醫用內窺鏡是一種常用的醫療器械，由可彎曲部分、光源及一組鏡頭組成。經人體的天然孔道，或是經過手術做的小切口進入人體體內。那么您知道內窺鏡設備的相關參數及故障包含什么嗎？下面內窺鏡設備維修人員給您講解。

Medical endoscope is a commonly used medical instrument, which consists of a flexible part, a light source and a group of lenses. It enters the human body through natural channels or small incisions made by surgery. Do you know what the relevant parameters and faults of the endoscope equipment include? The endoscope equipment maintenance personnel will explain to you below.

（1）光源系統常見的故障

(1) Common faults of light source system

光線發暗。排除了是光柵遮擋的原因外，基本可以肯定是燈泡接近使用壽命，更換新燈泡則可。氙光燈泡的使用壽命一般設計在500小時，如果光源系統有壽命計時裝置，這個問題就很容易解決。

The light is dim. It is ruled out that the light bulb is close to its service life, and it can be replaced with a new light bulb. The service life of xenon light bulb is generally designed to be 500 hours. If the light source system has a life timer, this problem can be easily solved.

開機燈泡不亮。如果排除了燒掉燈泡這個原因的話，那么問題常常就出在主機高壓點火電路部分，因為開機的時候機器會產生上萬伏特的脈沖高壓，元件會老化得特別快。注意此時不能用萬用表去檢查脈沖高壓。

The power on bulb does not light up. If the reason of burning out the bulb is ruled out, the problem is often in the high-voltage ignition circuit of the host, because the machine will generate tens of thousands of volts of pulse high voltage when it is turned on, and the components will age very quickly. Note that you cannot use a multimeter to check the pulse high voltage at this time.

（2）人工氣腹系統常見的故障

(2) Common faults of artificial pneumoperitoneum system

壓力顯示不正確。這多是氣體壓力傳感器損壞，如果機器設計有一組多個壓差壓力傳感器同時工作的，一般一個老化或者污染無法工作的時候，我們要把這組傳感器全部更換，否則只換其中一個，其他的同組的傳感器壽命也接近臨界了。

The pressure display is incorrect. This is mostly due to the damage of gas pressure sensors. If the machine is designed to have a group of multiple differential pressure sensors working at the same time, generally when one of them is aging or polluted and cannot work, we should replace all of these sensors, otherwise only one of them will be replaced, and the life of other sensors of the same group will also be near the critical point.

流量不準確。氣體流量傳感器損壞更換即可。有時候是通過壓差來計算流量的，這時候我們就要更換新的壓差傳感器。

The flow is not accurate. If the gas flow sensor is damaged, replace it. Sometimes the flow is calculated by differential pressure. At this time, we need to replace a new differential pressure sensor.

設備漏氣。很多情況是器械密封圈老化而引起的。但也有設備機械減壓閥漏氣和電磁閥損壞的原因，這個比較容易判斷出并對其進行修復。

The equipment leaks air. Many cases are caused by the aging of the device sealing ring. However, there are also reasons for leakage of mechanical pressure reducing valve and damage of solenoid valve, which can be easily identified and repaired.

（3）液體加壓系統常見的故障

(3) Common faults of liquid pressurizing system

蠕動泵損壞。

Peristaltic pump is damaged.

液體壓力傳感器損壞。其原理基本與氣體壓力傳感器相同。

The liquid pressure sensor is damaged. Its principle is basically the same as that of the gas pressure sensor.

設備內部電路損壞。

The internal circuit of the equipment is damaged.

（4）電凝電切系統常見的故障

(4) Common faults of electric coagulation and electric cutting system

設備配件損壞。如腳踏開關，負極板導線，連接導線等常用的易損配件。

The equipment accessories are damaged. Such as foot switch, negative plate wire, connecting wire and other commonly used vulnerable accessories.

電切、電凝，雙極故障。在設備內部，這些部分都由不同的電路模塊組成。我們可以根據其表現的故障現象對相應的模塊電路進行維修或更換。

Electric cutting, electrocoagulation, bipolar fault. Inside the equipment, these parts are composed of different circuit modules. We can repair or replace the corresponding module circuit according to the fault phenomenon.

如果是設備出問題，應該先采取應急維修，因為這樣能解決占故障85%左右的中小故障。而在實際維修的時候難解決的問題是更換配件的訂購。更多相關內容就來我們網站http://www.cnxgtzyj.cn進行咨詢了解吧！

If there is a problem with the equipment, emergency maintenance should be carried out first, because this can solve the small and medium faults that account for about 85% of the faults. The problem that is difficult to solve in actual maintenance is the ordering of replacement parts. More relevant content will come to our website http://www.cnxgtzyj.cn Consult and understand!
