在現(xiàn)代醫(yī)療領(lǐng)域，內(nèi)窺鏡設(shè)備宛如醫(yī)生的 “第三只眼”，憑借其能夠深入人體內(nèi)部、清晰呈現(xiàn)器官組織狀況的卓越能力，成為疾病診斷與治療過程中不可或缺的關(guān)鍵工具。無論是消化道疾病的排查、呼吸道病癥的診斷，還是各類微創(chuàng)手術(shù)的實施，內(nèi)窺鏡設(shè)備都發(fā)揮著無可替代的作用。然而，如同任何精密儀器一樣，內(nèi)窺鏡設(shè)備在長期頻繁使用過程中，難免會出現(xiàn)各種故障，此時，專業(yè)、高效的維修服務(wù)便成為保障其持續(xù)精準(zhǔn)運行，維系醫(yī)療工作正常開展的關(guān)鍵防線。?

In the modern medical field, endoscopic equipment is like a doctor's "third eye". With its excellent ability to penetrate deep into the human body and clearly present the condition of organs and tissues, it has become an indispensable key tool in the process of disease diagnosis and treatment. Endoscopic equipment plays an irreplaceable role in the screening of digestive diseases, diagnosis of respiratory diseases, and implementation of various minimally invasive surgeries. However, like any precision instrument, endoscopic equipment is inevitably prone to various malfunctions during long-term and frequent use. At this time, professional and efficient maintenance services become the key defense line to ensure its continuous and accurate operation and maintain the normal development of medical work. ?

內(nèi)窺鏡設(shè)備的重要地位與故障頻發(fā)挑戰(zhàn)?

The Importance of Endoscopic Equipment and the Challenges of Frequent Malfunctions

內(nèi)窺鏡設(shè)備以其直觀、準(zhǔn)確的檢查優(yōu)勢，極大地提高了疾病診斷的準(zhǔn)確性和效率。在消化內(nèi)科，胃腸鏡能夠直接觀察食管、胃、腸道等部位的黏膜病變，幫助醫(yī)生及時發(fā)現(xiàn)胃潰瘍、息肉、腫瘤等疾病，為后續(xù)治療提供重要依據(jù)。在呼吸內(nèi)科，支氣管鏡可深入氣管和支氣管，對肺部疾病進行精準(zhǔn)診斷，在肺癌早期篩查中發(fā)揮著關(guān)鍵作用。在外科手術(shù)領(lǐng)域，腹腔鏡、關(guān)節(jié)鏡等內(nèi)窺鏡設(shè)備使微創(chuàng)手術(shù)得以廣泛開展，降低了手術(shù)創(chuàng)傷，縮短了患者康復(fù)時間。?

Endoscopic equipment, with its intuitive and accurate inspection advantages, greatly improves the accuracy and efficiency of disease diagnosis. In gastroenterology, gastroscopy can directly observe mucosal lesions in the esophagus, stomach, intestines, and other areas, helping doctors detect gastric ulcers, polyps, tumors, and other diseases in a timely manner, providing important evidence for subsequent treatment. In respiratory medicine, bronchoscopy can penetrate deep into the trachea and bronchi to accurately diagnose lung diseases, playing a key role in early screening of lung cancer. In the field of surgical procedures, endoscopic devices such as laparoscopy and arthroscopy enable minimally invasive surgery to be widely performed, reducing surgical trauma and shortening patient recovery time. ?

但內(nèi)窺鏡設(shè)備的精密性和使用環(huán)境的特殊性，使其面臨較高的故障風(fēng)險。一方面，設(shè)備需頻繁進入人體內(nèi)部，在復(fù)雜的生理環(huán)境中工作，容易受到胃酸、膽汁、血液等腐蝕性物質(zhì)的侵蝕，導(dǎo)致鏡體表面磨損、管道堵塞、電子元件損壞等問題。另一方面，在日常使用過程中，由于操作不當(dāng)，如過度彎曲鏡身、碰撞硬性物體等，也可能引發(fā)鏡體折斷、圖像模糊、光源異常等故障。據(jù)不完全統(tǒng)計，約 70% 的內(nèi)窺鏡設(shè)備在使用 3 - 5 年后，會因各種原因出現(xiàn)不同程度的故障，嚴(yán)重影響醫(yī)療工作的正常進行。

