内窥镜漏水的故障
Water leakage fault of endoscope
1、漏水会造成内部润滑剂失效、角度钢丝生锈，使角度操作时阻力变大。
1. Water leakage will cause failure of internal lubricant and rust of angle steel wire, which will increase the resistance during angle operation.
2、漏水后内部处于潮湿状态容易使金属焊接零件脱落，从而内镜无法操作。
2. After water leakage, the internal part is in a wet state, which is easy to make the metal welding parts fall off, so the endoscope cannot be operated.
3、为保证操作性能，确保使用中的安全，需要更换插入管和弯曲管。
3. To ensure the operation performance and safety in use, it is necessary to replace the insertion tube and the bending tube.
4、由于先端排列的空间紧密，按照维修工序和技术标准要求，需要一同更换水气管。
4. Due to the tight space arranged at the front, the water and gas pipes need to be replaced together according to the requirements of the maintenance process and technical standards.
一旦发生漏水，镜腔内的水分和潮气会影响光学系统、照明系统以及零件的性能，导致内镜的使用功能下降。
In case of water leakage, the water and moisture in the mirror cavity will affect the performance of the optical system, lighting system and parts, resulting in the decline of the use function of the endoscope.
由于进水会影响其它零件性能，有时仅对漏水部位进行修理无法保证内镜的操作性能。另外由于从外观无法判断漏水的程度，所以需要分解内镜判断需要更换的零件。
Since water inflow will affect the performance of other parts, sometimes only repairing the leaking part can not guarantee the operating performance of the endoscope. In addition, since the degree of water leakage cannot be judged from the appearance, it is necessary to disassemble the endoscope to judge the parts that need to be replaced.
内窥镜角度弯曲异常问题
Abnormal bending of endoscope angle
1、弯曲管和插入管组装时采用粘结固定方式，为不可拆分的组件，不能单独更换其中一个。
1. The bending tube and the insertion tube are fixed by bonding during assembly. They are inseparable components, and one of them cannot be replaced separately.
2、弯曲管劣化、插入管压扁可能会伤及内部的零件或使管道变形，需要对管道更换。
2. Deterioration of the bent pipe and flattening of the inserted pipe may damage the internal parts or deform the pipe, so the pipe needs to be replaced.
3、由于维修拆卸的工序要求，钳子管道和水气管会有破损从而不能使用。
3. Due to the process requirements of maintenance and disassembly, the pliers pipe and water and gas pipe will be damaged and cannot be used.
维修方式的多样性
Diversity of maintenance methods
⑴故障部位部分零件不更换后，使用内镜时低限度保证安全上、性能上没有问题。
(1) after some parts of the faulty parts are not replaced, the endoscope shall be used to ensure that there is no problem in safety and performance.
⑵由于不修理、零件不更换部位，需要用户理解存在发生故障的风险。
(2) since the parts are not repaired or replaced, users need to understand the risk of failure.
(2) the endoscope equipment maintenance personnel remind you that when there is a black shadow (affecting the diagnosis), the parts need to be replaced.
That's all for the maintenance of water leakage and abnormal angle bending of endoscope and other instruments. You can follow our website at www.jiangrenyiliao Cn, for more information about the website!
