扳机结构，通过滑动扳机，使扳机上不同的第一锁止部与第一卡合部配合，以带动小车间歇式地滑动，从而使小车的第二卡合部与不同的第二锁止部配合，实现小车锁止在手柄的不同位置，全程只需要不断地操作扳机，就可以实现小车沿滑动方向固定于手柄的不同位置，操作简单，提高操作效率。

现有的通道器械存在操作效率不高的问题。发明人研究发现，现有用于形成手术通道的金属网释放不够快捷，进一步研究发现，用于压缩金属网的方式较复杂，导致金属网无法快速释放，影响了操作效率。本实施例提供的手术用通道器械及扳机结构能够改善上述 问题。
下面结合图1至图8对本实施例提供的手术用通道装置进行详细描述。
请参照图1，本实施例提供了一种手术用通道装置10，包括：牵开器，牵开器包括配置成形成手术通道111的金属网100；输送器110，输送器110的远端具有配置成放置金属网100且可打开的通道111；捆绑绳120和捆绑丝130，捆绑绳120配置成绕在金属网100上，捆绑丝130配置成穿过捆绑绳120，并收紧捆绑绳120，以压缩金属网100；或捆绑丝130配置成脱离捆绑绳120，以松开捆绑绳120和金属网100。
需要说明的是：本领域技术人员可以理解，全文中，手术用通道装置10在使用过程中，输送器110的前端配置成伸入脑组织内，将牵开器的前端送入脑组织内，输送器110的后端由医生操作。因此，相对地，每个零部件靠近输送器110前端的部分成为该零部件的远端，该零部件靠近输送器110后端的部分称为该零部件的近端。其中，输送器110的前端即为输送器110的远端，输送器110的后端即为输送器110的后端。
继续参照图1，牵开器包括金属网100，金属网100由记忆合金材料编织而成。牵开器可以被压缩至很小直径后送入脑组织中，释放后将在其自身弹性和记忆性能下恢复到原先设计的形状，以撑开脑组织，形成供显微镜/内窥镜治疗所需要的手术通道111，极大的提高了显微镜/内窥镜手术实用范围，减少脑组织创伤。牵开器压缩至很小直径插入脑组织中，减少切开脑组织的过程。本实施例中，恢复原状的牵开器呈中空的圆柱状。牵开器还包括覆盖在金属网100外表面的透明膜层，配置成提高金属网100外表面的光滑度，以减少对脑组织的创伤。
继续参照图1，输送器110配置成将压缩成很小直径的牵开器插送到脑组织中。通道111可打开，金属网100放置于通道111内，在通道111打开后，金属网100完全露出后释放，形成手术通道111。本实施例中，金属网100在通道111中处于压缩状态，在通道111打开后，金属网100释放后恢复原状。
请继续参照图1，本实施例中，捆绑绳120可以绕在金属网100上，通过拉紧捆绑绳120，可以将金属网100收紧。捆绑丝130通过穿过捆绑绳120的方式将捆绑绳120拉紧在捆绑丝130上。本实施例中，通过捆绑绳120连接金属网100上的多个点和捆绑丝130上的一个点，多个点连接收紧到一个点，即可以实现金属网100的压缩。
具体地，参照图3，捆绑绳120配置成依次穿过金属网100的远端的多个网孔101，以与金属网100之间形成沿金属网100周向分布的多个环孔121。具体地，金属网100的远端具有多个沿周向依次分布的网孔101，捆绑绳120的一端从其中一个网孔101穿入，从相邻的网孔101穿出，相邻的两个网孔101，捆绑绳120的穿设方向相反，从而穿过相邻的两个网孔101之间的捆绑绳120形成一个环孔121。其中，本实施例中，捆绑绳120的两端首尾连接。在其他实施例中，捆绑绳120的两端可以连接在金属网100上。
其中，捆绑绳120可以采用尼龙绳或者其他的柔性线绳。
继续参照图3，捆绑丝130配置成依次穿过多个环孔121，并在拉直状态时收紧捆绑绳120。捆绑丝130的远端沿周向依次穿过多个环孔121之后，拉直捆绑丝130，则从相邻的 两个网孔101穿出的捆绑绳120均套在捆绑丝130上，并收拢在一起，从而实现金属网100的压缩。
利用捆绑绳120的柔性特征，可以将金属网100收紧在呈拉直状态的捆绑丝130上，捆绑绳120易绕在金属网100上，装配简单。捆绑丝130抽离捆绑绳120可以实现捆绑绳120和金属网100的松开，操作简单。
