内窥镜是集中了传统光学、人体工程学、精密机械、现代电子、数学、软件等于一体的检测仪器。一个具有图像传感器、光学镜头、光源照明、机械装置等，它可以经口腔进入胃内或经其他天然孔道进入体内。利用内窥镜可以看到X射线不能显示的病变，因此它对医生非常有用。例如，借助内窥镜医生可以观察胃内的溃疡或肿瘤，据此制定出最佳的治疗方案。内窥镜中部分采用利用控制绳或钢丝绳控制端部夹持或弯曲的技术方案，但受限于胃镜的特殊结构，现有技术中内窥镜的绕线导线方式大都不能适用于胃镜结构中，故需提供一种适用于胃镜的绕线导线的方式。An endoscope is a testing instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. One has an image sensor, optical lens, light source illumination, mechanical device, etc. It can enter the stomach through the mouth or enter the body through other natural orifices. Using an endoscope can see lesions that X-rays cannot, so it is very useful for doctors. For example, an endoscopist can look at ulcers or tumors in the stomach and use this to determine the best treatment plan. Part of the endoscope adopts the technical solution of using a control rope or a wire rope to control the clamping or bending of the end, but due to the special structure of the gastroscope, most of the wire-winding methods of the endoscope in the prior art cannot be applied to the gastroscope structure. Therefore, it is necessary to provide a method for winding the wire of the gastroscope.

如图3所示，相邻两个管件单元211之间具有转动间隙210，所述管件单元211通过转动连接件212发生转动时，可使转动间隙210增大或减小。在两个管件单元211之间留有转动间隙210可在转动过程中起到让位的作用，使得转动过程更加流畅顺利。As shown in FIG. 3 , there is a
如图4所示，所述管件单元211内表面固定连接有若干个弧形套环6，相邻管件单元211上的弧形套环6依次排列形成限位通道7，所述控制绳贯穿过限位通道7。这样保证控制绳在转动过程中可几乎贴合在管件2的管壁上，对控制绳的位置起到规整作用。As shown in FIG. 4 , a plurality of arc-shaped
优选地，每一个管件单元211内设有至少四个弧形套环6，且弧形套环6沿管件单元211的轴心线周向均匀分布。两个处于相对位置的弧形套环6中贯穿的为压设在同一个驱动转盘上的控制绳，从而保证每一个驱动转盘单独控制管件2朝向一个方向转动。Preferably, each
结合图1和图3所示，所述管件2的横截面不为圆形。例如，所述管件2的横截面呈椭圆形，且管件2的周长为9π毫米-10.5π毫米。胃镜操作过程中，患者实际感受到管件的粗度与管件的周长相关，管件周长越大，患者感觉越粗，给患者带来的不适程度就越大，反之则越小。故将管件2的周长控制为直径为9毫米圆的周长到直径为10.5毫米圆的周长之间，可保证患者在插管过程中不适程度相对较低。As shown in FIG. 1 and FIG. 3 , the cross section of the
本发明，使用时，医护人员手持外壳体1，管件2的一端缓缓插入，直至患者胃部。由于本发明将管件2改为非圆形，例如为椭圆形，这样形状的管件2具有长径和短径，能够在提供足够的安装距离的同时，保证管件2本身具有较小的周长，减轻患者插管时的痛苦。In the present invention, when in use, the medical staff holds the outer casing 1, and one end of the
如图3所示，所述摄像组件23包括固定连接在管主体21上的摄像安装座231，所述摄像安装座231远离管主体21的一端设有摄像头232，所述摄像头232的一侧设有光源233。所述光源233为LED灯，所述摄像安装座231上还设有补光光源234，所述摄像头232的端部较光源233及补光光源234的端部更凸出于摄像安装座231的表面。采用LED灯相比于现有技术中常用的冷光源具有成本更低的优势，但其亮度不及冷光源，故添加一个补光光源234对光线进行补强。As shown in FIG. 3 , the
结合图3和图5所示，所述管主体21包括若干个依次连接的管件单元211，相邻两个管件单元211之间通过转动连接件212转动连接。这样可通过增加或减少管件单元211的数量以调节管主体21的整体长度，简单方便的满足了不同使用者的需求。Referring to FIG. 3 and FIG. 5 , the
具体的说，所述转动连接件212包括分别固定连接在相邻两个管件单元211上的第一连接部213和第二连接部214，所述第一连接部213一端设有表面呈圆弧形的连接头215，所述第二连接部214内具有与连接头215相配合的连接凹槽216，所述连接凹槽216靠近连接头215的一侧连通有开口217，所述开口217的最大宽度小于连接头215的外径。通过连接凹槽216与连接头215的相互配合使得相邻两个管件单元211之间可发生相对转动，进而使得管件2整体发生向一侧的弯曲，便于摄像头232调整视野。Specifically, the rotating connecting
优选地，所述连接凹槽216的两侧设有弧形导向臂218，所述连接头215侧面与管件单元211之间具有弧形导向凹槽219，所述连接头215嵌合在连接凹槽216内时，弧形导向臂218嵌合在弧形导向凹槽219内。弧形导向臂218与弧形导向凹槽219相互配合对两个管件单元211之间发生相对转动是进行导向纤维，保证转动过程的稳定性和可靠性。Preferably, arc guide
如图5所示，所述管件单元211上表面和下表面均为在竖直方向上具有连续起伏的弧面，所述第一连接部213的端部在竖直方向上的高度低于管件单元211下表面在竖直方向上高度的最低点，所述第二连接部214的端部在竖直方向上的高度高于管件单元211上表面在竖直方向上高度的最高点，相邻两个管件单元211之间具有转动间隙210。设计为具有高低起伏的弧面可便于第一连接部213和第二连接部214选择适宜的安装位置，进而方便了为两个管件单元211之间留出转动间隙210，使得转动过程更加流畅顺利。As shown in FIG. 5 , the upper and lower surfaces of the
如图5所示，每相邻两个管件单元211组成一个转动单元24，每个转动单元24包括两个相对设置的转动连接件212，相邻两个转动单元24的转动连接件212之间的连线相互垂直。一个转动单元24内的两个转动连接件212的连线与相邻的转动单元24内的两个转动连接件212的连线相互垂直，即两者的转动连接件212的相位相差90度，这样便于管件向前后和左右两个方向进行转动，需前后转动时，其中一个转动单元24内的一组转动连接件212承担发生相对转动的功能，需左右转动时，另一个与其相邻的转动单元24内的一组转动连接件212承担发生相对转动的功能。As shown in FIG. 5 , every two
