在現(xiàn)代醫(yī)療體系中，內(nèi)窺鏡設(shè)備作為診斷與治療諸多疾病的 “神兵利器”，其重要性不言而喻。無(wú)論是胃鏡深入胃部探尋病變，還是腹腔鏡在腹腔內(nèi)輔助精準(zhǔn)手術(shù)，內(nèi)窺鏡都憑借獨(dú)特的可視化功能，為醫(yī)療工作者提供關(guān)鍵的診斷依據(jù)，極大提升了醫(yī)療服務(wù)的精準(zhǔn)性與有效性。然而，這類精密儀器在高頻使用過(guò)程中，極易出現(xiàn)各類故障，此時(shí)，專業(yè)的內(nèi)窺鏡設(shè)備維修便成為保障醫(yī)療流程順暢、維系患者健康的重要環(huán)節(jié)。

In the modern medical system, the importance of endoscopic equipment as a "divine weapon" for diagnosing and treating many diseases is self-evident. Whether it is gastroscopy exploring lesions in the stomach or laparoscopy assisting precise surgery in the abdominal cavity, endoscopes provide key diagnostic basis for medical workers with their unique visualization function, greatly improving the accuracy and effectiveness of medical services. However, such precision instruments are prone to various malfunctions during high-frequency use, and professional maintenance of endoscopic equipment becomes an important link in ensuring smooth medical processes and maintaining patient health.

故障檢測(cè)與診斷?

Fault detection and diagnosis

維修人員接到故障內(nèi)窺鏡后，首先會(huì)進(jìn)行全面的外觀檢查，查看是否有明顯的物理?yè)p傷，如外殼破裂、線纜破損等。接著，使用專業(yè)的檢測(cè)設(shè)備對(duì)內(nèi)窺鏡的光學(xué)、電子、機(jī)械系統(tǒng)進(jìn)行詳細(xì)測(cè)試。對(duì)于光學(xué)系統(tǒng)，通過(guò)光學(xué)檢測(cè)儀器評(píng)估圖像質(zhì)量、物鏡焦距、導(dǎo)光束亮度等參數(shù)；針對(duì)電子系統(tǒng)，利用示波器、信號(hào)發(fā)生器等設(shè)備檢測(cè)信號(hào)傳輸情況，判斷電子元件是否正常工作；在機(jī)械結(jié)構(gòu)方面，通過(guò)手動(dòng)操作彎曲部、活檢鉗道等，檢查其運(yùn)動(dòng)是否順暢，有無(wú)卡頓、異常阻力等現(xiàn)象。結(jié)合檢測(cè)數(shù)據(jù)與實(shí)際觀察，準(zhǔn)確判斷故障類型與具體位置。?

After receiving the faulty endoscope, the maintenance personnel will first conduct a comprehensive visual inspection to check for any obvious physical damage, such as shell rupture, cable damage, etc. Next, use professional testing equipment to conduct detailed tests on the optical, electronic, and mechanical systems of the endoscope. For optical systems, parameters such as image quality, objective lens focal length, and guide beam brightness are evaluated using optical detection instruments; For electronic systems, use equipment such as oscilloscopes and signal generators to detect signal transmission and determine whether electronic components are working properly; In terms of mechanical structure, manually operate the bending part, biopsy forceps, etc. to check whether their movement is smooth, whether there are any jamming, abnormal resistance, and other phenomena. By combining detection data with actual observation, accurately determine the type and specific location of the fault. ?

維修與更換零部件?

Repair and replacement of parts

根據(jù)故障診斷結(jié)果，維修人員采取相應(yīng)的維修措施。對(duì)于光學(xué)系統(tǒng)故障，若物鏡磨損較輕，可通過(guò)專業(yè)的研磨、拋光工藝進(jìn)行修復(fù)；鏡片污染則需使用專用的清潔劑進(jìn)行精細(xì)清洗；若導(dǎo)光束斷裂，需精確更換受損的導(dǎo)光纖維。電子系統(tǒng)故障維修時(shí)，對(duì)于損壞的圖像傳感器、集成電路等元件，需在防靜電環(huán)境下進(jìn)行精準(zhǔn)焊接更換；修復(fù)信號(hào)傳輸線路時(shí)，要仔細(xì)排查斷路、短路點(diǎn)，進(jìn)行焊接或線纜更換。機(jī)械結(jié)構(gòu)故障處理中，彎曲部鋼絲斷裂需更換全新鋼絲，并重新調(diào)試彎曲角度；角度控制裝置的磨損部件要進(jìn)行更換或修復(fù)，確保角度控制的準(zhǔn)確性；活檢鉗道堵塞則采用專用的疏通工具和清洗液進(jìn)行清理。?

According to the fault diagnosis results, maintenance personnel take corresponding maintenance measures. For optical system failures, if the objective lens wears lightly, it can be repaired through professional grinding and polishing processes; Lens contamination requires the use of specialized cleaning agents for fine cleaning; If the light guide beam breaks, the damaged light guide fiber needs to be replaced accurately. When repairing electronic system malfunctions, damaged components such as image sensors and integrated circuits need to be precisely welded and replaced in an anti-static environment; When repairing signal transmission lines, it is necessary to carefully investigate open circuits and short-circuit points, and perform welding or cable replacement. In the handling of mechanical structural faults, if the steel wire in the bending part breaks, it needs to be replaced with a new steel wire and the bending angle needs to be readjusted; The worn parts of the angle control device need to be replaced or repaired to ensure the accuracy of angle control; If the biopsy forceps are blocked, specialized dredging tools and cleaning solution are used for cleaning. ?

校準(zhǔn)與測(cè)試?

Calibration and Testing

維修完成后，為確保內(nèi)窺鏡設(shè)備恢復(fù)到最佳性能狀態(tài)，需進(jìn)行嚴(yán)格的校準(zhǔn)與測(cè)試。光學(xué)系統(tǒng)校準(zhǔn)包括圖像清晰度、色彩還原度、亮度均勻性等參數(shù)的調(diào)整；電子系統(tǒng)校準(zhǔn)要對(duì)圖像信號(hào)的增益、偏置等進(jìn)行優(yōu)化，保證圖像質(zhì)量穩(wěn)定；機(jī)械結(jié)構(gòu)校準(zhǔn)則著重調(diào)整彎曲部的彎曲角度范圍、活檢鉗道的開(kāi)合力度等。在校準(zhǔn)完成后，還需進(jìn)行模擬臨床使用的全面測(cè)試，包括將內(nèi)窺鏡插入模擬人體模型，檢查圖像質(zhì)量、角度控制、活檢鉗道功能等是否正常，只有通過(guò)測(cè)試的設(shè)備才能重新投入臨床使用。

After the repair is completed, strict calibration and testing are required to ensure that the endoscope equipment is restored to its optimal performance state. Optical system calibration includes adjusting parameters such as image clarity, color reproduction, and brightness uniformity; Electronic system calibration should optimize the gain and bias of image signals to ensure stable image quality; The mechanical structure calibration criteria focus on adjusting the bending angle range of the bending part and the opening and closing force of the biopsy forceps channel. After calibration is completed, comprehensive testing is required to simulate clinical use, including inserting an endoscope into a simulated human body model to check image quality, angle control, biopsy forceps function, etc. Only devices that pass the testing can be put back into clinical use.
