内窥镜的点检是一项细致且重要的工作，它涉及到内窥镜的多个部位和功能的检查。以下是对内窥镜点检的详细介绍：

　　The inspection of endoscopes is a meticulous and important task that involves examining multiple parts and functions of the endoscope. The following is a detailed introduction to endoscopic inspection:

　　一、外观检查

　　1、 Appearance inspection

　　外观检查是从内窥镜的先端部到导光插头部逐项进行的，包括：

　　The appearance inspection is carried out item by item from the tip of the endoscope to the light guide plug, including:

　　1. 先端部：检查导光束盖玻璃、CCD盖玻璃、喷嘴、钳子管道口、先端帽有无破损、破裂。

　　1. Tip: Check for damage or breakage of the light guide beam cover glass, CCD cover glass, nozzle, pliers pipe mouth, and tip cap.

　　2. 弯曲部：检查弯曲橡皮、弯曲管有无老化、磨损、变形，以及黏合胶有无脱落或粗糙。

　　2. Bending part: Check whether the bending rubber and bending tube are aging, worn, deformed, and whether the adhesive is peeling or rough.

　　3. 插入部：检查插入管是否变形、被折、有刮痕、压扁或脏污，同时检查插入管标记是否脱落。

　　3. Insertion section: Check if the insertion tube is deformed, folded, scratched, flattened, or dirty, and also check if the marking on the insertion tube has come off.

　　4. 操作部：检查目镜盖玻璃是否破损，电子触点是否生锈氧化，吸引座是否磨损，角度旋钮和左右旋钮固定是否松动，按钮有无异响、破损或老化，以及铭牌有无遗失或脱落。

　　4. Operation Department: Check whether the eyepiece cover glass is damaged, whether the electronic contacts are rusted or oxidized, whether the suction seat is worn, whether the angle knob and left and right knobs are loose, whether the buttons have no abnormal noise, damage or aging, and whether the nameplate is lost or detached.

　　5. 导光软管：检查导光软管是否被折、变形或破损。

　　5. Light guide hose: Check if the light guide hose is bent, deformed, or damaged.

　　6. 导光插头部：检查导光杆有无松动，电子接点是否变形、生锈或氧化，以及水瓶借口O型圈是否磨损或老化。

　　6. Light guide plug part: Check whether the light guide rod is loose, whether the electronic contacts are deformed, rusted or oxidized, and whether the O-ring of the water bottle is worn or aged.

　　二、功能检查

　　2、 Function check

　　功能检查主要是测试内窥镜的各项功能是否正常，包括：

　　Functional inspection mainly tests whether the various functions of the endoscope are normal, including:

　　1. 图像质量：检查内窥镜的图像是否清晰，色彩是否还原度高。

　　1. Image quality: Check whether the image of the endoscope is clear and whether the color reproduction is high.

　　2. 弯曲角度：测试内窥镜的弯曲部是否能正常弯曲，且弯曲角度是否准确。

　　2. Bending angle: Test whether the bending part of the endoscope can bend normally and whether the bending angle is accurate.

　　3. 送气/送水功能：检查送气、送水功能是否正常，以及是否有漏水现象。

　　3. Air/water supply function: Check if the air and water supply functions are normal and if there is any water leakage.

　　4. 吸引功能：测试吸引功能是否顺畅，无负压造成粘膜损伤。

　　4. Attraction function: Test whether the attraction function is smooth and free from negative pressure causing mucosal damage.

　　5. 钳子管道插入性能：检查钳子管道是否能正常插入，以及插入时是否顺畅。

　　5. Plier tube insertion performance: Check whether the pliers tube can be inserted normally and whether it is inserted smoothly.

　　6. 其他按钮功能：检查如抬钳器功能、目镜变焦动作、吸引管清洁刷插入性能等其他按钮功能是否正常。

　　6. Other button functions: Check if other button functions such as clamp lift function, eyepiece zoom action, suction tube cleaning brush insertion performance, etc. are normal.

　　三、漏水测试

　　3、 Leakage test

　　漏水测试对于内窥镜故障预防尤其重要。如测漏不及时，漏水内窥镜继续使用，会造成故障范围扩大，如CCD烧毁，导像束龟裂，导光束硬化变脆断裂，金属部件生锈等，增加修理费用。测漏是早期发现内窥镜进水故障极为重要的工作，清洗消毒前务必按照正确的方法进行测漏。

　　Water leakage testing is particularly important for preventing endoscope malfunctions. If the leak detection is not carried out in a timely manner and the leaking endoscope continues to be used, it will cause the scope of the fault to expand, such as CCD burning, cracking of the image guide beam, hardening and brittle fracture of the light guide beam, rusting of metal parts, etc., increasing repair costs. Leak detection is an extremely important task for early detection of water ingress faults in endoscopes. Before cleaning and disinfecting, it is necessary to perform leak detection according to the correct method.

　　四、点检结束事项

　　4、 Completion of inspection items

　　内窥镜点检结束后，需注意以下几点：

　　After the endoscopic inspection is completed, the following points should be noted:

　　1. 关闭电源：关闭主机、光源、吸引器电源。

　　1. Power off: Turn off the power to the host, light source, and suction device.

　　2. 拆卸部件：拆卸水瓶及吸引管，拆卸电缆拔出内窥镜。

　　2. Disassemble components: Disassemble the water bottle and suction tube, remove the cable and pull out the endoscope.

　　3. 排出余水：取下水汽、吸引按钮，将内窥镜操作部倒置排出管道余水。

　　3. Discharge residual water: Remove the water vapor and suction button, invert the endoscope operating part to discharge the residual water in the pipeline.

　　4. 持续灌注：连接全管路灌流器持续推注空气，将管道余水排干。

　　4. Continuous infusion: Connect the entire pipeline injector to continuously inject air and drain the remaining water in the pipeline.

　　5. 擦拭外观：擦拭内窥镜外观，交于消毒。

　　5. Wipe appearance: Wipe the appearance of the endoscope and hand it over for disinfection.

　　6. 记录与通知：请综合判断点检过程中发现的故障和异常对使用功能和安全的影响，做好记录，及时通知相关人员。

　　6. Recording and notification: Please comprehensively assess the impact of faults and abnormalities discovered during the inspection process on the functionality and safety of use, keep records, and promptly notify relevant personnel.

　　通过以上的点检步骤，可以确保内窥镜在使用过程中能够保持良好的性能和准确性，从而保障医疗或工业检测的质量和安全。

　　Through the above inspection steps, it can be ensured that the endoscope can maintain good performance and accuracy during use, thereby ensuring the quality and safety of medical or industrial testing.
