内镜操作部与导光插头部重叠，导光插头部的金属部件损伤遥控按钮，另外清洗、拿取内镜时，内镜操作部与周边物件发生碰撞。这就一定程度上给内窥镜钳道造成损伤，下面来分析下。

The endoscope operation part overlaps with the light guide plug part, and the metal part of the light guide plug head damages the remote control button. In addition, when cleaning and taking out the endoscope, the endoscope operation part collides with the surrounding objects. This will cause damage to the endoscopic forceps to a certain extent. Let's analyze it below.

原因分析：

Cause analysis:

1、钳子管道内释放枕头；

1. Release the pillow in the pliers pipe;

2、内镜先端部过度弯曲时强行插入注射针、活检钳等附件；

2. Forcibly insert injection needles, biopsy forceps and other accessories when the tip of the endoscope is excessively bent;

3、活检钳钳瓣张开的情况下插入或者拔出活检钳；

3. Insert or pull out the biopsy forceps when the biopsy forceps flap is open;

4、使用变形等质量不合格的活检钳；

4. Use deformed biopsy forceps with unqualified quality;

5、插入管弯曲角度太大后使用活检钳等附件。

5. Use biopsy forceps and other accessories after the bending angle of the insertion tube is too large.

预防方法：

Prevention methods:

如在使用内窥镜设备维修附件时感觉到异常阻力，请立即停止操作并查找原因：

If you feel abnormal resistance when using endoscope equipment to repair accessories, please stop the operation immediately and find the cause:

1、避免在内镜钳道内释放枕头或活检钳，一定要等枕头或活检钳从钳道内伸出以后，才能释放针头和打开活检钳钳瓣；

1. Avoid releasing pillows or biopsy forceps in the endoscopic forceps. Wait until the pillows or biopsy forceps protrude from the forceps before releasing the needle and opening the biopsy forceps flap;

2、插入活检钳、注射针的时候，应将内镜先端部处于放松的直线状态，便于活检钳、注射针等器械顺利通过；

2. When inserting biopsy forceps and injection needles, the tip of the endoscope should be in a relaxed linear state to facilitate the smooth passage of biopsy forceps, injection needles and other instruments;

3、避免使用变形等有质量问题的活检钳和其它治疗器械；

3. Avoid using biopsy forceps and other therapeutic instruments with quality problems such as deformation;

4、使用活检钳等附件时，切勿弯曲插入管。

4. Do not bend the insertion tube when using accessories such as biopsy forceps.

此外清洗消毒内镜的时候，内镜要整齐有序的盘放在清洗消毒槽里，避免镜身的重叠；正确的握姿能避免内镜与周边物件发生碰撞。更多相关内容就来网站http://www.jiangrenyiliao.cn关注咨询吧！

In addition, when cleaning and disinfecting the endoscope, the endoscope should be placed in the cleaning and disinfection tank in order to avoid the overlap of the mirror body; Correct grip posture can prevent the endoscope from colliding with surrounding objects.
