本发明涉及医疗器械技术领域，具体涉及一种内窥镜摄像头和内窥镜摄像系统。
背景技术
内窥镜摄像系统兼具第一成像光和第二成像光两种模式的显影能力，对于终端医疗机构来说，可实现设备一体化功能，即既能满足传统第一成像光内窥镜的临床需求，也能满足对病灶识别能力要求较高的第二成像光视野手术需求，有效减少手术室的设备配置并提升医院的科室诊疗能力。由于第二成像光摄像头同时具备第一成像光和第二成像光两种成像能力，这就要求摄像头内部必须包含第一成像光和第二成像光两个成像传感器，并将公共光路分为两条分光光路，第一成像光和第二成像光两个成像传感器分别位于两条分光光路上。

具体实施方式
目前现有的内窥镜摄像头产品主要存在三个明显缺点：(1)为满足光学镜片的安装定位精度，由于光路通道较为复杂，如光路通道由多个部件组合而成，镜片的安装过程往往需要装调实现，安装效率较低；(2)传感器实际成像区域未处于传感器中心，导致图像偏心，只能通过全屏显示、算法调教来解决偏心问题，牺牲了传感器的成像性能；(3)白光和荧光两个传感器的配准通过算法调教实现，未实现结构上的配准，为了消除机械安装定位误差造成的影响，只使用了较少部分成像区域，保证光线始终落在传感器成像面内，然后通过算法矫正两传感器成像区域位置，牺牲了传感器的成像性能，增大了系统的计算量。
针对上述问题，申请人对内窥镜摄像头做了如下改进以解决上述技术问题。
(1)将公共光路和分光光路设置为两个模块，两个模块分别安装在一个安装座上，两个安装座分别设有的公共光路通道和分光光路通道，公共光路通道和分光光路通道均为一体加工成型的孔道，其中公共光路通道为安装孔，安装孔包括孔径大小依次阶梯变化的阶梯段，相比拼接安装的公共光路通道，一体加工成型的安装孔各阶梯段之间具有良好的同轴度，使得安装在公共光路通道中的光学镜片更容易提高同轴度的精度，同时还能够降低安装难度，进而提高安装效率。
(2)第一成像传感器(白光传感器)和第二成像传感器(荧光传感器)通过安装支座安装在 分光光路安装座，其中安装支座与分光光路安装座之间为可调节安装，第一成像传感器和第二成像传感器分别与安装支座之间也为可调节安装，使得第一成像传感器和第二成像传感器分别通过安装支座能够实现轴向位置调节、倾斜角度调节、径向位置调节，进而能够解决图像偏心的问题，进而能够有效发挥第一成像传感器和第二成像传感器的成像性能。
(3)第一成像传感器和第二成像传感器通过安装支座安装在分光光路安装座，其中安装支座与分光光路安装座之间为可调节安装，第一成像传感器和第二成像传感器分别与安装支座之间也为可调节安装，使得第一成像传感器和第二成像传感器分别通过安装支座能够实现径向位置调节和轴向转动调节，以第一成像传感器作为基准，先调节第一成像传感器的对中位置，再调节第二成像传感器的径向位置和转动位置，进而能够使得第一成像传感器生成的第一成像光图像(白光图像)和第二成像传感器生成的第二成像光图像(荧光图像)对齐适配重合，以使得光线尽可能的落在第一成像传感器和第二成像传感器的感应区域内，进而能够有效发挥第一成像传感器和第二成像传感器的成像性能，及降低系统的计算通量。
上述方案中，第一成像传感器和第二成像传感器的调节均为在生产安装过程中的调节，以使得第一成像传感器和第二成像传感器能够安装到预设的准确位置上。出厂后，第一成像传感器和第二成像传感器均为固定结构，不能随意调节位置；若在长时间使用或意外事故导致第一成像传感器和第二成像传感器位置出现移动时，专业的组装人员可以对第一成像传感器和第二成像传感器的安装位置进行调节维护，维护后的第一成像传感器和第二成像传感器也处于固定的状态。即上述方案中对传感器的位置可以在安装或维护过程中进行调节，在使用过程中不能进行调节。
