技术领域
本发明涉及医疗器械技术领域，特别涉及一种输送装置。
背景技术
腹主动脉瘤(AAA)是一种常见的主动脉疾病，流行病学研究显示，AAA在男性中的发病率为5％，但在80岁及以上患者中，发病率增长到10％，而且其瘤体破裂的风险较其他人群更高。据预测，到2020年，我国80岁以上人口将达到3000万，90岁以上的将超过1200万，在未来将有越来越多的高龄AAA患者需要接受治疗。
现有治疗腹主动脉瘤的主要方式包括传统的开放手术及腹主动脉瘤腔内修复术，两种方式各有优势。腹主动脉腔内修复术(EVAR)自20世纪90年代报道首例被用于治疗腹主动脉瘤以来，因其创伤小、手术及住院时间短、术后恢复快、围手术期病死率及并发症发生率低等优点，在短短的20年内迅速发展。
腹主动脉瘤腔内修复术最大的优势在于不需要开胸开腹，无需钳夹阻断血管，术中无内脏器官缺血，并发症少。然而最大的限制是内脏大动脉不能被覆盖，尤其是肠系膜上动脉和肾动脉，涉及肾动脉领域的腹主动脉瘤腔内修复仍是难点。
目前，采用“开窗支架型血管”对这类病人实施支架型血管的植入治疗,即在腹主动脉植入主体支架，在主体支架开设开窗结构，在开窗结构再安装分支支架血管，通往分支血管。对腹主动脉瘤实施腔内治疗所植入的支架型血管涉及腹腔干动脉、肠系膜上动脉和左右肾动脉四条分支动脉血管的重建。
现有技术中主体支架植入动脉血管后，然后需要重复一遍植入分支支架，而在植入分支支架之前，需要引导分支导丝经由主体支架的开窗结构到分支血管中，然后通过分支导丝引导分支支架经由主体支架的开窗结构到达分支血管中，然而引导分支导丝到达分支血管非常 困难，原因是分支导丝要穿过主体支架的开窗结构到达分支血管，分支导丝的远端对准并穿过主体支架的开窗结构非常困难，如何有效的减小分支导丝经由开窗结构到达分支血管的难度是当前医务人员和医疗研发人员必须共同解决的问题。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本申请说明书、权利要求书和附图中出现的术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，术语“第一”、“第二”和“第三”等是用于区别不同的对象，而并非用于描述特定的顺序。
为了描述清晰，以下输送装置靠近操作者的一端为近端，相对远离操作者的一端为远端；主体支架靠近心脏的一端为近端，相对远离心脏的一端为远端，输送装置和主体支架是通过不同的参照物定义近端和远端的。
本发明实施例提供一种输送装置，用于输送主体支架，在这里，主体支架是装载在输送装置内，所述主体支架上设有开窗结构，所述开窗结构的数量可以是一个，也可以是多个。请参见图1-图3，输送装置1000包括鞘芯组件100、外鞘管200、预埋导丝710。
具体地，在本实施例中，请参见图2及图4，所述鞘芯组件100包括内鞘芯110和外鞘芯管120，所述外鞘芯管120中空且套接在内鞘芯110上，所述外鞘芯管120可相对所述内鞘芯110轴向滑动。
在本实施例中，所述输送装置1000还包括引导头130和支架固定组件140，所述引导头130呈圆锥形，所述引导头130的远端为尖的，所述引导头130中心沿轴向形成中空通道131。内鞘芯110的远端与引导头130的近端固定连接，且内鞘芯110中空并与引导头130的中空通道131连通。邻近引导头130的近端设置所述支架固定组件140，所述支架固定组件140包括定位套142和固定锚143，所述固定锚143与外鞘芯管120的远端固定连接，所述固定锚143呈柱状结构，其上周向设有一圈均匀间隔分布的凸起，用于固定主体支架800近端处的裸支架840(请参见图11)，从而对主体支架800的近端进行定位，也即主体支架800的近端是套接在固定锚143上。所述定位套142的远端与所述引导头130注塑固定连接，所述定位套142中空，所述定位套142的近端部分套在固定锚143上。所述固定锚143与定位套142内壁之间存在限位间隙，主体支架800的近端部分位于该限位间隙中。
