在現(xiàn)代醫(yī)療技術(shù)的前沿領(lǐng)域，內(nèi)窺鏡設(shè)備已成為眾多科室不可或缺的診斷與治療工具。從耳鼻喉科的耳道、鼻腔檢查，到胃腸科的消化道內(nèi)窺，再到泌尿外科的膀胱鏡檢查等，內(nèi)窺鏡憑借其直觀、精準(zhǔn)的特性，為醫(yī)生提供了深入人體內(nèi)部的 “眼睛”，極大地提高了疾病診斷的準(zhǔn)確性和治療的有效性。然而，如同任何精密設(shè)備一樣，內(nèi)窺鏡設(shè)備在長期頻繁使用過程中，難免會出現(xiàn)各類故障，此時，專業(yè)的內(nèi)窺鏡設(shè)備維修便成為保障醫(yī)療工作順利開展的關(guān)鍵環(huán)節(jié)。

In the forefront of modern medical technology, endoscopic equipment has become an indispensable diagnostic and therapeutic tool for many departments. From ear, nose, and throat examinations in otolaryngology, to gastrointestinal endoscopy in gastroenterology, and to cystoscopy in urology, endoscopes provide doctors with an intuitive and precise "eye" that penetrates deep into the human body, greatly improving the accuracy of disease diagnosis and the effectiveness of treatment. However, like any precision equipment, endoscopic equipment is inevitably prone to various malfunctions during long-term and frequent use. At this time, professional maintenance of endoscopic equipment becomes a key link to ensure the smooth progress of medical work.

Key points of maintenance technology for endoscopic equipment

光學(xué)系統(tǒng)維修技術(shù)?

Optical system maintenance technology

鏡片清潔與更換：對于鏡頭鏡片上的灰塵、污漬，維修人員通常使用專業(yè)的清潔劑和無塵擦拭布進行清潔。清潔時要注意手法輕柔，避免劃傷鏡片表面。若鏡片出現(xiàn)破損或嚴(yán)重磨損，需要進行更換。更換鏡片時，要確保新鏡片的型號、規(guī)格與原鏡片一致，并且安裝位置準(zhǔn)確無誤。在安裝過程中，要使用專業(yè)的工具，如鏡片安裝夾具，保證鏡片的安裝精度，避免因安裝不當(dāng)導(dǎo)致圖像變形或模糊。?

Lens cleaning and replacement: For dust and stains on lens lenses, maintenance personnel usually use professional cleaning agents and dust-free wiping cloths for cleaning. When cleaning, pay attention to gentle techniques to avoid scratching the surface of the lens. If the lens is damaged or severely worn, it needs to be replaced. When replacing lenses, ensure that the model and specifications of the new lenses are consistent with the original lenses, and that the installation position is accurate. During the installation process, professional tools such as lens installation fixtures should be used to ensure the accuracy of lens installation and avoid image deformation or blurring caused by improper installation.

光學(xué)纖維束修復(fù)與更換：當(dāng)光學(xué)纖維束出現(xiàn)少量纖維折斷時，可以采用熔接技術(shù)進行修復(fù)。熔接過程需要使用專業(yè)的光纖熔接機，將折斷的纖維兩端進行精確對準(zhǔn)和熔接。對于纖維束損壞較為嚴(yán)重的情況，則需要進行整體更換。更換光學(xué)纖維束是一項技術(shù)要求極高的工作，需要在顯微鏡下進行操作，確保新纖維束的每一根纖維都能準(zhǔn)確連接到相應(yīng)的接口，并且在插入管內(nèi)的排布合理，避免出現(xiàn)彎折、扭曲等情況，以保證光線傳輸?shù)姆€(wěn)定性和圖像的清晰度。?

Repair and replacement of optical fiber bundles: When a small amount of fiber breakage occurs in the optical fiber bundle, fusion welding technology can be used for repair. The fusion process requires the use of a professional fiber fusion splicer to accurately align and fuse the two ends of the broken fiber. For cases where the fiber bundle is severely damaged, a complete replacement is required. Replacing optical fiber bundles is a highly technical task that requires operation under a microscope to ensure that each fiber of the new bundle can be accurately connected to the corresponding interface, and arranged reasonably inside the insertion tube to avoid bending, twisting, and other situations, in order to ensure the stability of light transmission and the clarity of the image. ?

插入管修復(fù)與更換：對于插入管外表面的輕微磨損或破損，可以使用專用的修補材料進行修復(fù)。修復(fù)時，要先對破損部位進行清潔和打磨，然后涂抹修補材料，按照規(guī)定的工藝進行固化處理。若插入管損壞嚴(yán)重，如鋼絲編織層斷裂、橡膠層大面積破損等，則需要更換整個插入管。更換插入管需要將內(nèi)窺鏡的操作部、目鏡等部件進行拆解，然后將新的插入管準(zhǔn)確安裝到位，并進行調(diào)試，確保插入管的柔韌性、彎曲角度等性能符合要求。?

Insertion tube repair and replacement: For minor wear or damage on the outer surface of the insertion tube, specialized repair materials can be used for repair. When repairing, the damaged area should be cleaned and polished first, and then repair materials should be applied and cured according to the prescribed process. If the insertion tube is severely damaged, such as the breakage of the steel wire weaving layer, extensive damage to the rubber layer, etc., the entire insertion tube needs to be replaced. Replacing the insertion tube requires disassembling the operating part, eyepiece, and other components of the endoscope, accurately installing the new insertion tube in place, and debugging to ensure that the flexibility, bending angle, and other performance of the insertion tube meet the requirements. ?

活檢鉗道疏通與修復(fù)：對于活檢鉗道堵塞的情況，維修人員首先使用專用的清洗工具，如高壓水槍、鉗道疏通刷等，對鉗道進行徹底清洗。若清洗后仍無法疏通，可能需要使用專業(yè)的鉗道修復(fù)工具，如擴張器、鉗道鏡等，對鉗道內(nèi)部進行檢查和修復(fù)。在修復(fù)過程中，要注意避免對鉗道造成二次損傷，同時確保修復(fù)后的鉗道密封性良好，能夠正常通過活檢鉗等器械。?

Biopsy forceps channel dredging and repair: For cases of biopsy forceps channel blockage, maintenance personnel first use specialized cleaning tools such as high-pressure water guns, forceps channel dredging brushes, etc. to thoroughly clean the forceps channel. If the blockage still cannot be cleared after cleaning, it may be necessary to use professional forceps repair tools such as dilators, forceps mirrors, etc. to inspect and repair the inside of the forceps. During the repair process, attention should be paid to avoiding secondary damage to the forceps channel, while ensuring that the repaired forceps channel has good sealing and can pass through biopsy forceps and other instruments normally. ?
