（1）摄像显像系统常见的故障
(1) Common faults of camera imaging system
图像有干扰。一般是因为用
The image is disturbed. Usually because
电刀等高频设备的时候对线路产生干扰，这时候我们要检查的是摄像头与连接中的屏蔽线是否有接通。还有一种情况就是没有使用高频设备的时候也会出现干扰条纹，这时候是连接线信号线由于长期使用，屏蔽层磨损。需要看是摄像头的连接处出问题还是整条线体老化，前者需要重新焊接，而后者则需要更换连接导线了。目前更换原装进口的3m长的连接导线在10000RMB左右。所以使用过程中尽量避免导线在地上被仪器车或手术车碾过。
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）图像偏色。在白平衡后和排除其他配套设备的影响下都无法还原景物的颜色时，我们认为可能是由导线老化信号传递缺陷引起的，也可能是摄像头电路元件老化变质，又或者是由摄像头CCD老化引起。此时我们只需更换相应的配件则可。
(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）摄像主机的故障一般少有发生。如果发生的软件故障（程序故障）只能拿回厂家更换程序芯片了。 （2）影像记录系统常见的故障
(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）脚踏开关失灵。
(a) Foot switch failure.
（b）视屏连接线接触不良。
(b) Poor contact of video screen connecting wire.
（c）电脑硬件故障。
(c) Computer hardware failure.
（d）系统软件或图像采集软件故障。 这些都是比较简单的问题,这里不再展开讨论。
(d) System software or image acquisition software failure. These are relatively simple issues, which will not be discussed here.
（3）光源系统常见的故障
(3) Common faults of light source system
（a）光线发暗。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。

(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）开机灯泡不亮。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。
(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）人工气腹系统常见的故障
(4) Common faults of artificial pneumoperitoneum system
（a）压力显示不正确。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。
(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）流量不准确。气体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。
(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）设备漏气。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。
(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）液体加压系统常见的故障蠕动泵损坏。
(5) The common fault of liquid pressurization system is the damage of peristaltic pump.
（b）液体压力传感器损坏。其原理基本与气体压力传感器相同。
(b) The liquid pressure sensor is damaged. Its principle is basically the same as that of gas pressure sensor.
（c）设备内部电路损坏。
(c) The internal circuit of the equipment is damaged.
（6）电凝电切系统常见的故障
(6) Common faults of electric coagulation and electric cutting system
（a）设备配件损坏。如脚踏开关，负极板导线，连接导线等常用的易损配件。
(a) Equipment accessories are damaged. Such as foot switch, negative plate, conductor, connecting conductor and other common vulnerable accessories.
（b）电切、电凝，双极故障。在设备内部，这些部分都由不同的电路模块组成。我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。
(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）动力、消融系统常见的故障
(7) Common faults of power and ablation system
（a）动力系统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。因此在和使用过程中要分外注意保护。
(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。
(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）冲洗吸引系统常见故障 （a）压力或者吸力不足。设备中的双向泵老化,或者负压瓶漏气。
(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）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。
(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.
