Description

腔镜外科手术用缝切装置 技术领域
本发明属于医疗器械领域，涉及一种手术用器械，特别涉及一种具有可摆动头部的腔镜外科手术用缝切装置。
背景技术
外科手术用缝切装置已被广泛用于伤口的缝合、内部组织的缝合与切割，目前也已经开发了适用于腔镜外科手术的缝切装置。腔镜外科，也称腹腔镜外科，是以电子镜像代替肉眼直视、以细长器械代替手指，力求在最小的切口路径、最少的组织损伤、肌体最轻的应激反应下，完成对体内病灶的观察、诊断、切割、缝合及其他治疗。
腔镜外科手术用缝切装置，一般包括器械平台和可拆卸地安装于该平台上的头部，器械平台包括击发把手，可拆卸的头部包括一本体和安装于该本体的远端的钉头部，本体包括壳体和设于壳体内的击发组件；钉头部为实施切割和缝合动作的部分，其包括钉仓组件、钉砧组件以及切刀组件，该缝切装置的头部可以通过穿刺器穿过身体上的小切口以接近手术部位实施手术。击发组件在击发把手的驱动下，推动钉仓组件和切刀组件以完成缝切手术。通常，钉头部通过一铰接机构安装于本体的远端，该铰接机构使得操作者可以远距离地操作钉头部相对于本体作顺时针或逆时针摆动。
目前现有的腔镜外科手术用缝切装置中，钉头部相对于主体向任意一侧摆动的最大角度为45度左右，在具体的手术实践中，经常不能满足外科医生的使用要求。因此，目前亟需一种钉头部摆动角度更大的腔镜外科手术用缝切装置。

具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
本发明内所描述的表达位置与方向的词，均是以器械操作者作为参照，靠近操作者的一端为近端，远离操作者的一端为远端。轴向是指远端到近端的长度方向。
本实施方式中所提到的“第一”、“第二”等并不包含位置关系或结构功能上的绝对区分关系，并且，在不同的实施方式中，可能使用相同的标记或者标号，这也并不代表结构或者功能上的联系，而仅仅是为了描述的方便。
参见图1至图7，介绍本发明腔镜外科手术用缝切装置的一具体实施方式。
参见图1至图3，该装置包括：本体1、钉头部2以及传动机构3，钉头部2通过传动机构3相对于本体1的轴向可摆动地连接于本体1的远端。
在本实施方式中，本体1可以包括壳体11和设置在壳体11内的击发组件等(图中未示出)。
在本实施方式中，钉头部2为实施切割、缝合动作的部分，钉头部2可以包括钉仓组 件、钉砧组件以及切刀组件等，图中仅标识了沿钉头部2的轴向延伸设置的钉仓架21。
传动机构3包括：操作杆31、齿轮传动组件32以及联接组件33。
联接组件33至少包括第一转接件332。第一转接件332的近端与本体1相转动地连接，第一转接件332的远端与钉头部2相转动地连接。
操作杆31具有作动端312和连动端311。操作杆31的连动端311与第一转接件332连接。在本实施方式中，操作杆31通过第一铰接部A与第一转接件332铰接。具体的，在本实施方式中，第一转接件332上固设有圆柱销作为第一铰接部A，连动端311上开设有与圆柱销配合的销槽。在本发明的替代实施方案中，可以在连动端311上固设圆柱销作为第一铰接部A，第一转接件332上开设与圆柱销配合的销槽；也可以采用其他枢轴连接/铰接的方式。
在本实施方式中，连动端311可滑动地设置在本体1内。在本实施方式中，连动端311大致沿壳体11向远端或近端滑动。
在本实施方式中，联接组件33还包括第一联接件331和第二联接件333。第一联接件331与本体1固定连接。第一转接件332的近端通过第二铰接部B与第一联接件331的远端铰接。第一转接件332的远端与第二联接件333的近端固定连接。第二联接件333的远端通过第三铰接部C与钉头部2铰接。
在本实施方式中，第一转接件332与第二联接件333通过固定轴S固定连接，其中固定轴S可以是固定设置于第二联接件333的圆柱轴，可以是固定设置于第一转接件332上的圆柱轴。
在操作杆31的作动端312施加作用力，连动端311移动，使得第一转接件332绕第二铰接部B相对于本体1的轴向摆动，经第二联接件333的传动，使得钉头部2跟随第一转接件332相对于本体1的轴向发生同向摆动第一角度；同时，齿轮传动组件32将第一转接件332绕第二铰接部B摆动传递给钉头部2，使得钉头部2绕第三铰接部C相对于第一转接件332发生同向摆动第二角度。最终，钉头部2相对于本体1的轴向摆动角度为第一角度和第二角度之和。
