近年来，虽然内窥镜的质量在稳步提高，但作为一种异常和娇贵的设备，每天的高压灭菌，消毒供应人员的不正当操作，手术器械的随意摆放导致的碰撞等，都可能会引|起光学部件的损坏，内窥镜设备维修人员认为损坏的情况大致有以下几个方面:

In recent years, although the quality of endoscopes has been steadily improved, as an unusual and delicate equipment, the daily high-pressure sterilization, improper operation of disinfection supply personnel, collision caused by random placement of surgical instruments, etc. may cause damage to optical components. Endoscopic equipment maintenance personnel think that the damage is generally in the following aspects:

视野大小改变

Visual field size change

内窥镜的视野大小是由其顶端处影像左边和右边的夹角所决定的，其控制视野监视器上显示的影像圆周的大小。一旦视野大小发生变化则应该显示的图像就会偏移或者显示不出来，将会严重影响临床医生的操作，出现这种情况一般的原因有:

The field of view size of the endoscope is determined by the angle between the left and right sides of the image at its top, which controls the size of the image circumference displayed on the field of view monitor. Once the field of vision changes, the image that should be displayed will shift or not be displayed, which will seriously affect the clinician's operation. The general reasons for this are:

①目镜损坏;

① The eyepiece is damaged;

②视频适配器故障;

② Video adapter failure;

③CCD制式的改变等。

③ Change of CCD system, etc.

影像传送失真或者有光晕现象

Distorted image transmission or halo

一般来说，影像在传送过程中，纤维光纤的照相应和透镜系统的光圈大小有很大的关系，一旦其传送过程之中某一环节出现问题，就会引起影像失真或是边缘模糊、暗淡，同时出现光晕现象。此时如果增加光源的亮度能看清视野的边缘，但中心部位会变得过于明亮刺眼，弓|起这种故障原因大部分是由于内镜中的透镜出现故障。

Generally speaking, in the process of image transmission, the photography of fiber optic fiber should have a great relationship with the aperture size of the lens system. Once a problem occurs in a certain link in the transmission process, it will cause image distortion or blurring, dimming, and halo. At this time, if the brightness of the light source is increased, the edge of the field of vision can be seen clearly, but the central part will become too bright and dazzling. The cause of this failure is mostly due to the failure of the lens in the endoscope.

图像模糊或过暗

The image is blurry or too dark

出现图像模糊或者图像过暗现象时，对于维修工程人员来说找出具体问题比较困难。一般出现此故障，主要有以吓几方面的原因:

When the image is blurry or too dark, it is difficult for maintenance engineers to find out the specific problems. This fault usually occurs for several reasons:

①光纤着色层与光纤老化，引起光源能量输出降低;

① The colored layer of optical fiber and the aging of optical fiber cause the reduction of the energy output of the light source;

②光传输到光纤时，光源内灯泡未对准光纤头或光源内其它光学部件未对准而导致光输出能量减少;

② When the light is transmitted to the optical fiber, the light bulb in the light source is not aligned with the optical fiber head or other optical components in the light source are not aligned, resulting in the reduction of light output energy;

③光纤内可能有断裂的纤维或纤维末端部有损坏;

③ There may be broken fibers in the optical fiber or the end of the fiber is damaged;

④内镜系统方面包括摄像头、摄像线、适配器、适配环、图像处理器以及显示器等某-部件的故障。

④ The endoscopic system includes the failure of camera, camera line, adapter, adapter ring, image processor, display and other components.

如果要区分具体故障部位，一般要采用代替法加以区分。通常情况如果整幅图像模糊，可能为内镜系统故障或光纤有未完全断裂现象;若边缘模糊表示内镜的尖端纤维没有足够弯曲或光纤末端有毛糙现象。更多相关内容就来我们网站http://www.jiangrenyiliao.cn咨询看看吧！

If you want to distinguish specific fault parts, you should generally use the substitution method to distinguish them. In general, if the whole image is blurred, it may be the endoscopic system failure or incomplete fracture of optical fiber; If the edge is vague, it means that the tip fiber of the endoscope is not bent enough or the end of the fiber is rough.
