一、故障診斷?

1、 Fault diagnosis

當(dāng)腹腔鏡出現(xiàn)故障送至維修中心，專業(yè)技術(shù)人員首先會與使用科室進(jìn)行詳細(xì)溝通，了解故障發(fā)生的具體情形，如是否在手術(shù)過程中突然黑屏、圖像是否模糊、鏡頭是否存在霧氣等。隨后，運(yùn)用專業(yè)檢測設(shè)備對腹腔鏡進(jìn)行全面檢查，包括光學(xué)系統(tǒng)、電氣系統(tǒng)、機(jī)械結(jié)構(gòu)等。例如，使用專用的圖像測試卡檢測鏡頭的成像質(zhì)量，通過電氣檢測儀檢查線路是否存在短路或斷路情況。在這個過程中，技術(shù)人員憑借豐富的經(jīng)驗和專業(yè)知識，對故障進(jìn)行初步定位和分析。?

When the laparoscope malfunctions and is sent to the repair center, professional technicians will first communicate in detail with the department using it to understand the specific situation of the malfunction, such as whether the screen suddenly goes black during the surgery, whether the image is blurry, and whether there is fog on the lens. Subsequently, professional testing equipment was used to conduct a comprehensive examination of the laparoscope, including optical systems, electrical systems, mechanical structures, etc. For example, using a dedicated image testing card to check the imaging quality of the lens, and using an electrical detector to check for short circuits or open circuits in the circuit. During this process, technicians rely on their rich experience and professional knowledge to preliminarily locate and analyze faults. ?

二、拆解與清潔?

2、 Disassembly and Cleaning

確定故障部位后，技術(shù)人員會小心翼翼地對腹腔鏡進(jìn)行拆解。由于腹腔鏡結(jié)構(gòu)精密，內(nèi)部零件微小且脆弱，每一個操作都需高度謹(jǐn)慎，稍有不慎就可能損壞零件。拆解完成后，對各個零部件進(jìn)行深度清潔。對于光學(xué)鏡頭，使用專用的清潔劑和無塵擦拭布輕輕擦拭，去除表面的污漬、指紋和殘留的手術(shù)污染物；對于機(jī)械部件，采用超聲波清洗機(jī)進(jìn)行清洗，利用超聲波的空化效應(yīng)，清除部件縫隙中的污垢和雜質(zhì)，確保清潔徹底。?

After identifying the fault location, technicians will carefully disassemble the laparoscope. Due to the precise structure of laparoscopy and the small and fragile internal components, every operation requires a high degree of caution, as even a slight mistake may damage the parts. After disassembly, thoroughly clean each component. For optical lenses, use specialized cleaning agents and dust-free wiping cloths to gently remove surface stains, fingerprints, and residual surgical contaminants; For mechanical components, ultrasonic cleaning machines are used for cleaning, utilizing the cavitation effect of ultrasonic waves to remove dirt and impurities from the gaps of the components, ensuring thorough cleaning. ?

三、零件修復(fù)與更換?

3、 Parts repair and replacement

根據(jù)故障診斷結(jié)果，對損壞的零件進(jìn)行修復(fù)或更換。對于光學(xué)鏡頭的輕微劃痕，技術(shù)人員會采用專業(yè)的研磨和拋光技術(shù)進(jìn)行修復(fù)，恢復(fù)鏡頭的透光性和成像清晰度；若鏡頭出現(xiàn)嚴(yán)重破損或無法修復(fù)的情況，則更換為原廠同規(guī)格的鏡頭。對于電氣線路的故障，如線路老化、接觸不良等，會仔細(xì)排查并更換損壞的導(dǎo)線或接頭；對于機(jī)械結(jié)構(gòu)中的磨損部件，如密封環(huán)、彈簧等，及時進(jìn)行更換，確保機(jī)械部件的正常運(yùn)行和密封性。?

According to the fault diagnosis results, repair or replace the damaged parts. For minor scratches on optical lenses, technicians will use professional grinding and polishing techniques to repair them, restoring the transparency and imaging clarity of the lens; If the lens is severely damaged or irreparable, replace it with a lens of the same specifications from the original factory. For electrical circuit faults such as aging and poor contact, we will carefully investigate and replace damaged wires or connectors; For worn parts in mechanical structures, such as sealing rings, springs, etc., they should be replaced in a timely manner to ensure the normal operation and sealing of the mechanical components. ?

四、組裝與調(diào)試?

4、 Assembly and Debugging

在完成零件修復(fù)或更換后，按照嚴(yán)格的組裝順序?qū)⒏鱾€零部件重新組裝起來。組裝過程中，精確控制零件的安裝位置和緊固力度，確保各部件之間的配合精度。組裝完成后，對腹腔鏡進(jìn)行全面調(diào)試。再次檢測光學(xué)系統(tǒng)的成像質(zhì)量，調(diào)整焦距、白平衡等參數(shù)，使圖像達(dá)到最佳狀態(tài)；測試電氣系統(tǒng)的穩(wěn)定性，檢查設(shè)備是否能正常啟動、運(yùn)行，各項功能是否正常；對機(jī)械結(jié)構(gòu)進(jìn)行性能測試，如檢查鏡頭的旋轉(zhuǎn)、伸縮是否靈活順暢，器械通道是否暢通無阻等。只有通過所有調(diào)試環(huán)節(jié)，確保腹腔鏡各項指標(biāo)符合標(biāo)準(zhǔn)后，才會進(jìn)入下一個環(huán)節(jié)。?

After completing the repair or replacement of the parts, reassemble each component according to a strict assembly sequence. During the assembly process, accurately control the installation position and fastening force of the parts to ensure the precision of the fit between each component. After assembly, conduct comprehensive debugging of the laparoscope. Recheck the imaging quality of the optical system, adjust parameters such as focal length and white balance to achieve optimal image quality; Test the stability of the electrical system, check whether the equipment can start and operate normally, and whether all functions are normal; Conduct performance tests on mechanical structures, such as checking whether the rotation and extension of the lens are flexible and smooth, and whether the instrument passage is unobstructed. Only after ensuring that all indicators of the laparoscope meet the standards through all debugging steps, can we proceed to the next step. ?

五、質(zhì)量檢測與驗收?

5、 Quality inspection and acceptance

維修后的腹腔鏡還需經(jīng)過嚴(yán)格的質(zhì)量檢測。使用專業(yè)的檢測設(shè)備對其進(jìn)行全方位性能檢測，包括圖像分辨率、色彩還原度、亮度均勻性、電氣安全性等。同時，模擬手術(shù)環(huán)境進(jìn)行實(shí)際操作測試，檢驗腹腔鏡在真實(shí)使用場景下的穩(wěn)定性和可靠性。只有當(dāng)所有檢測項目都合格，并經(jīng)過使用科室的驗收確認(rèn)后，維修后的腹腔鏡才會被重新投入臨床使用。

The repaired laparoscope still needs to undergo strict quality inspection. Use professional testing equipment to conduct comprehensive performance testing, including image resolution, color reproduction, brightness uniformity, electrical safety, etc. At the same time, simulate the surgical environment for practical operation testing to verify the stability and reliability of laparoscopy in real use scenarios. Only when all testing items are qualified and confirmed by the using department, will the repaired laparoscope be put back into clinical use.
