（1）攝像顯像系統常見的故障
(1) Common faults of camera imaging system
圖像有干擾。一般是因為用
The image is disturbed. Usually because
電刀等高頻設備的時候對線路產生干擾，這時候我們要檢查的是攝像頭與連接中的屏蔽線是否有接通。還有一種情況就是沒有使用高頻設備的時候也會出現干擾條紋，這時候是連接線信號線由于長期使用，屏蔽層磨損。需要看是攝像頭的連接處出問題還是整條線體老化，前者需要重新焊接，而后者則需要更換連接導線了。目前更換原裝進口的3m長的連接導線在10000RMB左右。所以使用過程中盡量避免導線在地上被儀器車或手術車碾過。
Electric knife and other high-frequency equipment interfere with the line. At this time, we need to check whether the camera is connected with the shielding wire in connection. Another situation is that interference stripes will appear when high-frequency equipment is not used. At this time, the shielding layer of the connecting line and signal line is worn due to long-term use. It depends on whether there is a problem at the connection of the camera or the whole line is aging. The former needs to be re welded, while the latter needs to replace the connecting wire. At present, the price of replacing the original imported 3M long connecting wire is about 10000 RMB. Therefore, during use, try to avoid the wire being run over by the instrument vehicle or surgical vehicle on the ground.
（b）圖像偏色。在白平衡后和排除其他配套設備的影響下都無法還原景物的顏色時，我們認為可能是由導線老化信號傳遞缺陷引起的，也可能是攝像頭電路元件老化變質，又或者是由攝像頭CCD老化引起。此時我們只需更換相應的配件則可。
(b) Image color deviation. When the color of the scene cannot be restored after white balance and excluding the influence of other supporting equipment, we think it may be caused by wire aging, signal transmission defects, aging and deterioration of camera circuit elements, or aging of camera CCD. At this time, we only need to replace the corresponding accessories.
（c）攝像主機的故障一般少有發生。如果發生的軟件故障（程序故障）只能拿回廠家更換程序芯片了。 （2）影像記錄系統常見的故障
(c) The failure of camera host generally rarely occurs. In case of software failure (program failure), the manufacturer can only replace the program chip. (2) Common faults of image recording system
（a）腳踏開關失靈。
(a) Foot switch failure.
（b）視屏連接線接觸不良。
(b) Poor contact of video screen connecting wire.
（c）電腦硬件故障。
(c) Computer hardware failure.
（d）系統軟件或圖像采集軟件故障。 這些都是比較簡單的問題,這里不再展開討論。
(d) System software or image acquisition software failure. These are relatively simple issues, which will not be discussed here.
（3）光源系統常見的故障
(3) Common faults of light source system
（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。

(a) The light darkened. Excluding the reason that the grating is blocked, it is basically certain that the bulb is close to its service life, and it can be replaced with a new bulb. The service life of xenon light bulb is generally designed at 500 hours. If the light source system has a life timer, 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 power on bulb does not light up. If the reason of burning the bulb is eliminated, the problem often lies in the high-voltage ignition circuit of the host, because the machine will produce tens of thousands of volts of pulse high voltage when starting up, and the components will age very fast. Note that the pulse high voltage cannot be checked with a multimeter at this time.
（4）人工氣腹系統常見的故障
(4) Common faults of artificial pneumoperitoneum system
（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 the damage of gas pressure sensors. If the machine is designed to have a group of multiple differential pressure sensors working at the same time, generally when an aging or pollution can not work, we should replace all the sensors in this group, otherwise only one of them will be replaced, and the service life of other sensors in the same group will be close to the critical point.
（b）流量不準確。氣體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) The flow is not accurate. If the gas sensor is damaged, replace it. Sometimes the flow is calculated by differential pressure. At this time, we need to replace the differential pressure 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) The equipment leaks. Many cases are caused by the aging of the sealing ring of the instrument. However, there are also reasons for air leakage of mechanical pressure reducing valve and damage of solenoid valve, which is easier to judge and repair.
（5）液體加壓系統常見的故障蠕動泵損壞。
(5) The common fault of liquid pressurization system is the damage of peristaltic pump.
（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 that of gas pressure sensor.
（c）設備內部電路損壞。
(c) The internal circuit of the equipment is damaged.
（6）電凝電切系統常見的故障
(6) Common faults of electric coagulation and electric cutting system
（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) Equipment accessories are damaged. Such as foot switch, negative plate, conductor, connecting conductor and other common vulnerable accessories.
（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, electric coagulation, bipolar fault. Inside the equipment, these parts are composed of different circuit modules. We can repair or replace the corresponding module circuit according to the fault phenomenon.
（7）動力、消融系統常見的故障
(7) Common faults of power and ablation system
（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 planing cutter head and the problems of the high-energy motor in the planing handle. The replacement of the motor is selective, and not every 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) Ablation system is mainly the loss of cutter head in surgical application. Most equipment faults are circuit faults, which generally start from the output part.
（8）沖洗吸引系統常見故障 （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。
(8) Common faults of flushing suction system (a) insufficient pressure or suction. The two-way pump in the equipment is aging, or the negative pressure bottle leaks.
（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 equipment cannot be started. Generally, most of the liquid enters the equipment. It is OK to clean the wrongly sucked liquid without burning the relevant parts.
