 本发明的实施方式
下面结合附图和实施例对本申请的实施方式作进一步详细描述。以下实施例用于说明本申请，但不能用来限制本申请的范围。
在本申请实施例的描述中，需要说明的是，术语“中心”、“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请实施例和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请实施例的限制。此外，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。本申请实施例中所述的“远端”指长管插入部30远离操作部40，“近端”为长管插入部30靠近操作部40。
如图1和图2所示，在一实施例中，提供了一种3D电子内窥镜摄像系统1000，包括光源10、导光束20、电子镜、线缆71、摄像主机50、显示器60和视频连接线72。
电子镜是3D电子内窥镜成像系统1000的重要组成部件，包括插入部30和操作部40，插入部30和操作部40可以为一体结构。其中，插入部30包括长管32、摄像模组31，照明光路和传输部70。长管32可以是根外表面相对光滑，内部中空的圆形长管，长管32会伸入到检查对象100体内，因此长管32外径需尽可能的小，如≤10.5mm，在一实施例中，长管32可以制作为非正圆管，如椭圆管；摄像模组31设置在长管32内部远离操作部40的部分，即摄像模组31设置在长管32远端，用于接收获取到的检查对象100特定部位反射或激发的图像光，并将图像光转化为电信号，并通过传输部70将电信号传输到操作部40中。具体而言，3D电子内窥镜镜的摄像模组31有两路光路，配有第一光路组件和第二光路组件，第一光路组件接收左侧或右侧的图像光，第二光路组件接收另一侧图像光，左侧图像光与右侧图像光分别传输到两个传感器314（第一传感器314a、第二传感器314b）上，为保证最后的三维成像效果，优选两个相同型号的传感器，第一传感器314a和第二传感器314b将各自采集到的第一路图像光和第二路图像光分别转化为第一电信号和第二电信号，并通过传输部70分别将第一电信号和第二电信号传输至操作部40；照明光路用于与导光束20对接，用于将光源10传输的光照射至检查对象100的特定部位；传输部70与操作部40对接，用于将传感器314输出的电信号传输至操作部40。操作部40包括操作手柄外壳、控制器和图像信号处理组件41，控制器用于根据操作者输入的信号实现不同功能，可以实现功能，如：模式转换功能、对焦功能、校色功能、照明开关功能等；图像信号处理组件41将传输部70传输来的第一电信号和第二电信号进行处理，并得到第一图像信号和第二图像信号，并将第一图像信号和第二图像信号传输到摄像主机50中；图像信号处理组件可以对接收到的电信号进行中继处理、串并转换、差分传输处理等。在另一实施例中，第一图像信号和/或第二图像信号可通过至少一个图像信号转换单元将至少部分电信号转化为非电信号，如光信号。
显示器60会显示出检查对象100的特定部位的图像，经由3D电子内窥镜获取的左右两侧图像光经过处理后，如：偏振处理等，检查对象100的特定部位对应图像会显示在显示器60上，观测者需佩戴偏振眼镜进行观测，并最终观测到三维立体图像。
在3D电子内窥镜中也可以设置信号放大电路33，信号放大系统33设置在摄像模组31和图像信号处理组件41之间，用于将摄像模组31输出的电信号进行放大，保证电信号在传输过程中不至于过分衰减，导致影响最终成像效果。
摄像主机50通过线缆71与3D电子内窥镜相连接，3D电子内窥镜生成的图像信号通过线缆71传输至摄像主机50内进行处理。在某些实施例中，线缆71可以为光通信线缆，如光纤，3D电子内窥镜将图像信号（电信号）转化为光信号，由线缆71传输到摄像主机50，摄像主机50再将光信号转换成电信号（图像信号）。在另一实施例中，线缆71也可以为光电复合缆，3D电子内窥镜将部分电信号转化为光信号，保留部分电信号，通过线缆71传输到摄像主机50上进行处理。在另一实施例中，3D电子内窥镜也可以通过无线传输将图像信号发送至摄像主机50上进行处理。
