（1）光源系统常见的故障

(1) Common faults in light source systems

（a）光线发暗。排除了是光栅遮挡的原因外，基本可以肯定是灯泡接近使用寿命，更换新灯泡则可。氙光灯泡的使用寿命一般设计在500小时，如果光源系统有寿命计时装置，这个问题就很容易。

(a) The light is dim. Excluding the possibility of grating obstruction, it is generally certain that the bulb is nearing its lifespan, and replacing it with a new bulb is sufficient. The service life of xenon light bulbs is generally designed to be 500 hours. If the light source system has a lifespan timer device, this problem can be easily solved.

（b）开机灯泡不亮。如果排除了烧掉灯泡这个原因的话，那么问题常常就出在主机高压点火电路部分，因为开机的时候机器会产生上万伏特的脉冲高压，元件会老化得特别快。注意此时不能用万用表去检查脉冲高压。

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

（2）人工气腹系统常见的故障

(2) Common malfunctions of artificial pneumoperitoneum systems

（a）压力显示不正确。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。

(a) The pressure display is incorrect. This is mostly due to damage to gas pressure sensors. If the machine is designed with a group of multiple differential pressure sensors working simultaneously, usually when one sensor is aging 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 lifespan of other sensors in the same group will also be close to the critical point.

（b）流量不准确。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。

(b) Inaccurate traffic. Replace the damaged gas flow sensor. Sometimes the flow rate is calculated by pressure difference, and at this time we need to replace it with a new pressure difference sensor.

（c）设备漏气。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。

(c) Equipment leaks air. Many cases are caused by aging of instrument sealing rings. But there are also reasons for mechanical pressure reducing valve leakage and electromagnetic valve damage, which are relatively easy to identify and repair.

（3）液体加压系统常见的故障

(3) 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 equipment is damaged.

（4）电凝电切系统常见的故障

(4) 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. Commonly used vulnerable accessories such as foot switches, negative electrode wires, and connecting wires.

（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 fault. Internally, these parts are composed of different circuit modules. We can repair or replace the corresponding module circuit based on the symptoms of the malfunction.
