Description

输送设备及控制装置 技术领域
本发明涉及医疗器械技术领域，特别是涉及一种输送设备及控制装置。
背景技术
近几年，有学者开始尝试使用腔内隔绝术治疗主动脉疾病，相关的烟囱、开窗技术开始取得一些效果，其结果令人鼓舞。然而由于主动脉的弓部的解剖结构的特殊性和血流动力学的复杂性，将血管支架植入到体内需要利用输送设备进行输送。
传统的输送设备，一般采用相互套接的中空内管和外管，内管的中空部便于手术时导丝穿管，血管支架设置在内管和外管之间。由于传统的输送设备的结构缺陷，导致其血管支架的释放过程过于缓慢，手术时间偏长，不利于术后恢复，甚至会产生术后并发症。
发明内容
基于此，有必要提供一种输送设备及控制装置。该控制装置能够控制连接件的快速移动及缓慢移动，有利于实现血管支架释放的快慢控制。该输送设备采用了该控制装置，能够实现血管支架的快慢控制，有利于缩短手术时间。
其技术方案如下：
一方面，本申请提供一种控制装置，包括固定单元及活动单元，固定单元包括螺杆，螺杆设有容纳孔、以及与容纳孔相通的滑槽，容纳孔的孔深及滑槽的长度均沿螺杆的轴向方向设置；活动单元包括连接件、第一手柄、配合件及控制件，连接件设有第一连接体及与第一连接体固定的第二连接体，第一连接体设置于容纳孔中，第一连接体与螺杆滑动配合，第二连接体穿过滑槽与第一手柄转动连接，第一手柄呈中空状，且套设于螺杆的外侧，并可相对于螺杆移动，配合件设置于第一手柄内，配合件设有与螺杆相配合的内螺纹结构，控制件可动设置于第一手柄上；其中，当控制件处于第一位置时，内螺纹结构与螺杆分离；当控制件处于第二位置时，内螺纹结构与螺杆螺纹传动配合，且第一手柄能够带动控制件及配合件转动。
上述控制装置使用时，连接件、配合件及控制件集成到第一手柄上，连接件的第一连接体设置于容纳孔中，并与螺杆直接或间接滑动配合，同时第一手柄通过第二连接体与连接件转动连接，如此，第一手柄可带动连接件沿螺杆的轴向方向移动，同时可相对于连接件转动，第一连接体与输送管连接。具体地，应用于输送设备中，当需要快速释放血管支架时，控制件移动至第一位置，此时内螺纹结构与螺杆分离，使得配合件可相对于螺杆的轴向方向移动，即移动第一手柄可以带动控制件、配合件及连接件沿螺杆的轴向方向移动，利用连接件快速拉动输送管，使得血管支架被快速释放；当血管支架释放到一定程度时， 需要进行精细释放控制，此时，可移动控制件至第二位置，内螺纹结构与螺杆螺纹传动配合，使得配合件与螺杆螺接配合，此时旋转第一手柄可以带动配合件沿螺杆的轴线方向移动，即带动第一手柄、控制件及连接件沿螺杆的轴线方向移动，通过旋转第一手柄来控制连接件的移动距离，实现血管支架的精细释放。如此，该控制装置能够控制连接件的快速移动及缓慢移动，进而有利于实现血管支架释放的快慢控制。
下面进一步对技术方案进行说明：

当控制件处于第一位置时，挤压体与配合件错开，抵压体与凸起抵压配合，使得内螺纹结构与螺杆分离；
当控制件处于第二位置时，抵压体与凸起错开，挤压体挤压配合体，使得内螺纹结构与螺杆螺纹传动配合。

具体实施方式
为使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及具体实施方式，对本发明进行进一步的详细说明。应当理解的是，此处所描述的具体实施方式仅用以解释本发明，并不限定本发明的保护范围。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是旨在于限制本发明。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
如图1及图4至图7所示，提供一种控制装置，包括固定单元100及活动单元200。
如图3、图4及图7所示，固定单元100包括螺杆110，螺杆110设有容纳孔112、以及与容纳孔112相通的滑槽114，容纳孔112的孔深及滑槽114的长度均沿螺杆110的轴向方向设置。
如图3至图7所示，活动单元200包括连接件220、第一手柄210、配合件230及控制件240，连接件220设有第一连接体222及与第一连接体222固定的第二连接体224，第一连接体222设置于容纳孔112中，第一连接体222与螺杆110滑动配合，第二连接体224穿过滑槽114与第一手柄210转动连接，第一手柄210呈中空状，且套设于螺杆110的外侧，并可相对于螺杆110移动，配合件230设置于第一手柄210内，配合件230设有与螺杆110相配合的内螺纹结构232，控制件240可动设置于第一手柄210上。其中，当控制件240处于第一位置时，内螺纹结构232与螺杆110分离；当控制件240处于第二位置时，内螺纹结构232与螺杆110螺纹传动配合，且第一手柄210能够带动控制件240及配合件230转动。
