Description

一种双路输出冷光源的多通道微创装置 技术领域
本实用新型涉及手术器材设备领域，尤其涉及一种双路输出冷光源的多通道微创装置。
背景技术
由于微创手术具有创伤小、疼痛轻、恢复快的优越性，“微创”这一概念已深入到外科手术的各种领域。微创手术是指利用腹腔镜、胸腔镜等现代医疗器械通过微创通道装置及相关设备进行的手术。
微创技术中会用到椎间孔镜，椎间孔镜包括外部的套管，与设置在套管内的内窥镜。传统的内窥镜中设置清洗通道、光学通道与器械通道，并设置导光纤维。光学通道用于放置摄像头，使操作者可以观察到操作处的情况，器械通道内放置手术器械。内窥镜内还会设置光纤，光纤外接冷光源，用于为摄像头照明，方便操作者观察患者体内的情况。但是传统方案中存在以下不足：
光学通道固定设置在器械通道的一侧，观察器械操作时存在死角。
发明内容
本实用新型的目的是提供一种多通道微创通道用内窥镜，可对内窥镜工作时起到辅助观察的作用。
为了实现上述目的，本实用新型提供如下技术方案：
一种双路输出冷光源的多通道微创装置，包括摄像机、冷光源发生器与内窥镜；
所述内窥镜包括工作通道、主窥镜与副窥镜，所述工作通道包括主通道、副通道与手柄，所述主通道、副通道与手柄刚性连接，主通道与副通道的入口设置在手柄上，所述主通道内设置主窥镜，所述主窥镜内设置主清洗通道、主光学通道与主器械通道，副窥镜设置在副通道内，副窥镜内设置副清洗通道与副光学通道，副窥镜内不设置器械通道；
所述摄像机包括切换装置与2个摄像头，所述2个摄像头分别连接主窥镜与副窥镜，所述切换装置连接2个摄像头。
摄像头切换装置可通过切换信号，使显示器显示不同内窥镜观察的内容，使手术操作者观察更加方便。
副通道内设置了副窥镜，副窥镜可起到观察的功能，能起到辅助效果。切换装置可通过切换信号，使显示器显示不同的内容，使手术操作者观察更加全面。
而冷光源发生器可分别在主窥镜或副窥镜进行摄像操作时，相应的打开主窥镜或副窥镜对应的冷光源输出口，以确保摄像时光线的角度核实，或者两个冷光源输出口均打开，在不提高光纤输出亮度的同时，改善操作处的照明效果。
优选地，所述主通道长度大于副通道。主通道长度更长，避免了副通道内设备对主通道造成影响。
优选地，所述主通道与副通道呈锐角设置，主通道与副通道在出口处贴合，入口处分开。出口处贴合可节约操作空间
优选地，所述主通道出口一侧设置窥镜视野孔，所述窥镜视野孔位于主通道出口与副通道出口之间。窥镜视野孔用于主窥镜与副窥镜的观察。
优选地，所述主通道、副通道与手柄一体化结构，主通道与副通道之间通过加强筋连接。
优选地，所述主通道出口与窥镜视野孔连通。出口与窥镜视野孔连通可扩大观察范围。
优选地，所述主通道直径大于副通道直径。由于副通道内不设置器械，通道副通道直径较小，可节约空间。
优选地，所述主窥镜设置主目镜罩接口，主光学通道与一个摄像头通过主目镜罩接口连接；所述副窥镜设置副目镜罩接口，副光学通道与另一个摄像头通过副目镜罩接口连接。根据实际使用情况，即可将主窥镜或副窥镜单独连接到切换装置，也可同时将主窥镜与副窥镜连接到切换装置。
优选地，所述主窥镜内设置主窥镜光纤，所述主窥镜光纤连接一个冷光源输出口；所述副窥镜内设置副窥镜光纤，所述副窥镜光纤连接另一个冷光源输出口。两个冷光源输出口各对应一组光纤，确保某一摄像头工作时，可切换至对应光纤的光纤进行照明，不影响操作者进行观察。
本实用新型具有以下有益效果：
1、主通道与副通道可分别放入不同的内窥镜，在进行手术操作时，可多角度对操作部位进行观察；
2、传统的椎间孔镜影像显示设备只能固定显示一组图像，而本方案中主窥镜与副窥镜通过不同的视频信号进行影像输入，可根据操作时的实时需要进行切换；
3、不论哪个摄像头处于工作状态，都有对应的光纤通过冷光源发生器进行照明；
4、副窥镜专用于操作中的观察，不设置手术器械，体积更小，节约空间。
