本申请涉及医疗器械技术领域，尤其涉及一种封堵器、用于输送所述封堵器的封堵器紧锁系统，以及封堵器紧锁系统的紧锁方法。
背景技术
腔内封堵器(如左心耳封堵器、血管塞、滤器等)的输送系统通常包括输送鞘管装置、扩张装置、装载装置、推送装置等几个部分。输送鞘管装置和扩张装置先建立好通道，然后撤出扩张装置，通过推送装置将封堵器收入装载装置，接着连接输送鞘管装置与装载装置，通过推送装置将封堵器导入输送鞘管内，直至将封堵器输送至靶向位置。随着导管介入治疗方法的发展，研发出了各种不同的腔内封堵器，然而，现有的腔内封堵器通过输送器释放后在紧锁过程中普遍存在可靠性和简便性较差等问题，这可能会影响封堵器的使用寿命以及封堵效果，并增加发生并发症的风险。
申请内容
本申请针对现有技术的缺陷，提供一种紧锁的可靠性高、且操作简单方便的封堵器、封堵器紧锁系统及封堵器紧锁系统的紧锁方法。
为解决上述技术问题，本申请提供一种封堵器包括第一封堵部及第二封堵部，所述第一封堵部的远端沿所述第二封堵部方向设置连接栓，所述连接栓的侧壁设置第一外螺纹，所述第二封堵部的近端设置凸出部，所述凸出部开设通孔，所述凸出部的侧壁设置第二外螺纹，所述第一外螺纹的螺纹方向与所述第二外螺纹的螺纹方向相反，所述连接栓的近端能穿过所述通孔螺接于螺母。
本申请还提供一种封堵器紧锁系统,其包括封堵器及推送装置，所述推送装置包括第一控制组件、第二控制组件及推送组件，所述推送组件包括推送管以及套设所述推送管内的所述推送件，所述推送管远端的内壁设置可与所述第二外螺纹相配合连接的第二内螺纹，所述第一控制组件可驱动所述推送件往复滑动，以带动与所述推送件可拆卸连接的所述连接栓的近端抵接或远离螺母，所述第一控制组件可驱动所述推送管转动，所述第二控制组件能驱动推送管转动，所述第一外螺纹和所述螺母的紧固方向与所述凸出部和所述推送管的紧固方向相反。
本申请还提供一种封堵器紧锁系统的紧锁方法，包括紧锁前处理、紧锁处理和紧锁后处理；其中，所述紧锁前处理包括:
提供封堵器、推送装置和鞘管可调弯装置，所述封堵器包括螺母以及相互连接的第一封堵部和第二封堵部，所述第一封堵部远端设置连接栓，所述第二封堵部近端设置凸出部，推送装置包括推送管和推送件，鞘管可调弯装置包括鞘管；
将所述螺母与所述推送管的远端卡合处理、所述连接栓与所述推送件螺纹连接处理以及所述凸出部与所述推送管螺纹连接处理，驱动所述推送件将所述封堵器拉伸处理后置于鞘管内并释放所述封堵器；

请参阅图1，本申请提供一种封堵器紧锁系统，包括封堵器10、鞘管可调弯装置20、扩张器30、设置于鞘管可调弯装置20近端的装载器40、以及设置于装载器40的近端的推送装置60。鞘管可调弯装置20包括壳体21、近端置于壳体21内的鞘管23，以及用于调弯鞘管23的可弯曲远端的调节机构25。装载器40包括装载管42、设置于装载管42的近端的密封座44，以及与密封座44径向连通的三通阀46，装载管42的远端可插接于鞘管23内。推送装置60可推送封堵器10，推送装置60包括具有容置空间的壳体61、部分置于壳体61内的第一控制组件64及部分套接于壳体61的第二控制组件67、以及推送组件68，推送组件68包括推送件682(图4)，推送件682呈细长结构，推送件682的部分置于壳体61内。
如图2及图3所示，封堵器10包括第一封堵部11、第二封堵部15，以及设置于第一封堵部11与第二封堵部15之间且同时连接第一封堵部11和第二封堵部15的腰部18。第一封堵部11的远端沿第二封堵部15方向设置连接栓112，即连接栓112沿轴向朝第二封堵部15延伸，连接栓112的侧壁开设第一外螺纹113，第二封堵部15的近端设置凸出部152，凸出部152开设通孔153，具体的，通孔153沿封堵器10的轴心线开设于凸出部152，并贯通凸出部152的近端面与远端面。凸出部152的侧壁设置第二外螺纹154，第一外螺纹113的螺纹方向与第二外螺纹154的螺纹方向相反，即第一外螺纹113的螺纹旋入方向与第二外螺纹154的螺纹旋入方向相反，连接栓112的近端能穿过通孔153螺接于螺母，螺母抵接于凸出部152的近端面，连接栓112的螺纹有效长度大于或等于螺母的螺纹有效长度。连接栓112近端面的中部轴向开设螺孔115，螺孔115用于可拆卸地连接于推送件682的远端，具体的，螺孔115的内壁设置第一内螺纹，推送件682的远端螺接于第一内螺纹。
如图1、图3、图4至图7所示，推送组件68包括推送件682、活动地套设于推送件682外的推送管684，以及定位于推送管684远端内的螺母689。推送件682的远端可拆卸地连接于封堵器10的连接栓112，推送管684远端的内壁设置对应凸出部152的第二外螺纹154的第二内螺纹6842。第一控制组件64能驱动推送件682在推送管684内沿轴向往复滑动，以带动连接栓112抵接或远离螺母689的螺孔；第二控制组件67包括转动机构，转动机构能驱动推送管684转动，并带动螺母689转动使连接栓112螺接于螺母689。由于连接栓112和螺母689的紧固方向，与凸出部152的第二外螺纹154和推送管684的第二内螺纹6842的紧固方向相反，在连接栓112螺接于螺母689的过程中，凸出部152的第二外螺纹154与推送管684的第二内螺纹6842分离。
