在本发明中，所述红外线热扫描食管镜在其工作端部的先端部集成有红外线热扫描探 头、 内镜镜头和导光光纤。 所述红外线热扫描探头的直径 3.0mm， 其内设有红外区， 红 外区的外部设有保护套，红外区内至少安装有一组红外装置，所述红外装置包括红外光源 发射器和红外接收镜头。所述红外线热扫描食管镜内还可以设有微型电机，所述红外线热 扫描探头在微型电机的驱动下， 可以伸出食管镜先端部平面 10mm〜50mm。 优选地， 红 外区内安装有三组相同的红外装置， 该三组红外装置互成 60度设计。 所述红外线热扫描 探头可以在微型电机的驱动下旋转， 从而对被扫描体做环形扫描。
在本发明中，所述红外线热扫描系统还包括有与所述红外线热扫描处理系统主机相连 接的操作面板、操作键盘或手持操作设备，所述的操作面板和手持操作设备上设有控制按 钮， 包括开关按钮、模式选择按钮、 红外强度微调功能按钮和监视器菜单按钮。模式选择 按钮用于切换不同的显示模式，包括普通显示模式和夜视显示模式，普通显示模式是指红 外扫描在内镜冷光源和红外光源的照射下进行的显示模式，夜视显示模式是指没有内镜冷 光源和红外光源的照射下，依靠组织物的自身不同辐射强度来成像， 医生对两种模式下的 图像对比分析，可以得到另外一个角度的更好的诊断效果。所述红外线热扫描处理系统主 机的后面板设有输出端口，所述的红外线热扫描系统监视器、操作键盘或手持操作设备连 接于该输出端口，红外线热扫描系统监视器的扫描与红外线热扫描探头的扫描相一致，实 现同步扫描。
本发明所述的一体化红外线热扫描食管镜系统，其工作原理如下：食管壁及其周边组 织布满了丰富的血管， 动脉血温度较高， 静脉血温度较低， 两者存在某种热交换机制， 两 者都向外辐射不同波长的红外线，食管壁及其周边组织自身的温度不但受到血管内血流的 影响，也受自身新陈代谢的影响，所以食管壁及其周边组织内发生异变的部分的温度会由 于血管丰富与否和新陈代谢活跃程度的不同而表现出差异性， 比如食道癌变或炎症等，对 外辐射的红外线的波长也各不相同。 研究表明， 血液中的成分 （血清、 血浆、 血红蛋白、 白蛋白、 红细胞、 淋巴细胞、 血小板）在光谱中对红外光的吸收最低， 意味着血液除了对 外辐射红外线外， 还对周围组织的红外线的吸收影响很小， 红外线系统的精度小于等于 0.05度， 空间分辨能力至少达到 0.8mrad， 红外线热扫描探头在食管中近距离进行扫描， 得到精细精确的红外图像。
本发明所述的一体化红外线热扫描食管镜系统，其工作过程如下：食管壁及其周边组 织中血管的血流及组织辐射的红外线，经进入食管内的红外线热扫描探头的精密红外探测 器-红外接收镜头接收后， 处理芯片将光信号转换成电信号， 经过预处理（如放大、 滤波 等）， 由前置放大器和主放大器放大到一定电平之后便进入红外线热扫描处理系统主机。 同时输入主机的信号还有同步信号、参照黑体信号等。红外线热扫描探头启动后， 在微型 电机的驱动下伸出食管镜先端部若干距离，并在微型电机的驱动下旋转，对食管壁做环形 扫描， 多平面连续横切扫描得到的数据传输至红外线热扫描处理系统主机进行图像处理， 并输出到红外线热扫描系统监视器， 清晰地显示食管壁及周边组织的立体血管静态图像， 医生通过图像分析，可以发现食管壁及其周边组织血管异常丰富、血管异常稀疏或者存在 血管缺失区域等异常情况， 给医生及时提供即时的诊断依据。
本发明所述的一体化红外线热扫描食管镜系统，其临床手术方法如下： 患者首先做适 当体位， 向患者口腔部放入支撑器并固定， 做好准备工作， 然后向患者食管缓慢插入红外 线热扫描食管镜，红外线热扫描食管镜提供清晰的患者食管的图像，经过红外线热扫描食 管镜的器械通道可以配合处理患者食管的肿瘤等病症。启动位于红外线热扫描食管镜先端 部的红外线热扫描探头，红外线热扫描探头启动后伸出食管镜先端部若干距离，为食道壁 及其周边组织做旋转的红外线热扫描，输出到红外线热扫描系统监视器，提供医生诊断食 道及其周边组织状态的依据。
与现有技术相比，本发明的有益效果是： 目前的医用红外成像技术的红外分辨率的精 度很高， 而且已经逐渐广泛应用在很多领域， 特别是医疗领域。将红外线热扫描探头集成 在食管镜上， 利用红外线热扫描探头在微型电机驱动下旋转， 伸出食管镜先端部， 对食管
壁血管血液运动产生的温度差异而形成的红外线辐射进行扫描监测，多平面连续横切扫描 得到的数据传输至红外线热扫描处理系统主机进行图像处理，清晰地显示食管的立体血管 静态图像，为医生判断食管壁及其周边组织的病变及功能状态提供可靠的客观依据，丰富 食管疾病的诊断手段， 有效地提高诊断的准确性。 附图说明
