Description

内窥镜套管 技术领域
本发明涉及医疗器械技术领域， 具体涉及一种内窥镜套管。
 背景技术
目前，内窥镜在临床上已经被广泛的应用在肺部、胃部、肠部等部位的检查和治疗。目前内窥镜的插入部插入到人体的部位进行检查和治疗后必须要经过清清洗消毒才能进行再次使用，清洗消毒步骤繁琐，耗时较长，内窥镜轮转困难。且存在消毒不彻底的情况，容易造成交叉感染。目前，一次性使用内窥镜的插入部为使用完后对插入部进行抛弃，使用一次性内窥镜费用较高。且在治疗的过程中内窥镜头端会因器械的进入，内窥镜头端会发生移位，使治疗位置有所偏移。对内窥镜的插入部采用一次性内窥镜套管，内窥镜使用完后，只需要对内窥镜套管进行更换就能再次使用，即方便又便宜，且治疗位置更加准确。
目前的内窥镜套管与内窥镜进行配合使用时，只能用于脏器部位的检查，在检查使用过程中如有发现过多的血液、痰液等体液不能进行对液体的吸引。该内窥镜套管使用的范围和局限性很小。且对医生的使用存在很多的不方便，需要借助其他的医疗器械进行吸引。内窥镜头端在治疗时也会发生移动，使治疗位置有偏移。
因此，针对以上的内窥镜套管进行改进，增加带有吸引痰液、血液等体液的功能和在治疗时对内窥镜的头端进行固定的一种新型内窥镜套管。

参见图1与图4，本发明实施例提供一种内窥镜套管，包括套设在内窥镜外部的套管本体1以及将套管本体1与内窥镜固定的接头2，所述套管本体1采用弹性材料制成，所述的套管本体1内部沿其长度方向限定出相互独立的吸引通道4与内窥镜通道3，所述的内窥镜通道3一端设置为用于供内窥镜插入的开口5，另一端设置为封闭并形成可视窗，以供内窥镜观察头端环境；所述的接头2被配置在开口5处，并设有与开口5相适配的开孔；所述的吸引通道4自套管本体1近端纵向延伸至套管本体1远端，吸引通道4两端敞口设置，具有依次连接的远端开口6、空腔以及近端开口5，所述的远端开口6接近可视窗设置，所述的近端开口5包括吸引口7以及注水口8，所述的吸引口7连接吸引件9，所述的吸引件9外接吸引泵吸引所述远端开口6处的痰液至空腔，所述的注水口8将水、药物自所述空腔送至所述远端开口6。
内窥镜套管本体1采用弹性材料制成，即内窥镜通道3与吸引通道4均采用弹性材料制成，故在与内窥镜配套使用时，能够避免限制内窥镜的形变；同时吸引通道4采用支撑性能较优的弹性材质制成，既能保证吸引过程中避免发生吸引通道4外侧壁内陷问题（即防止通道被吸瘪），也能保证在使用过程中维持较好的拉伸形变效果。
另外，本套管中同步设有吸引通道4，在操作时，无需借助其他医疗器械即可对体液进行吸引，降低操作的难度以及减轻患者的不舒适感。
参见图1与图4所示，在手术操作时，内窥镜头端会因器械的进入发生移位，从而导致治疗位置出现偏差，故，所述的套管本体1头端的外管壁上设有球囊10，且所述球囊10连接有一个充气管11，在内窥镜置入到位时，对球囊10充气进而定位固定，防止移位；优选的，为保证在内窥镜使用过程中无影响，且不损伤自然腔道的黏膜，球囊10选用可充气的高容低压的超薄球囊10。
优选的，所述的接口采用硬质材料制成，可更好的保持内窥镜套管本体1与内窥镜结合使用时不会发生相对滑动，从而脱落的情况；进一步优选的，所述的接头2内设有密封阀门（此处未在图中示出），以能够密封所述的内窥镜通道3，具体的，密封阀门可选取弹性材料，内径从上至下逐渐减下，其下端与内窥镜可采取过盈配合的方式；或，密封阀门可采用现有市面上常用的结构。