本申请中的封堵器紧锁系统的封堵器10包括设置在第二封堵部15远端的连接栓112，以及设置 于第二封堵部15近端的凸出部152，连接栓112的侧壁开设第一外螺纹113，凸出部152的侧壁设置第二外螺纹154，且第一外螺纹113的螺纹方向与第二外螺纹154的螺纹方向相反。封堵器紧锁系统的推送装置60包括第一控制组件64、第二控制组件67及推送组件68，推送组件68包括推送件682及推送管684，推送件682的远端可拆卸地连接于连接栓112的近端，推送管684的远端内壁设置对应第二外螺纹154的第二内螺纹6842，第一控制组件64能驱动推送件682轴向滑动，带动连接栓112的近端抵接或远离螺母689，第二控制组件67能驱动推送管684转动。由于连接栓112和螺母689的紧固方向与凸出部152和推送管684的紧固方向相反，因此，当连接柱112螺接于螺母689时，凸出部152与推送管684分离。
本申请提供的封堵器紧锁系统中，由于封堵器10在释放时连接栓112近端与螺母689连接固定，且螺母689抵顶于凸出部152的近端面，使得封堵器10释放后，能够通过旋紧在连接栓112上的螺母689，将封堵器10紧锁至靶向位置(比如一破口)，有利于封堵器10保持轴向长度，从而保持较佳的轴向与径向尺寸，以及较佳的封堵形态，避免封堵器10在血流的冲刷下变形甚至从病变位置脱落。因此，本申请中的封堵器10紧锁的可靠性高，能提高封堵器10的封堵效果，减少发生并发症的风险，增长了封堵器10的使用寿命；另外，连接栓112近端旋入螺母689的过程中，同时还能实现凸出部152的第二外螺纹154与推送管684的第二内螺纹6842的分离，即实现封堵器10的近端与推送管684的分离，简化了封堵器10脱离推送装置60的步骤。封堵器紧锁系统中，通过操作推送装置60能同时实现将封堵器10紧锁至靶向位置和封堵器10与推送管684的分离，使用方便，操作简单。
具体的，第一封堵部11的远端设置第一收紧件110，第二封堵部15的近端设置第二收紧件150，第一收紧件110和第二收紧件150位于封堵器10的轴心方向。第一收紧件110包括置于第一封堵部11的远端的外接套111以及连接于外接套111的连接栓112；第二收紧件150包括设置于第二封堵部15的近端的内接套151以及连接于内接套151的凸出部152。第一封堵部11和第二封堵部15是由金属丝编织而成具有内部空间的双层圆盘孤面结构，第一封堵部11和第二封堵部15内分别可以设置阻流膜。金属丝的远端汇聚定位于外接套111与连接栓112远端之间，金属丝的近端汇聚定位于内接套151与凸出部152之间。外接套111与连接栓112之间的金属丝可以采用焊接、卡接等固定方式，具体地，外接套111可以是两端开口的圆筒，金属丝的远端焊接于圆筒的内侧，连接栓112的远端端口沿径向设置凸面，凸面的直径大于圆筒的直径，连接栓112近端穿过圆筒且凸面卡和于圆筒的远端端面，另外，外接套111也可以是其近端往远端方向设置内腔的结构，连接栓112的远端固定于内腔内，金属丝焊接于外接套111和连接栓112之间，本实施例采用的是后一种结构；内接套151与凸出部152之间的金属丝也可以采用焊接、卡接等固定方式。连接栓112远端径向凸设定位盘116，定位盘116可以呈圆环状、方形等，定位盘116的远端面轴向凸设凸柱117，在封堵器10的紧锁过程中(即连接栓112近端旋入螺母689的过程中)，连接栓112往近端方向拉伸，当作用于连接栓112的作用力较大时，可能将与连接栓112固定的由金属丝编织而成的第一收紧件110拉入靶向位置的破口，使第一封堵部11的边缘翘起而形成类喇叭状结构，第一封堵部11翘起后不能对破口形成夹持力，影响对破口的封堵效果，而连接栓112靠近远端在径向方向上设置的定位盘116在连接栓112拉动第一封堵部11靠近破口时能起到阻挡作用，可以确保第一封堵部11位于假腔内且不会被连接栓112拉入破口，防止第一封堵部11边缘的翘起，确保第一封堵部11和第二封堵部15对破口形成良好的夹持作用，外接套111卡接于凸柱117，金属丝的远端定位于定位盘116与外接套111之间，内接套151和外接套111可以选用钢套。
在其他实施例中，封堵器10可以省略内接套151及外接套111，金属丝的远端汇聚定位于连接栓112远端并采用焊接定位，金属丝的近端汇聚定位于凸出部152的远端并采用焊接定位。
