一、光源系统常见的故障

1、 Common faults in light source systems

1.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，这个问题就很容易解决。

1. Make it dark. Excluding the possibility of grating obstruction, it can be basically confirmed that the light bulb is approaching its service life and can be replaced with a new one. The service life of xenon light bulbs is generally designed to be 500 hours. If the light source system has a lifespan timer, this problem can be easily solved.

2.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。

2. The light bulb does not light up. If the cause of burning out the light bulb is ruled out, then 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. Note that a multimeter should not be used to check the pulse high voltage at this time.

二、人工气腹系统常见的故障

2、 Common faults of artificial pneumoperitoneum system

1.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。

1. Display is incorrect. This is mostly due to damage to gas pressure sensors. If the machine is designed with a set of multiple differential pressure sensors working simultaneously, usually when one sensor is aging or contaminated and cannot work, we need to replace all sensors in this set. Otherwise, only one sensor will be replaced, and the lifespan of other sensors in the same set will also be close to critical.

2.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。

2. Inaccurate. Replace the damaged gas flow sensor. Sometimes the flow rate is calculated based on the pressure difference, and in this case, we need to replace the pressure difference sensor with a new one.

3.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。

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

三、液体加压系统常见的故障

3、 Common faults in liquid pressurization systems

1.泵损坏。

1. The pump is damaged.

2.压力传感器损坏:原理基本与气体压力传感器相同。

2. Pressure sensor damage: The principle is basically the same as that of gas pressure sensors.

3.内部电路损坏。

3. Internal circuit damage.

4.切系统常见的故障

4. Common faults in the cutting system

5.配件损坏:脚踏开关，负极板导线，连接导线等常用的易损配件。

5. Damaged accessories: commonly used vulnerable accessories such as foot switches, negative electrode wires, and connecting wires.

6.在设备内部,部分都由不同的电路模块组成: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。

6. Inside the device, some parts are composed of different circuit modules: they can repair or replace the corresponding module circuits according to the fault symptoms they exhibit.

四、系统常见的故障

4、 Common system malfunctions

1.主要是刨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。

1. The main issues are the wear of the planing blade and the problem with the high-energy motor in the planing handle, and the replacement of the motor is selective, not every type of motor has replacement parts. Therefore, special attention should be paid to protection during disinfection and use.

2.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。

In surgical applications, the main issue with the system is the loss of the cutting edge. And equipment failures are mostly circuit failures, usually starting from the output part.

3.吸引系统常见故障

3. Common faults in the attraction system

4.压力或者吸力不足。设备中的双向泵老化,或者负压瓶漏气。

4. Insufficient pressure or suction. The bidirectional pump in the equipment is aging, or the negative pressure bottle is leaking.

5.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。

5. The device cannot be turned on, usually due to liquid entering the device. Clean up the mistakenly sucked liquid without burning out the relevant components.
