椎間孔鏡作為現(xiàn)代脊柱微創(chuàng)手術(shù)的核心器械，其精密結(jié)構(gòu)決定了維修工作的復(fù)雜性。當這臺集光學、機械、電子技術(shù)于一體的設(shè)備出現(xiàn)故障時，維修人員需建立系統(tǒng)化的配件更換方案。從臨床使用反饋與技術(shù)文檔分析，可將維修配件分為六大核心模塊。

　　As the core instrument of modern minimally invasive spinal surgery, the precision structure of intervertebral foramen endoscope determines the complexity of maintenance work. When this equipment that integrates optical, mechanical, and electronic technologies malfunctions, maintenance personnel need to establish a systematic replacement plan for parts. Based on clinical feedback and technical documentation analysis, maintenance parts can be divided into six core modules.

　　光學系統(tǒng)配件構(gòu)成視覺傳遞鏈路。物鏡組作為成像起點，其多組柱狀透鏡通過不銹鋼管固定，壁厚僅0.1毫米的管體在受到外力沖擊時易變形，導(dǎo)致透鏡移位。當出現(xiàn)圖像模糊或彩虹現(xiàn)象時，需整體更換物鏡系統(tǒng)。中繼鏡組中的棱鏡與窗口鏡片，在長期消毒過程中可能產(chǎn)生膜層脫落，需采用真空鍍膜工藝修復(fù)。目鏡端的色環(huán)與光錐，負責色彩還原與光束整形，其精密配合公差需控制在0.02毫米以內(nèi)。

　　Optical system components form the visual transmission chain. The objective lens group serves as the starting point for imaging, with multiple sets of cylindrical lenses fixed in stainless steel tubes. The tube body, with a wall thickness of only 0.1 millimeters, is prone to deformation when subjected to external impact, resulting in lens displacement. When image blurring or rainbow phenomenon occurs, the entire objective lens system needs to be replaced. The prisms and window lenses in the relay lens group may experience film peeling during long-term disinfection and require vacuum coating technology for repair. The color ring and cone at the eyepiece end are responsible for color reproduction and beam shaping, with a precision fit tolerance controlled within 0.02 millimeters.

　　照明通路配件保障手術(shù)視野清晰。光纖組件作為光能載體，采用石英材質(zhì)多模光纖，在頻繁彎折使用中易出現(xiàn)斷裂。當光源亮度衰減超過30%時，需檢測光纖耦合效率。冷光源模塊中的LED芯片，其色溫穩(wěn)定性直接影響手術(shù)視野真實性，當色溫漂移超過500K時必須更換。導(dǎo)光束接頭的陶瓷插芯，需確保與光源接口的同軸度，微小偏差都會導(dǎo)致光斑畸變。

　　Lighting pathway accessories ensure clear surgical field of view. Fiber optic components, as carriers of light energy, use quartz material multimode fibers, which are prone to breakage during frequent bending and use. When the brightness attenuation of the light source exceeds 30%, the fiber coupling efficiency needs to be tested. The color temperature stability of the LED chip in the cold light source module directly affects the authenticity of the surgical field of view, and must be replaced when the color temperature drift exceeds 500K. The ceramic plug of the light guide beam connector needs to ensure coaxiality with the light source interface, as even small deviations can cause distortion of the light spot.

　　機械傳動配件維持操作精度。工作管采用醫(yī)用不銹鋼經(jīng)深孔加工而成，內(nèi)壁粗糙度需達到Ra0.4以下。當前端出現(xiàn)擊傷或彎曲時，需采用電解拋光工藝修復(fù)。器械通道的硅膠密封件，在反復(fù)插拔手術(shù)器械后易產(chǎn)生永久變形，導(dǎo)致氣密性失效。操作手柄中的角度傳感器，其電阻值漂移超過5%將影響導(dǎo)航精度，需進行標定或更換。

　　Mechanical transmission components maintain operational accuracy. The work tube is made of medical grade stainless steel through deep hole machining, and the inner wall roughness needs to reach Ra0.4 or below. When there is damage or bending on the front end, electrolytic polishing technology should be used for repair. The silicone seal of the instrument channel is prone to permanent deformation after repeated insertion and removal of surgical instruments, resulting in air tightness failure. If the resistance value of the angle sensor in the joystick drifts by more than 5%, it will affect the navigation accuracy and needs to be calibrated or replaced.