本实施例中，内接套151是两端开口的筒体，凸出部152也是两端开口的筒体，内接套151的内径大于凸出部152的外径，内接套151可以设置于第二封堵部15的内部或外部，内接套151套接于凸出部152，金属丝的近端位于内接套151的内壁与凸出部152的侧壁之间。优选的，内接套15位于第二封堵部15的内部，凸出部152的远端延伸至第二封堵部15的内部，内接套151套接于凸出部152的远端，金属丝的近端内折后定位于内接套151的内壁与凸出部152远端的侧壁之间。内接套151设置于第二封堵部15的内部，封堵器10在紧锁后可以减少第二收紧件150轴向凸出第二封堵部15的长度，能降低术后并发症的风险。
连接栓112的近端沿轴向朝近端延伸，在连接栓112没有与螺母689锁固之前，连接栓112位于封堵器10的内部，且连接栓112的近端通过封堵器10的腰部18。本实施例中，第一外螺纹113开设在连接栓112的近端侧壁，第二外螺纹154开设在凸出部152的近端侧壁。当第一外螺纹113为左旋螺纹时，第二外螺纹154为右旋螺纹；当第一外螺纹113为右旋螺纹时，第二外螺纹154为左旋螺纹。
请一并参阅图4至图7，推送组件68为钢缆组合，推送件682是具有良好的弹性的钢缆，推送管 684是具有良好的弹性的钢缆管，钢缆可活动地插接于钢缆管内。推送管684包括主体段6841及设置于主体段6841的远端的延伸段6843，螺母689可卡合并脱离于延伸段6843的内部，第二内螺纹6842位于延伸段6843远端的内壁，第二内螺纹6842可与凸出部152的第二外螺纹154相匹配。当封堵器10与推送组件68连接时，延伸段6843和凸出部154的螺纹紧固方向与连接栓112和螺母689的紧固方向相反，且延伸段6843和凸出部154的螺牙等于或多于螺母689的螺牙，延伸段6843和凸出部154的螺距等于或大于螺母689的螺距，以使连接栓112的近端延伸出螺母689的近端面。
推送件682远端的侧壁设置与连接栓112的螺孔115相匹配的第三外螺纹6822，即，螺孔115的内壁的第一内螺纹与第三外螺纹6822螺纹连接，推送件682的远端能活动地穿过设置于延伸段6843内的螺母689及延伸段6843。具体的，推送件682的远端面中部轴向凸设柱状的连接杆6821，连接杆6821的外径小于推送件682近端部分的外径，第三外螺纹6822位于连接杆6821远端的侧壁。
在推送管684中，主体段6841的外径小于延伸段6843的外径，主体段6841的内径小于延伸段6843的内径，螺母689可抵接于主体段6841的远端端口6845。延伸段6843近端的内壁开设卡合槽6846，螺母689能可卡合并脱离卡合槽6846内，卡合槽6846能防止螺母689在推送管684内转动，螺母689可以在延伸段6843内沿轴向滑动。具体的，卡合槽6846是在延伸段6843近端的内壁径向规则内凹形成，卡合槽6846可卡合螺母689，螺母689可以为如六角螺母，卡合槽6846是对应六角螺母的六边形凹槽，即卡合槽6846的径向横截面为六边形。因此，当螺母689卡合于卡合槽6846内时，螺母689相对于推送管684不能转动，但螺母689在延伸段684内轴向滑动，且螺母689与远端端口6845抵接。
请参照图1，扩张器30为细长的圆柱状结构，扩张器30的远端直径逐渐减小形成类圆锥状结构，内部还可设置通道(未示出)，通道供细丝通过。具体的，扩张器30包括扩张杆32及设置于扩张杆32的近端的连接部35，扩张杆32的远端直径逐渐减小形成类圆锥状结构，类圆锥状结构方便扩张杆32插入鞘管23内。在手术过程中，需先将扩张器30组装至鞘管可调弯装置20内，以组成扩张组件。
请一并参阅图8及图9，鞘管23设置可弯曲远端，且鞘管23的近端置于壳体21内。具体的，鞘管23包括可弯曲远端及主体段233，可弯曲远端包括位于远端的固定段232及连接于固定段232与主体段233之间的弹性段235，主体段233的近端置于壳体21内。调节机构25包括置于壳体21内的调节件252、用于驱动调节件252沿鞘管23的轴向移动的驱动件254，以及两根牵引丝256，两根牵引丝256沿鞘管23的轴向可滑动地置于鞘管23的周壁内的不同位置，壳体21内设绕线部2115。优选的，绕线部2115邻近调节件252的近端处。两根牵引丝256的远端连接于可弯曲远端，其中一牵引丝256的近端连接于调节件252，另一牵引丝256的近端绕过绕线部2115连接于调节件252。具体的，其中一根牵引丝256的远端固定于鞘管23的固定段232，其中一牵引丝256的近端直接连接于调节件252；另一牵引丝256的远端固定于鞘管23的固定段232，另一牵引丝256的近端绕过绕线部2115后连接于调节件252。驱动件254可驱动调节件252移动并带动两根牵引丝256滑动，使鞘管23的可弯曲远端往不同方向弯曲，即鞘管23的弹性段235可往不同方向弯曲。
