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?

　　醫用內窺鏡術后如何清理保養？先準備好相應的清洗設備與用物、器械清洗液、溶酶、去銹液及潤滑液等。清洗設備包括：流動水清洗消毒槽（三槽：清洗槽、酶洗槽、除銹槽）高壓水槍、干燥設備、計時器、通風設施、各種刷子、紗布、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.
              

　　醫用內窺鏡如何清洗？首先是殘留物的沖刷水洗：內鏡及器械手術完畢后立即卸開可卸部分，清洗槽內用流動水清洗，除去血液、黏液等殘留物質并擦干；曲卡及各類手術鉗、剪類器械、關節脫卸用軟毛刷子刷洗，高壓水槍沖洗各腔道、導管、管腔等。其次使用消毒酶洗：將擦干后的內鏡及器械置于1∶270酶洗液槽中浸泡、浸泡時間為30 min或用超聲清洗機振動清洗5 min~10 min。再來后續的沖洗：經酶洗液浸泡后的內鏡及器械放沖洗槽中用流動水清洗，有管腔器械在清洗過程中應用高壓水槍噴射沖洗，以去除管道內的酶洗液及松脫的污物。

　　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.

　　醫用內窺鏡還需要做一些護理，比如防銹去銹，器械經上述處理后，放入配好的1∶7去銹液內浸泡，浸泡時間為10 min，浸泡完后用清水沖洗。以及潤滑維護，沖洗后的器械放入1∶15潤滑液內浸泡，浸泡2 min~3 min后撈起晾干或燥干即可。

　　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.
