探测部件21可以为图像采集部件，随着图像传感器的迅速发展，现在最小的图像传感器已可以做到0.7*0.7mm，因此急需一种可有效控制外径、带照明、封装安全可靠、成本低廉的封装结构，而本实施例及其可选方案所涉及的装置恰可满足该需求。
若探测部件21为传感器，具体可包括芯片与镜头，该传感器可如图所示形成长方体结构。此外，探测部件21还可具体包括探测部件框架，进而，传感器可设置于该探测部件框架。
为了适于实现图像的有效采集，所述的结构还可利用照明部件6进行照明，其朝向可以与探测部件21相一致。
本实施例中，为了适于照明部件6的安装，两个副柔性板12弯折至所需位置时分别处于所述模组座3的相对的第二侧与第三侧。其中，副柔性板12与主柔性板11可以本身是具有一定柔性的，副柔性板12与主柔性板11之间可以被配置为两者可相对弯折，一种举例中，该弯折可以是适于单向的弯折，也可以是适于双向的弯折。该弯折可例如通过将连接处的厚度设计为较薄的结构形式来实现，另一种举例中，柔性板本身也可实现弯折，故而也可不另外设计适于弯折的结构形式。换言之，副柔性板12可以理解为能够被弯折至模组座3的第二侧或第三侧的柔性电路板的部分，且该部分主要是为了实现照明部件5的安装与定位。
本实施例中，所述副柔性板12的末端设有所述照明部件5，由于副柔 性板12与主柔性板11连接，远离该连接处的一端可理解为其末端，所述副柔性板12的末端向前延伸至靠近所述探测组件2的前端的位置。
通过副柔性板12，可以适于将照明部件5设置于探测部件21的位置，从而有利于对探测方向实施充分且有效的照明，其中，照明部件5与探测部件21可持平，即处于同一参考平面，其可有利于使照明更均匀，该参考平面可理解为垂直于探测方向的平面。

照明导电材料，可以为能够实现导通连接的任意材料，具体为与照明部件5与照明接线部113分别导通的导电材料，进而，能够实现照明电线与照明部件5之间信号和/或电能的传输，照明导电材料，可以为例如铜片的金属片。照明接线部113，可以为能够实现导通焊接的任意材料，具体可以为例如铜片的金属片。
其中一种实施方式中，所述副柔性板12包括连接于所述主柔性板11的第一板体121、连接于所述第一板体121前端的第二板体122，以及连接于所述第二板体122前端的第三板体123，所述照明部件5设于所述第三板体123。
其中，所述第一板体121能够相对所述主柔性板11弯折，所述第二板体122能够相对于所述第一板体121弯折，所述第三板体123能够相对于所述第二板体122弯折；其弯折的实现方式可参照前文有关主柔性板11与副柔性板12之间的弯针理解。
所述第一板体121、所述第二板体122，以及所述第三板体123均弯折至所需位置时，一个副柔性板12的第一板体121与第二板体122连接于所述模组座3的第二侧，另一个副柔性板12的第一板体121与第二板体122连接于所述模组座3的第三侧，所述副柔性板12的第三板体123处于所述模组座3的前端一侧，即第三板体123向前延伸至模组座3外。
其中，在弯折至所需位置时，两个第三板体123相对设置，两个第一板体121也相对设置。进而，其可保障探测组件2两侧对称为探测提供均匀的照明。
其中一种实施方式中，请参考图7，在未弯折时，所述柔性电路板可以呈凹字形结构，其一个表面可设有以上所涉及的探测导电材料111。
在未弯折时，两个第一板体121之间的间距可以与两个第三板体123之间的间距不同，例如，此时第一板体121之间的间距可大于两个第三板体123之间的间距；进而，在弯折后，可有利于第三板体123相对于第一板体121沿垂直于探测方向的方向发生位置偏移，，例如可以使得：在弯折至所需位置后，第一板体121与对应的第三板体123之间沿模组座3的第四侧至第一侧的方向发生偏移，从而有利于使得第三板体123上的照明部件5更接近探测组件2，提供更有针对性地有效地照明。
请参考图1至图4，若所述照明部件5设于所述第三板体123的与另一第三板体123相对的一侧表面，即：在弯折至所需位置时，照明部件5分别设于两个第三板体123的相对的一侧表面，则两个第三板体123间的间距与所述探测组件2的对应方向的尺寸与所述照明部件5的对应方向的尺寸相匹配；该匹配，可理解为：由于探测组件2与照明部件5处于两个第三板体123之间，两个第三板体123间的间距可随着该方向上探测组件2中探测部件21尺寸的变大，和/或照明部件5尺寸的变大而适应性发生变大，同时，该匹配可以是相等的，也可以是不相等的。