　　密封防護配件構(gòu)建安全屏障。物鏡系統(tǒng)的環(huán)氧樹脂密封膠，在高溫消毒后易發(fā)生黃變，當硬度超過肖氏D80時需徹底清除重新灌封。O型密封圈采用氟橡膠材質(zhì)，在化學消毒劑浸泡后可能產(chǎn)生溶脹，需定期測量斷面直徑。防水透氣膜作為關(guān)鍵防護件，其孔隙率需控制在30-50納米之間，既要阻隔液體又要平衡內(nèi)外壓差。

　　Seal protective accessories to build a safety barrier. The epoxy resin sealant of the objective lens system is prone to yellowing after high-temperature disinfection. When the hardness exceeds Shore D80, it needs to be thoroughly removed and re sealed. The O-ring is made of fluororubber material, which may swell after soaking in chemical disinfectants, and the cross-sectional diameter needs to be measured regularly. As a key protective component, the porosity of waterproof breathable membrane needs to be controlled between 30-50 nanometers, which not only blocks liquids but also balances the internal and external pressure difference.

　　電子控制配件保障系統(tǒng)穩(wěn)定。圖像處理板上的CMOS傳感器，其暗電流超過0.5nA時將產(chǎn)生噪聲點。信號傳輸線的屏蔽層，在反復(fù)彎曲后可能斷裂，需用矢量網(wǎng)絡(luò)分析儀檢測特性阻抗。電源模塊中的濾波電容，其等效串聯(lián)電阻超過100毫歐時需更換，避免電壓波動影響設(shè)備運行。

　　Electronic control accessories ensure system stability. The CMOS sensor on the image processing board will generate noise points when its dark current exceeds 0.5nA. The shielding layer of the signal transmission line may break after repeated bending, and a vector network analyzer is needed to detect the characteristic impedance. When the equivalent series resistance of the filtering capacitor in the power module exceeds 100 milliohms, it needs to be replaced to avoid voltage fluctuations affecting equipment operation.

　　輔助功能配件完善系統(tǒng)集成。吸引器接頭的錐度密封面，在長期使用后可能磨損，需用氣密檢測儀驗證泄漏率。可旋轉(zhuǎn)固定架的阻尼軸承，其扭矩衰減超過30%時需更換，確保手術(shù)過程中的穩(wěn)定性。這些輔助配件雖不直接參與核心功能，但對整體性能有著重要影響。

　　Improve system integration with auxiliary functional accessories. The tapered sealing surface of the attractor joint may wear out after long-term use, and it is necessary to verify the leakage rate with an airtight detector. When the torque attenuation of the damping bearing of the rotatable fixed frame exceeds 30%, it needs to be replaced to ensure stability during the surgical process. These auxiliary accessories, although not directly involved in core functions, have a significant impact on overall performance.

　　椎間孔鏡維修需要建立標準化配件更換流程。通過故障樹分析法定位失效環(huán)節(jié)，結(jié)合設(shè)備日志追溯使用記錄，可制定出經(jīng)濟高效的維修方案。維修過程中需使用原廠級檢測設(shè)備，如光斑分析儀、三坐標測量機等，確保修復(fù)后的設(shè)備性能達到出廠標準。這種系統(tǒng)化的配件管理策略，既能延長設(shè)備使用壽命，又能保障臨床手術(shù)安全。

　　The maintenance of intervertebral foramen endoscope requires the establishment of a standardized accessory replacement process. By using the fault tree analysis method to locate the faulty link and combining it with equipment logs to trace usage records, an economical and efficient maintenance plan can be developed. During the maintenance process, original factory level testing equipment such as spot analyzers and coordinate measuring machines should be used to ensure that the performance of the repaired equipment meets the factory standards. This systematic accessory management strategy can not only extend the service life of equipment, but also ensure the safety of clinical surgery.
