Description

一种带冲洗抽吸功能的软硬结合内窥镜 技术领域
本发明属于内窥镜器械技术领域，具体涉及一种带冲洗抽吸功能的软硬结合内窥镜。
背景技术
内窥镜是集中了传统光学、人体工程学、精密机械、现代电子、数学、软件等于一体的检测仪器。一个具有图像传感器、光学镜头、光源照明、机械装置等，它可以经口腔进入胃内或经其他天然孔道进入体内。利用内窥镜可以看到X射线不能显示的病变，因此它对医生非常有用；根据内镜的构造特点，内窥镜可分为软式内镜和硬式内镜；
硬式内镜主要进入人体无菌组织、器官或者经外科切口进入人体无菌腔室，如腹腔镜、胸腔镜、关节镜、椎间盘镜、脑室镜等；由于硬式内窥镜镜身本体不可弯折，其路径只可为直线，但是在部分腔道内由于弯折角度影响，硬式的镜身无法顺利进入，给镜检造成阻碍；并且目前的硬式内窥镜只可起到提供腔道内图像视野的作用，但是当腔道内由于血液等形成视野遮挡时，硬式内窥镜无法处理；另外目前的硬镜查看图像的方式为通过硬镜上的目镜，目镜肉眼查看图像不够清晰，并且旁人无法看到；或将图像传输至体积较大的图像接收端，不方便携带可移动。
发明内容
为了解决上述技术问题，本发明设计了一种带冲洗抽吸功能的软硬结合内窥镜，该内窥镜头端为镜身可弯曲的软镜部分，后端为正常硬镜结构，镜身内设置冲洗通道和引流通道，可以对腔道内进行冲洗且将冲洗液引出，保证腔道内视野的清晰；
为了达到上述技术目的，本发明是通过以下技术方案实现的：一种带冲洗抽吸功能的软硬结合内窥镜，其特征在于，包括：硬镜外管、软镜外管，所述硬镜外管头端连接软镜外管，硬镜外管尾端连接操作柄，操作柄尾端可拆卸的连接显像设备；软镜外管和硬镜外管内部设 置有导光纤维排布通道、图像传输线及内撑条通道、冲洗通道、引流通道；其中在导光纤维排布通道内分布有导光纤维，图像传输线及内撑条通道内可活动的设置有内撑条；
优选的，所述操作柄上侧连接光源连接端，导光纤维的尾端与光源连接端对接，光源连接端上可拆卸的安装光源；
优选的，所述操作柄下侧分别连接着负压设备连接端和冲洗设备连接端，冲洗通道尾端与冲洗设备连接端对接，引流通道尾端与负压设备连接端对接；
优选的，所述图像传输线及内撑条通道尾端连接显像连接端，显像连接端上可拆卸的与显像设备对接；在图像传输线及内撑条通道穿过图像传输线和一条内撑条，且内撑条尾端从图像传输线及内撑条通道穿出，再穿过操作柄位于外部连接手柄；图像传输线头端连接微型摄像头，尾端连接显像连接端；
优选的，所述内撑条选用可弯曲且具有支撑性的材质制作。
本发明的有益效果是：
本发明设计的硬式内窥镜，在传统硬镜的基础上做出突出的改进，在硬式镜身前端设计软式镜身，方便进入一些硬式镜身无法进入的腔道；装置设计有冲洗和引流功能，可以对腔道血液进行冲洗，并将冲洗液引出，方便暴露清晰的视野；另外，装置可直接对接便携移动式的显像设备，通过便携移动式显像设备一方面可清晰观察腔道图像视野，另一方面也方便旁人进行腔道图像观察。

实施例1
参阅图1至图3所示，一种带冲洗抽吸功能的软硬结合内窥镜，其特征在于，包括：硬镜外管1、软镜外管2，所述硬镜外管1头端连接软镜外管2，硬镜外管1尾端连接操作柄3，操作柄3尾端可拆卸的连接显像设备4；软镜外管2和硬镜外管1内部设置有导光纤维排布通道5、图像传输线及内撑条通道6、冲洗通道7、引流通道8；其中在导光纤维排布通道5内分布有导光纤维9，图像传输线及内撑条通道6内可活动的设置有内撑条10；
优选的，所述操作柄3上侧连接光源连接端301，导光纤维9的尾端与光源连接端301对接，光源连接端301上可拆卸的安装光源；光通过导光纤维9传输从软镜外管2头端散出，为腔道内提供光照；
优选的，所述操作柄3下侧分别连接着负压设备连接端302和冲洗设备连接端303，冲洗通道7尾端与冲洗设备连接端303对接，引流通道8尾端与负压设备连接端302对接；冲洗设备连接端303与负压设备连接端302分别可拆卸的安装冲洗装置和负压吸引装置，可以实现对腔道的冲洗和引流；
优选的，所述图像传输线及内撑条通道6尾端连接显像连接端304，显像连接端304上可拆卸的与显像设备4对接；在图像传输线 及内撑条通道6穿过图像传输线和一条内撑条10，且内撑条10尾端从图像传输线及内撑条通道6穿出，再穿过操作柄3位于外部且连接手柄；图像传输线头端连接微型摄像头，尾端连接显像连接端304；微型摄像头采集腔道内图像经由图像传输线和显像连接端304在显像设备4上呈现出腔道内实时图像；所述内撑条10选用可弯曲且具有支撑性的材质制作，手持内撑条手柄，往外抽，内撑条10头端逐渐的从软镜外管2内部的图像传输线及内撑条通道6离开，此时内部没有内撑条10的软镜外管2部分变得可弯曲，内撑条10完全离开软镜外管2内部的图像传输线及内撑条通道6后，软镜外管2变得完全可弯曲；相反的，手持内撑条手柄，往内推，内撑条10逐渐进入软镜外管2内部的图像传输线及内撑条通道6，此时软镜外管2由于内撑条10的作用，变得具有一定支撑性，方便在腔道内推送。
综上所述，本发明设计的硬式内窥镜，在传统硬镜的基础上做出突出的改进，在硬式镜身前端设计软式镜身，方便进入一些硬式镜身无法进入的腔道；装置设计有冲洗和引流功能，可以对腔道血液进行冲洗，并将冲洗液引出，方便暴露清晰的视野；另外，装置可直接对接便携移动式的显像设备，通过便携移动式显像设备一方面可清晰观察腔道图像视野，另一方面也方便旁人进行腔道图像观察。