请再次参照图1，结合图2，本实施例中，输送器110包括穿刺头140，穿刺头140上设置与通道111连通的第一孔141；捆绑丝130呈拉直状态时，捆绑丝130的远端容置于第一孔141内，捆绑丝130的近端向远离第一孔141的方向延伸，以配置成在外力的作用下发生移动，从而拉动捆绑丝130脱离捆绑绳120。
穿刺头140配置成在手术时穿刺脑组织。以图1中的相对位置进行介绍，穿刺头140设置在输送器110的最左端，从左到右依次设置穿刺头140和通道111，第一孔141的右端与通道111连通。捆绑丝130的远端穿过捆绑绳120后伸入第一孔141内。第一孔141对捆绑丝130具有支撑和限位的作用，防止捆绑丝130任意移动，保持捆绑绳120收紧在捆绑丝130上，从而保持金属网100的压缩状态，同时对金属网100位置具有限位作用，防止金属网100朝通道111的近端移动。本实施例中，第一孔141设置在穿刺头140的侧部，第一孔141的位置根据捆绑丝130处于拉直状态后在远端的位置来设计。第一孔141的左端贯穿穿刺头140，或者第一孔141的左端封闭。
继续参照图2，本实施例中，输送器110还包括固定块150，固定块150固定在通道111内，且设置限位孔151；捆绑丝130配置成活动穿过限位孔151，并借助于固定块150被限位。具体地，限位孔151的两端贯穿。固定块150与穿刺头140之间具有间隙，金属网100的远端位于该间隙内，捆绑丝130的远端穿过限位孔151后，再穿过捆绑绳120，拉直后伸入第一孔141内。限位孔151对捆绑丝130具有限位的作用，以使捆绑丝130更易保持拉直的状态，减少其他部件对捆绑丝130拉直状态的影响。
继续参照图2，本实施例中，固定块150设置在通道111的远端，且位于金属网100内侧，以配置成阻止金属网100朝通道111的近端移动。金属网100套在固定块150的外周，金属网100的远端被压缩后，金属网100受到固定块150的阻碍，无法向通道111的近端移动，金属网100进一步被限制在通道111的远端。
继续参照图2，本实施例中，穿刺头140设置连通通道111和外部的注射孔142；输送器110还包括支撑管160和鲁尔接头161，支撑管160设置在通道111内，支撑管160的远端与穿刺头140连接且与注射孔142连通；鲁尔接头161与支撑管160的近端连通，以配置成注入液体。进一步地，鲁尔接头161与支撑管160的近端连通。
鲁尔接头161(Luer taper)是一种标准化的微量无渗接头，通过公鲁尔接头161与相匹配的母鲁尔接头161部分来连接。鲁尔接头161配置成注入液体，液体进入支撑管160后从注射孔142射出，或者配置成手术用通道装置10插入脑组织过程中冲洗或者吸取脑积液。
具体地，参照图1，穿刺头140的端部呈椭圆形。有助于在插入过程中推挤开血管，不会造成血管的切断。牵开器撑开脑组织的过程是柔性的圆周方向撑开，圆周方向受力， 受力面积比两个脑压板向两侧扒开要大，不会造成使用脑压板常造成的脑组织局部过度受压。
其中，注射孔142设置在穿刺头140的中部，注射孔142的两端分别贯穿穿刺头140的两端。具体地，支撑管160的远端插设在穿刺头140上，且与注射孔142连通。
其中，参照图1，固定块150固定在支撑管160上。具体地，结合图4，固定块150设置有装配孔152，限位孔151和装配孔152间隔设置，支撑管160穿过装配孔152且固定。
继续参照图2，本实施例中，手术用通道111器械还包括外管180，外管180可滑动地套在支撑管160的外侧，外管180内壁和支撑管160外壁之间形成通道111。圆周的管状通道111，视野暴露清晰，对手术操作的难度及掌控度均有大幅度改善，使此手术便捷易于推广，并可和立体定向或计算机导航结合对手术区域达到精准定位的效果。
具体地，外管180的远端与穿刺头140接触，以密封通道111。金属网100套在支撑管160和外管180之间，金属网100的远端压缩后收紧在支撑管160上。外管180相对支撑管160滑动时，通道111被打开，金属网100露出，金属网100在弹性恢复力的作用下释放后展开，抽走捆绑丝130后，金属网100的远端也释放展开。
