在現代醫療領域，內窺鏡設備是不可或缺的診斷與治療工具，廣泛應用于各類微創手術、無創檢查等場景，像腹腔鏡手術、胃腸鏡檢查等。其能夠深入人體內部，為醫生提供直觀、清晰的圖像，幫助精準判斷病情。不過，由于頻繁使用以及設備本身的精密性，內窺鏡設備難免會出現故障，此時有效的維修就顯得尤為關鍵。

In the modern medical field, endoscopic equipment is an indispensable diagnostic and therapeutic tool, widely used in various minimally invasive surgeries, non-invasive examinations, and other scenarios, such as laparoscopic surgery, gastrointestinal endoscopy, etc. It can penetrate deep into the human body, providing doctors with intuitive and clear images to help accurately diagnose the condition. However, due to frequent use and the precision of the equipment itself, endoscopic devices are inevitably prone to malfunctions, making effective maintenance particularly crucial.

常見故障類型

Common types of faults

圖像顯示故障

Image display malfunction

圖像異常顯示：監視器輸出圖像時，出現水平或垂直彩色條紋干擾，又或是彩色雪花狀閃爍。這大概率是高清攝像頭手柄與電纜連接點因反復彎曲、拉扯導致電纜損壞，亦或是電纜線與主機相連插頭老化腐蝕，接觸不良。此外，手術室內如電刀這類高頻高電流設備產生的信號干擾，尤其是電凝棒、電刀筆等器械漏電時，也會引發此類問題。

Abnormal image display: When the monitor outputs an image, there may be horizontal or vertical color stripe interference, or color snowflake like flickering. This is most likely due to repeated bending and pulling at the connection point between the high-definition camera handle and the cable, resulting in cable damage, or aging and corrosion of the plug connecting the cable to the host, leading to poor contact. In addition, signal interference generated by high-frequency and high current equipment such as electric knives in the operating room, especially when electric coagulation rods, electric knives, pens and other instruments leak electricity, can also cause such problems.

監視器無圖像：一是監視器黑屏，既無圖像也無內窺鏡視野框，可能是監視器本身故障，像外置 12V 直流電源適配器未正常供電，或者是信號輸入故障；二是監視器有內窺鏡視野框，卻無圖像，極有可能是內窺鏡自身問題，比如電子軟鏡漏水致使 CCD 底座腐蝕、損壞，硬鏡彎折變形、物鏡碎裂等 。

Monitor without image: Firstly, the monitor has a black screen, without any image or endoscope field of view frame, which may be due to a malfunction of the monitor itself, such as an external 12V DC power adapter not supplying power properly, or a signal input failure; The second issue is that the monitor has an endoscope field of view frame but no image, which is highly likely due to problems with the endoscope itself, such as corrosion or damage to the CCD base caused by electronic soft lens leakage, bending and deformation of the hard lens, and breakage of the objective lens.

內窺鏡故障

Endoscope malfunction

硬管內窺鏡故障：圖像暗淡可能是冷光源燈泡使用時長超 500h、光纖斷裂有暗點，又或是內窺鏡導光束接頭污染；圖像模糊多因寶石保護玻璃磨損老化、物鏡密封性遭破壞；圖像不全通常是內部柱狀透鏡斷裂、崩邊；鏡體明顯變形、缺損則是因操作人員使用鈥激光、高頻電刀等設備時打傷物鏡，操作鏡子與鞘管連接不當，以及消毒滅菌時撞擊、摔碰造成 。

Hard tube endoscope malfunction: The dim image may be due to the use of a cold light bulb for more than 500 hours, fiber breakage with dark spots, or contamination of the endoscope guide beam connector; Image blurring is often caused by the wear and aging of gemstone protective glass, as well as damage to the sealing of the objective lens; Incomplete images are usually caused by internal cylindrical lens fractures or broken edges; The obvious deformation and damage of the mirror body are caused by the operator injuring the objective lens when using holmium laser, high-frequency electric knife and other equipment, improper connection between the mirror and the sheath tube, as well as impact and falling during disinfection and sterilization.

電子軟鏡故障：漏水最為常見，泄漏點可能在彎曲橡皮、插入管、鉗道管、角度旋鈕處、按鈕等部位；水氣堵塞多是先端水氣噴嘴被污物堵塞；角鈕虛位并彎曲角度不足是由于角度鋼絲老化變松 。

Electronic soft mirror malfunction: Water leakage is the most common, and the leakage point may be in the bent rubber, insertion tube, clamp tube, angle knob, button and other parts; Water vapor blockage is often caused by the blockage of the front water vapor nozzle by dirt; The virtual position and insufficient bending angle of the corner knob are due to the aging and loosening of the angle steel wire.

其他配套設備和器械故障

Other supporting equipment and instruments malfunction

例如送氣送水裝置故障，像送氣正常但送不出水，可能是送水儲水杯蓋未擰緊、連接水管漏氣、打氣泵或氣泵單向閥問題，甚至是單向閥到通氣接口處的軟管破裂。又比如光源故障，導致光線不足或不穩定，影響圖像采集 。

For example, if the air and water delivery device malfunctions, such as normal air delivery but unable to deliver water, it may be due to the loose lid of the water storage cup, air leakage in the connecting water pipe, problems with the air pump or one-way valve of the air pump, or even a broken hose from the one-way valve to the ventilation interface. For example, a light source malfunction can result in insufficient or unstable light, affecting image acquisition.
