Medical endoscope is widely used in modern medical surgery, and occupies an important position in physical examination and minimally invasive surgery, which saves a lot of medical time. Important medical equipment needs special cleaning and maintenance, medical endoscope is no exception, so how to maintain it?

　　医用内窥镜术后如何清理保养？先准备好相应的清洗设备与用物、器械清洗液、溶酶、去锈液及润滑液等。清洗设备包括：流动水清洗消毒槽（三槽：清洗槽、酶洗槽、除锈槽）高压水枪、干燥设备、计时器、通风设施、各种刷子、纱布、棉棒等等。

　　How to clean and maintain medical endoscope after operation? First prepare the corresponding cleaning equipment and materials, instrument cleaning fluid, lysozyme, derusting fluid and lubricating fluid. Cleaning equipment includes: flowing water cleaning and disinfection tank (three tanks: cleaning tank, enzyme washing tank, rust removal tank), high-pressure water gun, drying equipment, timer, ventilation facilities, various brushes, gauze, cotton swabs, etc.
              

　　医用内窥镜如何清洗？首先是残留物的冲刷水洗：内镜及器械手术完毕后立即卸开可卸部分，清洗槽内用流动水清洗，除去血液、黏液等残留物质并擦干；曲卡及各类手术钳、剪类器械、关节脱卸用软毛刷子刷洗，高压水枪冲洗各腔道、导管、管腔等。其次使用消毒酶洗：将擦干后的内镜及器械置于1∶270酶洗液槽中浸泡、浸泡时间为30 min或用超声清洗机振动清洗5 min~10 min。再来后续的冲洗：经酶洗液浸泡后的内镜及器械放冲洗槽中用流动水清洗，有管腔器械在清洗过程中应用高压水枪喷射冲洗，以去除管道内的酶洗液及松脱的污物。

　　How to clean medical endoscope? The first is the washing and washing of residues: after the operation of endoscopes and instruments, the detachable parts should be removed immediately, and the cleaning tank should be cleaned with flowing water to remove the residual substances such as blood and mucus, and wipe them dry; the soft brush should be used to wash the trocar and all kinds of surgical forceps, cutting instruments and joint stripping, and high-pressure water gun should be used to wash the lumen, catheter and lumen. Then use disinfection enzyme washing: soak the dried endoscopes and instruments in a 1 ∶ 270 enzyme bath for 30 min, or use ultrasonic cleaning machine for 5 min ~ 10 min. Then the follow-up flushing: the endoscopes and instruments soaked in the enzyme lotion are put into the flushing tank and cleaned with flowing water. The instruments with lumen should be flushed with high-pressure water gun during the cleaning process to remove the enzyme lotion and loose dirt in the pipeline.

　　医用内窥镜还需要做一些护理，比如防锈去锈，器械经上述处理后，放入配好的1∶7去锈液内浸泡，浸泡时间为10 min，浸泡完后用清水冲洗。以及润滑维护，冲洗后的器械放入1∶15润滑液内浸泡，浸泡2 min~3 min后捞起晾干或燥干即可。

　　Medical endoscopes also need to do some care, such as rust prevention and rust removal. After the above treatment, the instrument is immersed in the prepared 1:7 rust removal solution for 10 min, and then washed with clean water. And lubrication maintenance: the washed instruments are immersed in 1:15 lubricating liquid, soaked for 2-3 minutes, and then picked up to dry or dry.
