套设于连接管120的近端外，此时鞘管210套设于弹性环400外，如图20所示，并挤压夹紧部的夹瓣522(如图20箭头所示)，使夹瓣522将鞘管210位置固定，以便后续操作。
(3)推动滑动部320带动芯轴220向远端运动，是连接端头230伸入套接孔430内，挤压限位以图21所示箭头方向外张，限位凸410穿过限位孔121伸入限位凹240内，使鞘管210与连接管120连接；继续使芯轴220向远端运动，使卡接部的膨大部231穿过卡接孔115，卡接孔115边沿卡住凹槽部232，使芯轴220与夹子连接，此时移动芯轴220就能带动夹子向远端或近端运动，如图21所示。
(4)拉动芯轴220向近端运动，带动夹子向近端运动，夹子逐渐收入连接管120内，夹子闭合，此时夹片110不再阻碍夹子从夹子容纳室511中脱出，然后继续向近端拉动芯轴220，直至将端部执行装置100、输送装置200从装配盒500的鞘管210容纳室的近端开口中脱出，如图21所示。
至此，装配完成。
其中，夹子容纳室511可以开放或不开放，从灭菌的角度考虑，优选的，出厂时端部执行装置100密封于夹子容纳室511内。
实施例二
实施例二与实施例一的区别在于：
如图24至26所示，弹性部450与连接管120为是一体的，连接管120为管状，在连接管120近端的管壁上制作弹性部450，连接管120的通道就是套接孔430，当连接端头230伸入套接孔430时，弹性部450上的限位凸410被向外挤压伸入鞘管210限位凹240，使鞘管210与连接管120连接，当连接端头230退出套接孔430，弹性部450充当弹臂的作用，自动回弹，使限位凸410退出限位凹240，连接端与鞘管210的连接关系解除。
本实施例中，端部执行装置100和输送装置200的装配与实施例一类似，可以适用实施例一的装配盒500。
实施例三
实施例三与实施例一的区别在于：
