实施本发明的方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明所提到的“近端”和“远端”是从术者的角度来说的，术者使用本发明进行手术时，靠近术者一端称之为“近端”，远离术者一端称之为“远端”。
如图1所示，并结合图2-13所示，本发明一次成型十二指肠镜先端包括一次成型的先端本体2，先端本体2类似圆柱状，先端本体2的侧面上设有镜头组4、灯组5和容置腔8，容置腔8内设有抬钳器7，抬钳器7与先端本体2铰接，先端本体2的近端面上设有均与容置腔8连通的工作通道管进入孔11和控制线进入孔12，抬钳器7与控制线9的远端连接，控制线9的近端穿过控制线进入孔12延伸至先端本体2外，先端本体2上设有一容纳电路板17的空腔18，空腔18的开口处密封设有一封水片15，镜头组4和灯组5分别与空腔18内的电路板17连接，先端本体2的近端面上设有与空腔18连通的电缆线进入孔14，电路板17与电缆线的远端连接，电缆线的近端穿过电缆线进入孔14延伸至先端本体2外。
镜头组4和灯组5相邻设置，先端本体2的近端面上设有与镜头组4和灯组5相对应的喷水管进入孔13，在实际使用过程中，如果镜头组4和灯组5不清晰，可以通过喷水管进入孔13连接喷水管，用于清洗镜头组4和灯组5。先端本体2的侧面上设有喷水通道3，喷水通道3、镜头组4和灯组5均位于容置腔8的同一侧，喷水通道3的近端与喷水管进入孔13连通，喷水通道3的远端处设有镜头组4和灯组5，这样水流能够通过喷水通道3精准地到达镜头组4和灯组5进行清洗。
如图12所示，本发明一次成型十二指肠镜先端，其中抬钳器7呈条状，抬钳器7的近端通过销轴1铰接于容置腔8内的先端本体2上，抬钳器7的远端与控制线9的远端连接。
本发明一次成型十二指肠镜先端，其中抬钳器7的远端设有一套管10，套管10的一端位于抬钳器7远端内，套管10的另一端延伸至抬钳器7远端外，控制线9的远端连接于套管10的内腔，容置腔8的内壁上设有弧形滑台16，套管10的另一端位于弧形滑台16的台面上，当抬钳器7的远端抬起或落下时，套管10的另一端沿着弧形滑台16的台面滑动。
本发明一次成型十二指肠镜先端，其中抬钳器7呈弧形，如图2所示，并结合图3、4所示，抬钳器7为向下方凸起的弧形结构。抬钳器7的工作面上 设有条形凹槽6，条形凹槽6沿抬钳器7的长度方向布置。在抬钳器7工作面上设置条形凹槽6，便于手术器械放置，也便于抬钳器7抬起，防止手术器械从抬钳器7的工作面上滑落。
本发明一次成型十二指肠镜先端，其中控制线9为钢丝。在实际使用中，控制线9通常为由多根钢丝制成的钢丝束。
如图14所示，并结合图15-23所示，控制线进入孔12上连接有封水连接器，封水连接器包括柱状壳体，柱状壳体的远端与一护管21的近端连接，护管21的远端连接于控制线进入孔12内，柱状壳体内设有一活塞杆25，控制线9的近端穿过护管21进入柱状壳体内并穿过活塞杆25后从柱状壳体的近端穿出到柱状壳体外，控制线9通过螺钉22固定于活塞杆25上，活塞杆25与柱状壳体的近端之间设有弹簧24。
本发明在使用的时候，先端本体2的近端面的周向连接蛇骨，工作通道管进入孔11连接工作通道，喷水管进入孔13连接喷水管，将先端本体2伸入到人体内的预定位置后，将手术器械沿着工作通道管进入到抬钳器7的工作面上，之后再根据实际情况从远端向近端方向拉动控制线9，使抬钳器7抬起，从而改变手术器械的方向。术者通过镜头组4进行观察，灯组5提供照明，如果镜头组4和灯组5表明不干净的话，就通过喷水管向喷水通道3喷水，水从喷水通道3的远端喷出，清洗镜头组4和灯组5。
