在內(nèi)窺鏡檢查與微創(chuàng)手術(shù)中，光源如同 “黑暗中的火炬”，為醫(yī)生的精準(zhǔn)操作提供清晰視野。一旦光源出現(xiàn)故障，檢查與手術(shù)進(jìn)程都會(huì)受到影響。想要讓內(nèi)窺鏡光源 “重見光明”，需要對(duì)故障原因抽絲剝繭，并掌握科學(xué)的修復(fù)方法，才能讓其恢復(fù)往日的明亮。

　　In endoscopic examination and minimally invasive surgery, the light source is like a "torch in the dark", providing a clear view for the doctor's precise operation. Once the light source malfunctions, both the inspection and surgical process will be affected. To restore the brightness of the endoscope light source, it is necessary to thoroughly investigate the cause of the malfunction and master scientific repair methods in order to restore its former brightness.

　　診斷故障：找準(zhǔn)光源 “癥結(jié)”

　　Diagnosing faults: Identifying the root cause of the light source

　　修復(fù)光源的第一步是準(zhǔn)確判斷故障原因。常見的光源問題包括亮度不足、閃爍、完全不亮等。若光源亮度逐漸減弱，可能是燈泡老化導(dǎo)致。隨著使用時(shí)間增加，燈泡的燈絲會(huì)逐漸損耗，發(fā)光效率下降。而光源閃爍，大概率是電路接觸不良引起，比如電源線松動(dòng)、接頭氧化，或是電路板上的焊點(diǎn)虛焊。要是光源完全不亮，除了燈泡燒毀，還可能是電源供應(yīng)系統(tǒng)故障，像變壓器損壞、保險(xiǎn)絲熔斷，亦或是控制光源的驅(qū)動(dòng)電路出現(xiàn)問題。通過細(xì)致觀察光源表現(xiàn)，結(jié)合專業(yè)工具檢測，如使用萬用表測量電路通斷與電壓，才能精準(zhǔn)定位故障點(diǎn)。

　　The first step in repairing a light source is to accurately determine the cause of the malfunction. Common light source issues include insufficient brightness, flickering, and complete lack of illumination. If the brightness of the light source gradually decreases, it may be caused by the aging of the light bulb. As the usage time increases, the filament of the light bulb will gradually wear out and the luminous efficiency will decrease. And the flickering of the light source is most likely caused by poor circuit contact, such as loose power lines, oxidized connectors, or virtual soldering of solder joints on the circuit board. If the light source does not light up at all, besides the bulb burning out, it may also be a fault in the power supply system, such as a damaged transformer, blown fuse, or a problem with the driving circuit that controls the light source. By carefully observing the performance of the light source and combining it with professional tools for detection, such as using a multimeter to measure circuit continuity and voltage, the fault point can be accurately located.

　　燈泡更換：為光源注入 “新活力”

　　Light bulb replacement: injecting "new vitality" into the light source

　　當(dāng)確定是燈泡故障時(shí)，更換燈泡是直接有效的解決辦法。更換前，務(wù)必先關(guān)閉光源設(shè)備并斷開電源，等待燈泡冷卻，避免燙傷。不同類型的內(nèi)窺鏡光源，燈泡規(guī)格與安裝方式有所差異。一些光源的燈泡安裝在獨(dú)立的燈座內(nèi)，需擰下固定螺絲，小心拔出舊燈泡，注意不要觸碰燈泡玻璃表面，因?yàn)槭稚系挠椭瑫?huì)影響燈泡壽命和發(fā)光效果。安裝新燈泡時(shí)，將其準(zhǔn)確插入燈座，確保接觸良好，再擰緊螺絲固定。更換后，接通電源測試，若光源恢復(fù)正常亮度且無閃爍，說明更換成功。

　　When it is determined that it is a bulb malfunction, replacing the bulb is a direct and effective solution. Before replacing, be sure to turn off the light source device and disconnect the power supply, wait for the light bulb to cool down, and avoid burns. Different types of endoscopic light sources have differences in bulb specifications and installation methods. Some light source bulbs are installed in separate lamp sockets, and the fixing screws need to be unscrewed. Carefully remove the old bulb and be careful not to touch the glass surface of the bulb, as the grease on your hands can affect the lifespan and luminous effect of the bulb. When installing a new light bulb, insert it accurately into the lamp holder to ensure good contact, and then tighten the screws to secure it. After replacement, turn on the power for testing. If the light source returns to normal brightness without flickering, it indicates successful replacement.