鞘管可调弯装置20包括鞘管23及调节机构25，鞘管23设置可弯曲远端且鞘管23的近端置于壳体21内；调节机构25包括调节件252、驱动件254，以及可滑动地置于鞘管23的周壁内的不同位置的两根牵引丝256，两根牵引丝256的远端分别连接于可弯曲远端，其中一根牵引丝256的近端直接连接于调节件252，另一根牵引丝256绕过绕线部2101后连接于调节件252。当驱动件254驱动调节件252沿主体段233的轴向朝远端或近端移动时，能带动两根牵引丝256滑动使鞘管23的可弯曲远端能朝不同的方向弯曲。由于鞘管可调弯装置20的鞘管23能朝不同的方向弯曲，因此，能减少鞘管23的转动次数，降低鞘管23的转动幅度；另外，鞘管可调弯装置20使用方便、操作简单，提高了鞘管可调弯装置20的工作效率，提升手术的成功率。

请一并参阅图8至图28，组装鞘管可调弯装置20时，先将调节件252螺接于驱动件254的转动筒2541内，并将一垫环255从近端套入转动筒2541，直至垫环255抵顶于操作部2543的近端面，垫环255方便驱动件254的转动；将鞘管23的主体段233的近端从转动筒2541的远端可滑动地穿过调节件252的通孔2520，将主体段233的近端卡固于定位管217的远端；将驱动件254的转动筒2541放置于第一外壳211的第一支撑片2113，定位管217的凸起2175卡接于两个第一定位片2116之间，凸起2175两端的定位管217卡入两个第一定位片2116的定位孔2118内。此时，驱动件254的操作部2543外露出第一外壳211的远端，垫环255的部分卡接于第一外壳211的限位槽2112内，鞘管23穿过两个第一定位柱2114之间的间隙及两个绕线部2115之间的间隙，定位管217的侧管2173穿插于第一延伸管2117内。
将其中一根牵引丝256的近端固定于调节件252的其中一固定孔2522的远端，另一根牵引丝256的近端绕过绕线部2115后固定于另一固定孔2522的远端。此时，两根牵引丝256位于鞘管23的轴心线相对的两侧，且两根牵引丝256处于拉紧状态，鞘管23的弹性段235呈伸直状态。
将套头2157套接于帽体2151的远端，将远端盖帽215的两个导滑柱2154的近端自转动筒2541的远端可滑动地穿过调节件252的两个导滑孔2524，直至导滑柱2154的近端分别卡接于两个第一定位柱2114的第一定位槽2110内。此时，鞘管23的远端分别穿过帽体2151及套头2157的通孔2152而外露；将第二外壳213盖合于第一外壳211，使垫环255的另一部分卡接于第二外壳213的限位槽2132内，且第二外壳213的卡接钩2139卡接于第一外壳211对应的卡接片2119，从而使调节机构25安装于第一外壳211与第二外壳213之间。此时，第二外壳213的第二支撑片2133与第一外壳211的第一支撑片2113一一对应，相对的第一支撑片2113与第二支撑片2132围成一个安装转动筒2541的圆形孔，驱动件254可在圆形孔内转动；第二外壳213的第二定位柱2134与第一外壳211的第一定位柱2114一一对应，相对应的第一定位柱2114的第一定位槽2110与第二定位柱2134的第二定位槽2130共同围成一个用于卡接鞘管23近端的空间；两个绕线部2115的末端抵接第二外壳213的内壁，能防止牵引丝256脱离绕线部2115；第二外壳213的第二定位片2136与第一外壳211的第一定位片2116一一对应，且对应的第一定位片2116的定位孔2118与第二定位片2136的定位孔2138围成安装定位管217的主管2171的空间。再将近端盖帽218的外螺纹2184螺接于主管2171的近端的内螺纹2176，且在近端盖帽218与主管2171之间设置密封圈219，密封圈219用于防止在介入手术过程中鞘管23内的血液或其他液体从近端盖帽21的近端流出。
驱动件254的操作部2543的沿周向的旋转运动用于转换为调节件252沿轴向的前后移动。具体地，操作部2543夹设在第一外壳211，第二外壳213与远端盖帽215之间，相对于壳体21在轴向上是固定的，即操作部2543无法沿轴向前后移动，操作部2543在周向上能够旋转。两个导滑柱2154固定在远端盖帽215中，从而相对于壳体21固定不同，两个导滑柱2154穿置于调节件252的两个导滑孔2524中，将调节件252的运动范围限定为相对于壳体21的轴向前后移动，调节件252在周向上固定。旋转操作部2543时，收容于驱动件254内的调节件252在周向上无法旋转，导致调节件252的外螺纹2526与驱动件254的内螺纹2545发生相对转动，调节件252与驱动件254在轴向上的位置发生相对变化，从而导致调节件252在轴向前后移动。
