一体化红外线热扫描胃镜系统 技术领域
本发明属于医用器械领域，具体涉及具有红外线热扫描功能的一体化红外线热扫描胃 镜系统。 现有技术
医用红外线成像来源于军工技术， 已有 40多年的使用历史， 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， 因而其在临床上的 应用范围正逐渐扩大。 目前， 红外线成像诊断在以下方面显示出一定优势： 1 ) 判断组织 疼痛的部位和性质； 2)判断急、 慢性炎症的部位、 范围和程度； 3 )监测血管性病变的供 血功能状态； 4)肿瘤预警指示、全程监视及疗效评估。 由此可见， 红外线成像是对 B超、 CT、 MR等其它形态学诊断方法的重要补充。
胃镜是进行消化道手术的常用器械， 医生可以将其深入胃部内，进行胃部检查或者手 术治疗。将红外线热扫描探头集成于胃镜之中，治疗的同时进行先进的红外线热扫描诊断 的新技术， 提供不同的显示模式， 为胃部位疾病的诊断提供新的视角和新的手段。 目前尚 没有出现两者结合的一体化内窥镜系统。 发明内容
本发明的目的在于克服现有技术的不足，提供一种一体化红外线热扫描胃镜系统，该 一体化红外线热扫描胃镜系统将红外线热扫描探头集成在胃镜系统中，通过红外线热扫描 探头对胃壁及其周边组织进行立体的扫描，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， 并提供不同的显示模式选择， 使得医生能根据获得的不同的显示图像， 通 过分析胃壁的立体血管静态图像，对于了解胃部组织的功能和病变情况，具有意想不到的 诊断效果。
本发明的目的是通过以下技术方案来实现的：
本发明所述的一体化红外线热扫描胃镜系统，包括红外线热扫描胃镜以及与之连接的 冷光源主机、摄像主机、 内镜监视器和红外线热扫描系统， 所述的红外线热扫描系统包括 红外线热扫描处理系统主机和红外线热扫描系统监视器。
在本发明中， 所述的红外线热扫描胃镜为采用电子 CCD光学系统的软质胃镜， 其上 设有工作端部、数据接头和器械通道； 该数据接头与所述的冷光源主机、摄像主机和红外 线热扫描处理系统主机相连接；该工作端部采用软质材料制造，其直径介乎 8.0mm〜15mm 之间， 能够向四个方向分别作至少 90 ° 的弯曲； 该电子 CCD光学系统设置在该工作端部 的前端， 采用直径 3.0mm的光学镜头， 其 CCD芯片采用尺寸 1/4〃 、 至少 48万有效 像素的 CCD, 镜头视场角在 100 ° 以上； 该器械通道的直径 3.0mm。
在本发明中，所述的红外线热扫描胃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。所述红外线热扫描胃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， 可以伸出胃镜先端部平面 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胃镜系统，其临床手术方法如下： 首先为病人作术 前的准备工作，然后将红外线热扫描胃镜的工作端部从病人口腔内导入，缓慢进入食管至 胃部，红外线热扫描胃镜为医生提供清晰的胃部观察图像， 医生可以利用红外线热扫描胃 镜做常规的胃部检查和手术。启动位于红外线热扫描胃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胃镜先端部若干距离，为胃壁及腔体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， 提供医生诊断胃壁及腔体组织状态的依据。
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 在胃镜上， 利用红外线热扫描探头在微型电机驱动下旋转， 伸出胃镜先端部， 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，清晰地显示胃壁的立体血管静态图 像， 为医生判断胃部病变及功能状态提供可靠的客观依据， 丰富胃部疾病的诊断手段， 有 效地提高诊断的准确性。 附图说明
