具体实施方式
以下的说明提供了许多不同的实施例、或是例子，用来实施本发明的不同特征。以下特定例子所描述的元件和排列方式，仅用来精简的表达本发明，其仅作为例子，而并非用以限制本发明。
内窥镜常用来看X射线不能显示的病变，可为医生提供充分的诊断信息以治疗疾病，但将同一内窥镜在不同患者之间的应用时很容易导致交叉感染。一次性内窥镜虽然可以避免交叉感染问题，但一次性内窥镜使用成本高，且不利于环保。内窥镜常可为纤维内窥镜和电子内窥镜。
纤维内窥镜由内窥镜镜体和冷光源两部分组成，镜体内设有导光束和导像束，导光束是用来将冷光源产生的光线传导到被观测的物体表面，将被观测物表面照亮；导像束是把数万根直径在1微米以下的光导纤维按序排列成一束，将导像束的一端对准目镜，另一端对准病灶表面，医生通过目镜能够直观地看到病灶位置的情况。
电子内窥镜以光敏集成电路摄像系统(简称CCD芯片)传像代替光纤传像。CCD芯片可以将病灶图像通过CCD面阵进行逐点、逐行、逐帧依次转换、存储、传输，在其输出端产生一个病灶图像相关的时序视频信号经电缆传输至外部电路转换处理系统，再经取样、A/D转换、数字信号处理、D/A转换、电视信号编码，最后在监视器上还原成可供观察的病灶图像和相关文字信息。有些电子内窥镜还设有微型集成电路传感器，将所观察到的信息反馈给计算机，其 不但能获得组织器官形态学的诊断信息，而且也能对组织器官各种生理机能进行测定。与纤维内窥镜相比，电子内窥镜所显示的图像质量更高，光亮度强，具有更高的分辨率，可以检查出更细小的病变；且电子内窥镜的外径更细，更便于医生的操作。因此，电子内窥镜具有着更为广泛的应用前景。
在内窥镜中，最为昂贵的部件即为摄像头模组，现有技术中的摄像头模组整体封装于内窥镜的远端，如果能对摄像头模组进行回收将会大大的降低内窥镜的丢弃成本。
鉴于此，本发明的一个实施例，如图1、图2所示，提供了一种一体化成像组件，所述一体化成像组件1包括：物镜11、图像传感器12、导像束13；所述导像束13包括探头端131和把手端132；
如图1所示，所述导像束13的探头端131固定连接于所述物镜11，所述导像束13的把手端132固定连接于所述图像传感器12，所述导像束13为光纤；
上述方案中，根据光学的全反射原理，采用光纤作为导像束13。将光纤的一端固定连接于所述物镜11，光纤的另一端固定连接于所述图像传感器12。
实际应用中，将物镜11封装于内窥镜的远端的探头端131，将图像传感器12容置于内窥镜的近端的把手端132，将光纤封装于内窥镜主体内；内窥镜的远端物镜11将采集到的病灶的光信号经光纤传递给图像传感器12，图像传感器12再将接收到的光信号进行一系列转化，最后生成图像信号，在显示器上进行显示。
优选地，在光纤的外面被覆一层折射率较低的膜，以保证光纤传导的光线都能发生全反射。
需要注意的是，现有技术中常规的方式是将物镜11和图像传感器12均封装于内窥镜的远端，物镜11和图像传感器12是仅连接于导像束13的一端的；因此，将物镜11和图像传感器12分别固定连接于导像束13的两端，这对本领域技术人员来说是不容易想到的。且现有技术中由于将物镜11和图像传感器12均封装于内窥镜的远端，而由图像传感器12传感器转换生成的信号为电信 号，其只能在电信号传输线中传输；因此，现有技术中的导像束必须采用电信号传输线，因此，将导像束13更换为光纤这对本领域技术人员来说也是不容易想到的。
如图2所示，或所述物镜11与所述图像传感器12连接为一体，所述导像束13的探头端131与所述图像传感器12固定连接，所述导像束13为电信号传输线。
上述方案中，将物镜11和图像传感器12整体封装于内窥镜的远端的探头端131，将导光束封装于内窥镜主体内；位于内窥镜远端的物镜11将采集到的目标物体的光信号直接传递给图像传感器12，图像传感器12再将接收到的光信号转化为电信号，经导像束13传递给最后生成图像信号，在显示器上进行显示。
需要注意的是，本实施例与现有技术最大的不同在于：现有技术中的内窥镜的成像组件，不是一体设置的，其不可以整体从内窥镜中整体抽离出来，而上述两个方案中的成像组件为一体化设置，即物镜11、图像传感器12、导像束13形成一个整体，其可以作为一个单独的组件容置于内窥镜中使用，也可以整体从内窥镜中抽离出来，经消毒处理后再重复利用。如此，便可以实现对内窥镜成像组件的单独回收，大大降低了内窥镜的抛弃成本。
进一步地，如图3-图6所示，所述一体化成像组件1还包括镜头座14，所述物镜11容置于所述镜头座14内。
上述方案中，设置镜头座14的目的是，便于物镜11在内窥镜远端的安装与拆卸。实际应用过程中，将物镜11容置于所述镜头座14内，只需要将镜头座14与内窥镜的远端连接即可实现对物镜11和或图像传感器12的固定。
