医用红外线成像来源于军工技术， 使用已有 40多年的历史， 随着医学、红外线成像、 及多媒体等多种技术的发展， 红外线成像的温度分辨率已经达到 0. 05度， 空间分辨能力 已经达到 0. 8mrad， 图像清晰度有了很大的提高， 结果分析直观方便， 其在临床上的应用 范围正在扩大。 目前红外线成像诊断在以下方面显示出一定优势： 1， 判断急、慢性炎症 的部位、 范围、 程度； 2， 监测血管性病变的供血功能状态； 3， 肿瘤预警指示、 全程监视 及疗效评估。 由此可见， 红外线成像时对 B超、 CT、 MR等其他形态学诊断方法的重要补 充。
电子胃镜是硬质工作端部前端装置有电子 CCD处理芯片的软质纤维胃镜，电子胃镜是 进行消化道手术的常用器械， 电子胃镜连接有摄像主机、监视器和冷光源主机， 配合各种 各样的手术器械， 医生可以深入胃部内， 进行消化道手术。
目前尚没有出现将红外线热扫描探头结合电子胃镜两者结合进行使用的内窥镜系统。 因此，设计一种将红外线热扫描技术与电子胃镜结合使用的具有红外线热扫描功能的电子 胃镜系统技术迫在眉睫。 发明内容
本发明的目的是克服现有技术的不足，提供一种具有红外线热扫描功能的电子胃镜系 统，该电子胃镜系统是将红外线热扫描系统引进电子胃镜系统中，通过红外线热扫描系统 的探头对胃及其组织进行立体的扫描，多平面连续横切扫描得到的数据传输至红外线热扫 描系统主机进行图像处理，清晰显示胃壁立体血管静态图像，为医生提供一幅胃部及其组 织的红外线热扫描图像， 丰富胃病的诊断手段， 提高诊断的准确性。
为了实现上述技术目的， 本发明是通过以下技术方案来实现的：
本发明所述的具有红外线热扫描功能的电子胃镜系统，包括电子胃镜及与电子胃镜连 接的冷光源主机、摄像主机、 内镜监视器， 所述电子胃镜上还设有红外线热扫描系统， 所 述红外线热扫描系统包括红外线热扫描探头、红外线热扫描处理系统主机和红外线热扫描 系统监视器。
本发明中， 所述电子胃镜采用 CCD电子光学系统， 该电子胃镜包括软质内镜端部、器 械通道、操作手柄和数据接头。该种形式的电子 CCD光学系统， 是安装在软质内镜端部的 先端部，采用直径大于等于 3. Omm光学镜头的 CCD光学系统，且所采用的 CCD芯片采用 1/4" ，至少 48万有效像素的 CCD，镜头视场角 100 ° 或以上。所述软质内镜端部是使用软 性材料制造而成的， 且其先端部具有弯曲的功能。 所述器械通道直径大于等于 3. Omm。
在本发明中， 所述红外线热扫描探头包括探头工作端部、操作手把和数据线， 所述探 头工作端部穿过电子胃镜的器械通道并从软质内镜端部的前端伸出，所述数据线通过接头 与红外线热扫描处理系统主机连接，所述红外线热扫描系统监视器与红外线热扫描处理系 统主机连接。
本发明所述的红外线热扫描探头， 其探头工作端部长度范围为 500〜2000mm， 该探头 工作端部的外径小于等于 3. 0mm,所述探头工作端部前端的探头先端部长度小于 50mm，所 述探头先端部里设计有红外区， 红外区装有红外装置， 红外装置包括红外光源发射器， 红 外接收镜头；红外光源发射器和红外接收镜头组成一组红外装置，探头先端部的红外区里 面集成有三组相同的红外装置， 三组红外装置互成 60度设计； 红外区可以受电机的驱动 旋转， 并做线性和环形的移动， 从而对被扫描体做线性和环形的扫描。
本发明所述的红外线热扫描探头的操作手把， 其结构包括控制开关， 模式选择开关， 微调开关等。 所述的数据线通过接头与红外线热处理系统主机连接。

本发明所述的红外线热处理系统主机，其后面板的输出端口外接操作键盘或手持操作 设备、红外线热扫描系统监视器等，红外线热扫描系统监视器的扫描与红外线热扫描探头 扫描相一致， 实现同步扫描。
本发明所述的红外线热扫描系统， 其工作原理： 胃部组织内血管的血流， 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， 胃部及其周边组织自身的温度不但受到血管内血流的影响， 也受自身的新陈代谢的影响， 所以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的活跃程度的不同而 表现出差异性， 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，红外线热扫 描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胃 部中作近距离进行扫描， 得到精细精确的红外图像。
本发明所述的红外线热扫描系统，其工作过程：胃部血管中血流及组织辐射的红外线， 通过进入胃部内的红外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。多平面连续横切扫描得到的数据传输至红外线热扫描系统主机进行图像处理，输出 到红外线系统监视器， 清晰显示胃壁立体血管静态图像， 医生可通过图像进行分析， 可以 发现胃壁或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。
本发明所述的具有红外线热扫描功能的电子胃镜系统，其临床手术方法如下所述： 首 先为病人作术前的准备工作，然后将电子胃镜的软质内镜端部从病人口腔内导入，缓慢进 入食管至胃部， 电子胃镜的 ccd光学系统及冷光源为医生提供清晰的胃部观察图像， 医生 可以利用电子胃镜做常规的胃部检查和手术;红外线热扫描探头的探头工作端部经电子胃 镜的器械通道进入胃部，启动红外线热扫描功能，在监视器中输出胃壁及周边组织的红外 线图像， 为医生对胃壁及周边组织的病症作出诊断提供依据。
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高， 而且已经逐渐广泛应用在很多领 域， 特别是医疗领域。本发明所述的具有红外线热扫描功能的电子胃镜， 以电子胃镜为平 台， 引入红外线热扫描探头进入胃部内， 利用红外线热扫描探头做线性和环形的移动， 对 胃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线性和环形的扫描监测，以得 到多平面连续横切扫描成像，然后将多平面连续横切扫描得到的数据传输至红外线热扫描 系统主机进行图像处理，清晰显示胃立体血管静态图像，为医生判断胃病变及功能状态提 供可靠的客观依据。此外， 本发明红外线热扫描处理系统提供多种工作模式， 包括普通显 示模式和夜视显示模式， 医生可以通过分析和比较不同显示模式的诊断图像，做出正确诊 断。 本发明极大地丰富胃病的诊断手段， 有效地提高诊断的准确性。 附图说明

图 7为本发明所述的具有红外线热扫描功能的电子胃镜系统的临床手术示意图。其临 床手术方法如下所述： 首先为病人作术前的准备工作，然后把电子胃镜 1的软质内镜端部 11从病人口腔内导入，缓慢进入食管至胃部 9， 电子胃镜 1的 ccd光学系统及冷光源为医 生提供清晰的胃部 9观察图像， 医生可以利用电子胃镜 1做常规的胃部 9检查和手术；红 外线热扫描探头 2的探头工作端部 21经电子胃镜 1的器械通道 12进入胃部 9，启动红外 线热扫描功能，在红外线热扫描系统监视器 7中输出胃壁及周边组织的红外线图像，为医 生对胃壁及周边组织的病症作出诊断提供依据。
如图 1所示本发明做所述的红外线处理主机 5，其操作面板和操作键盘或手持操作设 备 6提供丰富的控制按钮， 开关、 模式选择、 红外强度微调、 监视器菜单等按钮。 模式选 择可以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 3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。