本领域技术人员应当理解的是，图1仅是3D电子内窥镜摄像系统的示例，并不构成对3D电子内窥镜摄像系统的限定，3D电子内窥镜摄像系统可以包括比图1所示更多或更少的部件，或者组合某些部件，或者不同的部件。
在一实施例中，光源10用于向待观察部位提供照明或激发光源。光源包括白光光源（照明光源），在另一实施例中，光源10也可包括对应于荧光试剂的激发光光源（激光光源，例如近红外光）。
在一实施例中，摄像主机50内设有处理器，摄像主机50通过线缆71与电子镜连接，用于获取电子镜输出的图像信号。处理器获取到电子镜输出的图像信号后，将对图像信号进行处理，以输出被观察组织的白光图像或荧光图像。其中获取的图像信号可以为单独的白光信号或荧光信号，也可以为白光信号和荧光信号合并的图像信号。
本申请实施例提供一种3D电子内窥镜摄像头。可以用于上述任意一实施例提供的3D电子内窥镜摄像系统1000中。
3D电子内窥镜包括操作部40和插入部30，插入部30和操作部40可以为一体结构，共同构成医用内窥镜摄像头。其中，插入部30包括长管32、摄像模组31，照明光路和传输部70；长管32为内部中空的管状结构，摄像模组31设置在长管32的内部；照明光路和传输部70设置在长管32内部；照明光路用于将光源10的光照射至检查对象100的特定部位。在一实施例中，光源10和3D电子内窥镜通过导光束20连接；在另一实施例中，光源10设置在3D电子内窥镜远端。
摄像模组31用于接收插入部30远端获取的特定部位反射或激发的图像光，并将图像光转化为电信号，通过传输部70将电信号传输到操作部40中；
操作部40包括操作手柄外壳、控制器和图像信号处理组件41；控制器用于根据操作者输入的信号实现不同功能；图像信号处理组件用于对传输部70传输来的电信号进行处理，以得到图像信号。在其他一实施例中，操作部40还可以包括图像信号转换单元，用于将图像信号转化为其他非电信号。
如图4所示，摄像模组31包括第一光路组件、第二光路组件、第一传感器314a、第二传感器314b、第一软板315a、第二软板315b和固定基板316。第一软板315a和第二软板315b承担着电路板的功能，将电信号传输到传输部70。如图5所示，在一实施例中，固定基板316也可以是多块合在一起，形成一个整体。在另一实施例中，固定基板316也可以采用陶瓷板，或金属板；陶瓷板工艺成熟、价格适中，是制作医用内窥镜的常规材料，而选用金属板可以方便导热，将传感器314上的热量导向长管。
第一光路组件包括第一物镜组311a和第一棱镜组312a，第二光路组件包括第二物镜组311b和第二棱镜组312b；第一物镜组311a用以接收特定部位反射或激发的第一路图像光；第一棱镜组312a用以将第一路图像光反射或透射至第一传感器314a上；第一传感器314a与第一软板315a电连接，并将第一路图像光转化为第一电信号；第二物镜组311b用以接收特定部位反射或激发的第二路图像光；第二棱镜组312b用以将第二路图像光反射或透射至第二传感器314b上；第二传感器314b与第二软板315b电连接，并将第二路图像光转化为第二电信号；
第一软板315a和第二软板315b与传输部70电连接，将第一电信号和第二电信号传输至传输部70；第一传感器314a和第二传感器314b分别设置在固定基板316的两侧，第一传感器314a和第一软板315a设置在固定基板316的同一面，第二传感器314b和第二软板315b设置在固定基板316的另一面。固定基板316的硬度或刚度强于第一软板315a或第二软板315b，为第一软板315a或第二软板315b提供支撑力。相较于常规的硬板，本申请实施例可以通过调整第一软板315a或第二软板315b的位置来调整和第一软板315a或第二软板315b相连接的第一传感器314a或第二传感器314b的相对位置，更加方便对准第一传感器314a和第二传感器314b的相对位置，方便校准，提高成像质量。