上述控制装置使用时，连接件220、配合件230及控制件240集成到第一手柄210上，连接件220的第一连接体222设置于容纳孔112中，并与螺杆110直接或间接滑动配合，同时第一手柄210通过第二连接体224与连接件220转动连接，如此，第一手柄210可带动连接件220沿螺杆110的轴向方向移动，同时可相对于连接件220转动，第一连接体222与输送管400连接。具体地，应用于输送设备中，当需要快速释放血管支架时，控制件240移动至第一位置，此时内螺纹结构232与螺杆110分离，使得配合件230可相对于螺杆110的轴向方向移动，即移动第一手柄210可以带动控制件240、配合件230及连接件220沿螺杆110的轴向方向移动，利用连接件220快速拉动输送管400，使得血管支架被快速释放；当血管支架释放到一定程度时，需要进行精细释放控制，此时，可移动控制件240至第二位置，内螺纹结构232与螺杆110螺纹传动配合，使得配合件230与螺杆110螺接配合，此时旋转第一手柄210可以带动配合件230沿螺杆110的轴线方向移动，即带动第一手柄210、控制件240及连接件220沿螺杆110的轴线方向移动，通过旋转第一手柄210来控制连接件220的移动距离，实现血管支架的精细释放。如此，该控制装置能够控制连接件220 的快速移动及缓慢移动，进而有利于实现血管支架释放的快慢控制。
需要说明的是，“控制件240”与“配合件230”的配合形式可以有多种，只要能够实现内螺纹结构232与螺杆110的分离与传动配合之间进行切换即可。
具体到本实施例中，如图6、图7及图9所示，活动单元200还包括套管250，套管250套设于螺杆110的外侧，套管250设有通孔252，配合件230可转动设置于套管250上，且内螺纹结构232能穿过通孔252与螺杆110配合，配合件230还设有与内螺纹结构232沿圆周方向间隔设置的凸起234，凸起234朝远离螺杆110的方向设置，控制件240设有抵压体及与抵压体间隔设置的挤压体。当控制件240处于第一位置时，挤压体与配合件230错开，抵压体与凸起234抵压配合，使得内螺纹结构232与螺杆110分离；当控制件240处于第二位置时，抵压体与凸起234错开，挤压体挤压配合体，使得内螺纹结构232与螺杆110螺纹传动配合。
如此，配合件230可转动设置于套管250上，形成跷跷板结构。当控制件240移动至第一位置时，挤压体与配合件230错开，抵压体与凸起234抵压配合，使得内螺纹结构232翘起，而与螺杆110分离；当控制件240移动至第二位置时，抵压体与凸起234错开，挤压体挤压配合体，内螺纹结构232复位，使得内螺纹结构232与螺杆110螺纹传动配合。此过程中，只需沿螺杆110的轴向方向移动控制件240即可实现第一位置与第二位置的切换，实现内螺纹结构232与螺杆110的分离与传动配合之间进行切换。
在上述实施例的基础上，如图6及图7所示，一实施例中，控制件240可弹性复位设置于套管250上，在弹性作用力下，控制件240可自动复位至第二位置；挤压体与配合体之间设有斜面导入结构236。如此，在弹性作用力下，控制件240可自动复位至第二位置，使得配合件230与螺杆110螺接配合，进而旋转第一手柄210即可带动连接件220沿螺杆110的轴向缓慢移动，便于血管支架释放的精细控制。同时通过设置斜面导入结构236，便于将挤压体挤压配合体，使得内螺纹结构232与螺杆110螺纹传动配合。该斜面导入结构236可以设置于挤压体或/和配合体上，起到先导入，逐渐挤压的作用。
当然了，另一实施例中，控制件240包括第一按压部(未示出)及第二按压部(未示出)；当第一按压部下压至第一位置时，第二按压部处于非第二位置，抵压体与凸起234抵压配合，使得内螺纹结构232翘起，而与螺杆110分离；当第二按压部下压至第二位置时，第一按压部处于非第一位置，抵压体与凸起234错开，挤压体挤压内螺纹结构232，使得内螺纹结构232复位，而与螺杆110螺接配合。如此，利用按压原理亦可实现控制件240在两个位置之间进行切换。
该第一按压部及第二按压部可以利用分度销等现有技术实现。
再另一实施例中，配合件230可弹性复位设置于螺杆110上，控制件240设有插部(未示出)。当控制件240处于第一位置时，插部插入内螺纹结构232与螺杆110之间，使得内螺纹结构232与螺杆110分离；当控制件240处于第二位置时，插部与内螺纹结构232及螺杆110错开，配合件230在弹性作用力 下复位，使得内螺纹结构232与螺杆110螺纹传动配合。如此，利用插部与配合件230的自动复位，亦可实现内螺纹结构232与螺杆110的分离与传动配合之间进行切换。