　　電路檢修：疏通光源的 “電力脈絡(luò)”

　　Circuit maintenance: unclogging the "power network" of the light source

　　針對(duì)電路問題，需要逐步排查檢修。先檢查電源線和接頭，查看是否有破損、斷裂，若發(fā)現(xiàn)外皮破損，可使用絕緣膠帶包扎；對(duì)于氧化的接頭，用砂紙輕輕打磨，去除氧化層，恢復(fù)良好的導(dǎo)電性能。若問題出在電路板，需借助放大鏡仔細(xì)觀察焊點(diǎn)，尋找虛焊、脫焊的部位。使用電烙鐵對(duì)虛焊點(diǎn)進(jìn)行補(bǔ)焊，操作時(shí)要控制好溫度和焊接時(shí)間，避免燙壞電路板。對(duì)于損壞的電子元件，如電容、電阻等，要準(zhǔn)確識(shí)別其規(guī)格型號(hào)，更換上新的元件。在整個(gè)電路檢修過程中，每完成一步操作都要進(jìn)行通電測試，確保故障逐步排除。

　　For circuit issues, it is necessary to gradually troubleshoot and repair them. First, check the power cord and connectors for any damage or breakage. If the outer skin is found to be damaged, it can be wrapped with insulating tape; For oxidized joints, gently sand them with sandpaper to remove the oxide layer and restore good conductivity. If the problem lies on the circuit board, it is necessary to carefully observe the solder joints with a magnifying glass and search for areas of virtual soldering or detachment. Use an electric soldering iron to repair solder joints, and control the temperature and soldering time during the operation to avoid damaging the circuit board. For damaged electronic components such as capacitors, resistors, etc., it is necessary to accurately identify their specifications and replace them with new components. During the entire circuit maintenance process, a power on test must be conducted for each completed step to ensure that the fault is gradually eliminated.

　　電源系統(tǒng)維護(hù)：穩(wěn)固光源的 “能量根基”

　　Power system maintenance: stabilizing the "energy foundation" of the light source

　　電源供應(yīng)系統(tǒng)是光源穩(wěn)定工作的基礎(chǔ)。若變壓器出現(xiàn)故障，比如繞組短路、斷路，通常需要專業(yè)人員進(jìn)行維修或更換。保險(xiǎn)絲熔斷時(shí)，要查明熔斷原因，排除電路過載或短路故障后，再更換相同規(guī)格的保險(xiǎn)絲。此外，定期對(duì)電源系統(tǒng)進(jìn)行清潔保養(yǎng)，清除灰塵和雜物，防止因積塵導(dǎo)致電路短路。檢查電源模塊的散熱風(fēng)扇是否正常運(yùn)轉(zhuǎn)，若風(fēng)扇停轉(zhuǎn)或轉(zhuǎn)速異常，會(huì)影響電源模塊的散熱，進(jìn)而導(dǎo)致性能下降甚至損壞，需及時(shí)修復(fù)或更換風(fēng)扇。

　　The power supply system is the foundation for stable operation of the light source. If a transformer malfunctions, such as winding short circuit or open circuit, it usually requires professional personnel to repair or replace it. When a fuse blows, it is necessary to identify the cause of the blow, eliminate circuit overload or short circuit faults, and then replace the fuse with the same specification. In addition, regularly clean and maintain the power system, remove dust and debris, and prevent circuit short circuits caused by dust accumulation. Check if the cooling fan of the power module is running normally. If the fan stops running or has abnormal speed, it will affect the cooling of the power module, leading to performance degradation or even damage. It is necessary to repair or replace the fan in a timely manner.

　　專業(yè)校準(zhǔn)：讓光源 “精準(zhǔn)發(fā)力”

　　Professional calibration: enabling the light source to exert precise power

　　修復(fù)后的光源，還需進(jìn)行專業(yè)校準(zhǔn)，確保其發(fā)光強(qiáng)度、色溫等參數(shù)符合標(biāo)準(zhǔn)。使用專業(yè)的光學(xué)檢測設(shè)備，對(duì)光源的各項(xiàng)指標(biāo)進(jìn)行測量，根據(jù)測量結(jié)果調(diào)整光源的相關(guān)設(shè)置。例如，通過調(diào)節(jié)光源的調(diào)光旋鈕或控制軟件，將亮度調(diào)整到合適范圍，使色溫達(dá)到內(nèi)窺鏡檢查所需的標(biāo)準(zhǔn)，保證成像清晰、色彩還原準(zhǔn)確。

　　The repaired light source needs to undergo professional calibration to ensure that its luminous intensity, color temperature, and other parameters meet the standards. Use professional optical detection equipment to measure various indicators of the light source, and adjust the relevant settings of the light source based on the measurement results. For example, by adjusting the dimming knob or control software of the light source, the brightness can be adjusted to a suitable range to achieve the color temperature required for endoscopic examination, ensuring clear imaging and accurate color reproduction.

　　內(nèi)窺鏡光源的修復(fù)是一項(xiàng)需要耐心與專業(yè)技能的工作。從故障診斷到具體修復(fù)，再到最后的校準(zhǔn)，每一個(gè)環(huán)節(jié)都至關(guān)重要。掌握這些修復(fù)方法，能夠及時(shí)解決光源故障，保障內(nèi)窺鏡設(shè)備的正常使用，為醫(yī)療診斷和手術(shù)操作提供可靠的照明支持。

　　The repair of endoscopic light sources requires patience and professional skills. From fault diagnosis to specific repair, and finally calibration, every step is crucial. Mastering these repair methods can promptly solve light source failures, ensure the normal use of endoscopic equipment, and provide reliable lighting support for medical diagnosis and surgical operations.