即在使用鞘管可调弯装置20时，通过操作操作部2543使驱动件254轴向转动，以带动调节件252沿导滑柱2154向近端或远端移动。调节机构25在初始状态下，当调节件252向近端移动时，能带动直接固定在调节件252的牵引丝256朝近端滑动，以使弹性段235朝向牵引丝256的一侧弯曲，弹性段235在弯曲的过程中，绕过绕线部2115后连接于调节件252的牵引丝256被弹性段235的变形而拉向远端滑动，以使弹性段235完成弯曲；调节机构25在初始状态下，当调节件252向远端移动时，绕过绕线部2115后连接于调节件252的牵引丝256被调节件252带动朝近端滑动，使弹性段235朝向牵引丝256的一侧弯曲，弹性段235在弯曲的过程中会带动直接固定在调节件252的牵引丝256朝远端滑动，以使弹性段235完成弯曲。
调节机构25的初始状态是指鞘管23的弹性段235处在伸直状态。
由于调节件252与驱动件254之间通过螺纹连接，当需要鞘管23的弹性段235弯曲时，只需操作操作部2543使驱动件254转动就能带动调节件252沿鞘管23轴向往复移动，以带动鞘管23的弹性段235弯曲至合适位置；当转动筒2541不转动时，就能定位调节件252。因此，本申请的鞘管可调弯装置20的鞘管23的弹性段235可弯曲至任意角度，并能在任意角度进行定位，鞘管可调弯装置20操作简单，使用方便，能提高工作效率，及提升手术的成功率。
在其他实施例中，调节机构25的驱动件254的转动筒2541可以用螺杆取代，调节件252轴向地设置与螺杆对应的螺纹通孔，螺杆螺接于所述螺纹通孔内，转动螺杆能带动调节件252轴向往复移动。具体的，螺杆设置于操作部2543径向横截面的中部，且沿轴向延伸，螺杆的中部轴向地开设通孔，螺纹通孔开设于调节件252径向横截面的中部并沿轴向穿通调节件252的近端面及远端面；螺杆螺接于螺纹通孔后，鞘管23的近端能滑动地穿过螺杆的通孔及螺纹通孔。导滑柱2154也可以从螺杆的通孔内滑动地穿过。

将推送件682的远端自第二转动件670的近端穿过通孔6701和推送管684内，使第二转动件670滑动至第一外壳611的远端，并将第一外壳611的两个第一支撑片6112分别插接于第二转动件670的两个导槽6706内；将第二外壳613连接于第一外壳611，第二外壳613的卡接钩6131分别卡接于第一外壳611的卡接片6118。此时，第二外壳613的两个第四支撑片6132分别插接于第二转动件670的两个导槽6706内、第五支撑片6133收容于转动柱664的导槽6642内、两个第六支撑片6135分别插接于第一转动件662的两个导槽6625内，以及两个导轨6136分别收容于第二夹持块655的两个滑槽6552内，弹性件658抵推第一夹持块654的卡齿6544卡接于齿条6117，第二转动件670的操作部6702外露出所述壳体61。再将外扣板615卡接于第二外壳613的安装口6138内，具体的，外扣板615的定位柱6151卡接于对应的定位块6137的卡孔内，卡钩6153卡接于对应的卡孔6139内，即安装完成。
使用推送装置时，按压按钮656使第一夹持块654朝向第二夹持块655移动，弹性件658发生弹性变形，直至活动块653被第一夹持块654与第二夹持块655夹紧定位，第一夹持块654的卡齿6544与齿条6117分离，沿第一外壳611的条形开口6116向近端或远端滑动按钮656，使活动块653随第一夹持块654与第二夹持块655向近端或远端滑动，以带动推送件682在推送管684内向近端或远端滑动，以实现推送件682的轴向滑动；当推送件682滑动至合适位置时，解除对按钮656的按压，弹性件658弹性复位而抵推第一夹持块654远离第二夹持块655，至第一夹持块654的卡齿6544卡接于齿条6117，定位滑动件650，以防止活动块653在轴向的滑动，从而对推送件682进行轴向定位。当需要转动推送件682时，解除对按钮656的按压，使第一夹持块654远离第二夹持件655，转动第一转动件662，带动导滑轨651、活动块653及转动柱664转动，即活动件653能在第一夹持块654的第一夹持槽6548与第二夹持块655的第二夹持槽6558围成的夹持槽内以推送件682的轴心线为转动轴转动，从而带动推送件682相对于推送管684转动。当需要转动推送管684时，转动第二转动件670的操作部6702使第二转动件670以推送件682的轴心线为转动轴转动，由于推送管684的近端固定于第二转动件670的通孔6701内，因此推送管684随第二转动件670转动。
推送装置60的滑动机构65能驱动推送件682沿轴向滑动，从而方便改变与推送件682的远端固定的封堵器在血管中的位置，并能控制所述封堵器的释放速度，当推送件682输送所述封堵器移动到合适位置后，松开按钮656，第一夹持块654在弹性件658的复位作用力下向第一外壳611运动，使卡齿6544与齿条6117卡合，以实现对推送件682和封堵器的定位，因此，滑动机构65可方便可靠地移动和定位封堵器。
