具体实施方式
下面通过具体实施方式结合附图对本发明作进一步详细说明。其中不同实施方式中类似元件采用了相关联的类似的元件标号。在以下的实施方式中，很多细节描述是为了使得本申请能被更好的理解。然而，本领域技术人员可以毫不费力的认识到，其中部分特征在不同情况下是可以省略的，或者可以由其他元件、材料、方法所替代。在某些情况下，本申请相关的一些操作并没有在说明书中显示或者描述，这是为了避免本申请的核心部分被过多的描述所淹没，而对于本领域技术人员而言，详细描述这些相关操作并不是必要的，他们根据说明书中的描述以及本领域的一般技术知识即可完整了解相关操作。
另外，说明书中所描述的特点、操作或者特征可以以任意适当的方式结合形成各种实施方式。同时，方法描述中的各步骤或者动作也可以按照本领域技术人员所能显而易见的方式进行顺序调换或调整。因此，说明书和附图中的各种顺序只是为了清楚描述某一个实施例，并不意味着是必须的顺序，除非另有说明其中某个顺序是必须遵循的。
本文中为部件所编序号本身，例如“第一”、“第二”等，仅用于区分所描述的对象，不具有任何顺序或技术含义。而本申请所说“连接”、“联接”，如无特别说明，均包括直接和间接连接(联接)，本申请所述的“远端”、“近端”应理解为远离内窥镜手柄10端为远端，靠近内窥镜手柄10端为近端。
如图2-3所示，一种内窥镜装置，包括长管4、热源1和相变导热件6；其中长管4为管状结构，内部中空，热源1、相变导热件6设置在长管4内部，相变导热件6与长管4热耦合；相变导热件6的一部分与热源1热耦合，其余部 分以远离热源1的方向沿长管4向延伸。在本实施例中，相变导热件6可以是热管或均热板等其他可以通过相变吸收热量的材料；热源1产生的热量可以从相变导热件6靠近热源1端传导到远离热源端，并且通过相变导热件6和长管4的热耦合关系，热量还可以传导到长管4上，最大程度上避免热量在热源1附近聚集，造成局部温度过高，提高了散热效率。
在一实施例中，相变导热件6沿长管4轴向方向延伸设置，相变导热件6沿长管4轴向方向延伸的长度小于长管4长度的一半，可以减少成本。在一实施例中，相变导热件6沿长管4轴向方向延伸设置，相变导热件6沿长管4轴向方向延伸的长度大于等于长管4长度的一半，增加相变导热件6和长管4的热耦合长度可以进一步提高散热效果。在一实施例中，相变导热件6可以贯通设置在长管4内部，相变导热件6沿长管4轴向方向延伸的长度可以基本同长管4长度一致。
在一实施例中，至少部分相变导热件6外表面直接与长管4内表面接触，热源1产生的热量可以通过相变导热件6直接传导到长管4上。
在一实施例中，至少部分相变导热件6外表面在其外周方向上与产管内表面接触，接触表面形状上相互贴合适配，接触面更大，更适配，使得热传导效率更高。
如图5-图8所示，在一实施例中，还包括支架5，支架5设置在长管4内部，附图描述了支架5两种不同结构形态，但本发明不限于这两种结构形态。
如图5和图7所示，在一实施例中，长管4内部包括内管7，使得长管4内部可以划分为两个区域；在一实施例中，长管4包括第一容纳腔和第二容纳腔，相变导热件6和支架5设置在第一容纳腔内，第二容纳腔用于放置电路板(图中未显示)。在另一实施例中，长管4包括第一容纳腔和第二容纳腔，相变导热件6、支架5和电路板设置第一容纳腔内，第二容纳腔用于放置光纤3。
在一实施例中，至少部分支架5表面直接与长管4内表面接触，用以通过支架5将热量传导到长管4上。
在一实施例中，至少部分支架5表面和长管4内表面在其内周方向上接触，接触表面形状上相互贴合适配，接触表面形状上相互贴合适配，接触面更大，更适配，使得热传导效率更高。
如图4所示，在一实施例中，还包括导热材料13，导热材料13填充在相变 导热件6外表面和长管4内表面之间，和/或导热材料13设置在支架5表面和长管4内表面之间，导热材料13可以是导热胶、导热硅脂等。
在一实施例中，支架5包括至少两个支架单件，支架单件沿相变导热件6轴向分布，多个支架单件设置在不同的位置，可以为相变导热件6提供多点支撑，也可以满足多热源1散热的场景。支架5单件可以在内窥镜远端和近端分别设置，也可以设置在长管4中间位置。在一实施例中，支架5单件可以固定在某一位置或可相对长管4滑动。
如图4所示，在一实施例中，还包括热耦合元件2，相变导热件6或/和支架5通过热耦合元件2与热源1热耦合，通过热耦合元件2将热源1产生的热量传递到相变导热件6或/和支架5上，再通过相变导热件6或/和支架5与长管4热耦合关系，实现将热量导向长管4。
