Description

一种内窥镜探头
技术领域
本发明属于医疗器械，具体涉及一种内窥镜探头。
背景技术
目前内窥镜探头通常将光源和小型摄像机集成在探头的最前端面上，光源照射范围小，光线和镜头方向一致成像较为清晰，但是对于侧方向成像在形状和尺寸容易失真，导致诊断出现较大失误。还有一类的探头是镜头在最前端面上、光源在探头侧面形成光圈，但是由于光源照射方向和镜头不在同一方向，成像不清晰。这两类探头对如食道等侧壁易发生病变的器官成像效果差，都对诊断有影响。
发明内容
为了解决上述问题，本发明提供了一种内窥镜探头，侧方成像清晰、不失真。
本发明采用的技术方案如下：
一种内窥镜探头，包括插入管、导向关节和探头，所述导向关节的左端与插入管连接、右端与探头连接，所述探头的前部侧面开设有截面为梯形的坡口，所述坡口的三个面上分别安装有光源、镜头和反光镜，所述镜头的拍摄方向与探头的轴向垂直，所述光源的光线方向与探头的轴向平行，所述反光镜的镜面所在平面与所述光源的安装平面之间呈锐角布置。
上述内窥镜探头，其特征在于：所述反光镜（13）的镜面所在平面与光源（11）的安装平面之间夹角为30-40°。
3、根据权利要求1所述的内窥镜探头，其特征在于：所述坡口的深度为探头（1）直径的1/2-2/3。
4、根据权利要求1所述的内窥镜探头，其特征在于：所述插入管（3）有外层到里层依次包括外聚亚安酯层、外钨丝编制皮、内聚亚安酯层、内钨丝编制皮和钢绞线。
本发明的有益效果为：将光源和镜头设置在探头侧面的坡口中，借助反光镜将光线进一步反射，保证整体空间光照充足的前提下，镜头。
附图说明
图1为本发明的结构示意图；
图中：1为探头、2为导向关节、3为插入管、11为光源、12为镜头、13为反光镜。
具体实施方式
下面结合附图对本发明进一步解释说明。
本发明内窥镜探头，包括插入管3、导向关节2和探头1，所述导向关节2的左端与插入管3连接、右端与探头1连接，所述探头1的前部侧面开设有截面为梯形的坡口，所述坡口的三个面上分别安装有光源11、镜头12和反光镜13，所述镜头12的拍摄方向与探头1的轴向垂直，所述光源11的光线方向与探头1的轴向平行，所述反光镜13的镜面所在平面与所述光源11的安装平面之间呈锐角布置以保证整个探头1的强度。
上述内窥镜探头，所述反光镜13的镜面所在平面与光源11的安装平面之间夹角为30-40°。其中，夹角优选为34-37°，反光镜13对镜头成像干扰小、光线效果较好，既能保证探头1强度足够，也能令患者有舒适的使用体验。
上述内窥镜探头，所述坡口的深度为探头1直径的1/2-2/3。
上述内窥镜探头，所述插入管3有外层到里层依次包括外聚亚安酯层、外钨丝编制皮、内聚亚安酯层、内钨丝编制皮和钢绞线。
