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。但內窺鏡一旦出現故障，就會影響患者的。下面內窺鏡設備維修人員先來講講醫用內窺鏡多個系統的故障處理。

A medical endoscope is a commonly used medical device consisting of a flexible part, a light source, and a set of lenses. However, once the endoscope fails, it will affect the treatment of patients. The endoscope equipment maintenance personnel will first talk about troubleshooting multiple systems of medical endoscope.

人工氣腹系統常見的故障

Common faults of artificial pneumoperitoneum system

（a）壓力顯示不正確。

(a) The pressure display is incorrect.

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。

This is mostly due to damage to the gas pressure sensor. If the machine is designed with a group of multiple differential pressure sensors operating at the same time, usually when one of the sensors is aged or contaminated and cannot work, we need to replace all of this group of sensors, otherwise only one of them will be replaced, and the life of other sensors in the same group is also approaching the critical point.

（b）流量不準確。

(b) The flow rate is not accurate.

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。

Replace the damaged gas flow sensor. Sometimes the flow rate is calculated by pressure difference, and we need to replace it with a new pressure difference sensor.

（c）設備漏氣。

(c) Equipment leaks.

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。

Many cases are caused by aging of the instrument sealing ring. However, there are also reasons for leakage of the mechanical pressure reducing valve and damage to the solenoid valve of the equipment, which are relatively easy to identify and repair.

液體加壓系統常見的故障

Common faults in liquid pressurization systems

（a）蠕動泵損壞。

(a) The peristaltic pump is damaged.

（b）液體壓力傳感器損壞。其原理基本與氣體壓力傳感器相同。

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

（c）設備內部電路損壞。

(c) The internal circuit of the device is damaged.

電凝電切系統常見的故障

Common faults of electrocoagulation and electrocautery system

（a）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。

(a) Damaged equipment accessories, such as foot switches, negative electrode wires, connecting wires, and other commonly used vulnerable accessories.

（b）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。

(b) "Electric cutting, electrocoagulation, and bipolar faults are all composed of different circuit modules within the equipment. We can repair or replace the corresponding module circuits based on the symptoms of their faults.".

動力、消融系統常見的故障

Common faults of power and ablation systems

（a）動力系統主要是創削刀頭的磨損和刨削手柄中的高能電機出現問題，而電機的更換是有選擇性的，并不是每種電機都有更換配件的。因此在和使用過程中要分外注意保護。

(a) The power system is mainly caused by wear of the cutting head and problems with the high-energy motor in the planing handle. Motor replacement is selective, and not every type of motor has replacement accessories. Therefore, special attention should be paid to protection during disinfection and use.

（b）消融系統在手術應用中主要是刀頭的損耗。而設備故障多為電路故障，一般從輸出部分著手。

(b) The main reason for ablation systems in surgical applications is the loss of the blade. Equipment failures are mostly circuit failures, usually starting from the output part.

沖洗吸引系統常見的故障

Common faults in the flushing suction system

（a）壓力或者吸力不足。設備中的雙向泵老化，或者負壓瓶漏氣。

(a) Insufficient pressure or suction. The two-way pump in the equipment is aging, or the negative pressure bottle leaks.

（b）設備無法開機一般多為液體進入設備，在沒燒壞相關部件的情況下清理干凈被錯吸的液體就可以了。

(b) The reason why the device cannot be started up is usually liquid entering the device. It is sufficient to clean up the mistakenly aspirated liquid without burning the relevant components.

所以說，對內窺鏡進行維修、精細化管理尤為重要。更為詳細的內容就來我們網站http://www.dcgr.cn咨詢了解吧！
