内窥镜一旦出现故障，就会影响患者的治疗。那么，对内窥镜进行维修、精细化管理尤为重要。下面
内窥镜设备维修人员就来讲讲设备常见几个系统的故障。
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.
液体加压系统常见的故障
Common faults in liquid pressurization systems
（a）蠕动泵损坏。
(a) The peristaltic pump is damaged.
（b）液体压力传感器损坏。其原理基本与气体压力传感器相同。
(b) The liquid pressure sensor is damaged. Its principle is basically the same as gas pressure sensors.
（c）设备内部电路损坏。
(c) The internal circuit of the device is damaged.
电凝电切系统常见的故障
Common faults in electrocoagulation and electrocautery systems
（a）设备配件损坏，如脚踏开关，负极板导线，连接导线等常用的易损配件。
(a) Damaged equipment accessories, such as foot switches, negative electrode wires, connecting wires, and other commonly used vulnerable parts.
（b）电切，电凝，双极故障，在设备内部，这些部分都由不同的电路模块组成，我们可以根据其表现的故障现象对相应的模块电路进行维修或更换。
(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.
动力、消融系统常见的故障
Common faults in power and ablation systems
（a）动力系统主要是创削刀头的磨损和刨削手柄中的高能电机出现问题，而电机的更换是有选择性的，并不是每种电机都有更换配件的。因此在消毒和使用过程中要分外注意保护。
(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）消融系统在手术应用中主要是刀头的损耗。而设备故障多为电路故障，一般从输出部分着手。
(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.
冲洗吸引系统常见的故障
Common faults in flushing and suction systems
（a）压力或者吸力不足。设备中的双向泵老化，或者负压瓶漏气。
(a) Insufficient pressure or suction. The bidirectional pump in the equipment is aging, or the negative pressure bottle is leaking.
（b）设备无法开机一般多为液体进入设备，在没烧坏相关部件的情况下清理干净被错吸的液体就可以了。
(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.