再次参照图1，本实施例中，输送器110还包括卡环170，卡环170与捆绑丝130连接，以配置成在外力作用下拉动捆绑丝130脱离捆绑绳120。通道111打开后，外力拉动卡环170，将捆绑丝130抽离捆绑绳120，使金属网100释放。继续参照图1，本实施例中，输送器110还包括卡接部，卡环170配置成与卡接部卡接或脱离；卡环170与卡接部脱离时，卡环170配置成在外力作用下拉动捆绑丝130脱离捆绑绳120。卡环170通过卡接在卡接部上实现固定，在通道111打开后，将卡环170拆卸下来，然后拉动卡环170和捆绑丝130。继续参照图1，本实施例中，卡接部呈柱状；卡环170包括相互连接的半圆环171和拨动手柄172，半圆环171配置成与卡接部的外壁卡接或脱离。半圆环171与卡接部的卡接和脱离，通过拨动手柄172实现。具体地，拨动手柄172采用圆环状。
继续参照图1，本实施例中，鲁尔接头161部分形成卡接部，半圆环171配置成与鲁尔接头161的外壁卡接或脱离。卡环170与鲁尔接头161脱离时，卡环170配置成在外力的作用下移动，以拉动捆绑丝130脱离捆绑绳120。
具体地，捆绑丝130的近端与卡环170连接。
卡环170包括沿鲁尔接头161轴向延伸的第一连接段，第一连接段的一端与捆绑丝130连接，第一连接段的另一端与半圆环171的一端连接，半圆环171沿鲁尔接头161的周向延伸。卡环170还包括第二连接段，半圆环171和拨动手柄172之间通过第二连接段连接，其中，第二连接段与半圆环171位于同一平面内，且第二连接段沿半圆环171的直径方向设置。第二连接段和第一连接段垂直。
装配时，第一连接段远离半圆环171的一端与捆绑丝130连接，半圆环171卡在鲁尔接头161上。在需抽离捆绑丝130时，握住拨动手柄172，带动半圆环171转动，使半圆环171从鲁尔接头161上脱落，从而可以握住卡环170向外拉动捆绑丝130，从而将捆绑丝130拉出捆绑绳120，实现捆绑绳120的释放。
请参照图5至图8，本申请的实施例还提供了一种扳机结构20，包括小车210、扳机220和手柄230；扳机220和小车210共同可滑动地设置在手柄230上；小车210设置第一卡合部211和第二卡合部212；扳机220设置第一锁止部221，第一锁止部221的数量为多个；手柄230设置第二锁止部231，第二锁止部231的数量为多个；不同的第一锁止部221配置成与第一卡合部211配合，以带动小车210相对手柄230间歇性地滑动，以使第二卡合部212与不同的第二锁止部231配合，从而将滑动中的小车210锁止在手柄230的不同位置。
通过滑动扳机220，使扳机220上不同的第一锁止部221与第一卡合部211配合，以带动小车210间歇式地滑动，从而使小车210的第二卡合部212与不同的第二锁止部231配合，实现小车210锁止在手柄230的不同位置，全程只需要不断地操作扳机220，就可以实现小车210沿滑动方向固定于手柄230的不同位置，操作简单，提高操作效率。
继续参照图5，第一锁止部221配置成扳机220沿第一方向相对手柄230滑动时，与第一卡合部211锁止配合，以使扳机220推动小车210沿第一方向滑动；第一锁止部221配置成扳机220沿第二方向相对手柄230滑动时，与第一卡合部211滑动配合，在第一锁止部221与第一卡合部211滑动配合时，小车210相对手柄230固定；其中，第一方向与第二方向相反。
需要说明的：“第一方向”为图1中箭头A所指的方向，“第二方向”为图1中箭头B所指的方向。
具体地，扳机220沿第一方向移动，此时第一锁止部221能够与第一卡合部211锁止配合，扳机220沿第一方向移动的过程中带动小车210沿第一方向同步移动。在小车210沿第一方向移动的过程中，第二卡合部212能够不断地与不同的第二锁止部231配合，以将小车210锁止在不同的位置。扳机220沿第二方向移动时，第一锁止部221与第一卡合部211滑动配合，扳机220沿第二方向的移动不会影响小车210的移动，小车210依旧锁止在手柄230上。因此，扳机220不断地沿第一方向和第二方向往复移动，可以不断地推动小车210沿第一方向不断移动。
再次参照图5，本实施例中，扳机结构20还包括复位件；复位件连接在扳机220和手柄230之间，以使扳机220具有沿第二方向相对手柄230滑动的趋势。具体地，复位件采用弹簧250，弹簧250的一端与手柄230连接，弹簧250的另一端与扳机220连接。