本发明另一个实施例，如图3-图6所示，提供一种内窥镜，该内窥镜包括内窥镜主体2、前述的一体化成像组件1，所述内窥镜主体2内设有成像通道21，所述一体化成像组件1容置于所述成像通道21内，所述一体化成像组件1可整体抽离所述成像通道21。
上述方案中，通过将前述成像组件容置于所述内窥镜的成像通道21内，回收时，将所述一体化成像组件1整体抽离所述成像通道21，实现对成像组件1的回收利用，整个操作简单方便。相比于现有技术中的内窥镜，本实施例中内窥镜抛弃成本低，更为环保节约。
进一步地，所述内窥镜主体2包括探头侧22和把手侧，所述成像通道21连通所述探头侧22和所述把手侧；以下方案中，给出了两种一体化成像组件1在内窥镜中的布置形式。具体地，
所述物镜11设置于所述探头侧22，所述图像传感器12设置于所述把手侧，所述导像束13容置于所述成像通道21内；通过此种布置方式，首先可以实现对成像组件的整体回收；其次，由于图像传感器12位于内窥镜的把手侧，进一步避免了图像传感器12被污染的风险，便于对图像传感器12单独的回收利用。
或所述物镜11和所述图像传感器12均设置于所述成像通道21的探头侧22，所述导像束13的探头端131与所述图像传感器12连接，所述导像束13容置于所述成像通道21内；从而实现对成像组件的整体回收。
进一步地，如图5所示，所述内窥镜的把手侧设置有插入口231，所述一体化成像组件1可整体从所述插入口231穿过所述成像通道21；
和/或所述内窥镜的探头侧22设置有插入口231，所述一体化成像组件1可从所述插入口231抽离出所述成像通道21。
上述方案中，通过插入口231，将所述一体化成像组件1整体从内窥镜中抽离，实现成像组件1的回收利用。所述插入口231的位置可以设置于内窥镜主体的把手侧(如图5)，也可以设置于内窥镜主体的探头侧22(未图示)。
当然，在所述内窥镜的把手侧的末端还设有可拆卸的把手盖(未图示)，所述把手盖与内窥镜的把手可拆卸连接。当需要将所述一体化成像组件从内窥镜主体1的把手侧抽离时，需要先打开把手盖。
进一步地，如图7所示，所述内窥镜还包括镜头盖24，所述镜头座14上设有第一连接结构141，所述镜头盖24上设有第二连接结构241，通过所述第 一连接结构141和所述第二连接结构241的连接，实现所述镜头座14与所述镜头盖24的抵接。
当将所述一体化成像组件1容置于所述内窥镜中时，需要对成像组件进行定位。具体地，通过将镜头座14相对于内窥镜镜头盖24的定位(即第一连接结构141和第二连接结构241)，实现对一体化成像组件1在内窥镜主体2内的定位。
至于具体实现镜头座14与镜头盖24连接的结构，可以为卡扣结构；如在镜头座14(或镜头盖24)上设置弹性凸起，在镜头盖24(或镜头座14)的对应位置上设置凹槽，当弹性凸起卡入凹槽内时，镜头座14与镜头盖24之间相对固定；当拉动镜头座14(或镜头盖24)时，弹性卡扣从凹槽中脱离，实现镜头座14与镜头盖24之间的脱离，此时，便可将一体化成像组件1整体从内窥镜主体2中分离。
进一步地，所述成像通道21上设有导向结构(未图示)，所述导向结构用于引导所述一体化成像组件1通过所述成像通道21。
当所述一体化成像组件1从内窥镜的把手侧分离出内窥镜主体2时，所述物镜11(或“物镜11与图像传感器12”)需穿过整个成像通道21。在成像通道21内设置导向结构，可以引导所述一体化成像组件1按预定的路径通过所述成像通道21，实现一体化成像组件1的顺利抽离。
进一步地，如图8所示，所述内窥镜还包括照明组件25；
所述照明组件25与所述一体化成像组件1一体设置，所述照明组件25可随所述一体化成像组件1穿过所述成像通道21；
或所述照明组件25与所述内窥镜主体2一体设置。
进一步地，所述照明组件25布置于所述物镜11的周向。
照明组件25用于为一体化成像组件1提供光源。上述方案中，将所述照明组件25与所述一体化成像组件1一体设置，在从内窥镜中分离所述一体化成像组件1时，可以同时实现照明组件25的分离，实现照明组件25的回收利用。 优选地，照明组件25可以设置多个，其排布于物镜11的周向。
如图9所示，本发明另一个实施例，提供一种前述的内窥镜回收方法，图中箭头为一体化成像组件的抽离方向。该方法包括如下步骤：
步骤S01：将所述一体化成像组件1从所述内窥镜主体2整体抽离；
步骤S02：将抽离出来的一体化成像组件1消毒后单独回收，内窥镜其余部分做废弃处理。
上述方案中，通过将一体化的成像组件整体从内窥镜中抽离，实现对内窥镜较为昂贵的成像组件的回收利用，内窥镜的其余部分做废弃处理，操作简单方便，大大降低了内窥镜的抛弃成本。
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。