在一实施例中，热耦合元件2设置有凹槽结构，相变导热件6或/和支架5的一部分设置在凹槽结构中。在一实施例中，凹槽结构的形状和相变导热件6或/和支架5接触部分的形状相互贴合适配，可以扩大接触面积，提高散热效率。在另一实施例中，凹槽结构和相变导热件6或/和支架5接触部分的缝隙填充有导热材料13，一方面可以固定相变导热件6或/和支架5，提高稳定性，另一方面可以进一步提高散热效率。在另一实施例中，不仅热耦合元件2的凹槽结构和相变导热件6或/和支架5之间可以填充导热材料13，热耦合元件2其他部分和相变导热件6或/和支架5之间也可以填充有导热材料13，用于提高散热效率。
在一实施例中，热源1包括至少两个，沿长管4轴向方向分别设置在长管4内部不同位置。在一个内窥镜中可能存在多个热源1，如电子内窥镜远端有摄像模组，近端可能设置有信号处理组件等发热元件，而本发明披露的方案可以适用于多个热源1场景下，便于散热，避免热量聚集，造成元件损坏或影响精度。
在一实施例中，如图9和图10所示，一种内窥镜装置，包括长管4、热源1、相变导热件6和隔热件8；其中长管4为管状结构，且内部中空，热源1、相变导热件6和隔热件8设置在长管4内部；热源1在内窥镜装置使用过程中会产生热量；相变导热件6沿长管4轴向方向延伸设置，且相变导热件6与热源1和长管4热耦合，用以将热源1产生的热量通过相变导热件6传导至长管4上，在本实施例中，相变导热件6可以是热管或均热板等其他可以通过相变吸收热量的材料；热源1产生的热量可以从相变导热件6靠近热源1端传导到远 离热源1端，并且通过相变导热件6和长管4的热耦合关系，热量还可以传导到长管4上，最大程度上避免热量在热源1附近聚集，造成局部温度过高，提高了散热效率；隔热件8设置在相变导热件6外表面和长管4内表面之间，隔热件8用于阻隔相变导热件6的热量传导到长管4上，因为长管4远端部分会插入患者体内，所以长管4远端部分并不适合用于散热，所以隔热件8沿长管4轴向方向延伸设置，且延伸长度大于长管4长度的一半。在另一实施例中，隔热件8可以为多个隔热单件，多个隔热单件的总长度要大于长管4长度的一半；在另一实施例中，多个隔热单件，隔热单件沿着相变导热件6轴向方向延伸。在一实施例中，其中，至少有一个隔热单件设置在长管4远端，需插入人体部分，用于阻隔热源1产生的热量传导至长管4远端，损害患者身体。
在另一实施例中，还包括导热材料13，导热材料13填充在未设置隔热件8的相变导热件6外表面和长管4内表面之间。可以提高导热效率。
在一实施例中，隔热件8沿相变导热件6的外周方向围绕相变导热件6设置。在一实施例中，隔热件8沿相变导热件6外周方向上全封闭围绕设置。
在一实施例中，长管4内部包括内管，使得长管4内部可以划分为两个区域；在一实施例中，长管4包括第一容纳腔和第二容纳腔，相变导热件6和支架5设置在第一容纳腔内，第二容纳腔用于放置电路板。在另一实施例中，长管4包括第一容纳腔和第二容纳腔，相变导热件6、隔热件8、支架5和电路板设置第一容纳腔内，第二容纳腔用于放置光纤3。
热耦合元件2设置有凹槽结构，相变导热件6至少一部分设置在凹槽结构中。在一实施例中，凹槽结构的形状和相变导热件6接触部分的形状相互贴合适配，可以扩大接触面积，提高散热效率。在另一实施例中，凹槽结构设置有倒角，以便安装时将相变导热件6导入凹槽结构中。

摄像主机600通过通信线缆810与摄像头500连接，摄像头500获得的图像信号通过通信线缆810传输到摄像主机600进行处理。在某些实施例中，通信线缆810可以为纯电通信线缆、纯光通信线缆或光电复合通信线缆。当通信线缆810包括光通信线缆时，例如光纤；摄像头500将图像信号(电信号)转 成光信号，由通信线缆810传输到摄像主机600，摄像主机600再将光信号转成电信号。或者在另一实施例中，通信线缆810与摄像主机600通过电信号接口连接，通信线缆810在与摄像主机600连接的一端先将光信号转成电信号，再通过电连接器将电信号传输至摄像主机600。摄像主机600通过视频连接线820与显示器700连接，用于将视频信号发送到显示器700进行显示。又例如，在其他实施例中，摄像头500与摄像主机600为无线信号传输，而非通过通信线缆810进行通信连接。
本领技术人员应当理解的是，图1仅是内窥镜摄像系统10000的示例，并不构成对内窥镜摄像系统10000的限定，内窥镜摄像系统10000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。例如，内窥镜摄像系统10000还可以包括扩张器、烟雾控制装置、输入输出设备、网络接入设备等。又例如，图1示出的硬管内窥镜300和摄像头500为光学硬管镜，图像传感器设置于摄像头500内；在其他实施例中，硬管内窥镜300和摄像头500可以为集成式的电子内窥镜(例如3D电子内窥镜)，其图像传感器设置于硬管内窥镜300的头端。
光源100用于向待观察部位1000提供照明光源。所述照明光源包括可见光照明光源和对应于荧光试剂的激光照明光源(例如近红外激励光)。