在本实施例中，所述外鞘管200中空并套接在鞘芯组件100外侧，具体套接在外鞘芯管120外侧，所述外鞘管200可相对所述外鞘芯管120轴向运动。所述外鞘管200与鞘芯组件100之间存在输送间隙210，具体地，所述输送间隙210位于外鞘管200与外鞘芯管120之间，这里所指的输送间隙210是指外鞘管200内壁与外鞘芯管120外壁之间的空间，所述固定锚143全部、定位套142近端部分位于所述输送间隙210中，所述输送间隙210的远端用于容纳收缩后的主体支架800，在这里，主体支架800是被施加外力强迫缩小体积以容纳到输送间隙210中，所述主体支架800近端的裸支架840定位在固定锚143的凸起上，所述主体支架800整体位于输送间隙210中。
在本实施例中，使用时，请参见图1、图2、图4，所述预埋导丝710由输送间隙210的近端进入并延伸到输送间隙210的远端。请参阅图11-图12，在主体支架800还未定位在固定锚143的凸起上时，预埋导丝710继续向前移动，所述预埋导丝710的远端从主体支架800的外侧经由开窗结构811进入到主体支架800的内侧，然后预埋导丝710的远端定位在主体支架800的内侧。其后，医疗人员将主体支架800收缩并放入在输送间隙210中，并回拉部分松懈的预埋导丝710，但预埋导丝710的远端不动，即，预埋导丝710的远端保持定位在 主体支架800内侧中的状态。其后，医疗人员将输送装置1000从动脉血管2000的一端2001放入到病人的动脉血管2000中。当输送装置1000中的主体支架800到达预定位置后，输送装置1000部分释放主体支架800，使主体支架800呈部分释放状态。当然，在本发明的其他实施例中，主体支架800也可以被完全释放。这时，位于主体支架800上的开窗结构811显露出来，医疗人员可以通过轴向或周向移动输送装置1000来调整开窗结构811等的位置，例如使开窗结构811对着分支血管2100，当然医疗人员也可以不调整。其后，医疗人员向输送装置1000的远端方向推预埋导丝710，使预埋导丝710向前移动，直到预埋导丝710从动脉血管2000的另一端2002伸出。其后，请参阅图13，医疗人员在动脉血管2000的另一端2002将分支导丝910与预埋导丝710相接，并通过预埋导丝710牵引分支导丝910。例如，预埋导丝710的远端可设有弯曲结构，通过预埋导丝710远端的弯曲结构勾住分支导丝910可实现预埋导丝710对分支导丝910的牵引。具体地，医疗人员向输送装置1000的近端方向拉预埋导丝710，通过预埋导丝710的引导，使分支导丝910穿过主体支架800的内侧，再从主体支架800的内侧经由主体支架800的开窗结构811穿出，并进入分支血管2100。当分支导丝910进入分支血管2100后，向动脉血管2000的所述一端2001后撤预埋导丝710，使预埋导丝710与分支导丝910脱离。例如，预埋导丝710远端的弯曲结构与分支导丝910的勾连被解除，从而使预埋导丝710与分支导丝910脱离。然后医疗人员从动脉血管2000的另一端2002推动分支导丝910，使分支导丝910可以继续往前伸入分支血管2100中。其后，请参阅图14，分支支架900可以通过分支导丝910的引导，经由主体支架800的开窗结构811到达分支血管2100中，并且分支支架900与主体支架800连通。
在本实施例中，通过预埋导丝710的引导，使所述分支导丝910可以很容易的穿过主体支架800的开窗结构811，其后继续推送分支导丝910，使分支导丝910很容易的进入到分支血管中，其后通过分支导丝910的引导，使分支支架900很容易通过主体支架800的开窗结构811到达分支血管中，从而有利于分支支架900的输送。
在本实施例中，请参见图1，所述输送装置1000近端设有第二锁定组件720，所述第二锁定组件720可用于锁止所述预埋导丝710的运动。在本实施例中，所述输送装置1000还包括控制手柄300、尾端固定件640、尾端滑道件650，所述控制手柄300与外鞘管200的近端连接，所述尾端固定件640与控制手柄300的近端固定连接，所述尾端滑道件650与所述尾端固定件640的近端固定连接，所述尾端滑道件650上设有所述第二锁定组件720，所述预埋导丝710穿过所述尾端滑道件650、尾端固定件640进入所述输送间隙210中。
