Description

一种镜头座、远端模块、内窥镜和方法 技术领域
本发明涉及一种内窥镜技术领域，尤其是涉及一种镜头座、远端模块、内窥镜和方法。
背景技术
内窥镜是一种常用的医疗器械，由可弯曲部分、光源及一组镜头组成。经人体的天然孔道，或者是经手术做的小切口进入人体内。使用时将内窥镜导入预检查的器官，可直接窥视有关部位的变化。图像质量的好坏直接影响着内窥镜的使用效果，也标志着内窥镜技术的发展水平。最早的内窥镜被应用于直肠检查。医生在病人的***内***一根硬管，借助于蜡烛的光亮，观察直肠的病变。这种方法所能获得的诊断资料有限，病人不但很痛苦，而且由于器械很硬，造成穿孔的危险很大。正因为有这些缺点，内窥镜检查一直在继续应用与发展，并逐渐设计出很多不同用途与不同类型的器械。
在公知的内窥镜中，用于对内窥镜观察区域进行照明和摄像单元的照相机和照明单元设置于内窥镜头部的远端。
虽然专利CN208724089U的内窥镜中，将光电耦合器和LED光源通过保护套集成为一体，通过灌封胶进行位置固定及密封，但该内窥镜中，需要同时包括透明灌封胶、黑色灌封胶，透明灌封胶设置在LED光源和保护套之间，黑色灌封胶设置在光电耦合器、导线和保护套之间。透明灌封胶覆盖了光电耦合器，由于光线透过透明灌封胶时将会产生折射，因此，对图像采集会造成一定的影响。
由于内窥镜头部远端的尺寸较小，因此，在内窥镜头部中总是需要节省空间，使得所需的组件可以有利地容纳于有限的空间中。并且在装入照明单元与 摄像单元时都是从后端往前端***，在这么狭小的空间内，通过后端***进行装配的难度很高，并且在装配时很容易造成照明单元和摄像单元的损伤。
发明内容
本发明的目的是提供一种更加方便的安装摄像单元与照明单元，并且不会损伤摄像单元与照明单元的镜头座、远端模块、内窥镜和方法。
本发明第一方面提供了一种镜头座，沿所述镜头座本体的轴向方向设置有摄像模组容纳部，所述摄像模组容纳部包括相机工作通道和照明工作通道；
所述镜头座本体的侧壁设有摄像模组开口部，所述摄像模组开口部包括相邻设置的第一开口部和第二开口部，所述第一开口部和所述相机工作通道连通，所述第二开口部和所述照明工作通道连通，所述第一开口部供相机模块装入，所述第二开口部供照明模块装入。
进一步的，所述第一开口部和所述第二开口部的部分开口方向相同。
进一步的，还包括操作通道，所述操作通道面向所述镜头座本体的侧壁上设置有第三开口部，所述第三开口部供操作管装入。
进一步的，所述镜头座本体的材料为透明材料，所述照明工作通道侧壁上涂敷有遮光层。
本发明第二方面提供了一种远端模块，包括摄像模组、所述的镜头座，所述摄像模组至少部分容纳于所述摄像模组容纳部内；
所述摄像模组包括摄像单元、发光单元和支撑单元，所述摄像单元和所述发光单元设置于所述支撑单元的同侧，所述摄像单元、所述发光单元和所述支撑单元一体设置。
进一步的，还包括套筒，所述套筒套设于所述镜头座的外周壁上。
进一步的，还包括镜片，所述镜片盖设于所述相机工作通道的顶端出口处。
进一步的，所述发光单元的顶端低于镜头座的前端。
本发明第三方面提供了一种内窥镜，包括手柄部和***部、所述***部包 括弯曲部和所述的远端模块，所述弯曲部与远端模块固定连接。
本发明第四方面提供了一种所述的远端模块的组装方法，包括如下步骤：
步骤S10：将摄像模组从摄像模组开口部装入摄像模组容纳部内；
步骤S20：将镜头座套筒套设于镜头座的外周壁上。
综上所述，本发明至少具有如下技术效果：
1.本发明通过设置镜头座，更加便于摄像模组的装入，有效避免了照明单元和摄像单元在装配时的损伤；
2.本发明通过在镜头座本体的轴向方向设置有摄像模组容纳部，镜头座本体的侧壁设置摄像模组开口部，从而便于将摄像模组从侧面装入镜头座本体，在方便摄像模组装入的同时，避免了摄像模组的损伤；
3.本发明通过设置第一开口部和相机工作通道连通，第二开口部和照明工作通道连通，使得相机模块和照明模块分别从侧面装入相机工作通道和照明工作通道，更加方便了一体式摄像模组的装入和定位；
4.本发明中当镜头座本体的材料为透明材料时，在照明工作通道侧壁上涂敷有遮光层，从而进一步防止照明单元渗光到内窥镜镜头座里边，避免了光线折射对图像采集的影响，提高了图像采集的质量。

实施例1：
本发明实施例1提供了一种镜头座100，沿所述镜头座本体110的轴向方向设置有摄像模组容纳部，所述摄像模组容纳部包括相机工作通道130和照明工作通道140；
