Endoscopy has become an indispensable medical equipment in the medical field, which can help people better observe the condition of organs in the body. Under what circumstances do medical endoscopes need to be repaired?

　　一、壓力顯現(xiàn)不正確。這多是氣體壓力傳感器損壞，假如機(jī)器規(guī)劃有一組多個(gè)壓差壓力傳感器同時(shí)作業(yè)的，一般一個(gè)老化或者污染無法作業(yè)的時(shí)候，我們要把這組傳感器全部替換，不然只換其間一個(gè)，其他的同組的傳感器壽數(shù)也挨近臨界了。

　　1、 The pressure appears to be incorrect. This is mostly due to the damage of the gas pressure sensor. If the machine is planned to have a group of multiple differential pressure sensors working at the same time, generally when an aging or pollution can not work, we should replace all of these sensors, otherwise only one of them will be replaced, and the service life of other sensors in the same group will be close to the critical value.

　　二、流量不準(zhǔn)確。氣體流量傳感器損壞替換即可。有時(shí)候是通過壓差來計(jì)算流量的，這時(shí)候我們就要替換新的壓差傳感器。

　　2、 The flow rate is not accurate. Replace the damaged gas flow sensor. Sometimes the flow rate is calculated by differential pressure. At this time, we have to replace the new differential pressure sensor.

　　三、設(shè)備漏氣。很多情況是器械密封圈老化而引起的。但也有設(shè)備機(jī)械減壓閥漏氣和電磁閥損壞的原因，這個(gè)比較簡單判別出并對其進(jìn)行修正。

　　3、 Air leakage of equipment. Many cases are caused by the aging of instrument sealing ring. But there are also reasons for the leakage of the mechanical pressure reducing valve and the damage of the solenoid valve, which is relatively simple to identify and correct.
                  

　　內(nèi)窺鏡在200年多年的開展過程中結(jié)構(gòu)發(fā)生了4次大的改善，從剛開始的硬管式內(nèi)窺鏡（1806-1932）、半曲式內(nèi)窺鏡（1932-1957）到纖維內(nèi)窺鏡（1957今后），又到現(xiàn)在的電子內(nèi)窺鏡（1983年今后）。影像質(zhì)量也發(fā)生了一次次質(zhì)的騰躍。

　　The structure of endoscope has been improved four times in the course of more than 200 years, from hard tube endoscope (1806-1932), semicircular endoscope (1932-1957), fiber endoscope (1957-1957), and now electronic endoscope (1983). The image quality has also undergone a qualitative leap.

　　醫(yī)用內(nèi)窺鏡是一種常用的醫(yī)療器械，由可曲折部分、光源及一組鏡頭組成。 經(jīng)人體的天然孔道，或是經(jīng)過手術(shù)做的小切斷進(jìn)入人體體內(nèi)。使用時(shí)將內(nèi)窺鏡導(dǎo)入預(yù)查看的器官，可直接窺探有關(guān)部位的變化。

　　Medical endoscope is a kind of commonly used medical equipment, which is composed of zigzag part, light source and a group of lenses. Through the human body's natural channels, or through small surgical cut-off into the body. When in use, the endoscope can be introduced into the organs to be examined, and the changes of relevant parts can be observed directly.

　　手術(shù)中使用內(nèi)窺鏡是非常普遍的了，不過還是要注意使用方式以及及時(shí)維修。

　　The use of endoscopes in surgery is very common, but we still need to pay attention to the use and timely maintenance.

　　一、手術(shù)時(shí)禁止大力彎折或碰撞

　　1、 Do not bend or collide vigorously during operation

　　二、運(yùn)用輔佐設(shè)備時(shí)要保證在視界內(nèi)安全操作，當(dāng)窺鏡配合激光汽化、高頻電切、微波等光電技能進(jìn)行手術(shù)時(shí)，應(yīng)留意窺鏡前端與醫(yī)治點(diǎn)的距離，保證窺鏡前端不被電擊或炙烤。

　　2、 When using the auxiliary equipment, it is necessary to ensure safe operation within the visual field. When the endoscope is operated with photoelectric skills such as laser vaporization, high-frequency electrosurgical excision and microwave, the distance between the front end of the endoscope and the treatment point should be noted to ensure that the front end of the endoscope is not shocked or roasted.

　　三、術(shù)中調(diào)整視界視點(diǎn)時(shí)需保護(hù)好鏡子本身，鏡子與鞘管鏈接時(shí)必須對準(zhǔn)方位并用卡鎖固定，不易過猛。

　　Three, during the adjustment of the view point, the mirror itself must be protected. When the mirror is linked to the sheath tube, it must be aligned to the position and fixed with a card lock.