在一实施例中，传感器314可以采用CSP传感器或COB传感器等，在本申请中，优选如图3所示的COB传感器，因为，相较于常规医用内窥镜采用的CSP传感器，COB传感器体积更小、更薄并使用金线焊接，而CSP传感器体积更大，通过底部焊接球进行焊接。使用COB传感器可以有效减小设置传感器314所需体积，释放更多空间给光学镜组，使得光学镜组最大化，获取更多图像光。传感器四周设置有第二焊接部，在软板上设置有与第二焊接部3142对应的第一焊接部，将第一焊接部和第二焊接部3142焊接，得以实现软板和传感器电连接。
摄像模组31是内窥镜摄像头成像的重要部件，摄像模组31越大越能接收到更多的光信号，进而呈现出高质量观测图像，但由于摄像模组31设置在长管32内部，受到长管32直径限制，摄像模组31能够布置的空间有限，本申请的实施例通过合理布置摄像模组31内部元件结构，实现感光面积最大化，保证成像质量。
在一实施例中，第一传感器314a、第一软板315a、固定基板316、第二软板315b和第二传感器314b层叠设置，各个部件的位置可以对应在一条线上，也可以错落叠放。
在一实施例中，第一软板315a上设置有通孔结构，第一传感器314a设置在通孔中；或/和第二软板315b上设置有通孔结构，第二传感器314b设置在通孔中。通孔中可以设置金属板或其他材料的基板，给设置在通孔中的传感器支撑力。
在一实施例中，第一棱镜组312a包括直角棱镜或三角棱镜；或/和第二棱镜组312b包括直角棱镜或三角棱镜，第一棱镜组312a和第二棱镜组312b中的棱镜数量不做限定，可以是一个或多个。
在一实施例中，第一棱镜组312a的出光端面为矩形，矩形的长边与长管轴向方向一致，短边垂直于长管轴向方向；或/和第二棱镜组312b的出光端面为矩形，矩形的长边与长管轴向方向一致，短边垂直于长管轴向方向。在一特殊实施例中，长边等于短边，即出光端面为正方形。在另一实施例中，出光端面的长边大于短边。在一实施例中，第一棱镜组312a和/或第二棱镜组312b中的棱镜的短边大于等于高度，长边大于等于短边，可充分利用棱镜高度，以实现有效像面的最大化，进而输出较高分辨率的画面，棱镜的短边小于等于长边，同样是为了保证棱镜组的反射面得到充分利用，尽可能输出更多图像光，以实现较大的分辨率输出。
在一实施例中，第一棱镜组312a或/和第二棱镜组312b的出光端面上还可以增加光阑，光阑设置在第一棱镜组312a或/和第二棱镜组312b出光端面上，通过光阑遮挡部分不能传播到感光区域3141的图像光，可以防止光线间相互干扰，影响传感器314的准确，出现炫光、鬼影等影响成像效果。
在一实施例中，第一传感器314a的感光面上的感光区域3141大于或等于第一棱镜组312a的出光端面；或/和第二传感器314b的感光面上的感光区域3141大于或等于第二棱镜组312b的出光端面。为保证成像效果，需要传感器接收到尽量多的光信号。
在一实施例中，第一棱镜组312a的出光端面设置在第一传感器314a的感光面上，并且第一传感器314a的至少部分感光区域3141处于封闭空间中；或/和第二棱镜组312b的出光端面设置在第二传感器314b的感光面上，并且第二传感器314b的至少部分感光区域3141处于封闭空间中，防止灰尘等杂物附着或落在传感器的感光区域3141中，保证成效效果。在另一实施例中，也可以使用玻璃板，将玻璃板设置在第一棱镜组312a和第一传感器314a之间；或/和玻璃板设置在第二棱镜组312b和第二传感器314b之间。在另一实施例中，也可以使用其他高分子透明板，如塑料板等。
如图2所示，在一实施例中，传输部70包括信号放大电路33，信号放大电路33用于放大获取到的第一电信号和/或第二电信号，并传输至图像信号处理组件41中，防止图像信号在传输过程中过分衰减，而导致图像信号处理组件41接收到的电信号强度过弱，影响成像质量。
