Description

[根据细则26改正25.01.2019]　一种可切换摄影信号的多通道微创装置 技术领域
本实用新型涉及手术器材设备领域，尤其涉及一种可切换摄像信号的多通道微创装置。
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。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，且光学通道与器械通道在同一工作通道内，观察器械操作时存在死角，器械操作也存在一定的局限性。
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，可对内窥镜工作时进行多角度观察摄像，并有效扩展器械的操作范围。
为了实现上述目的，本实用新型提供如下技术方案：
一种可切换摄像信号的多通道微创装置，包括摄像机与内窥镜；
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。
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。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。
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。
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、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。

为了使本领域的技术人员更好地理解本实用新型的技术方案，下面将结合附图对本实用新型作进一步的详细介绍。
实施例一
如图1-图6所示，本实用新型实施例提供的一种可切换摄像信号的多通道微创装置，包括摄像机与内窥镜；内窥镜包括工作通道1、副窥镜2与主窥镜3。工作通道1包括一体化设置的主通道11、副通道12与手柄13，主通道11与副通道12通过手柄13连接，且主通道11与副通道12的入口均设置在手柄13处。主通道11远离手柄13的一端设置主通道出口14与窥镜视野孔15，副通道12也设置副通道出口16。窥镜视野孔15设置在主通道出口14一侧，位于主通道出口14与副通道出口16之间。主通道11与副通道12之间为锐角，两者入口分离，出口贴紧，即副通道出口16紧贴主通道11。主通道11长度大于副通道12长度。
主通道11与副通道12之间还通过加强筋17连接。
主窥镜3为传统窥镜结构，内部设置主清洗通道31、主光学通道32与主器械通道33。副窥镜2内设置副清洗通道21与副光学通道22，不设置器械通道。主窥镜3设置于主通道11内，主窥镜3设置主目镜罩接口34，副窥镜2设置于副通道12内，副窥镜2设置副目镜罩接口23。
摄像机包括切换装置与2个摄像头，切换装置连接2个摄像头：主摄像头与副摄像头，主摄像头通过主目镜罩接口34连接到主光学通道32，副摄像头通过副目镜罩接口23连接到副光学通道22。切换装置可切换不同摄像视频信号输入，方便使用者观察。
本实用新型工作原理如下：
工作时，将主窥镜3与副窥镜2分别放置在主通道11与副通道12中，将主目镜罩接口34与副目镜罩接口23连接到主摄像头与副摄像头。内窥镜用于手术操作，主窥镜3与副窥镜2均具有光学通道，通过切换装置切换不同的信号输入。
实施例二
如图7所示，本实施例中，窥镜视野孔15与主通道出口14一体化设置，可进一步增加器械的活动范围，方便副窥镜2对其进行观察。本实施例其它部分与实施例一基本相同。
以上只通过说明的方式描述了本实用新型的某些示范性实施例，毋庸置疑，对于本领域的普通技术人员，在不偏离本实用新型的精神和范围的情况下，可以用各种不同的方式对所描述的实施例进行修正。因此，上述附图和描述在本质上是说明性的，不应理解为对本实用新型权利要求保护范围的限制。