在其他实施例中，第一支撑片6112及第四支撑片6132可以凸设于第二转动件670的转动部6704的外周面，环形的导槽6706可以开设于第一外壳611及第二外壳613的内壁；第二支撑片6113及第五支撑片6133可以凸设于转动柱664的外周面，导槽6642可以开设于第一外壳611及第二外壳613的内壁；第三支撑片6115及第六支撑片6135可以凸设于转动部6704的外周面，环形的导槽6706可以开设 于第一外壳611及第二外壳613的内壁。
封堵器紧锁系统在介入手术中，先确定好穿刺位置并穿刺完成后，将扩张器30的扩张杆32的远端自鞘管可调弯装置20的近端穿过近端盖帽218、密封圈219及定位管217插入鞘管23并露出于鞘管的远端，因扩张器30的远端为直径逐渐减小形成类圆锥状结构，在影像仪器的显影作用下，手术人员借助于扩张器30的远端结构能方便地将鞘管导入到病变位置附近，到达病变位置附近后，再撤出扩张器30，保留鞘管23在体内以建立由体外到体内的通道；将推送装置60的推送组件68的远端穿过装载器40的密封座44和装载管42，再将推送件682的远端和推送管684的远端相配合地同时与封堵器10可拆卸地固定，即凸出部152与推送管684螺接固定，且连接栓112与推送件682螺接固定，并改变推送件682与推送管684的相对位置以将封堵器10在轴向方向上拉伸使封堵器10易收入装载器40的装载管42内腔；将装载管42远端穿过盖帽218、密封圈219及定位管217插入鞘管23内，以得到装载封堵器10的输送系统；手握推送装置60的壳体61向远端推送推送组件68，将封堵器10送达鞘管可调弯装置20的鞘管23远端端口内，通过转动鞘管可调弯装置20和调弯鞘管23的弹性段235使鞘管23的弹性段235正对病变位置的裂口，缓慢地推动输送装置60的按钮656使可拆卸固定封堵器10的推送件682往裂口方向移动使封堵器10从鞘管23中露出，并将封堵器10释放到裂口的合适位置；滑动输送装置60的按钮656使推送件682沿轴向往近端方向慢慢移动，使封堵器10的第一封堵部11和第二封堵部15位于裂口的两端，在输送装置60的滑动机构65、第一转动机构66和第二转动机构670的作用下，完成封堵器10对裂口的封堵锁定和推送件682和推送管684与封堵器10脱离。
请一并参阅图1至图58，下面对第一实施例的封堵器紧锁系统的封堵器10的紧锁过程及推送件682和推送管684与封堵器10的脱离过程描述如下：
第一步：将螺母689卡合于延伸段6843的卡合槽6846内，推送件682的第三外螺纹6822与连接栓112的螺纹115螺纹固定，推送管684的第二内螺纹6842与凸出部152的第二外螺纹154固定。较佳的，凸出部152抵达于推送管684近端的外螺纹并与卡合槽6846相抵；
第二步：滑动按钮656沿轴向朝近端移动，带动推送件682沿轴向朝近端滑动使连接栓112的第一外螺纹113与螺母689抵顶连接；解除对按钮656的按压，弹性件658弹性复位而抵推第一夹持块654径向移动，至第一夹持块654的卡齿6544卡接于齿条6117，以固定连接栓112的位置；转动第二转动件670的操作部6702使第二转动件670轴向转动，带动推送管684转动使凸出部152往远端旋出。由于推送管684与凸出部152的螺纹紧固方向和连接栓112与螺母689的紧固方向相反，此时推送管684带动卡合槽6846内的螺母689一并转动使连接栓112往近端方向旋紧，连接栓112与螺母689紧固。当推送管684的第二内螺纹6842的齿距和齿牙与螺母689一致时，凸出部152旋出推送管684时，螺母689也完全套接于连接栓112；当推送管684的第二内螺纹6842的齿距和齿牙多于螺母689时，凸出部152旋出推送管684，螺母689也完全套接于连接栓112且连接栓112从螺母689的近端露出；
第三步：按压按钮656使卡齿6544与齿条6117分离，并滑动按钮656沿轴向向远端滑动，以带动推送件682沿轴向向远端滑动，将螺母689推出卡合槽6846并与凸出部152的近端面抵接。较佳的，在显影仪器的帮助下，观察连接栓112是否从螺母689的近端露出，如果没有，将滑动推送件682在轴向方向向近端滑动并带动螺母689抵接推送管684并落入卡合槽6846中，反向转动推送管684使推送管684和凸出部152紧固处理，同时使连接栓112与螺母689分离处理，并进行第二步操作直到在显影仪器下观察连接栓112的近端露出于螺母689；如果观察到连接栓112从螺母689的近端露出，至此完成成了封堵器10的完全锁紧，并且可以确定螺母689的螺纹已经完全旋进连接栓112使连接栓112和螺母689固定良好，可避免螺母689的部分螺纹旋进连接栓112使连接栓112和螺母689固定不良而发生螺母689脱落的风险。再转动第一转动件662带动推送件682转动使推送件682与连接栓112分离，这样，就完成了封堵器10的脱离。
