先端弯曲部

Bend at the tip

1）镜头的损伤有污物

1) Damage to the lens with dirt

预防方法：小心谨慎，避免碰撞，清洗过程中应使用清洁纱布擦拭镜面。

Prevention method: Be cautious and avoid collisions. During the cleaning process, clean the mirror surface with a clean gauze.

2）喷嘴堵塞

2) Nozzle blockage

预防方法：使用专用清洗按钮进行清洗。专用清洗按钮不可用于操作病人。

Prevention method: Use a dedicated cleaning button for cleaning. The dedicated cleaning button cannot be used to operate patients.

3）先端弯曲部弯曲橡皮针孔、重叠、破裂或变形

3) Bending of rubber needle holes, overlapping, cracking or deformation at the tip bending part

预防方法：①内窥镜设备维修人员提醒您，勿把内镜与其他器械一起放置，避免其他部位重压；②用纱布或纸巾蘸取洗涤液，从操作部开始清洗擦拭；③EVIS内镜环氧乙烷灭菌的时候取下防水帽，其他内镜环氧乙烷灭菌的时候带上ETO帽。

Prevention method: ① The maintenance personnel of the endoscope equipment remind you not to place the endoscope together with other instruments to avoid heavy pressure on other parts; ② Dip a piece of gauze or tissue in the washing solution and start cleaning and wiping from the operating section; ③ Remove the waterproof cap during EVIS endoscopic ethylene oxide sterilization, and wear the ETO cap during other endoscopic ethylene oxide sterilization.

4）弯曲管的损伤

4) Damage to bent pipes

预防方法：给患者带上口垫后再插入内窥镜，因为插入部较长，务必事先确认没有被夹住。

Prevention method: Put a mouth pad on the patient before inserting the endoscope, as the insertion part is long, make sure to confirm in advance that it is not pinched.

插入部

Insertion part

1）结晶

1) Crystallization

预防方法：①应及时床侧清洗，去除大量黏液；②使用酶洁液分解表面蛋白质；③流水下清洗表面，防止残留蛋白质与戊二醛接触结晶。

Prevention methods: ① The bed side should be cleaned in a timely manner to remove a large amount of mucus; ② Use enzyme cleaning solution to decompose surface proteins; ③ Clean the surface under running water to prevent residual proteins from crystallizing in contact with glutaraldehyde.

2）蛇管的损伤，导像束的折伤

2) Damage to the snake tube, damage to the guiding image bundle

预防方法：①插入部打圆的时候，角度勿小于说明书标示范围直径12cm；②操作中尽量将护套部伸直；③因为插入部较长，务必事先确认没有被意外夹住。

Prevention method: ① When rounding the insertion part, the angle should not be less than the diameter indicated in the instruction manual by 12cm; ② During operation, try to straighten the sheath as much as possible; ③ Because the insertion part is long, it is important to confirm in advance that it has not been accidentally clamped.

3）钳子管道针孔

3) Pinhole for pliers pipeline

预防方法：①务必将内镜先端至放松状态，以免在弯曲部插入时受阻，强行通过后会造成钳子管道受损；②等到附件伸出钳子管道口以后再释放针头；③闭合活检钳后插拔；④使用没有问题的活检钳。钳子管道有针孔无法从外观上发现需进行漏水测试，若测漏过程中钳子管道插入口及钳子管道出入口连续冒气泡，说明钳子管道有针孔，勿继续使用，以免造成更严重的损伤。

Prevention method: ① Be sure to place the tip of the endoscope in a relaxed state to avoid obstruction when inserting the curved part, which may cause damage to the forceps pipeline after forceful passage; ② Wait until the attachment extends out of the pliers pipe mouth before releasing the needle; ③ Close the biopsy forceps and insert and remove them; ④ Use a biopsy forceps without any issues. If there are pinholes in the pliers pipeline that cannot be detected from the appearance, a water leakage test is required. If there are continuous bubbles at the insertion port and inlet/outlet of the pliers pipeline during the leakage testing process, it indicates that the pliers pipeline has pinholes and should not be used again to avoid more serious damage.

操作部

Operations Department

1）遥控按钮漏水、旋钮漏水

1) Remote control button leaking, knob leaking

预防方法：①请勿将内窥镜与治疗附件重叠放置在水池里；②正确的握姿能避免控制开关与周边设备的碰撞。

Prevention method: ① Do not overlap the endoscope and treatment accessories in the pool; ② The correct grip posture can avoid collisions between the control switch and surrounding devices.

2）吸引口的磨损，吸引按钮处滴水，严重时液体飞溅无法正常吸引

2) Wear and tear of the suction port, water dripping at the suction button, and in severe cases, liquid splashing cannot attract properly

预防方法：手指应托住下方，再水平抽出附件。

Prevention method: Hold your fingers below and then horizontally pull out the attachment.

导光插头部

Light guide plug part

导光插头部电气接点氧化，电气接头腐蚀，内部进液

The electrical contact of the light guide plug is oxidized, the electrical connector is corroded, and there is internal liquid ingress

预防方法：①在需要全浸泡时必须先取下ETO帽，防止水从通气接口进入内镜；②在需要全浸泡时必须带上防水帽，防止内镜浸水。

Prevention method: ① When full immersion is required, the ETO cap must be removed first to prevent water from entering the endoscope through the ventilation interface; ② When full immersion is required, a waterproof cap must be worn to prevent immersion of the endoscope.
