具有红外线热扫描功能的胆囊镜系统 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带红外线热扫描探头的 胆囊镜系统。 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。
胆囊镜是进行硬镜微创保胆取石手术的核心器械，胆囊镜连接有摄像主机、监视器和 冷光源主机， 配合各种各样的手术器械， 医生可以深入胆囊腔内， 能将胆囊结石和胆囊息 肉取得干干净净。
目前尚没有出现将红外线热扫描探头结合胆囊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胆囊镜结合使用的具有红外热扫描功能的胆囊镜系统 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， 提供一种具有红外热扫描功能的胆囊镜系统， 该胆囊镜系统将红外线热扫描探头及系统引进胆囊镜系统中，通过红外线热扫描探头对胆 囊壁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， 清晰显示胆囊壁的立体血管静态图像， 使得医生根据获得的显示图像， 通 过分析胆囊的红外热扫描图像， 了解胆囊的功能， 得到意想不到的诊断效果。
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胆囊镜系统，包括硬质胆囊镜及与硬质胆囊镜 连接的冷光源主机、摄像主机、内镜监视器，所述硬质胆囊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。
在本发明中， 所述硬质胆囊镜按其使用的光学系统分成以下三种形式：
第一种形式是：所述硬质胆囊镜为采用电子 ccd光学系统的胆囊镜，其包括结硬质内 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， 所述 直线型器械通道的直径大于等于 3. 0mm, 进水通道和出水通道的直径大于等于 1. 0mm。
第二种形式是:所述硬质胆囊镜为采用棱镜光学系统的胆囊镜，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， 所述直线型 器械通道的直径大于等于 3. 0mm, 进水通道和出水通道的直径大于等于 1. 0mm。
第三种形式是： 所述硬质胆囊镜为采用单纯用于诊断的电子 ccd光学系统的胆囊镜， 其包括结硬质内镜端部、冷光源接头、数据接头、 至少一条直线型器械通道， 所述直线型 器械通道的直径大于等于 3. 0mm。
本发明所述的硬质胆囊镜，上述三种形式的硬质胆囊镜的硬质内镜端部为硬质材料所 制造， 具有不可弯曲性， 且其直径小于等于 10mm， 硬质内镜端部长 250〜300mm， 先端部 为了避免损伤粘膜组织的需要， 需要把先端部设计成钝型。
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 头工作端部穿过胆囊镜主体部分的直线型器械通道并从硬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，所述红外线系统监视器与红外线热扫描 处理系统主机连接。
所述探头工作端部的前端为探头先端部， 所述探头工作端部长 500〜2000讓， 所述探 头先端部长度小于 50mm，所述探头工作端部外径小于等于 3. 0mm。所述探头先端部里设有 红外区，红外区里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。 具体来说， 所述红外区的红外装置为三组， 该三组红外装置互成 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； 其操作手把结构包括控制开关， 模式选择开关， 微调开关等。
所述红外线热扫描处理系统主机还包括与其连接的操作面板、操作键盘或手持操作设 备，所述操作面板、操作键盘或手持操作设备上设有控制按钮，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。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， 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： 胆囊壁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，， 胆囊壁组织自身的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， 所以胆囊壁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，对于胆囊壁间的炎症病变等由于其新陈代谢活 跃， 其温度明显高于正常。 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胆囊腔内近距离进行扫描， 得到精 细精确的红外图像。
本发明所述的红外线热扫描系统，其工作过程：血管中血流及胆囊壁组织辐射的红外 线， 通过进入胆囊腔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， 清晰显示胆囊立体血管静态图像， 医生可通过图像进行 分析，可以发现胆囊壁内血管异常丰富、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。
本发明所述的带红外线热扫描探头的胆囊镜系统，其临床手术方法如下所述： 患者消 毒铺巾后， 医生在患者腹壁做切口并通入穿剌器， 经穿剌器通入腹腔镜并做气腹， 在腹腔 镜的直视下提取胆囊至体外， 在胆囊底部做微小切口， 使得硬质胆囊镜进入胆囊腔内， 抽 取胆汁保存并利用进水通道通入生理盐水使得胆囊充盈， 监视器输出胆囊腔内的清晰图 像， 通过器械通道、进水通道和出水通道进入各种器械， 可以进行胆囊腔内手术， 处理结 石息肉等病症； 需要观察胆囊壁间的血管红外状态图， 以诊断胆囊是否存在潜在病变或评 估胆囊的功能状况，则从器械通道通入红外线热扫描探头的工作端部进入胆囊腔内，在腔 内进行红外热扫描， 输出精确的红外热扫描图像， 帮助医生进行诊断。
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。 带红外线热扫描探头的胆囊镜， 以胆囊镜为平台， 引入红外线热扫 描探头进入胆囊腔内，利用红外线热扫描探头做线性和环形的移动，对胆囊壁血管血液运 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，清晰显示胆囊立体血管静态图像，为医生判断胆囊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 极大地丰富胆囊病的诊断手段， 有效地提高诊断的准确性。 附图说明
