醫(yī)用內(nèi)窺鏡腹腔鏡常見故障分析排除

　　Analysis and elimination of common troubles of medical endoscope and laparoscope

　　故障一、圖像干擾

　　Fault 1. Image interference

　　主要反陽在屏幕上出現(xiàn)水平狀雜波，影響手術(shù)。

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

　　造成該故障有兩種原因：一是手術(shù)過程中使用的電刀出現(xiàn)干擾，一般屬于電磁干擾，是由視頻傳輸線屏蔽不好所造成，跟換質(zhì)量好的視頻傳輸線故障方可排除。 二是干擾出現(xiàn)移動攝像頭時，這種現(xiàn)象一般是攝像頭內(nèi)部鏈接線接觸不良。攝像頭連接線有數(shù)根信號線組成一束，機器長時間使用或保管不善的情況下會出現(xiàn)內(nèi)部信號線折斷，接觸不良導致圖像干擾。檢查此連接線束，可分段或逐段扭動線束。找到大致部位，然后確定那根信號線出現(xiàn)斷路，接續(xù)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、冷光源燈泡不亮

　　Fault 2. Cold light bulb does not work

　　造成燈泡不亮一般有兩個原因：一是燈泡本身問題，更換新燈故障機可排除，不過光源燈泡使用壽命（時長）冷光源的面板上裝有計時器，并且設置參數(shù)一般為500h內(nèi)不會報警，超過500h后計數(shù)器出現(xiàn)閃爍提示，但特觸情況例外。當然也不外乎其他電路出現(xiàn)問題時燈泡不亮的情況。宰割該燈泡老化程度嚴重時需要多次激發(fā)才能呢過發(fā)亮，這樣有可能造成冷光高壓模塊過載損壞。在維修過程中、合理更換燈泡既可減少成本也可以減少機器的故障率；如更換燈泡后燈不亮、可以判定故障處在高壓模塊有損壞的可能，只能更換高壓模塊故障方可排除。

　　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、氣腹機液體污染

　　Fault 3. Liquid pollution of pneumoperitoneum

　　當氣腹機內(nèi)進入液體污染后氣腹機出現(xiàn)故障代碼E32，此時機器死機不能工作。

　　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.

　　這是由于氣腹機內(nèi)部管內(nèi)存在液體，倒流會使機器不工作，排除方法是首先徹底排除及其內(nèi)部的液體，然后用RS323藍、、連接線、連接氣腹機與電腦，用專用軟件消除故障代碼后氣腹機可恢復正常。此故障出現(xiàn)時，為防止手術(shù)污染，機器立即鎖死，手術(shù)不能正常進行，所以在使用中應極力避免。只要手術(shù)前徹底排干氣腹管內(nèi)液體、同時升高氣腹機的放置高度，此故障就完全可以避免發(fā)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.
