医用内窥镜是一种常用的医疗器械，由可弯曲部分、光源及一组镜头组成。但内窥镜一旦出现故障，就会影响患者的治疗。下面内窥镜设备维修人员先来讲讲医用内窥镜多个系统的故障处理。

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.

人工气腹系统常见的故障

Common faults of artificial pneumoperitoneum system

（a）压力显示不正确。

(a) The pressure display is incorrect.

这多是气体压力传感器损坏，如果机器设计有一组多个压差压力传感器同时工作的，一般一个老化或者污染无法工作的时候，我们要把这组传感器全部更换，否则只换其中一个，其他的同组的传感器寿命也接近临界了。

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）流量不准确。

(b) The flow rate is not accurate.

气体流量传感器损坏更换即可。有时候是通过压差来计算流量的，这时候我们就要更换新的压差传感器。

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）设备漏气。

(c) Equipment leaks.

很多情况是器械密封圈老化而引起的。但也有设备机械减压阀漏气和电磁阀损坏的原因，这个比较容易判断出并对其进行修复。

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 that of a gas pressure sensor.

（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 of electrocoagulation and electrocautery system

（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 accessories.

（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, 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.".

动力、消融系统常见的故障

Common faults of 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 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 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.

冲洗吸引系统常见的故障

Common faults in the flushing suction system

（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 two-way pump in the equipment is aging, or the negative pressure bottle leaks.

（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 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.
