Description

带一次性可拆卸部件的医用内窥镜 技术领域
本发明涉及医疗器械技术领域, 具体涉及带一次性可拆卸部件的医用内窥 镜。 背景技术
内窥镜是一种常用的医疗器械, 由设置在操作部前端的插入部、 弯曲部和 前端部组成, 其中插入部、 弯曲部和前端部合称为插入管。 经人体的天然孔道, 或者是经手术做的小切口进入人体内; 使用时将内窥镜的插入管导入预检查的 器官, 可直接窥视有关部位的变化。
内窥镜是一种娇贵的医疗器械, 国内医用内窥镜市场大部分被国外品牌占 有, 价格从几万到几十万不等, 每次用后要进行复杂且高成本的消毒、 维护,即 使这样, 仍有可能因消毒工序不规范导致交叉感染。 传统的内窥镜插入管内设 置有送气 /送水通道、 吸引通道和活检通道及控制线缆、 信号电缆和导光纤维。 细长的通道彻底消毒非常困难, 但由于目前内窥镜的制作成本昂贵, 必须重复 使用。 有必要对传统内窥镜进行改进, 降低费用和交叉感染的风险。
后来逐渐出现了一次性产品, 中国发明专利 "201110056640.0"公开了 "一 种净化式医用内窥镜", 其结构是: 包括有内窥镜软性总体外壳, 内窥镜软性总 体外壳内设置有内窥镜主体, 内窥镜主体由医用树脂材料将成像镜头组件、 LED 光源和光纤导光束、 电源线和信号线包箍在一起, 内窥镜主体内设置有各种通 道。
上述技术存在以下问题: 整体釆用医用树脂或软性材料制成, 其刚性差, 在使用时, 并不能直达患处, 并且弯曲角度小, 适用范围窄。 内窥镜主体和内 窥镜软性总体外壳仍需消毒灭菌, 并未实现真正意义上的一次性使用。
中国发明专利 "200880017615.8" 公开了 "一种内窥镜弯曲部", 该内窥镜 弯曲部包括具有筒状部的、 互相同轴地并列设置的多个节环, 相邻的两个节环 中的一个节环具有与筒状部一体设置的、 沿筒状部的径向延伸的突出部, 相邻 的两个节环中的另一个节环具有与筒状部一体设置的、 供突出部能够以突出部 的长度轴线为中心转动地插入的承受部, 各节环, 具有在筒状部, 中与筒状部 的圓周方向交叉地延伸的非接合或者接合完毕的不连续部。
上述发明专利公开的一种内窥镜弯曲部, 结构复杂, 制造难度高, 生产成 本高, 不符合一次性内窥镜的制作要求。
目前要解决的一次性内窥镜的制造, 必须解决三个问题: 1、 成本, 传统的 内窥镜造价数十万元, 各部件的造价昂贵, 不可能直接丟弃, 2、 工作通道的消 毒问题, 目前未有相关技术能够对细长的管道进行彻底消毒, 3、 一次性内窥镜 必须将涉及工作通道的部件拆卸丟弃, 各部件直接如何设置及连接。
因此, 针对现有技术中的存在问题, 亟需提供一种生产成本低, 性能可靠、 拆卸方便的一次性医用内窥镜的技术。
