实施例2
本实施例的主要技术方案与实施例1或者实施例2基本相同，在本实施例中未作解释的特征，采用实施例1或者实施例2中的解释，在此不再进行赘述。本实施例1与实施例2的区别在于：
如图2、图3所示，铰接环组212包括多个铰接环，多个铰接环两两铰接，通过两两铰接的连接形式，使所有的铰接环连接成一条完整的铰接环组212铰接环的上端的沿第一径向设置两个第一铰接耳2121，第一铰接耳2121与相邻的铰接环铰接，铰接环的下端的沿第二径向设置第二铰接耳2123，第二铰接耳2123与相邻的铰接环铰接，第一径向与第二径向垂直。铰接耳和铰接孔分别设置于横向和纵向，同一铰接环的铰接轴2122轴心线和铰接2124孔的中心线相互垂直，因此相邻的两个铰接摆动方向相互垂直，仅仅通过3个铰接环即可形成万向连接，实现铰接环组212的万向弯曲。
通过设置第一铰接耳2121和第二铰接耳2123使连接部位突出于铰接环，铰接环组212弯曲时，相邻铰接环具有较大的旋转空间，在旋转到预定角度之前不会发生卡位或者碰触，铰接环组212具有较大的弯曲角度，使用内窥镜观察时，可使前端部1按照所需要的角度弯曲。
具体来说，铰接环的上端沿直径相对位置设置弧形凹位，两个凹位之间形成第一铰接耳2121，第一铰接耳2121的外侧设置铰接轴2122，铰接环的下端沿直径方向的相对位置设置弧形凹位，两个凹位之间形成第二铰接耳2123，第二铰接耳2123设置铰接孔2124，铰接轴2122的轴心线与铰接孔2124的中心线相互垂直，相邻铰接环铰接时，铰接轴2122与铰接孔2124铰接，凹位的作用在于容纳铰接环旋转，使铰接环具有较大的旋转角度，即铰接环组212具有较大的弯曲角度。部分内窥镜插入组件为求较大的旋转空间和弯曲角度，铰接的单体镂空部分多，铰接环组212弯曲之后，部分控制线缆张紧，部分控制线缆松弛，容易导致松弛的控制线缆伸出到铰接环组212之外，易导致控制线缆卡于铰接环组212，本发明结构在具有较大的弯曲角度的同时，铰接环连接密致，整体结构紧致，镂空部少，控制线缆被大部分位置被铰接环包围，松弛的控制线缆不易伸出铰接环外，为控制线缆提供了一个安全可靠的工作环境。
铰接环的上端外壁设置外环槽2126，下端的内壁设置内环槽2125，第一铰接耳2121插入相邻的铰接环的内环槽2125内，第二铰接耳2123套设于相邻 的铰接环的外环槽2126。通过设置外环槽2126和内环槽2125使相邻的铰接环保持结构的一致性，铰接环组212的最大直径与铰接环的直径相等，避免铰接环组212的侧壁形成凸出结构，减少铰接环组212插入的阻力，同时减轻患者插入内窥镜时的呕吐反应。
本实施例中外环槽2126和内环槽2125设置可倒置，即铰接环的下端端外壁设置外环槽2126，上端的内壁设置内环槽2125，第一铰接耳2121套设于相邻的铰接环的外环槽2125外，第二铰接耳2123插入相邻的铰接环的内环槽2126内，倒置设置与上述非倒置设置技术效果相同。
设置两个用于穿引控制线缆的穿线孔2127，两个相邻的铰接环形成横向和纵向的四个穿线孔2127，从四个方向安装固定控制线缆。控制线缆的一端连接控制部，另一端穿过穿线孔2127后连接远端接头213。
本实施例中，第一铰接耳2121和第二铰接耳2123明显会突出于铰接环的上端面和下端面，第一铰接耳2121和第二铰接耳2123分别与相邻的铰接环铰接后，会预留出较大的旋转空间，相邻的铰接环绕铰接点旋转时具有较大旋转空间，本实施例的内窥镜插入组件具有较大的弯曲角度、观察范围。
本实施例的铰接环为塑料件，塑料件的生产速度快，相比于金属材质的蛇骨结构或者等距弹簧具有成本低，而且，塑料件具有回收成本低，再生能力强，非常适用于一次性使用的插入组件和一次性使用的内窥镜。
实施例3
