一、光源系統常見的故障

1、 Common faults in light source systems

1.發暗。排除了是光柵遮擋的原因外，基本可以肯定是燈泡接近使用壽命，更換新燈泡則可。氙光燈泡的使用壽命一般設計在500小時，如果光源系統有壽命計時裝置，這個問題就很容易解決。

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.燈泡不亮。如果排除了燒掉燈泡這個原因的話，那么問題常常就出在主機高壓點火電路部分，因為開機的時候機器會產生上萬伏特的脈沖高壓，元件會老化得特別快。注意此時不能用萬用表去檢查脈沖高壓。

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、人工氣腹系統常見的故障

2、 Common faults of artificial pneumoperitoneum system

1.顯示不正確。這多是氣體壓力傳感器損壞，如果機器設計有一組多個壓差壓力傳感器同時工作的，一般一個老化或者污染無法工作的時候，我們要把這組傳感器全部更換，否則只換其中一個，其他的同組的傳感器壽命也接近臨界了。

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.不準確。氣體流量傳感器損壞更換即可。有時候是通過壓差來計算流量的，這時候我們就要更換新的壓差傳感器。

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.漏氣。很多情況是器械密封圈老化而引起的。但也有設備機械減壓閥漏氣和電磁閥損壞的原因，這個比較容易判斷出并對其進行修復。

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、液體加壓系統常見的故障

3、 Common faults in liquid pressurization systems

1.泵損壞。

1. The pump is damaged.

2.壓力傳感器損壞:原理基本與氣體壓力傳感器相同。

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

3.內部電路損壞。

3. Internal circuit damage.

4.切系統常見的故障

4. Common faults in the cutting system

5.配件損壞:腳踏開關，負極板導線，連接導線等常用的易損配件。

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

6.在設備內部,部分都由不同的電路模塊組成: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。

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、系統常見的故障

4、 Common system malfunctions

1.主要是刨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。因此在消毒和使用過程中要分外注意保護。

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。

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.吸引系統常見故障

3. Common faults in the attraction system

4.壓力或者吸力不足。設備中的雙向泵老化,或者負壓瓶漏氣。

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

5.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。

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.
