內窺鏡作為醫療與工業檢測領域的關鍵設備，其精密光學系統與機械結構對維修工具提出嚴苛要求。維修過程需結合電子檢測、光學調試及機械校準等多學科技術，使用專業化工具保障設備恢復原始性能。以下從功能維度解析內窺鏡維修的核心工具及其應用場景。

　　As a key equipment in the fields of medical and industrial testing, endoscopes have strict requirements for maintenance tools due to their precise optical systems and mechanical structures. The maintenance process requires a combination of multidisciplinary technologies such as electronic testing, optical debugging, and mechanical calibration, and the use of specialized tools to ensure that the equipment is restored to its original performance. The following analyzes the core tools and their application scenarios for endoscopic maintenance from a functional perspective.

　　一、光學系統檢修工具

　　1、 Optical system maintenance tool

　　冷光源測試儀：

　　Cold light source tester:

　　用于檢測氙燈或LED光源的色溫、照度及光譜分布。設備通過積分球采集光線數據，可診斷光源老化程度，當色溫偏差超過±500K或照度衰減至初始值70%以下時，需更換燈組模塊。

　　Used to detect the color temperature, illuminance, and spectral distribution of xenon lamps or LED light sources. The device collects light data through an integrating sphere to diagnose the degree of aging of the light source. When the color temperature deviation exceeds ± 500K or the illuminance attenuates to below 70% of the initial value, the lamp module needs to be replaced.

　　光纖導光束檢測儀：

　　Fiber optic guided beam detector:

　　采用光功率計測量導光束傳輸效率，正常值應≥85%。對于彎曲半徑過小或受壓變形的導光束，可通過顯微鏡觀察纖芯斷裂情況，斷裂點超過3處即需整體更換。

　　Using an optical power meter to measure the transmission efficiency of the guide beam, the normal value should be ≥ 85%. For guide beams with a bending radius that is too small or deformed under pressure, the fiber core fracture can be observed under a microscope, and if there are more than 3 fracture points, they need to be replaced as a whole.

　　鏡面擦拭套裝：

　　Mirror wiping kit:

　　包含異丙醇清洗劑、無塵棉簽與鏡頭紙，用于清除物鏡、目鏡表面的油污與劃痕。對于頑固污漬，需使用CO?雪清洗機進行非接觸式清潔，避免損傷鍍膜層。

　　Contains isopropanol cleaning agent, dust-free cotton swabs, and lens paper, used to remove oil stains and scratches on the surface of objective lenses and eyepieces. For stubborn stains, a CO snow cleaner should be used for non-contact cleaning to avoid damaging the coating layer.

　　二、電子系統診斷設備

　　2、 Electronic system diagnostic equipment

　　示波器與邏輯分析儀：

　　Oscilloscope and Logic Analyzer:

　　聯合使用可捕獲圖像傳感器輸出的LVDS信號波形，通過眼圖分析判斷信號完整性。當上升沿時間超過1ns或噪聲容限低于200mV時，需檢查柔性線路板焊接質量。

　　Combine the captured LVDS signal waveform output by the image sensor and determine signal integrity through eye diagram analysis. When the rising edge time exceeds 1ns or the noise tolerance is below 200mV, the welding quality of the flexible circuit board needs to be checked.

　　CCD/CMOS測試卡：

　　CCD/CMOS test card:

　　生成標準分辨率圖卡與灰階卡，配合亮度計檢測成像單元的MTF（調制傳遞函數）。若中心區域MTF@50lp/mm低于30%，需重新調整傳感器與鏡頭的對焦精度。

　　Generate standard resolution image cards and grayscale cards, and use a brightness meter to detect the MTF (Modulation Transfer Function) of the imaging unit. If the central area MTF@50lp /If the mm is less than 30%, the focusing accuracy of the sensor and lens needs to be readjusted.

　　靜電放電模擬器：

　　Electrostatic discharge simulator:

　　模擬人體8kV接觸放電與15kV空氣放電場景，驗證主機電路的ESD防護能力。關鍵接口需通過IEC 61000-4-2四級測試標準，確保醫療環境下的使用安全性。

　　Simulate human 8kV contact discharge and 15kV air discharge scenarios to verify the ESD protection capability of the host circuit. Key interfaces must pass the IEC 61000-4-2 Level 4 testing standard to ensure safety in medical environments.

　　三、機械結構維修器具

　　3、 Mechanical structure maintenance equipment

　　內窺鏡角度調節器：

　　Endoscope angle adjuster:

　　采用六軸力傳感器與伺服電機系統，可精確復現彎曲部的蛇形運動。通過捕捉每個關節的扭矩曲線，診斷鋼絲繩斷裂或滑輪磨損故障，角度偏差超過5°即需維修。

　　By using a six axis force sensor and servo motor system, the serpentine motion of the bending part can be accurately reproduced. By capturing the torque curve of each joint, diagnose faults such as wire rope breakage or pulley wear, and repair if the angle deviation exceeds 5 °.

　　激光對中儀：

　　Laser centering device:

　　用于校準插入管的直線度，測量精度達0.01mm/m。對于直徑8mm以上的工業內窺鏡，彎曲段直線度誤差需控制在0.5mm以內，避免檢測時產生視覺盲區。

　　Used to calibrate the straightness of the insertion tube, with a measurement accuracy of 0.01mm/m. For industrial endoscopes with a diameter of over 8mm, the straightness error of the curved section should be controlled within 0.5mm to avoid visual blind spots during inspection.

　　密封性測試裝置：

　　Sealing testing device:

　　通過正壓（50kPa）與負壓（-30kPa）雙向檢測，確認先端部防水等級。使用熒光檢漏劑浸泡后，UV燈照射下無泄漏點方可重新封裝，確保設備滿足IP67防護要求。

　　Confirm the waterproof level of the tip by bidirectional detection of positive pressure (50kPa) and negative pressure (-30kPa). After soaking in fluorescent leak detector, the equipment can only be repackaged after there are no leakage points under UV light irradiation to ensure that it meets IP67 protection requirements.

　　四、專用校準與軟件工具

　　4、 Specialized calibration and software tools

　　幾何畸變校正卡：

　　Provide 24 standard color blocks, collect data through a spectrometer to generate a calibration matrix. In a 4000K color temperature environment, the color temperature error should be less than ± 200K to ensure consistency in color reproduction under different light source conditions.

　　固件燒錄器：
