Description

一种模块化内窥镜 技术领域
本发明涉及内窥镜技术领域，具体地指一种模块化内窥镜。
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，在医疗上应用十分广泛。它可以经口腔进入胃内或经其他天然孔道进入体内，能通过小切口进入体内看到X射线不能显示的病变，并且能配合手术器械在体内进行可视化手术治疗。临床上的体内检查及可视化手术治疗需要图像清晰的内窥镜来帮助医生提高诊断的准确性。但现有的内窥镜为一整体式结构，并集成了图像传感器、光学镜头、光源照明、治疗器械和工作鞘等机构，为使工作鞘更适用于临床治疗、观察病变部位，往往还集成了工作鞘弯曲机构、伸缩机构和旋转机构，因此内窥镜的制造成本高。在临床治疗过程中，为避免交叉感染，内窥镜属于一次性耗材，导致治疗成本高，尤其在手术治疗过程中，大大提高了手术费用，患者承受的经济负担重。
发明内容
本发明的目的就是要解决上述背景技术的不足，提供一种一次性结构少、治疗费用低且消耗成本低的模块化内窥镜结构。
为实现此目的，本发明所设计的模块化内窥镜结构，包括内窥镜手柄、内窥镜工作鞘和内窥镜管，所述内窥镜工作鞘的后端沿其轴向设有导向孔，所述导向孔内设有可沿导向孔轴向移动的第一连接销轴，所述导向孔与第一连接销轴之间存在阻尼；所述内窥镜手柄的前端沿其轴向设有导向孔，所述导向孔内设有可沿导向孔轴向移动的第二连接销轴，所述导向孔与第二连接销轴之间存在阻尼；所述内窥镜工作鞘后端的导向孔与第一连接销轴之间的阻尼力以及内窥镜手柄与第二连接销轴之间的阻尼力均大于第一连接销轴与第二连接销轴轴向配合的卡接力，所述第一连接销轴的后端与第二连接销轴的前端相互配合连接，所述内窥镜 工作鞘的后端与所述内窥镜手柄的前端相互配合连接；所述内窥镜手柄内设有能驱动第二连接销轴沿其轴向拉伸的张紧机构，所述内窥镜管包括前端伸出内窥镜工作鞘外的软管和后部固定于内窥镜工作鞘内的硬管，所述第一连接销轴通过钢丝绳连接所述软管的转向钢丝，所述第二连接销轴与所述张紧机构连接。
具体的，所述张紧机构包括设置于内窥镜手柄内的波轮杆，所述波轮杆通过钢丝绳与所述第二连接销轴固定连接，所述内窥镜手柄的后端设有与波轮杆两端固定连接的波轮。
本发明具有以下两种销轴连接形式和套筒配合形式：
