隨著醫療技術發展，醫用內窺鏡在臨床廣泛應用，使用中常出現光源、氣腹、液體加壓等系統故障，掌握相應解決辦法可保障設備正常運行。

　　With the development of medical technology, medical endoscopes are widely used in clinical practice. System failures such as light source, pneumoperitoneum, and liquid pressurization often occur during use. Mastering corresponding solutions can ensure the normal operation of the equipment.

　　光源系統故障中，光線發暗多因燈泡接近使用壽命（氙光燈泡壽命約 500 小時），排除光柵遮擋后更換新燈泡即可，帶壽命計時裝置的設備更易判斷。開機燈泡不亮若非燈泡燒毀，多為高壓點火電路元件老化，注意不可用萬用表檢測脈沖高壓。

　　In the case of a malfunction in the light source system, dim light is often caused by the bulb approaching its service life (xenon light bulbs have a lifespan of about 500 hours). After eliminating grating obstruction, replacing the bulb with a new one is sufficient. Equipment with a lifespan timer is easier to determine. If the light bulb does not light up when turned on, it is mostly due to the aging of high-voltage ignition circuit components, and it is important not to use a multimeter to detect pulse high voltage.

　　人工氣腹系統故障需針對性處理：壓力顯示異常多是氣體壓力傳感器損壞，若為多組壓差傳感器，建議整體更換避免同組元件陸續失效；流量不準更換流量或壓差傳感器；設備漏氣常因密封圈老化、減壓閥或電磁閥損壞，較易判斷修復。

　　The malfunction of the artificial pneumoperitoneum system needs targeted treatment: abnormal pressure display is often caused by damaged gas pressure sensors. If it is multiple sets of differential pressure sensors, it is recommended to replace them as a whole to avoid the failure of components in the same set one after another; Do not replace flow or differential pressure sensors for flow; Equipment leakage is often caused by aging sealing rings, damage to pressure reducing valves or solenoid valves, which are easier to diagnose and repair.

　　液體加壓系統常見蠕動泵損壞、液體壓力傳感器故障（原理同氣體傳感器）及內部電路損壞，需對應更換部件或檢修電路。

　　Common damage to peristaltic pumps, liquid pressure sensors (based on the same principle as gas sensors), and internal circuits in liquid pressurization systems require corresponding replacement of components or maintenance of circuits.

　　電凝電切系統故障中，腳踏開關、負極板導線等配件易損，直接更換即可；電切、電凝及雙極故障，可根據現象維修或更換對應電路模塊。

　　In the case of faults in the electrocoagulation and cutting system, accessories such as foot switches and negative electrode wires are easily damaged and can be replaced directly; Electric cutting, electrocoagulation, and bipolar faults can be repaired or replaced with corresponding circuit modules according to the symptoms.

　　動力系統主要是刨削刀頭磨損和手柄內電機問題，電機更換受型號限制，需注重使用保護；消融系統多為刀頭損耗，設備故障常為電路問題，可從輸出部分排查。

　　The main issues with the power system are the wear of the planing blade and the motor inside the handle. The replacement of the motor is limited by the model, and attention should be paid to its protection during use; The ablation system is mostly caused by blade wear, and equipment failures are often circuit problems, which can be investigated from the output part.

　　沖洗吸引系統壓力或吸力不足，可能是雙向泵老化或負壓瓶漏氣；設備無法開機若因液體誤吸，清理干凈未損壞部件即可恢復。

　　Insufficient pressure or suction in the flushing suction system may be due to aging of the bidirectional pump or leakage of the negative pressure bottle; If the device cannot be turned on due to liquid aspiration, it can be restored by cleaning the undamaged parts.

　　為減少故障，建議設專用手術間，由專科護士操作保養，嚴格遵循術前檢查、術中排障、術后維護流程。設備故障優先采取應急維修，可解決約 85% 的中小故障。

　　To reduce malfunctions, it is recommended to set up a dedicated operating room, operated and maintained by specialized nurses, and strictly follow the procedures of preoperative examination, intraoperative troubleshooting, and postoperative maintenance. Priority should be given to emergency maintenance for equipment failures, which can solve about 85% of small and medium-sized faults.