在本发明的替代实施方式中，操作杆31的连动端311与第一转接件332以其他方式相转动的连接或者固定连接，只要能实现操作杆31的连动端311能推动第一转接件332，使得第一转接件332相对于本体1轴向摆动即可。
在本发明的替代实施方式中，第一联接件331可以与本体1铰接，第一转接件332的近端与第一联接件331固定连接。也可以采用其他实施方式，只要能够实现使得第一转接件332相对于本体1的轴向摆动即可。
在本发明的替代实施方式中，第一转接件332的远端与第二联接件333的近端铰接，第二联接件333的远端与钉头部2固定连接。也可以采用实施方式，只要能够实现钉头部2相对于第一转接件332的摆动即可。
齿轮传动组件32的输入端与第一联接件331相对固定，齿轮传动组件32的输出端与 钉头部2相对固定；齿轮传动组件32的输出端相对于第三铰接部C的转动方向与第一转接件332相对于第二铰接部B的转动方向相同。
齿轮传动组件32的输入端为固定设置于本体1或第一联接件331的远端的第一齿部I。具体地，第一齿部I可以直接成形于第一联接件331的远端；或者作为独立部件固定设置于第一联接件331的远端。
在本发明实施方式中，在第一联接件331的远端固定连接一个独立部件，即定齿轮321，定齿轮321的远端一侧的齿部为第一齿部I。关于第一联接件331与定齿轮321的固定连接方式，参见图2、图4和图5，在本实施方式中，第一联接件331远端内部且靠近定齿轮321近端的位置固设一限位件3311，限位件3311与定齿轮321近端一侧的至少一个齿槽卡接配合。限位件3311可以是与齿槽卡接配合的凸块。在本发明的一个替代实施方式中，限位件3311与定齿轮321近端一侧的齿部啮合。
在本实施方式中，如图4和图5所示，定齿轮321套设于第二铰接部B的铰轴，并且夹设于第一联接件331与第一转接件332之间，以使结构紧凑。
在本发明的其他替代实施方式中，可以在第一联接件331远端的端面直接形成第一齿部I，还可以在第一铰接部B上直接形成第一齿部I，也可以采用其他方式形成与本体1、第一联接件331相对固定的第一齿部I。
齿轮传动组件32的输出端为固定设置于钉头部2的近端的第二齿部O。在本发明实施方式中，第二齿部O形成于钉头部2近端的端面，例如直接成形于钉仓架21的近端端面。在本发明的一个替代实施方式中，也可以在钉仓架21的近端固定连接一个第二定齿轮，第二定齿轮的近端一侧的齿部为第二齿部O。该第二定齿轮可以设置在第三铰接部C的位置(即第二定齿轮的心轴与第三铰接部C的铰轴重合，第二定齿轮套设于第三铰接部C的铰轴，绕铰轴旋转)。关于第二定齿轮与钉头部2的固定连接方式可以类似上述定齿轮321，在此不再赘述。
在本发明实施方式中，齿轮传动组件32为沿本体1的轴向设置的平行轴齿轮传动组件，该平行轴齿轮传动组件为直齿圆柱齿轮传动组件。该平行轴齿轮传动组件的各齿轮的轴心可以沿本体1的轴向布局成一条直线(如图1所示)，也可以布局成其他形状，例如三角形、或锯齿形等。本发明对齿轮轴的具体排布方式以及齿形不以此为限，例如齿轮轴可以是彼此相交型或交错型，齿形可以是直齿、斜齿或人字齿等。
齿轮传动组件32包括一个主动齿轮322和一个从动齿轮323。主动齿轮322和从动齿轮323的心轴都与第一转接件332相对固定。主动齿轮322的近端一侧与输入端第一齿部I啮合，其远端一侧与从动齿轮323的近端一侧啮合；从动齿轮323的远端一侧与输出端第二齿部O啮合。
在本实施方式中，主动齿轮322的心轴固定在第一转接件332上，具体的，主动齿轮322可转动地套设于第一转接件332上的固定轴P。
在本实施方式中，第一转接件332与第二联接件333之间通过一固定轴S固定连接， 如图4所示，从动齿轮323可转动地套设于固定轴S，从动齿轮323夹设于第二联接件333与第一转接件332之间，以使结构紧凑。
在本实施方式中，第一联接件331具有大致对称设置的两半，以本体1的中心轴为对称轴，一半设置在上方(图1和图2的俯视图所示的第一联接件331，另一半设置在下方(图3的仰视图中所示的第一联接件331)，第一联接件331的两半在附图中均统一标注成331，参见图4和图5。同样地，第二联接件333和第一转接件332也都具有大致对称设置的两半，附图中均分别统一标注成333、332，齿轮传动组件32与其中位于同侧的第一联接件331、第一转接件332和第二联接件333相连接即可。