所述镜头座本体110的侧壁设有摄像模组开口部，所述摄像模组开口部包括相邻设置的第一开口部131和第二开口部141，所述第一开口部131和所述相机工作通道130连通，所述第二开口部141和所述照明工作通道140连通，所述第一开口部131供相机模块装入，所述第二开口部141供照明模块装入。
本实施例中对述镜头座本体110的材质不做特殊限定，可为透明材质也可为不透明材质。
通过设置镜头座100，更加便于摄像模组的装入，有效避免了照明单元和摄像单元在装配时的损伤。
通过在镜头座本体110的轴向方向设置有摄像模组容纳部，镜头座本体的侧壁设置摄像模组开口部，从而便于将摄像模组从侧面装入镜头座本体，在方便摄像模组装入的同时，避免了摄像模组的损伤。
通过设置第一开口部131和相机工作通道连通，第二开口部141和照明工作通道连通，使得相机模块和照明模块分别从侧面装入相机工作通道和照明工作通道，更加方便了一体式摄像模组的装入和定位。
进一步的，所述第一开口部131和所述第二开口部141的部分开口方向相同。
如图4所示，与相机工作通道130连通的第一开口部和与照明工作通道140连通的第二开口部均面向上方设置有开口，从而保证摄像模组能够从同一个侧面装入，并且当摄像模组为一体设置时，进一步提高了装入的效率。
同时，与照明工作通道140连通的第二开口部的开口方向可扩展至相邻方向，如图4所示的左侧开口和/或右侧开口，左侧开口和/或右侧开口的设置便于工作人员对装入照明工作通道中的照明单元进行固定和位置调整，从而实现了摄像模组的定位和精确安装。
进一步的，还包括操作通道120，所述操作通道120面向所述镜头座本体110的侧壁上设置有第三开口部121，所述第三开口部121供操作管320装入。
所述操作通道120用于供操作管320装入，操作管320用于手术刀、钳等操作器械通过，同时也用于药液或者水等流体介质通过。
所述操作通道120的侧壁设置凹陷部，所述凹陷部与所述操作管320的外壁贴合设置，所述操作管320的端部低于操作通道120的前端。凹陷部的设置增强了对操作管320的固定和密封。
进一步的，所述镜头座本体110的材料为透明材料，所述照明工作通道130侧壁上涂敷有遮光层。
当镜头座本体的材料为透明材料时，在照明工作通道侧壁上涂敷有遮光层，从而进一步防止照明单元渗光到内窥镜镜头座里边，避免了光线折射对图像采集的影响，提高了图像采集的质量。
实施例2：
本发明实施例2提供了一种远端模块200，包括摄像模组210、所述的镜头座100，所述摄像模组210至少部分容纳于所述摄像模组容纳部内；
所述摄像模组210包括摄像单元211、发光单元212和支撑单元213，所述摄像单元211和所述发光单元212设置于所述支撑单元213的同侧，所述摄像单元211、所述发光单元212和所述支撑单元213一体设置。
摄像模组为一体设置，将一体设置的摄像模组从侧面装入镜头座本体，在避免损伤的同时实现了高效装配，有效提高了远端模块200装配的成功率和装配效率。
进一步的，还包括套筒220，所述套筒220套设于所述镜头座100的外周壁上。套筒220用于固定镜头座100和摄像模组210，并与内窥镜其他结构相连接。
进一步的，还包括镜片230，所述镜片230盖设于所述相机工作通道130的顶端出口处。所述镜片230用于保护摄像单元，延长摄像单元的使用寿命。所述镜片230上可设置有摄像套筒定位部。
进一步的，所述发光单元212的顶端低于镜头座100的前端。
通过设置发光单元212的顶端低于镜头座100的前端，能够防止照明单元发出的光折射至摄像头内，从而避免拍摄到的影像产生蓝光或者产生影像不清晰的现象。
实施例3：
本发明实施例3提供了一种内窥镜，包括手柄部和***部、所述***部包括弯曲部310和所述的远端模块200，所述弯曲部310与远端模块200固定连接。
手柄部和由弯曲部310、远端模块200共同组成的***部形成内窥镜，用于体内器官的检测。同时，内窥镜内还可以设置操作管320，通过操作管320进行采样或实现介质流通，以达到取样或治疗的目的。
实施例4：
本发明实施例4提供了一种所述的远端模块的组装方法，包括如下步骤：
步骤S10：将摄像模组210从摄像模组开口部装入摄像模组容纳部内；
步骤S20：将镜头座套筒220套设于镜头座100的外周壁上
通过将摄像模组210从位于镜头座本体侧壁的摄像模组开口部装入摄像模组容纳部内，从而使得摄像模组210从镜头座本体侧面装入，进而有效解决了狭小空间内装配难度高的问题，有效避免了装配时照明单元和摄像单元的损伤，在工业应用领域内有积极的实用意义。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
