The regular maintenance of medical endoscope equipment is generally completed by the instrument keeper in cooperation with the engineering and technical personnel. It is an organized and planned maintenance measure that is carried out in a continuous cycle, which is conducive to the search after failure. The content and time of regular maintenance can be divided into three levels.

（1）一保：一般可以一個(gè)月至一個(gè)季度進(jìn)行一次。主要內(nèi)容除廠日常維護(hù)的工作外，可以拆開(kāi)機(jī)殼，清除各處積塵，污垢、異物、緊固螺絲、添加潤(rùn)滑劑；檢查務(wù)器件、元件有無(wú)磨損、變形、燒蝕、擊穿、松動(dòng)，受潮，老化、接地不好等情況；檢測(cè)各組電源電壓及紋波，檢查高壓部件運(yùn)行和接觸情況等。

(1) One guarantee: it can generally be carried out once a month to a quarter. In addition to the daily maintenance of the factory, the casing can be disassembled to remove dust, dirt and foreign matters, tighten screws and add lubricant; Check the service devices and components for wear, deformation, ablation, breakdown, looseness, moisture, aging, poor grounding, etc; Check the power supply voltage and ripple of each group, and check the operation and contact of high-voltage components.

（2）二保：一般可以半年至一年進(jìn)行一次。主要內(nèi)容除做好一保外，可以對(duì)整機(jī)控制臺(tái)上的各個(gè)儀表及操作控制系統(tǒng)的靈敏度，精度進(jìn)行測(cè)試校正和計(jì)量檢定，更換高壓發(fā)生器絕緣汕等到期的損耗品，對(duì)電路中各測(cè)試點(diǎn)的電壓，波形進(jìn)行系統(tǒng)檢測(cè)和做拉偏試驗(yàn)。

(2) Second insurance: generally, it can be carried out once every six months to once a year. In addition to the first guarantee, it can test, correct and measure the sensitivity and accuracy of each instrument and operation control system on the console of the whole machine, replace the expired loss products such as the insulation of the high-voltage generator, systematically detect the voltage and waveform of each test point in the circuit and do the pull bias test.

（3）三保：一般可以2-4年進(jìn)行一次：主要內(nèi)容除做好二保外，必要寸可以將整機(jī)進(jìn)行全部拆卸子以清洗檢修，超過(guò)使用期的元器件應(yīng)盡量更換或修復(fù)，應(yīng)對(duì)儀器進(jìn)行較為徹 底的調(diào)試，恢復(fù)其工作精度和性能，達(dá)到或超過(guò)新機(jī)的程度是完全有可能的。

(3) Three Guarantees: generally, it can be carried out once every 2-4 years: in addition to the second guarantee, the whole machine can be disassembled for cleaning and maintenance if necessary. The components that exceed the service life shall be replaced or repaired as much as possible. It is entirely possible to thoroughly debug the instrument and restore its working accuracy and performance to reach or exceed the level of the new machine.

在醫(yī)院各科室中，醫(yī)療用內(nèi)窺鏡的使用其嚴(yán)格，內(nèi)窺鏡對(duì)使用環(huán)境的要求：室內(nèi)環(huán)境以暗室環(huán)境為主，避免強(qiáng)光直射，手術(shù)開(kāi)始關(guān)閉日光燈，用無(wú)影燈照明，術(shù)前室內(nèi)的溫度保持在22℃~25℃、濕度50%左右、防酸、防堿、防蒸氣。避免強(qiáng)電、電磁場(chǎng)的干擾。手術(shù)中確保電壓穩(wěn)定，連續(xù)穩(wěn)壓器維持電壓220V以免損壞精 密儀器。

In all departments of the hospital, the use of medical endoscopes is strict, and the requirements of endoscopes on the use environment: the indoor environment is mainly dark room environment to avoid direct strong light. The operation starts to turn off the fluorescent lamp and use shadowless lamp for lighting. Before operation, the indoor temperature is maintained at 22 ℃ ~ 25 ℃, the humidity is about 50%, acid, alkali and steam prevention. Avoid the interference of strong current and electromagnetic field. During the operation, the voltage shall be stable, and the continuous voltage regulator shall maintain the voltage of 220V to avoid damaging the precision instrument.

醫(yī)用內(nèi)窺鏡在不同的時(shí)期都促進(jìn)了醫(yī)學(xué)事業(yè)的不斷發(fā)展。今后隨著電子技術(shù)及其他科學(xué)技術(shù)的不斷進(jìn)步，相信其技術(shù)會(huì)有更廣更深的發(fā)展。

Medical endoscope has promoted the continuous development of medical cause in different periods. In the future, with the continuous progress of electronic technology and other science and technology, I believe its technology will have wider and deeper development.
