Description

一种内窥镜用管及内窥镜 技术领域
本发明涉及医疗器械设备领域，尤其涉及一种内窥镜用管及内窥镜。
背景技术
内窥镜是一种应用非常广泛的医疗器械，通常内窥镜包括插入管及操作部。插入管用于进入人体，插入部的前端设有弯曲部，弯曲部用于引导插入部运动。操作部位于人体外控制弯曲部在人体内运动。使用时将内窥镜的插入管经人体的天然孔道，或者是经手术做的小切口进入人体内，导入预检查的器官内，可直接窥视有关部位的变化。
插入管中设置有容纳检测和诊疗的医用器械的内管道，但是在进行激光治疗时会产生热量、气体、切除的废物等，这些废物都会遮挡内窥镜镜头造成视野模糊，而激光光纤在内管道中就不能再连接冲洗管进行注液冲洗，镜头很容易模糊，所以需要在内窥镜中多设置一个用于输送气液的子通道。
额外的通道占用插入管内的空间，当内管道尺寸一定时，增加额外的通道会导致插入管外径增加，但是由于人体某些区域自然通道比较狭窄，插入管直径可能超出自然通道，因此需要通过手术手段进行扩张，此时病人需要麻醉，麻醉时间长、危害大、副作用大且费用高。
发明内容
为了克服至少一个上述现有技术的技术问题，本发明提供了一种 增加了子通道，同时还能保证内管道直径大，插入管外径小的内窥镜用管及内窥镜。
提供了一种内窥镜用管，包括插入管，所述插入管内设置有至少一个中空的内管道，所述内管道与插入管之间留有空隙，内管道外壁与插入管内壁环绕形成的中空腔道设为外通道，所述外通道设置有至少一个具有输送功能的子通道。
上述的一种内窥镜用管至少具有以下的有益效果：将插入管的内腔尽可能扩大，可以使得内管道的直径也变大，能方便器械通入；然后充分利用插入管与内管道间的空隙，在不增加额外管道的基础上增加了至少一个通道，能增加使用功能还不会增大插入管直径。
在上述多通道可弯曲管道的一些实施例中，所述内管道的部分管壁与插入管的管壁重合。内管道由内管道本体和插入管围绕而成，内管道的管壁包括内管道本体和部分插入管，不规则的内管道周长能利用插入管的边角部位，能增大内管道的周长。
在上述多通道可弯曲管道的一些实施例中，所述内管道与插入管为独立管道，内管道与插入管均为中空管道，所述内管道固定在所述插入管内。内管道为单独的空心管道，安装时将内管道穿入插入管内，利用连接件或粘合剂将内管道固定在插入管内，插入管和内管道加工比较简单，生产比较方便。
在上述多通道可弯曲管道的一些实施例中，所述外通道内设置有至少一个隔板，将所述外通道分隔成至少两个通道，其中至少有一个通道为子通道。多个通道能起到不同功能，例如同时进行输液和抽吸， 而且不会额外增加管道，不会增大插入管直径。
提供了一种内窥镜，包括上述任一所述的内窥镜用管，握持部件固定在插入管上；摄像组件设置在外通道内或插入管外。
上述的一种内窥镜至少具有以下的有益效果：在不增加额外管道的基础上增加了至少一个通道，能实现气液输送或固液抽吸等不同功能，使得内窥镜的功能更加丰富；并且还不会增大插入管直径，同时保证了内窥镜使用时的安全性。
在上述内窥镜的一些实施例中，所述外通道前端固定有支架，所述摄像组件固定在支架内，所述支架上设有便于排液的通孔。支架起到定位和固定摄像组件的作用，通孔增加气液排出的通道，增大流速。
在上述内窥镜的一些实施例中，所述摄像组件包括摄像装置和照明装置，所述摄像装置和照明装置的后端连接有控制线缆，提高内窥镜的产品质量。
在上述内窥镜的一些实施例中，所述插入管或握持部件上设置有进液口，所述子通道通过进液口连接有压泵装置，压泵装置加压将气体和液体输送至插入管的前端。