外力驱动扳机220沿第一方向移动，从而带动小车210沿第一方向移动，并在外力撤走后，不干涉小车210相对手柄230的固定。外力撤走后，扳机220在复位件的作用下沿第二方向移动，扳机220复位，此时再施加外力，推动扳机220沿第一方向移动，进而带动小车210沿第一方向再移动一段距离，这样反复推动扳机220和撤去外力，使扳机220沿第一方向和第二方向往复移动的过程中，推动小车210不断沿第二方向移动。
请再次参照图5，结合图6，第一锁止部221为凸设在扳机220上的第一单向齿；第二锁止部231也为凸设在手柄230上的第二单向齿。
扳机220的第一单向齿沿第一方向移动时，与第一卡合部211锁止，以带动第一卡合 部211移动。第一单向齿沿第二方向移动时，与第一卡合部211滑动配合，与第一卡合部211互不干扰。
小车210的第二卡合部212沿第一方向移动时，与第二单向齿滑动配合，因此小车210能够不断沿第一方向移动。小车210的第二卡合部212不能沿第二方向移动，锁止在第二单向齿上。
请参照图7，本实施例中，第一卡合部211为第一弹片，第一弹片的一端连接在小车210上，第一弹片的另一端配置成沿第一方向移动时与第一单向齿锁止配合，沿第二方向移动时与第一单向齿滑动配合。
请参照图8，本实施例中，第二卡合部212为第二弹片，第二弹片的一端连接在小车210上，第二弹片的另一端配置成沿第一方向移动时与第二单向齿锁止配合，沿第二方向移动时与第二单向齿滑动配合。
具体地，结合图5，以图5中的相对位置进行介绍，小车210和扳机220均设置在手柄230上，小车210设置在扳机220的上方。第一弹片设置在小车210的底部，其中，第一弹片的近端连接在小车210的底部，第一弹片的远端与小车210底部之间呈夹角设置；第一单向齿沿第一方向设置，且设置在扳机220的顶部，第一单向齿为斜面齿，朝向右上方倾斜。第一弹片的远端与第一单向齿配合，第一弹片相对第一单向齿可沿第一方向滑动，在第二方向上，第一弹片与第一单向齿锁止，不能沿第二方向移动。
进一步地，第二弹片设置在小车210的侧部，第二弹片的近端连接在小车210的侧部，第二弹片的远端与小车210侧部之间呈夹角设置；第二单向齿沿第一方向设置在手柄230内，且对应小车210的侧部，第二单向齿也为斜面齿，朝向右上方倾斜、。第二弹片的远端与第二单向齿配合，第二弹片相对第二单向齿可沿第一方向滑动，在第二方向上，第二弹片与第二单向齿锁止，不能沿第二方向移动。
请再次参照图1和图5，输送器110还包括锁扣260；手柄230上设置滑道，小车210可滑动地设置在滑道上，手柄230上设置有两个插孔，滑道穿过两个插孔之间；小车210上设置有限位把手。锁扣260与两个插孔可拆卸地卡接，在锁扣260与两个插孔卡接时，锁扣260能够抵住限位把手，防止小车210朝输送器110的远端移动，在锁扣260与插孔脱离时，小车210可沿输送器110的远端移动。因此，在操作扳机220驱动小车210沿第一方向移动之前，需将锁扣260从插孔下拔出。锁扣260主要为了防止误操作。
具体地，锁扣260包括第一锁条和第二锁条，第一锁条与第二锁条垂直设置，第二锁条的一端连接在第一锁条的中部，第二锁条配置成与插孔配合。实际操作时，操作者握住第一锁条即可实现第二锁条插入或者脱离插孔。
需要说明的是，本文中的“垂直”，并不要求两者的夹角一定是90°，而是可以稍微倾斜，例如夹角的范围在88°-90°之内，依然可以认为两者是垂直的。示例：第一锁条与第二锁条之间的夹角也可以为88°、89°等。
另外，手术用通道装置10中，小车210与外管180连接，在小车210相对手柄230滑动的过程中带动外管180移动，打开通道111。具体地，外管180的近端与小车210连接。 进一步地，外管180的近端设置有内螺纹段，小车210设置有外螺纹段，内螺纹段和外螺纹段螺纹连接。通过驱动扳机220移动，扳机220不断驱动小车210沿第一方向移动，带动外管180沿第一方向移动，打开通道111，将金属网100释放，形成手术通道111。