从上述三步骤可知，推送管684与封堵器10的凸出部152螺纹连接，连接栓112设置了内外螺纹且连接栓112与推送件682螺纹固定，封堵器10的紧锁只需往近端方向轴向滑动推送件682，让连接栓112的第一外螺纹113与卡合于推送管684的卡合槽6846的螺母689的内螺纹相抵接，再转动推送管684带动螺母689旋进连接栓112就可完成封堵器10的紧锁。由于推送管684与凸出部152的螺纹紧固方向和连接栓112与螺母689的紧固方向相反，且延伸段6843和凸出部152的螺牙和螺距等于或多于螺母689的螺牙和螺距，在螺母689旋进连接栓112的同时，封堵器10的凸出部152旋出推送管684，以实现凸出部152与推送管684的分离；最后再转动推送件682使之与连接栓112分离，即可实现封堵器10与推送组件68的分离。通过显影仪器观察能确认连接栓112的近端是否露出于螺母689，可以多次操作推送组件68和封堵器10重新进行锁紧处理直到连接栓112的近端露出于螺母689，从而确保封堵器10锁紧完全。由此可知，该封堵器紧锁系统具有操作简便、分离和紧固可靠性高等优点。
请参阅图59，本申请的第二实施例提供的封堵器紧锁系统的结构与第一实施例的结构相似，不同之处在于：第二实施例的推送装置的推送管684a的结构与第一实施例中的推送管684的结构略有不同。在第二实施例中，推送管684a的延伸段6843的内壁在第二内螺纹6842与卡合槽6846之间设置空转槽6847，凸出部152连接至推送管684内时，凸出部152的第二外螺纹154能在空转槽6847内转动。具体的，延伸段6843的第二内螺纹6842向近端方向并没有延伸至卡合槽6846，即延伸段6843的内壁邻近卡合槽6846的一端没有设置内螺纹。空转槽6847的内径与凸出部152的外径一致，空转槽6847的轴向长度不小于凸出部152的第二外螺纹154的轴向延伸长度。
请一并参阅图60至图64，下面对第二实施例的封堵器紧锁系统的封堵器10的紧锁过程及推送件682和推送管684a与封堵器10的脱离过程描述如下：
第一步：将螺母689卡合于延伸段6843的卡合槽6846内，推送件682的第三外螺纹6822与连接栓112的螺纹115螺纹固定，凸出部152的第二外螺纹154与推送管684a的第二内螺纹6842螺接并转动推送管684a带动凸出部152进入推送管684的空转槽6847内。较佳的，凸出部152抵达于推送管684a近端的外螺纹与卡合槽6846相抵；
第二步：滑动按钮656沿轴向朝近端移动，带动推送件682沿轴向朝近端滑动使连接栓112的第一外螺纹113与螺母689的内螺纹抵顶连接；解除对按钮656的按压，弹性件658弹性复位而抵推第一夹持块654径向移动，至第一夹持块654的卡齿6544卡接于齿条6117，以固定连接栓112的位置；通过不停地转动第二转动件670的操作部6702使第二转动件670轴向转动，带动推送管684a不停地转动。凸出部152在空转槽6847内空转，可以调整连接栓112与螺母689的相对位置，使连接栓112的第一外螺纹113与螺母689的内螺纹抵顶完全，以便于连接栓112顺利地螺入螺母689内。此时，推送管684a带动卡合槽6846内的螺母689一并转动使连接栓112往近端方向旋紧，连接栓112与螺母689紧固。
第三步：滑动推送件682沿轴向向远端滑动，将螺母689推出卡合槽6846并与凸出部152的近端面抵接。在显影仪器的帮助下，观察连接栓112是否从螺母689的近端露出，如果没有，将滑动推送件682在轴向方向往近端滑动并带动螺母689抵接推送管684，反向转动推送管684a使推送管684a和凸出部152紧固处理，同时使连接栓112与螺母689分离处理，并进行第二步直到在显影仪器下观察连接栓112的近端露出于螺母689；如果观察到连接栓112从螺母689的近端露出，至此完成成了封堵器10的完全锁紧，并且可以确定螺母689的螺纹已经完全旋进连接栓112使连接栓112和螺母689固定良好，可避免螺母689的部分螺纹旋进连接栓112使连接栓112和螺母689固定不良而发生螺母689脱落的风险。再转动第一转动件662带动推送件682转动使推送件682与连接栓112分离，这样，就完成了封堵器10的脱离。
