Description

一种内窥镜辅助接头
本申请要求于2021年09月27日提交中华人民共和国香港特别行政区知识产权署，申请编号为32021039515.0，名称为“一种内窥镜辅助接头”的短期专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及医疗器械技术领域，尤其涉及一种内窥镜辅助接头。
背景技术
随着科技的发展，内窥镜成为现代医学中常用的检测器械，其可以经口腔进入胃部或其他通道进入人体内，还可以通过手术形成的切口进入人体内。医生可以通过内窥镜观测人体内X射线无法显示的病变，有利于后续病情诊断。然而，内窥镜必须有相应的辅助组件配合一起才能安全和有效地进行操作，例如辅助接头，其与内窥镜连接，配合压力泵，使得生理盐水等液体通过此配件注入人体内。
目前有两种辅助接头，一种辅助接头是只能配合奥林巴斯内窥镜使用，如图1所示；另一种辅助接头是只能配合宾得内窥镜使用，如图2所示。显然，现有的辅助接头只能和奥林巴斯内窥镜或者宾得内窥镜配合，没有既可以和宾得内窥镜配合使用，也可以和奥林巴斯内窥镜配合使用的辅助接头，使得医护人员使用不同内窥镜时需要区分不同辅助接头，且也不便于医院管理存货。
申请内容
本申请提供了一种内窥镜辅助接头，用于解决目前没有既可以和宾得内窥镜配合使用，也可以和奥林巴斯内窥镜配合使用的辅助接头，使得医护人员使用不同内窥镜时需要区分不同辅助接头，且也不便于医院管理存货的技术问题。