本实施例的主要技术方案与实施例1或者实施例2基本相同，在本实施例中未作解释的特征，采用实施例1或者实施例2中的解释，在此不再进行赘述。本实施例1与实施例2的区别在于：
如图4所示，本实施例与实施例2不同之处在于所述第一铰接耳2121设置铰接轴2122，所述第二铰接耳2123设置安装槽，所述安装槽包括铰接孔2124和用于引导所述铰接轴2122装入所述铰接孔2124的安装通道2128，所述安装通道2128竖直设置，所述安装通道2128的入口设置于第二铰接耳2123 的顶端，本实施例中，由于第二铰接耳2123倒立设置，其顶端即是第二铰接耳2123的最下端，所述安装通道2128的出口设置于铰接孔2124的最低点处。所述铰接轴2122的轴心线和铰接孔2124的中心线垂直。通过安装通道2128快速安装铰接环，通过安装通道2128的引导使铰接轴2122从第二铰接耳2123的顶端通顺着安装通道2128从出口处进入铰接孔2124，避免通过外力挤压使铰接环变形来使铰接轴2122装入铰接孔2124，且本实施例安装通道2128最短，通道结构简单，安装速度快。
本实施例中，所述安装通道2128的入口宽度大于所述安装通道2128的出口宽度。增加入口宽度，便于铰接轴2122进入安装通道2128，缩小出口处的宽度，防止铰接轴2122从安装通道2128滑出。
所述铰接轴2122的外端设置挡块2129，所述挡块2129的横向或者纵向尺寸大于铰接孔2124的直径，本实施例中，挡块2129为圆形的挡块2129，圆形的档块2129的直径大于铰接孔2124的直径。铰接环为塑料件，存在形变，通过控制线缆控制插入组件弯曲时，易使铰接环形变，存在铰接轴2122脱离铰接孔2124的可能，本实施例中挡块2129的直径大于铰接孔2124的直径，限制因铰接环变形而导致铰接轴2122沿铰接孔2124的中心线滑动，防止铰接轴2122从铰接孔2124滑脱。
实施例4
本实施例的主要技术方案与实施例1或者实施例2基本相同，在本实施例中未作解释的特征，采用实施例1或者实施例2中的解释，在此不再进行赘述。本实施例1与实施例2的区别在于：
如图5所示，与实施例2相比，本实施例不同之处在于，本实施例安装通道2128倾斜设置，为倾斜直通道，所述安装通道2128的入口设置于第二铰接耳2123的侧边，所述安装通道2128的出口设置于铰接孔2124的最低点和最高点连线的一侧，且入口和出口设置于最低点和最高点连线的同一侧。
第二铰接耳2123包括相对设置的两个铰接耳，两个铰接耳的安装通道2128的朝向可相同或者相反。
本实施例中，由于安装通道2128的出口位置偏离最高点和最低点，插入组件无论是处于弯曲还是处于伸直状态，铰接轴2122不易从安装通道2128滑出。
如图6所示，本实施例安装通道2128呈钩状设置，所述安装通道2128的入口和出口设置相同，由于安装通道2128弯曲，形成安装通道2128于出口出与铰接孔2124的孔壁垂直，开口宽度更小，相比与斜直通道更不容从安装通道2128滑出。
本发明的插入组件在控制部的控制线缆上套接有用于控制支撑组件弯曲方向和角度的等距弹簧，所述控制部的控制线缆连同所述等距弹簧依次穿设于所述近端接头、铰接环组，与所述远端接头固定连接，所述等距弹簧的近端与所述近端接头固定连接，所述等距弹簧的远端与所述远端接头固定连接。本发明通过套接有等距弹簧的控制线缆控制前端部进行一定弯曲方向和弯曲角度范围内的万向转动，并且实现自由弯曲和快速复位。
以上所述，仅为本发明较佳的具体实施方式，但本发明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发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求的保护范围为准。
