医用内窥镜腹腔镜常见故障分析排除

　　Analysis and elimination of common troubles of medical endoscope and laparoscope

　　故障一、图像干扰

　　Fault 1. Image interference

　　主要反阳在屏幕上出现水平状杂波，影响手术。

　　Horizontal clutter appeared on the screen, which affected the operation.

　　造成该故障有两种原因：一是手术过程中使用的电刀出现干扰，一般属于电磁干扰，是由视频传输线屏蔽不好所造成，跟换质量好的视频传输线故障方可排除。 二是干扰出现移动摄像头时，这种现象一般是摄像头内部链接线接触不良。摄像头连接线有数根信号线组成一束，机器长时间使用或保管不善的情况下会出现内部信号线折断，接触不良导致图像干扰。检查此连接线束，可分段或逐段扭动线束。找到大致部位，然后确定那根信号线出现断路，接续后方可排除。

　　There are two reasons for this failure: first, the interference of the electric knife used in the operation is generally electromagnetic interference, which is caused by the poor shielding of the video transmission line, and can be eliminated only after the failure of the video transmission line with good quality is replaced. Second, when the interference occurs to the mobile camera, this phenomenon is generally due to poor contact of the internal link line of the camera. The camera connecting line is composed of several signal lines. When the machine is used for a long time or stored improperly, the internal signal line will break, resulting in image interference due to poor contact. Check the connecting harness, and twist the harness in sections or sections. Find out the general position, and then make sure that the signal wire has an open circuit, which can be removed after connecting.
             

　　故障二、冷光源灯泡不亮

　　Fault 2. Cold light bulb does not work

　　造成灯泡不亮一般有两个原因：一是灯泡本身问题，更换新灯故障机可排除，不过光源灯泡使用寿命（时长）冷光源的面板上装有计时器，并且设置参数一般为500h内不会报警，超过500h后计数器出现闪烁提示，但特触情况例外。当然也不外乎其他电路出现问题时灯泡不亮的情况。宰割该灯泡老化程度严重时需要多次激发才能呢过发亮，这样有可能造成冷光高压模块过载损坏。在维修过程中、合理更换灯泡既可减少成本也可以减少机器的故障率；如更换灯泡后灯不亮、可以判定故障处在高压模块有损坏的可能，只能更换高压模块故障方可排除。

　　There are generally two reasons for the bulb not to light up: first, the bulb itself is a problem, which can be eliminated by replacing a new lamp fault machine, but the service life of the light source bulb (length of time) the panel of the cold light source is equipped with a timer, and the setting parameter is generally no alarm within 500h, after more than 500h, the counter flashes, but the special case is exceptional. Of course, it is no more than that when other circuits have problems, the bulb does not light up. When the aging degree of the light bulb is serious, it needs to be activated several times to be too bright, which may cause overload damage to the cold light high-voltage module. In the process of maintenance, reasonable replacement of the bulb can not only reduce the cost, but also reduce the failure rate of the machine. If the lamp does not light up after replacement of the bulb, it can be determined that the failure may be caused by the damage of the high-voltage module, and only the failure of the high-voltage module can be eliminated.

　　故障三、气腹机液体污染

　　Fault 3. Liquid pollution of pneumoperitoneum

　　当气腹机内进入液体污染后气腹机出现故障代码E32，此时机器死机不能工作。

　　When the pneumoperitoneum machine enters the liquid pollution, the pneumoperitoneum machine appears the fault code E32, at this time the machine crashes and cannot work.

　　这是由于气腹机内部管内存在液体，倒流会使机器不工作，排除方法是首先彻底排除及其内部的液体，然后用RS323蓝、、连接线、连接气腹机与电脑，用专用软件消除故障代码后气腹机可恢复正常。此故障出现时，为防止手术污染，机器立即锁死，手术不能正常进行，所以在使用中应极力避免。只要手术前彻底排干气腹管内液体、同时升高气腹机的放置高度，此故障就完全可以避免发生。

　　This is because there is liquid in the internal tube of the pneumoperitoneum machine, and backflow will make the machine not work. The elimination method is to completely eliminate the liquid inside the pneumoperitoneum machine first, then connect the pneumoperitoneum machine with the computer by rs323 blue, connecting wire, and connecting the pneumoperitoneum machine with the computer. After the fault code is eliminated by the special software, the pneumoperitoneum machine can be restored to normal. When this fault occurs, in order to prevent operation pollution, the machine is locked immediately, and the operation cannot be carried out normally, so it should be avoided in use. As long as the fluid in the pneumoperitoneum tube is drained completely before the operation, and the placement height of the pneumoperitoneum machine is raised at the same time, the failure can be completely avoided.