图10是本发明一实施例中探测封装结构的结构示意图五。
请参考图10，若所述照明部件5设于所述第三板体123的与另一第三板体123相背的一侧表面，即：在弯折至所需位置时，照明部件5分别设于两个第三板体123的相背的一侧表面，则两个第三板体123间的间距与所述探测组件2的对应方向的尺寸相匹配；该匹配，可理解为：由于探测组件2 处于两个第三板体123之间，照明部件5不处于两个第三板体123之间，则两个第三板体123间的间距可随着该方向上探测组件2中探测部件21尺寸的变大而适应性发生变大，同时，该匹配可以是相等的，也可以是不相等的。
可见，该实施方式中，通过柔性电路板的弯折，可有利于减小封装结构的径向尺寸。具体的，柔性电路板可理解为FPC电路板，其厚度可以只有0.15mm并可折叠，故而，其可以有效控制探测部件与照明部件的径向封装尺寸，减少制作和装配时对尺寸的精度要求，即便在装配时受外力也不易损坏。
本实施例采用了柔性电路板，其在保障导通连接的同时，可便于实现装配，因其具有柔性，不易于因为尺寸的误差或者外力影响而对导通焊接的性能造成影响，进一步提高了导通焊接的稳定性。
请参考图8和图9，并结合图4和图5，所述模组座3的第一侧形成有用于定位安装所述探测组件2的探测定位部31，所述模组座3的与其第一侧相对的第四侧形成有用于供器械管4穿过的器械管通道33，所述模组座3的第二侧与第三侧形成有用于容置至少部分所述副柔性板12的柔性板通道32。
其中的探测定位部31，可以为对外延伸出的两个定位凸起，两个定位凸起之间的间距可以与探测部件21的对应方向的尺寸相匹配，以使得探测部件21能够穿过该两个定位凸起之间的间隙，同时，两个定位凸起之间的间距可以小于探测电路板22的对应方向的尺寸，从而保障探测电路板不会穿过该间隙。可见，通过该探测定位部31，可以实现探测组件2的限位固定。
以上所涉及的器械管通道33的形状可以为任意能够与器械管4相适配的形状，以上所涉及的柔性板通道32，可以为能够适于副柔性板12容置穿过的任意结构形式的通道。
通过以上设计，所述模组座3可形成“H形”的结构，具体可以为金属结构，以图9为例，探测组件2与器械管4分别对称分布于“H形”的上下位置；模组座3的侧面开有柔性板通道32，其具体可以包括形成有底面平面的定位边结构，用于定位柔性电路板1与探测电路板，方便安装、定位准 确、强度高，使探测部件装配好后不会受外力影响，改善探测部件、LED与电缆线的焊接强度、可靠性，降低焊点与外管的短路风险。
此外，该定位凸起的外边缘可以呈圆弧形，其可适于与外套管6相适配。
通过模组座上形成的探测定位部、器械管通道与柔性板通道，还可起到便于安装、提高定位准确度与连接强度的作用，使得装配后的探测部件不易于受外力影响。
具体实施方式中，所述主柔性板11和/或所述副柔性板12与所述模组座3胶固。进而，当电线受到轴向的拉力时，依旧能保障较佳的强度。
其中一种实施方式中，器械管4可以为柔性圆形管状结构，同其它零件装入金属管状外套管后用胶水固定形成内窥镜插入部。所述电缆线可以为带屏蔽层的多芯同轴线。屏蔽层可有效增加焊接强度，也可避免其中的电线发生异常。
本实施例还提供了一种体内探测装置，包括以上可选方案涉及的探测封装结构、柔性的可控弯曲管，所述探测封装结构在所述可控弯曲管的一端形成插入部。
该插入部与可控弯曲管可以为内窥镜的可控弯曲管与插入部。
具体实施过程中，通过以上所涉及的结构与装置及其变形结构，可例如封装出直径2-10mm的微型传感器内窥镜插入部，大大扩展了微型传感器在内窥镜领域的应用范围。
综上所述，本实施例提供的探测封装结构与体内探测装置，通过柔性电路板中的主柔性板与探测组件，避免了电缆线与探测组件的直接焊接，利用主柔性板上的探测导通材料与探测接线部，相较于线与线之间的焊接，其可有利于对焊点的放大，故而，本发明降低了焊接操作的难度，提高了焊接的强度、可靠性，满足多种运动状况下的导通焊接的稳定性。
同时，本发明采用了柔性电路板，其在保障导通连接的同时，可便于实现装配，因其具有柔性，不易于因为尺寸的误差或者外力影响而对导通焊接的性能造成影响，进一步提高了导通焊接的稳定性。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通 技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