具体说来，请参见图7，所述尾端滑道件650的内部沿轴向形成中空的尾部滑道651，所 述尾部滑道651与所述输送间隙210连通，所述预埋导丝710进入尾部滑道651内。所述第二锁定组件720包括丝固定件721、固定在尾部滑道件650上的固定凸环722和固定在尾部滑道651中的挡片723。所述预埋导丝710从挡片723和丝固定件721之间的间隙进入尾部滑道651中。其中，丝固定件721和固定凸环722之间可通过螺纹活动连接。当丝固定件721将预埋导丝710压紧在挡片723上时，预埋导丝710的运动被锁止，从而防止因失误将预埋导丝710牵拉至不合适的位置。
在本实施例中，请参见图1、图2，控制手柄300与外鞘管200连接，所述控制手柄300用于控制所述外鞘管200相对鞘芯组件100作轴向运动，具体用于控制所述外鞘管200相对所述外鞘芯管120作轴向运动，其中，在图1示意的图中左右方向为轴向。从而，通过控制手柄300控制所述外鞘管200作轴向运动，使收缩后位于输送间隙210中的主体支架800呈部分释放状态或者完全释放状态。在这里，请参见图9、图10，部分释放状态是指主体支架800近端部分被释放出来，释放部分的主体支架800不再受到外鞘管200的限制。请参见图11，完全释放状态是指外鞘管200不再对整个主体支架800起限制作用，也即此时主体支架800的外侧没有外鞘管200存在。在本实施例中，所述主体支架800是分步释放的，具体为：首先释放部分主体支架800，此时释放部分的主体支架800露出来(请参见图9、图10)，这里释放部分的主体支架800是位于主体支架800的近端这一侧，其余部分的主体支架800还在输送装置1000中，此时主体支架800呈部分释放状态；然后对主体支架800进行位置调整，当调整到位后，释放剩余部分的主体支架800，此时主体支架800被完全释放(请参见图11)，呈完全释放状态。另外，在本发明的其他实施例中，分步释放主体支架800的次数不限于两次，也可以是更多次。在本实施例中，所述开窗结构811在主体支架800呈部分释放状态时是位于主体支架800的释放部分上。
为了调节外鞘管200的轴向位置，在本实施例中，请参见图1、图2、图5，所述外鞘管200与鞘管接头220固定连接。在本实施例中，外鞘管200的近端外侧与鞘管接头220固定连接，当鞘管接头220沿轴向运动时，所述鞘管接头220会带动所述外鞘管200沿轴向运动。所述控制手柄300包括支撑主体310、固定手柄320和滑动手柄330，所述支撑主体310内部中空并且内部设有所述鞘管接头220。当对鞘管接头220施加轴向作用力时，所述鞘管接头220在支撑主体310内沿轴向运动以带动外鞘管200作轴向运动。所述固定手柄320安装在支撑主体310远端的外侧并且两者固定连接。所述滑动手柄330安装在支撑主体310外侧，所述滑动手柄330邻近固定手柄320的近端设置。所述滑动手柄330在支撑主体310外侧可转动并带动所述鞘管接头220沿轴向运动，也即通过滑动手柄330的转动转换为鞘管接头220 的轴向运动。
具体而言，所述支撑主体310上设有沿轴向延伸的长条孔311，所述支撑主体310的外侧在对应长条孔311处套设有主体牙块340。所述鞘管接头220包括接头主体222，和设于接头主体222上的抵接块221及远端凸块223，所述抵接块221和远端凸块223分别从长条孔311伸出并抵住主体牙块340的近端和远端，以用于限制主体牙块340相对鞘管接头220作轴向移动。所述滑动手柄330的内侧设有内螺纹，所述主体牙块340的外侧设有外螺纹，内螺纹与外螺纹啮合，当滑动手柄330转动时，主体牙块340在滑动手柄330的驱动下沿轴向运动，从而带动抵接块221和远端凸块223在长条孔311中沿轴向滑动，进而带动外鞘管200作轴向运动，从而可以使主体支架800处于部分释放状态或完全释放状态。
