进一步地，所述摄像装置20的前端、照明装置30的前端和器械管装置40的前端分别与所述壳体10的前端平齐。
上述方案中，在将所述壳体10、摄像装置20、照明装置30和器械管装置40注塑一体成型时，将所述摄像装置20的前端、照明装置30的前端和器械管装置40的前端分别设置的与所述壳体10的前端的表面平齐，不会突出于所述壳体10的前端的表面，避免了注塑时对照明装置30中的灯头和摄像装置20中的镜头表面产生损伤；但是摄像装置20的前端、照明装置30的前端和器械管装置40的前端在与所述壳体10注塑成型时，也不能低于所述壳体10的前端表面，避免摄像装置20在壳体10的内部产生的遮光使得拍摄的影像不清楚、照明装置30在壳体10的内部可照射的范围缩小。
进一步地，所述壳体10的前端设置有缩小部11，所述缩小部11的前端截面尺寸小于所述缩小部11的后端截面尺寸。
进一步地，所述缩小部11包括切面111和柱面112，所述切面111与所述壳体10的轴线夹角小于90°。
上述方案中，在所述壳体的前端设置有缩小部11，当内窥镜前端组件1在进入患者体内时，由于缩小部11由前端到后端的尺寸是由小到大，使得可以顺利到达病灶位置，且不会给患者带来不舒服的体验；其中，所述缩小部11的前端截面尺寸小于所述后端截面尺寸中，尺寸指的可以是面积，也可以是截面中柱面到切面的距离，也可以理解为切面111距离所述壳体10的轴线之间的距离。
如图4所示，所述切面111的外壁和所述柱面112的外壁连接组成了所述缩小部11的外壁，也可以理解为，所述缩小部11呈圆柱形，在所述缩小部11的顶部至底部向外在圆柱形上斜切掉了一个角之后所形成。所述切面111呈倒 等腰三角形，所述切面111和所述柱面112之间为圆弧过渡连接。为了能使前端组件在进入患者体内时避免出现不舒服的感觉，在设置切面111时，切面111的表面与所述壳体轴线的夹角需要小于90°，如30°、45°、60°等其它角度，具体的角度在此不做限制。
进一步地，所述连接件50与所述弯曲装置2的至少部分一体注塑成型。
上述方案中，将所述连接件50与所述弯曲装置2的至少前端部分采用一体注塑成型的方式进行连接，使得连接件50可以与所述弯曲装置2连接的更加牢固，且两者之间没有缝隙，弯曲装置2在进行弯曲的时候可以转动自如，避免了弯曲装置2从所述连接件5上脱落。
进一步地，摄像装置20包括摄像头21和第一信号线22，所述摄像头21和第一信号线22连接，所述摄像头21位于所述壳体10内，所述信号线至少部分位于所述壳体10内；所述照明装置30包括照明单元31和第二信号线32，所述照明单元31和所述第二信号线32连接，所述照明单元31位于所述壳体10内，所述第二信号线32至少部分位于所述壳体10内；所述器械管装置40至少部分位于所述壳体10内。
上述方案中，结合图2和图5所示，在将壳体10、摄像装置20、照明装置30和器械管装置40在模具中进行一体成型时，摄像头21连接有第一信号线22，所述摄像头21的全部和第一信号线22与摄像头21连接的一端与所述壳体10注塑成型，第一信号线22的另一端与内窥镜的把手连接；照明单元31连接有第二信号线32，所述照明单元31的全部和第二信号线32与照明单元31连接的一端与所述壳体10一体注塑成型，第二信号线32的另一端与内窥镜的把手连接；器械管装置40的前端与所述壳体10注塑成型，另一端也与内窥镜的把手连接。
进一步地，所述定位部51为定位块，所述定位块设置于所述连接件50的外壁上。
上述方案中，如图3所示，将定位部51设置为定位块，所述定位块可以通 过焊接、胶粘、插接等方式固定安装于所述连接件50的表面上。本实施例中，将定位部51和连接件50可选地采用一体成型的方式进行连接；所述定位块的截面形状可以为长方形、正方形、半球形等其它形状，在注塑时现将连接件50上的定位块与和弯曲装置2上对应的“L”型定位槽进行卡接，然后再将定位件50与所述弯曲装置2进行注塑成型，这样通过将连接件50和弯曲装置2之间通过先卡接再一体成型的方式的双重固定方式进行连接，使得连接件50和弯曲装置2之间的连接更加牢固，防止弯曲装置2在进行弯曲过程中与所述前端组件1之间发生脱离，导致内窥镜不能进行正常工作。
进一步地，所述连接件50的外壁上还设置有凹槽52，所述第一信号线22和/或第二信号线32可以通过所述凹槽52进入所述壳体10内。
上述方案中，如图3所示，在所述连接件50的外壁与所述摄像头21和/或照明单元31对应位置上设置凹槽52，设置的凹槽52可以在连接件50与所述壳体10一体注塑成型时，第一信号线22和/或第二信号线32放置在凹槽中，避免第一信号线22和/或第二信号线32与对应的摄像头21和照明单元31连接时发生扭曲，信号线发生折断的现象；在所述连接件50的外壁与所述摄像头21和/或照明单元31对应位置上设置凹槽52，也避免了所述第一信号线22和/或第二信号线32沿连接件50的外壁进行滑动，导致信号传输不稳定。
进一步地，所述器械管装置40包括沿所述壳体10的前端至后端依次设置的第一直线段41、弯曲段42、第二直线段43。
上述方案中，如图6和图7所示，所述器械管装置40为器械管本体，由于所述壳体10的前端设置了缩小部11，且缩小部11的前端截面尺寸小于所述后端截面尺寸，致使器械管本体在与缩小部11对应的位置需要向所述摄像装置20和照明装置30进行偏移，避免器械管本体的外壁露出所述壳体10的外壁，对通过所述器械管装置40中的钳子等设备在其中进行移动时，尖端戳破器械管装置40和壳体10，伤害到体内的其它组织。本实施例中，将所述器械管本体沿壳体10的前端至后端依次设置的第一直线段41、弯曲段42、第二直线段43， 所述弯曲段42和所述第一直线段位于所述壳体10中，所述第二直线段43部分位于所述连接件50中。
本实用新型还存在一种实施方案，对于内窥镜前端组件1的安装，首先将壳体10和所述连接件50一体注塑成型，然后再将摄像装置、照明装置、器械管装置通过点胶等其它方式固定安装在所述壳体10中，将所述弯曲装置2的前端与所述连接件50进行固定连接。
实施例二：
本实用新型实施例二提供了一种内窥镜，包括如实施例一所述的内窥镜前端组件1。
内窥镜前端组件安装与内窥镜的前端，用于进入患者的体内，找到并进入病灶位置，对患者的组织进行取样检查。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