在本发明的一个替代实施方式中，齿轮传动组件32包括一个主动齿轮322和一个从动齿轮组，该从动齿轮组由一个以上的奇数个依次啮合的从动齿轮组成，从动齿轮组的近端一侧与主动齿轮322啮合，远端一侧与输出端第二齿部O啮合。
在本实施方式中，第二铰接部B、主动齿轮322的轴心、从动齿轮323的轴心以及第三铰接部C的轴心都在同一条直线上。
在本实施方式中，第二铰接部B的轴心位于本体1的中轴线上；第三铰接部C的轴心位于钉头部2的中轴线上；第二铰接部B和第三铰接部C的轴心连线与第一转接件332的中轴线在同一直线上。
下面结合图2、图3、图6和图7，详细说明本发明实施方式的腔镜外科手术用缝切装置如何实现钉头部2和第一转接件332相对于本体1的轴向发生同向摆动。
参见图2和图3，为该装置的第一状态。钉头部2和第一转接件332相对于本体1没有发生摆动。在本实施方式中，在第一状态下，本体1、第一转接件332与钉头部2，三者基本同轴设置，即，本体1、第一转接件332、钉头部2，三者的中轴线基本在同一条直线上；另外，第二铰接部B、主动齿轮322的轴心、从动齿轮323的轴心以及第三铰接部C的轴心也都在这条直线上。
参见图6，为该装置的第二状态。当操作者向操作杆31的作动端312施加向远端的推动力时，连动端311沿本体1的壳体11向远端滑动；连动端311在第一铰接部A所在位置给第一转接件332施加了一个向远端的力，从而使得第一转接件332以第二铰接部B为转动中心相对于本体1的轴向逆时针摆动；与此同时，经第二联接件333的传动，使得钉头部2跟随第二联接件333、第一转接件332，也以第二铰接部B为转动中心相对于本体1的轴向逆时针摆动；与此同时，齿轮传动组件32将第一转接件332绕第二铰接部B相对于本体1轴向的逆时针摆动传递给钉头部2，使得钉头部2再进一步地绕第三铰接部C相对于第一转接件332发生逆时针摆动，从而钉头部2相对于本体1轴向可以逆时针摆动更大的角度。
关于齿轮传动组件32的传动过程，具体如下：由于定齿轮321固定连接于第一联接件321，因此定齿轮321远端的第一齿部I相对于第二铰接部B的轴心止转；当主动齿轮322的心轴和从动齿轮323的心轴一同跟随第一转接件322绕第二铰接部B逆时针摆动时， 止转的第一齿部I抵住主动齿轮322的近端一侧齿部，从而使得主动齿轮322绕其心轴逆时针自转，主动齿轮322带动从动齿轮323绕其心轴顺时针自转，从动齿轮323的自转输出到钉头部2上的第二齿部O，从而使得钉头部2再进一步地绕第三铰接部C相对于第一转接件332发生逆时针摆动。
参见图7，为该装置的第三状态。当操作者向操作杆31的作动端312施加向近端的拉动力时，连动端311沿本体1的壳体11向近端滑动；连动端311在第一铰接部A所在位置给第一转接件332施加了一个向近端的力，从而使得第一转接件332以第二铰接部B为转动中心相对于本体1的轴向顺时针摆动；与此同时，经第二联接件333的传动，使得钉头部2跟随第二联接件333、第一转接件332，也以第二铰接部B为转动中心相对于本体1的轴向顺时针摆动；与此同时，齿轮传动组件32将第一转接件332绕第二铰接部B相对于本体1轴向的顺时针摆动传递给钉头部2，使得钉头部2再进一步地绕第三铰接部C相对于第一转接件332发生顺时针摆动，从而钉头部2相对于本体1轴向可以逆时针摆动更大的角度。
关于齿轮传动组件32的传动过程，与上述的图6中的齿轮传动组件32的传动过程相反，在此不再赘述。
如图6或图7中所示，第一转接件332相对于本体1的轴向朝一侧摆动了第一角度，钉头部2相对于第一转接件332再进一步同向摆动了第二角度，因此，钉头部2相对于本体1的轴向朝一侧摆动了更大的角度，即第一角度和第二角度之和。通常在现有技术中，钉头部2相对于主体1的轴向朝任意一侧摆动的最大角度为45度左右，而在本实施方式的装置中，钉头部2相对于主体1的轴向朝任意一侧摆动的最大角度可以达到60度，并且通过调整齿轮的传动比可以获得更大的摆动角度，可以更好地满足腔镜外科手术的要求。
在本发明的替代实施方案中，钉头部2相对于第一转接件332摆动的角度可以大于第一转接件332相对于本体1摆动的角度，钉头部2可以有更大的摆动自由度。
应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施方式中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