具体实施方式
如图1所示，为市场上只能应用于奥林巴斯内窥镜的现有辅助接头1，从图1上可以看 出，辅助接头1内设有和奥林巴斯内窥镜接头相匹配的螺纹，当医护人员使用奥林巴斯内窥镜时，需要找出辅助接头1，将辅助接头1旋转扭动，从而使得辅助接头1和奥林巴斯内窥镜连通。如图2所示，为市场上只能应用于宾得内窥镜的现有辅助接头2，从图2上可以看出，辅助接头2内设有和宾得内窥镜接头相匹配的螺纹，当医护人员使用宾得内窥镜时，需要找出辅助接头2，将辅助接头2旋转扭动，从而使得辅助接头2和宾得内窥镜连通。显然，现有的辅助接头1和辅助接头2都只能分别应用于一种内窥镜，不具有能配合应用于不同内窥镜的结构。
有鉴于此，本申请实施例提供了一种内窥镜辅助接头，用于解决目前没有既可以和宾得内窥镜配合使用，也可以和奥林巴斯内窥镜配合使用的辅助接头，使得医护人员使用不同内窥镜时需要区分不同辅助接头，且也不便于医院管理存货的技术问题。
为使得本申请的发明目的、特征、优点能够更加的明显和易懂，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，下面所描述的实施例仅仅是本申请一部分实施例，而非全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
请参阅图1至图8，本申请实施例提供了一种内窥镜辅助接头，包括接头主体300、第一接头件100和第二接头件200，第一接头件100、第二接头件200和接头主体300依次组装后形成管道，管道和内窥镜连通；第二接头件200的第一端嵌设于第一接头件100的第一端内，第二接头件200的第二端嵌设于接头主体300的第一端内；第一接头件100的第二端内壁设有内螺纹101，第二接头件200靠近第一接头件100的位置处设有外螺纹201。
需要说明的是，接头主体300为单向阀鲁尔接头，本实施例提供的辅助接头包括第一接头件100和第二接头件200，第一接头件100设有内螺纹101，第二接头件200设有外螺纹201，当医护人员使用奥林巴斯内窥镜时，可以通过本实施例提供的辅助接头，令第一接头件100的内螺纹101对准现有奥林巴斯内窥镜的接头，并旋转扭动辅助接头，第一接头件100的内螺纹101和现有奥林巴斯内窥镜的接头紧密连接；当医护人员使用宾得内窥镜时，可以通过本实施例提供的辅助接头，令第二接头件200的外螺纹201对准现有宾得内窥镜的接头，并旋转扭动辅助接头，此时，第一接头件100也进入宾得内窥镜的接头中，且第二接头件200的外螺纹201和现有宾得内窥镜的接头紧密连接。因此，本实施例中的辅助接头不仅具有和现有奥林巴斯内窥镜连接的结构，还具有和现有宾得奥林巴斯内窥镜连接的结构，整体结构比较简单，不仅降低了医院的仓储管理成本，还节省了医护人员查找医疗物品的时间，从而大大降低了错误匹配以及损坏内窥镜的风险。
此外，本实施例可以通过超声焊接将第一接头件100和第二接头件200焊接起来，以加强第一接头件100和第二接头件200的连接稳定性。
进一步地，第一接头件100的第一端内壁由外向内呈阶梯状；第二接头件200的第二端包括第一凸起部202和螺纹部203，第一凸起部202嵌设于第一接头件100的第一端内壁， 外螺纹201设于螺纹部203。本实施例将第一接头件100的第一端内壁设置为阶梯状，当第一凸起部202嵌设在第一接头件100的第一端内壁时，可以提高第一接头件100和第二接头件200之间的连接稳定性。
进一步地，本实施例将第一凸起部202的直径设置成小于螺纹部203的直径，从而增加了第一接头件100和第二接头件200嵌设的接触面积，从而提高两者连接的稳定性。
进一步地，包括具有密封性能的密封圈400，本实施例中的密封圈400套设于第一凸起部202，且密封圈400的两侧分别与第一接头件100和螺纹部203过盈配合。可以理解的是，当第一凸起部202嵌设在第一接头件100的第一端内壁时，使得第一凸起部202有部分区域裸露在外界，将密封圈400套设在该裸露在外界的部分区域时，由于螺纹部203和第一接头件100两侧夹紧，可以大大地提高辅助接头的密封性。
进一步地，包括密封套500，第一接头件100的第一端内壁由外向内包括外阶梯层(图中未示)和内阶梯层(图中未示)，第一凸起部202嵌设于外阶梯层，密封套500设于内阶梯层。需要说明的是，密封套500为锥形密封套并与内阶梯层的形状匹配，在内阶梯层设置锥形密封套，不仅可以提高密封性，还可以增加辅助接头整体结构的紧固性。当然为了使得第一接头件100、第二接头件200和接头主体300依次组装后形成管道与现有内窥镜连通，本实施例中的密封套500也是中空设置。
进一步地，内螺纹101的直径大于内阶梯层的直径。
进一步地，第二接头件200的中部向外凸起形成第二凸起部204。
进一步地，接头主体300的第一端中部向所述第二接头件200延伸形成长筒柱301；所述长筒柱301和所述接头主体300外壁之间形成卡槽302，所述长筒柱301嵌插于第二接头件200的第二端内壁，第二接头件200的第二端卡接于卡槽302。
本实施例中的辅助接头包括第一接头件100、第二接头件200和接头主体300，第一接头件100、第二接头件200和接头主体300依次组装后形成管道，通过设于第一接头件100的内螺纹101可以使得辅助接头和奥林巴斯内窥镜连接，通过设于第二接头件200的外螺纹201可以使得辅助接头和宾得内窥镜连接，因此，本申请提供的辅助接头既可以和奥林巴斯内窥镜配合使用，也可以和宾得内窥镜配合使用，不需要仓管人员分别管理不同的接头，且当医护人员使用不同品牌的内窥镜时，无需区分，从而解决了目前没有既可以和宾得内窥镜配合使用，也可以和奥林巴斯内窥镜配合使用的辅助接头，使得医护人员使用不同内窥镜时需要区分不同辅助接头，且也不便于医院管理存货的技术问题。

在本申请实施例的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可更换连接，或一体地连接，可以是机械连接，也可以是电连接，可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请实施例中的具体含义。
以上所述，以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