However, the precision of endoscopic equipment and the particularity of its usage environment pose a high risk of malfunction. On the one hand, the equipment needs to frequently enter the human body and work in a complex physiological environment, which is easily corroded by corrosive substances such as stomach acid, bile, and blood, leading to problems such as surface wear of the mirror, pipeline blockage, and damage to electronic components. On the other hand, in daily use, improper operation such as excessive bending of the mirror body, collision with hard objects, etc. may also cause faults such as mirror breakage, blurred images, and abnormal light sources. According to incomplete statistics, about 70% of endoscopic equipment will experience varying degrees of malfunctions due to various reasons after 3-5 years of use, seriously affecting the normal operation of medical work.

常見故障類型與維修要點解析?

Analysis of Common Fault Types and Maintenance Points

光學(xué)系統(tǒng)故障?

Optical system malfunction

內(nèi)窺鏡的光學(xué)系統(tǒng)負責(zé)將人體內(nèi)部的圖像清晰地傳輸至醫(yī)生視野，一旦出現(xiàn)故障，將直接影響診斷和治療效果。常見的光學(xué)系統(tǒng)故障包括圖像模糊、有黑斑或條紋、亮度不足等。圖像模糊可能是由于物鏡表面沾染污漬、光學(xué)鏡片磨損或位移導(dǎo)致。維修時，需專業(yè)維修人員使用高精度的清潔工具和設(shè)備，對物鏡進行仔細清潔，若鏡片磨損或位移，則需借助精密儀器進行校準(zhǔn)和更換。對于亮度不足的問題，可能是光源燈泡老化、光纖斷裂或?qū)Ч庀到y(tǒng)故障。維修人員需排查光源系統(tǒng)各部件，更換老化燈泡，修復(fù)或更換斷裂的光纖，確保導(dǎo)光系統(tǒng)正常工作。?

The optical system of an endoscope is responsible for transmitting the internal images of the human body clearly to the doctor's field of view. Once a malfunction occurs, it will directly affect the diagnosis and treatment effectiveness. Common optical system failures include blurry images, black spots or stripes, insufficient brightness, etc. Image blur may be caused by stains on the surface of the objective lens, wear or displacement of the optical lens. When repairing, professional maintenance personnel need to use high-precision cleaning tools and equipment to carefully clean the objective lens. If the lens is worn or displaced, precision instruments need to be used for calibration and replacement. For the issue of insufficient brightness, it may be due to aging of the light source bulb, fiber breakage, or malfunction of the light guiding system. Maintenance personnel need to inspect all components of the light source system, replace aging bulbs, repair or replace broken optical fibers, and ensure the normal operation of the light guiding system. ?

電子系統(tǒng)故障?

Electronic system malfunction

隨著內(nèi)窺鏡技術(shù)的不斷發(fā)展，電子系統(tǒng)在設(shè)備中的作用愈發(fā)重要。電子系統(tǒng)故障可能導(dǎo)致圖像信號傳輸異常、設(shè)備死機、無法開機等問題。例如，攝像頭芯片損壞會使圖像出現(xiàn)噪點、色彩失真或無圖像輸出。維修此類故障，需要維修人員具備扎實的電子電路知識，能夠使用專業(yè)的電子檢測設(shè)備，如示波器、邏輯分析儀等，對電路板上的芯片、電容、電阻等元件進行檢測和更換。同時，對于軟件系統(tǒng)出現(xiàn)的故障，如設(shè)備驅(qū)動程序損壞、操作系統(tǒng)崩潰等，維修人員需熟練掌握設(shè)備的軟件安裝和調(diào)試方法，進行相應(yīng)的修復(fù)和升級。

With the continuous development of endoscopic technology, the role of electronic systems in devices has become increasingly important. Electronic system failures may cause issues such as abnormal image signal transmission, device crashes, and inability to power on. For example, damaged camera chips can cause noise, color distortion, or no image output in the image. To repair such faults, maintenance personnel need to have solid knowledge of electronic circuits and be able to use professional electronic testing equipment such as oscilloscopes, logic analyzers, etc. to detect and replace components such as chips, capacitors, resistors, etc. on the circuit board. At the same time, for software system failures such as device driver program damage, operating system crashes, etc., maintenance personnel need to be proficient in the software installation and debugging methods of the device, and carry out corresponding repairs and upgrades.
