（1）光源系統常見的故障

(1) Common faults in light source systems

（a）光線發暗。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。

(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）開機燈泡不亮。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。

(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）人工氣腹系統常見的故障

(2) Common malfunctions of artificial pneumoperitoneum systems

（a）壓力顯示不正確。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。

(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。

(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）設備漏氣。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。

(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）液體加壓系統常見的故障

(3) Common faults in liquid pressurization systems

（a）蠕動泵損壞。

(a) The peristaltic pump is damaged.

（b）液體壓力傳感器損壞。其原理基本與氣體壓力傳感器相同。

(b) The liquid pressure sensor is damaged. Its principle is basically the same as gas pressure sensors.

（c）設備內部電路損壞。

(c) The internal circuit of the equipment is damaged.

（4）電凝電切系統常見的故障

(4) Common faults in electrocoagulation and electrocautery systems

（a）設備配件損壞。如腳踏開關，負極板導線，連接導線等常用的易損配件。

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

（b）電切、電凝，雙極故障。在設備內部，這些部分都由不同的電路模塊組成。我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。

(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.