本实施例中，由于牵开器比较软，对于手术过程中，通道111是需要进行方向调整的，无法直接扳动牵开器的方向。本实施例中，通过牵开装置300对手术通道111方向进行调整，也就是对金属网100建立的手术通道111进行调整，具体通过对牵开器的方向调整实现。具体地，将牵开装置300插入金属网100中进行方向的调整。
请参照图9和图10，本实施例提供的牵开装置300，包括管状外套310和一端具有圆头的内芯320；外套310和内芯320活动套设且可拆卸地连接，内芯320的圆头突出外套310，外套310还设置配置成与外部设备连接的连接结构。其中，外套310和内芯320通过卡扣330进行锁定。实际使用时，内芯320套在外套310内，并通过卡扣330固定连接，外套310和内芯320一起插入金属网100的过程中，内芯320的圆头配置成与脑组织接触，避免造成脑组织的创伤，然后取出内芯320，外套310可以根据需要调整的方向进行转动，方向调整到位后，外套310通过连接结构与外部设备固定连接，完成对金属网100形成的手术通道111的调节。
进一步地，外套310和内芯320使用PC或类似的透明硬质材料制成，透明材料方便观察周围脑组织情况。
根据本实施例提供的一种手术用通道装置10，手术用通道装置10的使用过程如下：
第一步：移除锁扣260；
第二步：扳动扳机220，此时外管180向输送器110的近端退回，多次扳动扳机220，直到牵开器完全露出外管180，此时牵开器的近端张开，牵开器的远端由于捆绑线绳和捆绑丝130的捆绑，固定在穿刺头140和固定块150之间。
第三步：旋转卡环170，使它与鲁尔接头161脱离，再往后回撤卡环170，将捆绑丝130从穿刺头140、捆绑绳120和固定块150抽出，牵开器的远端被释放，此时牵开器与支撑管160无连接，移开输送器110，牵开器在自身弹性作用下恢复圆筒状，与支撑管160分离，此时取走输送器110，牵开器将形成手术需要的通道111。
根据本实施例提供的一种手术用通道装置10，手术用通道装置10进行手术的方法步骤如下(以脑出血为例)：
1.脑出血的病人，备皮后，头上贴上标记(mark)，行头颅CT或MRI检查；
2.将检查数据输入计算机工作站；
3.确认头皮切开部位；
4.全麻后，常规消毒铺巾；
5.切开头皮，可采用直切口；
6.磨钻形成直径3cm的游离骨瓣；
7.切开硬脑膜；
8.在皮层无血管区，在导航的导航棒引导下，插入本产品的穿刺头140及其所连接的外管180的前端位置，精确进入血肿腔后；取出锁扣260，扣动扳机220，使外管180慢慢脱离牵开器；初始，牵开器前端的捆绑绳120通过捆绑丝130固定在穿刺头140上。在外管180慢慢脱离牵开器的过程中，牵开器后部缓慢扩展形成后端通道111；待牵开器完全释放后(即与外管180完全分离)，转动手柄230后端卡环170，使得它与鲁尔接头161松开；回撤卡环170，使牵开器前端的捆绑丝130与金属网100分离，此时牵开器远端慢慢展开，直至整个牵开器全部释放完毕。取出输送器110，形成手术腔道。通过此腔道实施显微镜/内窥镜下清除血肿，止血满意后，轻捏牵开器(金属网100的远端在输送器110的输送下进入脑组织，金属网100的近端位于脑组织外，此时，轻捏的是金属网100的近端)，收缩后即可拔出，穿刺道内显微镜/内镜下贴敷速即纱；
9.严密缝合硬脑膜；
10.骨瓣复位钛条固定；
11.缝合头皮各层。
本实施例提供的一种手术用通道装置10至少具有以下优点：
采用捆绑绳120和捆绑丝130实现金属网100的压缩，结构简单可靠，装配简单；操作时只需要将捆绑丝130抽离捆绑绳120，即可实现金属网100的释放，操作简单，提高了手术效率，降低了手术风险。
采用扳机结构20实现通道111的开启，重复操作扳机220即可实现外管的后撤，操作快捷；同时扳机220只需要单手操作，进一步简化操作，提高操作效率。
锁扣260插在手柄230上时，扳机220和小车210无法移动，正常操作时，需要先将锁扣260移除，才可以扳动扳机220实现外管180的后撤，锁扣260具有防止误操作扳机220，造成外管180后撤，金属网100意外释放的作用。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
