內窺鏡漏水的故障
Water leakage fault of endoscope
1、漏水會造成內部潤滑劑失效、角度鋼絲生銹，使角度操作時阻力變大。
1. Water leakage will cause failure of internal lubricant and rust of angle steel wire, which will increase the resistance during angle operation.
2、漏水后內部處于潮濕狀態容易使金屬焊接零件脫落，從而內鏡無法操作。
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、為保證操作性能，確保使用中的安全，需要更換插入管和彎曲管。
3. To ensure the operation performance and safety in use, it is necessary to replace the insertion tube and the bending tube.
4、由于先端排列的空間緊密，按照維修工序和技術標準要求，需要一同更換水氣管。
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.
一旦發生漏水，鏡腔內的水分和潮氣會影響光學系統、照明系統以及零件的性能，導致內鏡的使用功能下降。
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.
由于進水會影響其它零件性能，有時僅對漏水部位進行修理無法保證內鏡的操作性能。另外由于從外觀無法判斷漏水的程度，所以需要分解內鏡判斷需要更換的零件。
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.
內窺鏡角度彎曲異常問題
Abnormal bending of endoscope angle
1、彎曲管和插入管組裝時采用粘結固定方式，為不可拆分的組件，不能單獨更換其中一個。
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、彎曲管劣化、插入管壓扁可能會傷及內部的零件或使管道變形，需要對管道更換。
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、由于維修拆卸的工序要求，鉗子管道和水氣管會有破損從而不能使用。
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.
維修方式的多樣性
Diversity of maintenance methods
⑴故障部位部分零件不更換后，使用內鏡時低限度保證安全上、性能上沒有問題。
(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、零件不更換部位，需要用戶理解存在發生故障的風險。
(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!