从上述第二实施例的封堵器紧锁系统的封堵器10的紧锁过程及推送件682和推送管684a与封堵器10的脱离过程可知，因推送管684a的延伸段6843内壁在第二内螺纹6842与卡合槽6846之间设置空转槽6847，在调整连接栓112与螺母689相抵接的相对位置过程中，凸出部152在空转槽内空转，而非像第一实施例中的封堵器紧锁系统中，此时的凸出部152正在延伸段6843的第二内螺纹6842内转动而旋出推送管684。因连接栓112、凸出部152、螺母689和延伸段6843的卡合槽6842的尺寸很小，通常在几毫米之间，在现有常用的大部分制备技术下制备出的连接栓112、螺母689和卡合槽6864过程中存在一些不可避免的尺寸误差。当滑动推送件682沿轴向向近端滑动使连接栓112的第一外螺纹113与螺母689抵顶连接，此时，连接栓112与螺母689相抵接的相对位置可能是连接栓112恰好能旋进螺母689，也可能是连接栓112与螺母689的螺纹不完全抵接，需要调整连接栓112与螺母689的相对位置才能使连接栓112的第一外螺纹113与螺母689的内螺纹的位置完全抵顶，达到螺母689能旋进第一外螺纹113的位置。因此，延伸段6843设置的空转槽6847，使在调整连接栓112与螺母689的相对位置过程中，推送管684a与凸出部152之间的相互作用几乎可以忽略不计，远小于第一实施例中的封堵器紧锁系统中在调整连接栓112与螺母689的相对位置过程中，推送管684与凸出部152之间螺纹转动连接受到的螺纹转动摩擦力，一方面，方便调整连接栓112与螺母689的相对位置以达到螺母689能旋进连接栓112的位置；另一方面，第一实施例中的封堵器紧锁系统的延伸段6843内设的抵接于卡合槽6846的内螺纹，在凸出部152旋出延伸段6843的过程中，也可实现调整连接栓112与螺母689的相对位置的功能，但这要求把凸出部152的长度做的较长，使凸出部152在延伸段6843内能较长时间的螺纹转动来调整连接栓112与螺母689的相对位置，但较长的凸出部152在介入手术完成后会留在破口位置，会影响外周血管或心脏等内部的血液流动，增大术后并发症的风险。在第二实施例中的封堵器紧锁系中，因延伸段6843内设置空转槽6847，在调整连接栓112与螺母689的相对位置以使得螺母689能旋进连接栓112的过程中，凸出部152与延伸段6843的相对位置不发生变化，这可以大大缩短凸出部152的长度，从而减少手术完成后封堵器10露出于破口位置的血管壁或心脏壁等的距离，大大降低术后并发 症的风险。
请参阅图65及图66，本申请的第三实施例提供的封堵器紧锁系统的结构与第一实施例的结构相似，不同之处在于：第三实施例的延伸段6843近端的内壁的卡合槽6846内壁开设第三内螺纹6848，螺母689a是圆柱形螺母，螺母689a的侧壁设置第四外螺纹，螺母689a的第四外螺纹可螺接于第三内螺纹6848，螺母689a的第四外螺纹和第三内螺纹6848的紧固方向与第二内螺纹6842和第二外螺纹154的螺纹紧固方向相同，螺母689a的第四外螺纹和第三内螺纹6848的紧固方向与连接栓112和螺母689a的内螺纹紧固方向相反。具体的，延伸段6843近端的卡合槽6846为圆形孔，即卡合槽6846的径向横截面为圆形，卡合槽6846的内壁设置第三内螺纹6848。螺母689a为圆柱形的螺母，螺母689a的外径与卡合槽6846的内径一致，螺母689a的侧壁设置与第三内螺纹6848匹配的第四外螺纹。卡合槽6846内壁的第三内螺纹6848和螺母689a的第四外螺纹的紧固方向与延伸段6843的第二内螺纹6842与凸出部152的第二外螺纹154的紧固方向相同；卡合槽6846内壁的第三内螺纹6848和螺母689a的外螺纹的紧固方向与连接栓112的第一外螺纹113和螺母689a的内螺纹紧固方向相反。优选的，卡合槽6846内壁的第二内螺纹6842、螺母689a的内外螺纹及连接栓112的第一外螺纹113的齿距、齿牙以及螺纹的整体长度大小一致；在转动推送管684能使螺母689a旋进连接栓112完成螺母689a和连接栓112的螺纹连接过程中，同时可实现凸出部152与延伸段6843的分离以及螺母689a与卡合槽6846的分离；另外，因卡合槽6846和螺母689a间是螺纹连接，而不是像六角螺母等与卡合槽6846是通过规则的形状实现卡合，使螺母689与卡合槽6846之间存在尺寸误差，能大大减少滑动推送件682沿轴向向近端滑动使连接栓112的第一外螺纹113与圆柱形的螺母689a的内螺纹抵顶连接需要再次调整连接栓112和螺母689a相对位置的风险，即提高滑动推送件682沿轴向向近端滑动使连接栓112的第一外螺纹113与圆柱形的螺母689a的内螺纹抵顶连接的可靠性，避免调整连接栓112和螺母689a相对位置的步骤，可减少凸出部152的长度，简便了操作步骤。
第三实施例的封堵器紧锁系统的封堵器10的紧锁过程及推送件682和推送管684与封堵器10的脱离过程与第一实施例相似。

紧锁处理包括：
S21滑动推送件682将第一封堵部11靠近第二封堵部15，第一封堵部11和第二封堵部15都紧贴破口，此时，连接栓112已抵接螺母689；

以上是本申请实施例的实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请实施例原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