在本实施例中，所述滑动手柄330还可以在支撑主体310上沿轴向滑动，也即滑动手柄330可以相对固定手柄320沿轴向滑动。为了保持滑动手柄330的轴向位置，在本实施例中，请参阅图6，固定手柄320上嵌装有释锁按钮321，释锁按钮321向滑动手柄330一侧延伸出卡勾322，释锁按钮321的下方设有按钮支撑体323，所述按钮支撑体323固定在支撑主体310上，释锁按钮321与按钮支撑体323之间分别设有位置相对的定位柱324，两定位柱324上套设有驱动弹簧，驱动弹簧位于释锁按钮321与按钮支撑体323之间，以驱使卡勾322就位。所述卡勾322勾住滑动手柄330以使滑动手柄330紧邻固定手柄320设置，且阻止滑动手柄330在轴向上滑动。具体而言，滑动手柄330包括旋转盖332，所述旋转盖332位于滑动手柄330的远端设置。所述旋转盖332具有内翻边333，卡勾322可伸入并卡合在内翻边333处，内翻边333卡合卡勾322的一侧即可视为环形的定位槽，也即卡勾322是位于定位槽中，从而限制了卡勾322的轴向位置，又允许滑动手柄330相对于固定手柄320旋转。在本实施例中，旋转盖332上设有两道同心布置的减阻凸环334，所述减阻凸环334位于旋转盖332的远端侧壁上，通过减阻凸环334，固定手柄320与滑动手柄330之间由面接触变为线接触，大大减小两者间的接触面积，使其在相对运动时的阻力减小，释放过程更加平稳和准确。
为了防止主体支架800呈部分释放状态时，释放部分的主体支架800完全展开，从而导致释放部分的主体支架800与动脉血管2000紧贴(主体支架800完全释放后的直径一般要大于血管直径的10％左右)，进而导致主体支架800释放不准确时无法重新调整主体支架800位置的问题，在本实施例中，请参见图1-图3、图8，所述输送装置1000包括支架束缚组件400，支架束缚组件400用于当主体支架800呈部分释放状态时使释放部分的主体支架800未完全展开，以缩小释放部分的主体支架800的外径。这里释放部分的主体支架800是指未受 到外鞘管200限制住的主体支架800的部分，也即露出来的那部分主体支架800。在这里，释放部分的主体支架800未展开时的外径与释放部分的主体支架800完全展开时的外径之比小于或等于90％。由于释放部分的主体支架800未完全展开，外径较小，该部分主体支架800与血管不会紧贴，从而在主体支架800释放时的位置不准确时，例如主体支架800的周向对位不准确时，例如主体支架800上的开窗结构811(请参见图10)位置不准确，此时，由于释放部分的主体支架800与动脉血管2000之间不存在阻力，输送装置1000可以比较容易的带动主体支架800运动，例如转动或轴向运动，从而方便调整主体支架800位置，例如调整主体支架800的周向对位。当调整主体支架800到位后，控制手柄300可以操作外鞘管200沿轴向朝输送装置1000的近端运动，从而完全释放主体支架800，此时主体支架800完全展开，并与动脉血管2000紧贴。利用本实施例中的输送装置1000可方便调整主体支架800，有利于节省操作人员的时间和精力。在本实施例中，支架束缚组件400可以在主体支架800调整到位后即可使释放部分的主体支架800完全展开，也可以是主体支架800呈完全释放状态时再使主体支架800完全展开。另外，在本发明的其他实施例中，在主体支架800的轴向位置不准确时，操作者也可以通过操作输送装置1000对主体支架800的位置进行调整。
在本实施例中，所述支架束缚组件400包括至少一根控制丝410，在这里控制丝410的数量可以是一根、两根或者多根，所述控制丝410的材料可选自不锈钢丝，所述控制丝410由输送间隙210的近端进入并延伸到输送间隙210的远端。
