（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.

（5）動力、消融系統常見的故障

(5) Common faults in power and ablation systems

（a）動力系統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。

(a) The power system is mainly due to the wear of the planer blade and problems with the high-energy motor in the planer 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.

（b）消融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。

(b) The ablation system is mainly used in surgical applications due to the loss of the blade. And equipment failures are mostly circuit failures, usually starting from the output part.

（6）沖洗吸引系統常見故障

(6) Common faults in flushing and suction systems

（a）壓力或者吸力不足。設備中的雙向泵老化,或者負壓瓶漏氣。

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

（b）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。

(b) The device cannot be turned on, usually due to liquid entering the device. Clean up the mistakenly aspirated liquid without burning the relevant components.

為了盡可能減少設備故障的發生，應設立腹腔鏡專用手術間，以減少儀器的搬動及損壞，并指派腔鏡專科護士使用和保養，腔鏡專科護士應全面熟悉儀器性能與結構特點及正確的使用方法，嚴格執行操作規程，抓好手術前檢查、術中故障排除、術后及時維護保養3個環節。如果是設備出問題，首先是采取應急維修，因為這樣能解決占故障85%左右的中小故障。

In order to minimize the occurrence of equipment failures, a dedicated laparoscopic operating room should be established to reduce the movement and damage of instruments, and specialized laparoscopic nurses should be assigned to use and maintain them. Specialized laparoscopic nurses should be fully familiar with the performance and structural characteristics of instruments and the correct usage methods, strictly follow operating procedures, and focus on three aspects: preoperative inspection, intraoperative troubleshooting, and timely postoperative maintenance. If there is a problem with the equipment, the first step is to take emergency maintenance, as this can solve about 85% of small and medium-sized faults.
