电子内镜的常见故障及预防（Common failure and prevention of electron endoscopy）

电子内镜的常见故障及预防（Common failure and prevention of electron endoscopy） Common failure and prevention of electron endoscopy Medical electronic endoscope is a kind of medical device which integrates high precision technology such as light, machine and electricity. In order to relieve the suffering of the patients, in the electronic lens inserted tube are doing fine as far as possible, in such a narrow space to accommodate all kinds of pipes, camera system, optical fiber bundle, Angle adjustment device, lifting clamp device and zoom system, etc., the degree of its sophisticated and delicate was palpable. Therefore, the correct operation and maintenance method is crucial. According to the problems encountered during the maintenance of electronic endoscopy in recent years, I believe that some failures can be avoided, and some common failures are discussed below. The mirror body loses its seal Electronic endoscope is the most important characteristics of built-in miniature with optoelectronic coupled devices (CCD) camera system, it is the heart part of the electronic endoscope, and endoscopic examination and treatment process is carried out in a liquid environment, therefore, the whole sealing of the lens body is particularly important. The part of the body that causes the lens to lose its seal is curved rubber and clamp tube. Bending rubber: one is inserted in the lens body of the front one can be freely bent part of about 10 cm long, it is made of very thin rubber wrapped, is the most temperamental part of the lens body, such as accidentally met its car or the edges of the desktop, or sharp objects and instruments, etc, will lead to bending rubber damage or holes and make the lens body lose tightness. Therefore, the operator should be careful and cautious in all aspects of the subject after leaving the receiver. 2. The clamp tube: in the process of endoscopic examination and treatment, clamp, tube is to check and treatment equipment of, if improper operation, easily lead to