请参见图11，所述主体支架800包括管状覆膜810和环形支撑架820，所述管状覆膜810上由近端向远端轴向设置有连接件830，所述连接件830周向间隔设置至少两排。较佳的，所述连接件830的近端位于管状覆膜810的近端，所述连接件830的远端位于管状覆膜810的中部，所述管状覆膜810上设有至少一个开窗结构811，所述开窗结构811位于管状覆膜810的近端和中部之间，当主体支架800呈部分释放状态时，此时管状覆膜810由近端向远端开始释放，但是一般不会超过管状覆膜810的中部位置，此时开窗结构811会位于释放部分的覆膜支架800上。所述控制丝410将至少两排所述连接件830束缚在一起以使主体支架800在周向上未完全展开，从而缩小了释放部分主体支架800的外径。在所述释放部分的主体支架800的外径小于血管直径时，可有利于调整主体支架800的位置，例如调整开窗结构811对着分支血管2100。较佳的，控制丝410束缚住的两排连接件830之间的周向长度可以减小释放部分的主体支架800的10％以上的外径，也即释放部分的主体支架800未展开时的外径与释放部分的主体支架800完全展开时的外径之比小于或等于90％。当主体支架800呈完全释放状态时支架束缚组件400解除对连接件830的束缚使主体支架800完全展开。本实 施例主体支架800的具体结构在本申请人在先申请的CN201711483955.7中作了详细的描述，在此通过引用将该文献的公开信息纳入本申请中。
在本实施例中，请参阅图1、图2、图8，所述支架束缚组件400还包括拉环420，所述拉环420与所述控制丝410的近端固定连接，方便手术时对控制丝410的操作。具体地，医疗人员通过拉环420向输送装置1000的近端施力可以解除控制丝410对主体支架800的束缚，从而完成主体支架800被束缚部分的释放。
为了增加器械使用的安全性，在本实施例中，所述输送装置1000还包括第一锁定组件500，所述第一锁定组件500用于锁定支架束缚组件400的运动以防止误解除控制丝410对主体支架800的束缚。在本实施例中，所述第一锁定组件500用于锁定拉环420的运动以防止误解除控制丝410对主体支架800的束缚。另外，在本发明的其他实施例中，所述第一锁定组件500还可以用于锁定控制丝410的运动以防止误解除控制丝410对主体支架800的束缚。在本实施例中，第一锁定组件500包括拉环固定件510、近释放旋盖520。拉环固定件510通过螺纹连接在尾端滑道件650(其后有描述)的近端，所述拉环固定件510设有定位拉环420的通孔、与近释放旋盖520配合的第一凹槽，所述近释放旋盖520可旋转的安装在拉环固定件510的远端，所述近释放旋盖520内侧远端设有L型凸起，所述L型凸起的长臂在周向上延伸，L型凸起的短臂由长臂的一端在轴向上朝远端延伸，所述L型凸起围成一个第二凹槽，拉环420的远端设置有向外延伸的第二凸起。当将拉环420插入通孔固定后，旋转近释放旋盖520，使第二凸起进入第二凹槽中，从而将拉环420锁定在该位置，此时拉环420不能带动控制丝410向近端方向移动，防止因失误解除对主体支架800的束缚，当旋转近释放旋盖520，使第二凸起从第二凹槽中出来时，可以操作拉环420，带动控制丝410向近端方向移动，可以解除对主体支架800的束缚。
在本实施例中，请参见图1-图3、图7，所述输送装置1000还包括推杆610和支撑管620，所述支撑管620位于外鞘管200和外鞘芯管120之间，也即支撑管620至少部分位于输送间隙210中，所述支撑管620起到增加支撑的作用。所述推杆610位于支撑管620和外鞘芯管120之间，所述推杆610的远端位于输送间隙210中。当控制手柄300控制外鞘管200相对鞘芯组件100作沿轴向向近端运动时，所述推杆610的远端用于抵住主体支架800以防止主体支架800向输送间隙210的近端移动，而且，所述推杆610也起到支撑的作用。另外，在本实施例中，所述推杆610的内部沿轴向形成贯通孔611，所述贯通孔可以用于控制丝410、预埋导丝710的通过。

需要说明的是，本说明书中的各个实施例均采用递进的方式描述，每个实施例重点说明的都是与其它实施例的不同之处，各个实施例之间相同相似的部分互相参见即可。对于装置实施例而言，由于其与方法实施例基本相似，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
