Description

一种多通道微创通道用内窥镜
技术领域
本实用新型涉及手术器材设备领域，尤其涉及一种多通道微创通道用内窥镜。
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：
1.手术器械尺寸不同，尺寸较小的器械强度不足，尺寸较大的器械无法顺利插入器械通道中，只能单独使用；
2.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。
实用新型内容
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：
一种多通道微创通道用内窥镜，包括工作通道与副窥镜，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，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。副通道内设置了副窥镜，副窥镜可起到观察的功能，即可对主通道观察功能起到替代，也能起到辅助效果。
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和副窥镜的观察。
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。主窥镜采用传统结构，副窥镜可起到协助观察的作用。
优选地，所述主通道内设置手术器械。主通道内可放置较大尺寸的手术器械，副窥镜代替原主窥镜的观察与清洗功能。
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。
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椎间孔镜，在进行手术操作时，可多角度对操作部位进行观察；
2、主通道可放入大尺寸器械，可使用更高强度的器械，适应范围更广；
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。
附图说明
为了更清楚地说明本实用新型的技术方案，下面将对描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本实用新型的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图5为实施例一B处放大图；
图6为实施例二B处放大图；
图7为实施例三结构示意图；
附图标记说明：

具体实施方式
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5所示，本实用新型实施例提供的一种多通道微创通道用内窥镜，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，副窥镜2设置于副通道12内。
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，将本装置用于手术操作，主窥镜3与副窥镜2均具有光学通道，可进行切换观察。
实施例二
如图6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。
实施例三
如图7所示，本实施例中，主通道11内不设置主窥镜3，直接放置手术器械4，因此可直接使用尺寸较大的器械，在通道直径不便的情况下增加了通用性。副窥镜2同样可用于清洗与影像观察。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。