该插部可移动插入内螺纹结构232与螺杆110之间，也可以按压插入内螺纹结构232与螺杆110之间，具体可根据实际需要进行选择。
在上述任一实施例的基础上，如图3所示，一实施例中，固定单元100还包括第二手柄120，第二手柄120固设于螺杆110上，第一手柄210能够相对于第二手柄120移动。如此，通过设置第二手柄120，便于操作者抓取第二手柄120进行第一手柄210上的相关操作，实现第一手柄210的移动及旋转。
在上述任一实施例的基础上，如图4、图8及图9所示，一实施例中，控制装置还包括调弯单元300，调弯单元300包括驱动件310及柔性牵引件320，驱动件310可动设置于第一手柄210，且驱动件310可随第一手柄210移动，柔性牵引件320的一端固定于驱动件310上。如此，柔性牵引件320的另一端与输送管400的自由端固定连接，该输送管400进入到主动脉的弓部时，使得驱动件310运动，带动柔性牵引件320牵引输送管400进行弯曲，使得输送管400能够血管支架能够顺利、安全地通过弯曲较大的主动脉的弓部，且能够克服输送血管支架过程中易伤害主动脉的弓部的问题，降低手术风险。
进一步地，一实施例中，驱动件310可相对于第一手柄210转动，驱动件310设有套设于螺杆110上的连接套312以及固定于连接套312的外侧的施力部314，柔性牵引件320的一端固定在连接套312上。如此，当需要进行调弯控制时，只需旋转施力部314，使得连接套312转动，进而带动柔性牵引件320收缩缠绕在连接套312上，使得输送管400弯曲，以便顺利通过血管弯曲部位。
或另一实施中，如图8及图9所示，驱动件310可相对于第一手柄210转动，驱动件310设有套设于螺杆110上的连接套312以及固定于连接套312的外侧的施力部314，连接套312设有外螺纹结构302，调弯单元300还包括与第一手柄210固定连接的第三手柄330、以及与外螺纹结构302螺接配合的螺套340，第三手柄330呈中空状，螺套340设置于第三手柄330内，且与第三手柄330滑动连接，柔性牵引件320的一端固定在螺套340上。如此，当需要进行调弯控制时，只需旋转施力部314，使得连接套312转动，进而带动螺套340沿连接套312的轴线方向移动，带动柔性牵引件320收紧，使得输送管400弯曲，以便顺利通过血管弯曲部位。
需要说明的是，该柔性牵引件320为牵引绳或牵引链条。
具体到本实施例中，该柔性牵引件320为牵引绳，有利于节省空间，使得输送设备的体积可以更小，特别是输送管400的体积更小，适用于微创手术。
在上述任一实施例的基础上，如图3所示，一实施例中，固定单元100还包括导杆130，导杆130固设于螺杆110内，第一连接体222设有与导杆130滑动配合的配合孔204。如此，通过导杆130与配合孔204的滑动配合，使得连接件220可相对于螺杆110滑动，使得连接件220的移动更加平稳。
进一步，一实施例中，导杆130设有流道(未示出)，固定单元100还包括与流道导通的导管140，导管140的一端固定在螺杆110上，并与外部导通。如此，可通过导管140向流道中注入所需试剂，该试剂经导管140、流道、配合孔204流入输送管400中，并从血管支架中流出，可以更好地进行治疗。
如图1至图3所示，一实施例中，还提供了一种输送设备，包括上述任一实施例中的控制装置，第一连接体222设有连接部202，还包括输送管400，输送管400的一端通过连接部202与连接件220固定连接。
该输送设备使用时，当需要快速释放血管支架时，控制件240移动至第一位置，此时内螺纹结构232与螺杆110分离，使得配合件230可相对于螺杆110的轴向方向移动，即移动第一手柄210可以带动控制件240、配合件230及连接件220沿螺杆110的轴向方向移动，利用连接件220快速拉动输送管400，使得血管支架被快速释放；当血管支架释放到一定程度时，需要进行精细释放控制，此时，可移动控制件240至第二位置，内螺纹结构232与螺杆110螺纹传动配合，使得配合件230与螺杆110螺接配合，此时旋转第一手柄210可以带动配合件230沿螺杆110的轴线方向移动，即带动第一手柄210、控制件240及连接件220沿螺杆110的轴线方向移动，通过旋转第一手柄210来控制连接件220的移动距离，实现血管支架的精细释放。该输送设备采用了该控制装置，能够实现血管支架的快慢控制，有利于缩短手术时间。
具体地，该输送设备与血管支架配合，可以应用于Stanford A型主动脉夹层的治疗。Stanford A型主动脉夹层(acute aortic dissection type A，简称AADA)是一种严重危及病人生命安全的灾难性疾病，其特点是起病突然，病情进展迅速，死亡率高。
