医用光学纤维内窥镜漏水故障分析（Analysis of leakage failure of medical optical fiber endoscope） Analysis of leakage failure of medical optical fiber endoscope Medical optical fiber endoscope has been in the hospital examination, treatment, operation, widely used in scientific research, the leakage phenomenon is one of the most common fault in medical fiberscope fault, light effect observation, serious when makes the fiber endoscope scrap. Check whether the machine is leaking, the operator must first understand the structure and function of fiber endoscope (orin buss and engage in Japan series fiber endoscope, for example), fiber endoscope consists of the eyepiece, light joints, and insert the operation. The eyepiece Used for observation of images and connection cameras and photographic equipment. Light guide joint For guiding light, water, steam supply and connecting cold light source, attractor and ancillary equipment. Operation department Used to adjust the direction of the desired image, the position of the treatment and the adjustment of water, gas, and the amount of attraction. Insert the Used to insert organs in the body. Its structure is complex, mainly include objective lens, guiding beam, guide beam, apex, bend pipe, snake tube, bend rubber, water pipe and attract pipeline. The basic structure of optical fiber endoscope as mentioned above, but as a result of their applications were different and produce all kinds of different types of endoscopy, including upper gastrointestinal fiberscope (upper), colonoscopy, enteroscopy, duodenum mirror, bronchoscopy and choledochoscope. In order to facilitate treatment, there are different types and structural parts. The following introduces the phenomenon of the leakage of optical fiber endoscope and the causes of these phenomena Image blur Once the endoscope leaks, the initial image is not clear. But not sure the image blur is caused by leaking, it is possible that apex protection glass is not clean or wear away, or oily mist is objec
