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带红外线热扫描探头的 肛肠镜系统。 现有技术
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。

在本发明中，所述的硬质肛肠镜，根据其采用的光学系统及是否带有进水通道和出水 通道， 可以分为以下三种形式：
第一种形式：所述硬质肛肠镜为采用电子 ccd光学系统的肛肠镜，其包括硬质内镜端 部、 冷光源接头、 数据接头、 至少一条直线型器械通道、 进水通道及出水通道。
第二种形式：所述硬质肛肠镜为采用电子 ccd光学系统的肛肠镜，所述硬质肛肠镜为 采用电子 ccd光学系统的肛肠镜， 其包括硬质内镜端部、冷光源接头、数据接头、 至少一 条直线型器械通道， 与上述第一种相比， 其不带有进水通道和出水通道。
第二种形式： 所述硬质肛肠镜为采用棱镜光学系统的肛肠镜， 其包括硬质内镜端部、 冷光源接头、 目镜输入端、 至少一条直线型器械通道、 进水通道和出水通道。
在本发明中，上述三种形式的硬质肛肠镜的硬质内镜端部均为硬质材料所制造，具有 不可弯曲性， 直径小于等于 20讓， 硬质内镜端部长 300〜450讓， 此外， 为了避免损伤粘 膜组织的需要，硬质内镜端部的先端部设计成钝型；上述三种形式的肛肠镜的器械通道均 大于等于 3. 0mm,且第一和第三种形式的硬质肛肠镜的进水通道和出水通道的直径均大于 等于 1. 0mm。
本发明所述的硬质肛肠镜，第一和第二种形式的肛肠镜采用的 ccd光学系统装置在工 作端部前端，采用直径大于等于 3. 0mm光学镜头的电子 CCD光学系统，其 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；第三种形式的肛肠镜采用棱 镜光学系统， 其光学镜头大于等于 3. 0mm。

本发明所述的红外线热扫描处理系统主机，其操作面板和操作键盘或手持操作设备提 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。
本发明所述的红外线热扫描处理系统主机，其后面板的输出端口外接操作键盘或手持 操作设备、 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系统， 其工作原理： 肛肠道及周边组织间布满了丰富的血管， 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，， 肛肠道内及周边组织的自身温度不但收到血管内血流的影响， 也受自身的新陈 代谢的影响，所以肛肠道组织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， 一般来说， 如果出现炎症或者肿瘤 等病症， 其温度将变高， 表现在红外线热扫描图像中则是异常。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 肛肠道内近距离进行扫描， 得到精细精确的红外图像。
本发明所述的红外线系统， 其工作过程： 血管中血流及肛肠壁组织辐射的红外线， 通 过进入肛肠道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。 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， 清晰显示肛肠立体血管静态图像， 医生可通过图像进行分析， 可以发现肛肠壁内血管异常丰富、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肛肠镜系统，其临床手术方法如下所述： 医生 首先要求病人取截石位， 消毒铺巾后， 将硬质肛肠镜经由患者肛门进入肛肠道， 硬质肛肠 镜能清晰地观察到肛肠道放大数倍的图像，并能通过器械通道、进水通道和出水通道对肛 肠道的病症做治疗； 需要对肛肠壁及周围组织的病变情况进行诊断，可以经由器械通道引 入红外线热扫描探头的工作端部， 进入肛肠道内进行红外线热扫描， 输出到监视器， 医生 可以根据红外图像做出诊断。
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探头的肛肠镜， 以硬质肛肠镜为平 台， 引入红外线热扫描探头进入肛肠道内， 利用红外线热扫描探头做线性和环形的移动， 对肛肠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，清晰显示肛肠立体血管静态图像，为医生判断肛肠病变及功 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。 本发明极大地丰富肛肠病的诊断手段， 有效地提高诊断的准确性。 附图说明
