Description

一种高精度的光学相干断层成像探头
技术领域
本发明属于医疗设备领域，尤其涉及一种高精度的光学相干断层成像探头。
背景技术
光学相干断层成像技术(optical coherence tomography，OCT)是新一代的内窥影像学技术。它是基于高等光子学和光纤维技术设计而成的。它利用近红外光来探查血管内微米级结构，有极高的分辨率（10μm），远高于任何现有的成像技术，能够充分满足临床需求。在医学领域，OCT已广泛用于眼科检查及冠心病的诊断与治疗。在心血管领域，OCT探头可直接介入冠状动脉，使用能量束在血管内进行360度周向扫描，获得血管横断面图像。高分辨率使光相干层析成像能更好地分清脂质核心和内膜面，从而能测量纤维帽的厚度，观察脂质核心的大小，斑块表层的糜烂和血小板、巨噬细胞聚集或纤维蛋白沉积，斑块帽裂隙等。而在眼科领域，目前主要进行的是非接触式、非侵入式断层成像，可观察眼前节，又能显示眼后节的形态结构。眼底可清晰地显示黄斑和视乳头的形态特征、视网膜的层间结构、视网膜及其神经纤维层正常厚度变化，另外还可以观察角膜、虹膜、晶状体等眼前段组织，并准确测量相关数据。
而现有的探头结构未采用保护结构，或者是采用了简单的保护结构，使得探头中的转折透镜获取光线的精度较低，影响了成像精度。
发明内容
针对以上现有存在的问题，本发明提供一种高精度的光学相干断层成像探头，采用套筒状的保护套与圆板状的密封罩有机结合，能够有效地保证探头中的转折透镜获取光线的精度，提高了成像精度。
本发明的技术方案在于：
本发明提供一种高精度的光学相干断层成像探头，包括单模光纤、自聚焦光纤、转折透镜、保护套、密封罩、内嵌环和扭矩线缆，所述单模光纤、自聚焦光纤和转折透镜从左向右依次相连，所述保护套包覆在所述单模光纤、自聚焦光纤和转折透镜上且其与包覆在所述单模光纤左端的所述扭矩线缆相连，其特征在于：玻璃制成的所述密封罩呈圆板状且其左端有所述内嵌环，所述密封罩通过所述内嵌环安装在所述保护套的右端，所述内嵌环的左端内径存在倒角且其轴向长度为0.1～0.2mm。
进一步地，所述转折透镜采用玻璃透镜制成。
进一步地，所述密封罩的直径小于或等于所述保护套的外径。
进一步地，所述保护套采用PET材料制成。
本发明由于采用了上述技术，使之与现有技术相比具体的积极有益效果为：
1、本发明采用套筒状的保护套与圆板状的密封罩有机结合，能够有效地保证探头中的转折透镜获取光线的精度，提高了成像精度。
2、本发明所用的密封罩由于有内嵌环的存在，极大提高了密封保护效果。
3、本发明使用便捷，便于推广。
4、 本发明结构简单，安全可靠，具有良好的市场前景。
5、 本发明产品性能好，使用寿命长。
附图说明
图1是本发明的结构示意图。
图中：1-单模光纤，2-自聚焦光纤，3-转折透镜，4-保护套，5-密封罩，6-内嵌环，7-扭矩线缆。
具体实施方式
下面结合附图和实施例对本发明作进一步说明，本发明的实施方式包括但不限于下列实施例。
实施例：为了实现上述目的，本发明采用的技术方案如下：
如图1所示，本发明提供一种高精度的光学相干断层成像探头，包括单模光纤1、自聚焦光纤2、转折透镜3、保护套4、密封罩5、内嵌环6和扭矩线缆7，单模光纤1、自聚焦光纤2和转折透镜3从左向右依次相连，保护套4包覆在单模光纤1、自聚焦光纤2和转折透镜3上且其与包覆在单模光纤1左端的扭矩线缆7相连，玻璃制成的密封罩5呈圆板状且其左端有内嵌环6，密封罩5通过内嵌环6安装在保护套4的右端，内嵌环6的左端内径存在倒角且其轴向长度为0.1～0.2mm。
本发明进一步设置为：转折透镜3采用玻璃透镜制成。
本发明进一步设置为：密封罩5的直径小于或等于保护套4的外径。
本发明进一步设置为：保护套4采用PET材料制成。
通过采用上述技术方案，密封罩5通过内嵌环6安装在保护套4的右端，使得转折透镜3在获得保护套4和密封罩5的密封保护的同时，获得良好的光线，大大提高了探头的精度。
以上对本发明的一个实施例进行了详细说明，但所述内容仅为本发明的较佳实施例，不能被认为用于限定本发明的实施范围。凡依本发明申请范围所作的均等变化与改进等，均应仍归属于本发明的专利涵盖范围之内。
