Description

一体式复合管 技术领域
本发明涉及的医疗器械的技术领域，特别是涉及一种使用在仪器上的一体式复合管。
背景技术
随着现代化科学技术的发展，内窥镜经过彻底改革，用上了光学纤维。纤内窥镜还可以用来做体内化验，如测量体内温度、压力、移位、光谱吸收以及其他数据。
光导纤维内窥镜是一条细长柔软的管子，管内有一束导光的玻璃纤维，两端各装有一个透镜。检查时将管子一端插入人体内部待查器官，从另一端即可看见器官内部的情况。内窥镜通常附有照明光源，有些还配备了进行手术治疗的器具，如激光器等。在光传输机理中引入了光纤，视频镜头成为图像捕捉的首选。现代视频内窥镜、电子内窥镜、超声内窥镜的出现又开辟了现代医学内镜的新纪元内窥镜从检查、诊断时代进入了治疗、手术的时代。
而目前使用在内窥镜上的管道因为需要进口，成本特别高，在现有技术中的管道内部的螺纹管疏密程度是不变的，采用PU一体成型。
因此，现有技术中的复合管存在以下几个问题：
内部螺纹管不区分疏密，从而可能复合管不能实现该硬的时候很硬，该软的部分比较软的情况，造成若使用内窥镜是拉的太紧，造成复合管的折断的情况；
因为现有技术中采用的是PU层，因此力的传输性、同轴性不高；
现有技术中是一体成型，蛇骨链部分之前采用焊接，精密度不高，且焊接部分比较细微，焊接不好就容易掉落；

附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例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发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其它的附图。其中：
图1为本发明提供的一体式复合管提供的一种实施例中的整体结构的局部剖视示意图；
图2为本发明提供的一体式复合管提供的一种实施例中所述螺纹管的整体结构示意图。
具体实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合说明书附图对本发明的具体实施方式做详细的说明。
在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是本发明还可以采用其他不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下做类似推广，因此本发明不受下面公开的具体实施例的限制。
其次，此处所称的“一个实施例”或“实施例”是指可包含于本发明至少一个实现方式中的特定特征、结构或特性。在本说明书中不同地方出现的“在一个实施例中”并非均指同一个实施例，也不是单独的或选择性的与其他实施例互相排斥的实施例。
实施例1
参照图1和图2，本发明提供了一体式复合管，在本发明的第一个实施例中，该一体式复合管的主体包括内层100、包覆层200和外层300，包覆层200包覆于所述内层100的外层，所述外层300包覆于所述包覆层200的外侧。
具体的，内层100包括螺纹管101和蛇骨链102，所述螺纹管101和所述 蛇骨链102两者一端相铰接。
现有技术中是一体成型，蛇骨链部分之前采用焊接，精密度不高，且焊接部分比较细微，焊接不好就容易掉落，因此，在本实施例中，蛇骨链102不采用焊接方式，采用铰接方式。
需要说明的是，内部螺纹管不区分疏密，从而可能复合管不能实现该硬的时候很硬，该软的部分比较软的情况，造成若使用内窥镜是拉的太紧，造成复合管的折断的情况。因为螺距越大，则螺距管的状态越软，越容易发生弯曲，且弹性越大，在使用的内窥镜中，若整根复合管很软的话，无法实现尾端弯曲，从而看到不同方向上的情况，如果整根复合管很硬的话，在弯曲看各个方向上的问题时，容易将复合管折断。因此，所述螺纹管101包括小螺距管101a、大螺距管101b和圆环管101c，且三者为一体式的，所述圆环管101c与所述蛇骨链102相铰接。
应当说明的是，小螺距管101a的螺距虽然小于大螺距管101b的螺距，但是小螺距管101a的每节螺纹管的宽度大于每节螺纹管的宽度，从而使得小螺距管101a的部分的硬度大于大螺距管101b的部分。
例如，将该一体式复合管应用于内窥镜上，当复合管深入到人体的肠胃中后，因为需要查看肠胃的优良状态时，需要在复合管的尾端做弯曲。若大螺距管101b位置弯曲时，小螺距管101a也弯曲的话，则达不到弯曲的效果。因此，采用上述实施方式，可以使得小螺距管101a的弯曲容易成都小于大螺距管101b的弯曲容易程度。
包覆层200套设于所述内层100的外侧，采用编织网包覆在内层100的外层，起到一个保护作用。
外层300包裹在所述包覆层200外侧，保证复合管的润滑度，不会在伸入到人体肠胃中后因为毛糙而割破人体的肠胃。
较佳的，所述包覆层200采用不锈钢、镍钛铝或铜择一使用。
