在医院的设备科，内窥镜维修师是“器械医生”——他们手中的内窥镜，既能深入人体探查病灶，也可能因一次意外跌落就“罢工”。从筷子粗细的胃镜到蛇形关节的胸腔镜，每一种内窥镜的“病况”都藏着独特的维修密码。

　　In the equipment department of the hospital, endoscope maintenance technicians are "instrument doctors" - the endoscopes in their hands can not only penetrate deep into the human body to explore lesions, but may also "strike" due to an accidental fall. From chopstick sized gastroscopes to snake shaped thoracoscopes, each type of endoscope has a unique repair code hidden in its "condition".

　　一、光学系统“视网膜修复”

　　1、 Optical system for retinal repair

　　镜头除雾术：

　　Lens defogging technique:

　　先用显微镜观察物镜组，若发现水渍状阴影，需拆解镜头组，用异丙醇+乙醚混合液浸泡清洗。

　　First, observe the objective lens group under a microscope. If water stains or shadows are found, disassemble the lens group and soak it in a mixture of isopropanol and ether for cleaning.

　　高端内窥镜配备“自加热除雾”功能，维修时需用示波器检测加热丝电阻，误差＞5%即需更换。

　　High end endoscopes are equipped with a "self heating defogging" function. During maintenance, an oscilloscope is needed to detect the resistance of the heating wire. If the error is greater than 5%, it needs to be replaced.

　　光纤断裂重生：

　　Fiber optic fracture regeneration:

　　传像束断裂是常见“绝症”，需用光纤切割刀制备新端面，再通过光学胶粘接，损耗率需控制在10%以内。

　　The breakage of the transmission beam is a common "terminal disease", which requires a fiber optic cutting knife to prepare a new end face, and then bonding it with optical adhesive. The loss rate needs to be controlled within 10%.

　　案例：某根传像束断裂50%，维修后分辨率从1080P降至720P，直接报废。

　　Case: A certain image transmission bundle broke by 50%, and after repair, the resolution decreased from 1080P to 720P, and it was directly scrapped.

　　CCD/CMOS“换眼手术”：

　　CCD/CMOS "Eye Replacement Surgery":

　　拆解内窥镜先端部，用热风枪加热传感器排线，力度过大易撕裂柔性电路板。

　　Disassemble the tip of the endoscope and heat the sensor cable with a hot air gun. Excessive force can easily tear the flexible circuit board.

　　新传感器需用标准色卡校准，色温偏差＞200K会导致图像偏色。

　　The new sensor needs to be calibrated with a standard color card, and a color temperature deviation greater than 200K will cause image color deviation.

　　二、机械结构“关节复位”

　　2、 Mechanical structure "joint reduction"

　　弯曲蛇骨“正骨”：

　　Curved snake bone "orthopedics":

　　胸腔镜蛇形关节卡顿？需用内窥镜专用润滑脂，粘度需控制在100-150cst之间。

　　Is the snake joint stuck during thoracoscopy? Special lubricating grease for endoscopes is required, with viscosity controlled between 100-150cst.

　　钢丝绳断裂是“高发伤”，更换时需保持预紧力，否则弯曲角度会偏差15°以上。

　　Wire rope breakage is a "high incidence of injury", and it is necessary to maintain pre tension when replacing it, otherwise the bending angle will deviate by more than 15 °.

　　插入管“植皮术”：

　　Inserting a tube for skin grafting:

　　外皮破损易引发“交叉感染”，需用医用级聚氨酯热缩管修补，耐酒精擦拭次数需＞500次。

　　Damaged outer skin can easily cause "cross infection" and requires repair with medical grade polyurethane heat shrink tubing. Alcohol resistant wiping should be done more than 500 times.

　　案例：某根插入管修补后，耐弯曲次数从2万次骤降至5千次，最终整体更换。

　　Case: After repairing a certain insertion tube, its bending resistance dropped sharply from 20000 times to 5000 times, and it was eventually replaced as a whole.

　　先端部“微整形”：

　　Micro shaping of the tip:

　　先端部撞击变形？需用精密夹具固定，再用0.1mm精度砂轮打磨，误差＞0.05mm会戳伤组织。

　　Deformation caused by impact at the tip? It needs to be fixed with precision fixtures, and then polished with a 0.1mm precision grinding wheel. An error greater than 0.05mm will puncture the tissue.

　　三、电子系统“心脏搭桥”

　　3、 Electronic system 'heart bridge'

　　线缆“通脉”：

　　Cable "pulse":

　　用时域反射仪（TDR）检测信号线断点，误差定位±1cm，开刀位置不对可能“误伤”其他线路。

　　Use a time domain reflectometer (TDR) to detect signal line breakpoints, with an error positioning of ± 1cm. Incorrect cutting position may "accidentally damage" other lines.

