Description

一种眼科裂隙灯辅助照明装置 技术领域
本发明涉及医疗设备技术领域，更具体地说，它涉及一种眼科裂隙灯辅助照明装置。
背景技术
眼睛是人类感官中最重要的器官，大脑中大约有80％的知识都是通过眼睛获取的。读书认字、看图赏画、看人物、欣赏美景等都要用到眼睛。裂隙灯显微镜，是眼科检查必不可是少的重要仪器，也是眼科常规检查的用途第一广泛的基础仪器，眼科诊疗及眼科保健、验光配镜等行业国家要求强制配置裂隙灯。
在全世界，从最小的五官科门诊到大的眼科医院再到顶级的眼科疾病研究机构，眼科裂隙灯显微镜都是检查眼睑、结膜、巩膜、角膜、前房、虹膜、瞳孔、晶状体及前1/3玻璃体，确定病变的位置、性质、大小及其深度的最专业的设备。
眼科裂隙灯显微镜大量的被医疗机构、眼科保健机构、眼镜连锁商店使用，仪器上的功能扩展和改进对于人类眼健康有重要的作用。
裂隙灯的构造主要由四部分构成：裂隙照明机构、显微镜光学体、移动平台机构、腮托机构。
现阶段裂隙灯有辅助照明机构，安装在裂隙灯下列部位上：
1.辅助照明机构安装在裂隙照明机构反光镜周围，例如安装在裂隙照明机构反光镜的上部，发出的光经过发射镜照射到眼睛表面上，又例如安装在裂隙照明机构反光镜的下部，发出的光直接倾斜照射到眼睛表面上；
2.辅助照明机构安装在裂隙照明机构左右旋转轴孔内，发出的光直接倾斜照射到眼睛表面上。
这些辅助照明装置都存在以下不足：
1.安装在裂隙照明机构上，使用时要进行裂隙照明机构左右调节，使辅助照明光线照射到需要的部位，使用不方便，例如左右移动了光学体， 就要左右移动照明机构，让光线能均匀的照射到检查部位。
2.光线不管是通过反射镜反射照射还是直接照射都是从一个方向照射(相当于一个点光源照射)，光线容易被前方的物体遮挡，造成照明不均匀，例如眼睫毛的遮挡。
3.裂隙灯还需要更多的不同波长的辅助光线照明，需要增加位置。
发明内容
针对现有技术存在的不足，本发明的目的在于提供一种眼科裂隙灯辅助照明装置，在裂隙灯上增加了一个辅助照明装置，它随着裂隙灯光学体移动，可以解决辅助照明的多角度照射问题。
本发明的上述技术目的是通过以下技术方案得以实现的：
一种眼科裂隙灯辅助照明装置，包括物镜座、支架和照明灯，在所述物镜座上设置有所述支架，在所述支架上设置有所述照明灯；
优选地，两个所述支架分别设置在所述物镜座的端面的两侧，裂隙灯大物镜筒位于两个所述支架之间，在每个所述支架上设置有照明灯。
优选地，所述照明灯为LED灯。
优选地，所述照明灯的走线隐藏在所述物镜座内部。
综上所述，本发明具有以下有益效果：
1)、结构简单，便于实现，灯线也便于隐藏在机体内部。
2)、辅助照明装置设置在观察光学体显微镜的两边，照射的角度更多、部位更广，同时还能随着光学体左右转动而随动。
3)、增加了新的部位设置辅助照明装置，保留了原有部位的辅助照明功能。