在拉动控制线9的时候是通过操作封水连接器实现的，具体为：从远端向近端方向拉动控制线9的近端，由于控制线9固定于活塞杆25上，因此活塞杆25沿着柱状壳体的内腔从远端向近端方向移动，于是控制线9的远端将抬钳器7抬起。在此过程中，人体内的体液会顺着控制线9进入到护管21里，但是进入到护管21里的体液很少，体液在护管21内的行程很短，不会沿着护管21进入到封水连接器的内腔里，因为(1)活塞杆25移动的距离较短，产生的负压较小，造成对体液的吸力不足，(2)护管21很长，大约设置为1.4米，需要较大的负压体液才能穿过，(3)控制线9为钢丝，通常为钢丝束，由于水存在张力，其并不会沿着控制线9移动。
在抬钳器7完成抬起工作后，松开控制线9的近端，由于弹簧24的作用，活塞杆25向柱状壳体的远端移动，与活塞杆25固定的控制线9也从近端向远端移动，于是抬钳器7落下。
本发明在清洗消毒的时候，将先端本体2置于消毒池内的消毒水中，之后从远端向近端方向拉动控制线9的近端，使活塞杆25在柱状壳体内产生较大的负压足以使消毒池内的消毒水进入护管21的行程大于体液进入护管21的行程(以便对护管21的内壁及护管21内的控制线9进行消毒)，之后再松开控制线9的近端，在弹簧24的作用下，活塞杆25向柱状壳体的远端移动，在气压的作用下再将护管21内的消毒水挤压到消毒池中。如此反复操作，即可完成清洗消毒工作。
本发明一次成型十二指肠镜先端，其中柱状壳体包括近端管19和远端管20，近端管19的远端与远端管20的近端螺纹连接。
本发明一次成型十二指肠镜先端，其中活塞杆25与柱状壳体的内侧壁之间设有O型密封圈23，O型密封圈23设于活塞杆25上，O型密封圈23能够增强活塞杆25与柱状壳体之间的密封性。活塞杆25的远端面与控制线9之间通过UV胶密封，起到防水的作用。
本发明中的先端本体2一次成型，先端本体2作为载体，其它件在其上装配为一体，因此体型小且无漏水处，清洗消毒非常容易，从而能够避免交叉感染。
本发明中的先端本体2一次成型，使先端集成了镜头组4、灯组5、喷水通道3、电路板17、电缆线、工作通道、抬钳器7和钢丝，其与蛇骨连接安装为一体化，即所有功能都能在先端上体现。
本发明尺寸更小，集成了所有功能为一体，加工工艺简单、制作容易，尺寸一致性好。因先端本体2为载体，其它件在其上装配为一体，无漏水处，清洗非常容易。
如图1所示，并结合图2-13所示，在实际装配中，先端本体2的组装工艺如下：(1)在先端内装入镜头组4→(2)装入电路板17并将导线从电缆 线进入孔14引出→(3)安装灯组5及电路板17处的封水片15→(4)将钢丝+套管10一体的配套件插入抬钳器7远端的侧孔中，将钢丝折弯90度后从控制线进入孔12穿出→(5)抬钳器7的近端侧孔安装销轴1与先端本体2铰接→(6)连接工作通道管、喷水管、蛇骨。
如图14所示，并结合图15-23所示，先端本体2与封水连接器的组装工艺如下：(1)护管21远端套在钢丝上并与先端本体2粘接→(2)钢丝穿过柱状壳体的远端管20，护管21近端与柱状壳体的远端管20粘接→(3)钢丝穿过活塞杆25内孔，在活塞杆25远端面凹坑内加入UV胶，使活塞杆25远端面与柱状壳体的远端管20端面齐平，用螺钉22将钢丝固定，照射UV胶固化(防水)→(4)活塞杆25近端套上弹簧24，钢丝穿过柱状壳体的近端管19，将柱状壳体的近端管19和远端管20螺纹连接。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