　　高频信号线需用同轴电缆替换，特性阻抗需严格匹配50Ω，否则图像会出现“重影”。

　　The high-frequency signal line needs to be replaced with coaxial cable, and the characteristic impedance needs to be strictly matched with 50 Ω, otherwise the image will show "ghosting".

　　主板“换芯”：

　　Motherboard "chip replacement":

　　用热风枪拆解BGA芯片，温度需精准控制在260±5℃，过高会“烫伤”焊盘。

　　Disassemble BGA chips with a hot air gun, and the temperature should be precisely controlled at 260 ± 5 ℃. If it is too high, it will "burn" the solder pads.

　　新芯片需刷写对应固件，版本不匹配会导致设备“变砖”。

　　The new chip needs to flash the corresponding firmware, and version mismatch can cause the device to 'brick'.

　　光源“续命”：

　　Light source "life extension":

　　氙灯老化？需用光谱仪检测色温，低于6000K必须更换，否则会影响医生判断组织颜色。

　　Xenon lamp aging? It is necessary to use a spectrometer to detect color temperature. If it is below 6000K, it must be replaced, otherwise it will affect the doctor's judgment of tissue color.

　　LED光源维修更简单，但需注意驱动电流，超过额定值10%寿命减半。

　　LED light source maintenance is simpler, but attention should be paid to the driving current. If it exceeds the rated value by 10%, the lifespan will be halved.

　　四、特殊维修“黑科技”

　　4、 Special maintenance "black technology"

　　气密性“体检”：

　　Airtightness "physical examination":

　　用氦质谱检漏仪检测内窥镜气密性，漏率＞1×10^-6Pa·m?/s即判定“溺水”。

　　Using a helium mass spectrometer leak detector to detect the airtightness of an endoscope, with a leakage rate greater than 1 × 10 ^ -6Pa · m? /S is judged as' drowning '.

　　维修后需做“水压试验”，0.2MPa压力下保持30分钟不渗水才算合格。

　　After maintenance, a "water pressure test" is required, and it is considered qualified if there is no water leakage for 30 minutes under a pressure of 0.2MPa.

　　超声清洗“排毒”：

　　Ultrasonic cleaning for detoxification:

　　生物污染内窥镜需用酶洗液+超声清洗，频率40kHz最佳，既能去污又不伤光学元件。

　　Biological contaminated endoscopes need to be cleaned with enzyme wash solution and ultrasound, with a frequency of 40kHz being optimal, which can remove dirt without damaging optical components.

　　案例：某根内窥镜因未彻底清洗，导致后续患者交叉感染，维修厂赔付上百万。

　　Case: A certain endoscope was not thoroughly cleaned, resulting in cross infection among subsequent patients, and the repair shop compensated millions.

　　老化测试“炼狱”：

　　Aging test 'purgatory':

　　维修后需模拟临床使用，连续弯曲5000次、高温高湿（40℃/90%RH）环境下运行24小时。

　　After maintenance, it is necessary to simulate clinical use by continuously bending 5000 times and running for 24 hours in a high temperature and high humidity (40 ℃/90% RH) environment.

　　高端设备还需做“跌落测试”，1米高度自由落体到硬质地面，功能正常才算过关。

　　High end devices also need to undergo a 'drop test', where they can freely fall from a height of 1 meter to a hard ground and function normally before passing the test.

　　五、维修避坑“红宝书”

　　5、 Repair and avoid pitfalls with the 'Red Treasure Book'

　　“小病大修”陷阱：

　　The trap of 'minor illness overhaul':

　　镜头起雾？先尝试除雾程序，80%的“病情”能缓解，直接换镜头组成本翻5倍。

　　Is the camera fogging up? First, try the defogging program. 80% of the "illness" can be relieved, and simply change the lens to make up this 5x zoom.

　　“李鬼”配件识别：

　　Identification of "Li Gui" accessories:

　　传像束看切割角度，原厂件呈45°斜面，副厂件多为90°直角，影响成像清晰度。

　　According to the cutting angle of the transmission beam, the original parts are inclined at a 45 ° angle, while the secondary parts are mostly at a 90 ° right angle, which affects the clarity of the imaging.

　　维修记录“溯源”：

　　Traceability of maintenance records:

　　要求维修厂提供“病历本”，记录故障代码、更换配件编号，便于后续追溯。

　　Request the repair shop to provide a "medical record book" to record fault codes and replacement part numbers for easy traceability in the future.

　　在内窥镜维修师眼中，没有“报废”的设备，只有未被开发的潜能。记住：每一次精准的维修，都是对生命的敬畏。下次再看到“手术成功”四个字时，不妨想想那些在幕后“救死扶伤”的维修师——他们手中的螺丝刀，同样在守护着生命的尊严。

　　In the eyes of an endoscope repairman, there are no "scrapped" devices, only untapped potential. Remember: every precise repair is a reverence for life. The next time you see the four words' successful surgery ', you may want to think of the repairman behind the scenes who' saves lives and helps the injured '- the screwdriver in their hand, also guarding the dignity of life.
