內窺鏡一旦出現故障，就會影響患者的。那么，對內窺鏡進行維修、精細化管理尤為重要。下面
內窺鏡設備維修人員就來講講設備常見幾個系統的故障。
Once the endoscope malfunctions, it can affect the patient's treatment. So, it is particularly important to maintain and refine the management of the endoscope. Below, the endoscope equipment maintenance personnel will talk about several common system faults of the equipment.
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 gas pressure sensors.
（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 in electrocoagulation and electrocautery systems
（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 parts.
（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, bipolar faults are all composed of different circuit modules within the equipment. We can repair or replace the corresponding module circuits based on the fault symptoms they exhibit.
動力、消融系統常見的故障
Common faults in 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 mainly focuses on the wear of the cutting tool head and problems with the high-energy motor in the planing handle, and the replacement of the motor 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 application of ablation systems in surgery 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 flushing and suction systems
（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 bidirectional pump in the equipment is aging, or the negative pressure bottle is leaking.
（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 inability of the device to start is usually due to liquid entering the device. It is sufficient to clean the mistakenly aspirated liquid without burning the relevant components.
