How about the laparoscopic camera system of medical imaging equipment? On the premise of ensuring the image quality, the actual factors such as equipment maintainability, failure rate, overall cost and later cost are considered. Laparoscopic camera system is a common medical equipment system, and laparoscopic camera system needs to be understood in this application, system composition, common faults, countermeasures and so on. First of all, the application of endoscopy is all pervasive and hole making. Laparoscopy is the eye of endoscopy technology. In this camera system, the utilization rate of laparoscopic camera system is also high.

在这腹腔镜摄像系统操作上，及时记录和总结使用中、阅读说明书和熟悉设备、配备必要的耗材和配件，简单的事搞明白，复杂的事理清楚认真把事情做对、用心把事情做好。 用彩条信号可基本排除信号线及视器;摄像头、适配器、导光束、光源、镜子等连接是否正常?摄像头连线接触不对可造成无图像;腹腔镜摄像系统怎么样好不好?视器、光源、电视系统的亮度、对比度设置不当可能使图像无法看得清楚。

In the operation of this laparoscopic camera system, timely record and summarize the use, read the instructions and get familiar with the equipment, and equip with necessary consumables and accessories. Understand the simple things, clarify the complex things, and carefully do things right and do things well. The color bar signal can basically eliminate the signal line and camera; Is the connection of camera, adapter, guide beam, light source and mirror normal? Incorrect contact of camera wiring can cause no image; How about the laparoscopic camera system? Improper brightness and contrast settings of the camera, light source and TV system may make the image impossible to see clearly.

图像模糊，检查摄像头的焦距调节是否正常，免调焦功能是否打开;检查及擦拭摄像头的镜面、适配器的镜面;检查及擦拭光学视管的两个表面;检查系统及视器的各个信号通道，尤其注意RGB通道;用彩条信号检查视器设置是否正常?主要是对比度、亮度的设置;气腹机的使用可造成光学视管镜面起雾;使用可使图像出现雪花样干扰，从而影响图像的清晰度。

If the image is blurred, check whether the focal length adjustment of the camera is normal and whether the focus free function is turned on; Check and wipe the mirror of camera and adapter; Check and wipe the two surfaces of the optical tube; Check each signal channel of the system and the camera, especially the RGB channel; Check whether the camera setting is normal with the color bar signal? Mainly the setting of contrast and brightness; The use of pneumoperitoneum machine can cause fog on the mirror surface of optical tube; Use can make the image appear snowflake like interference, thus affecting the clarity of the image.

图像太暗，检查光源及其亮度设置，是否是用备用灯泡?是否使用高亮度设置?检查调光电缆连接是否正常?检查导光束与光学视管匹配是否正常?导光束是否有损坏(断丝太多)?

The image is too dark. Check the light source and its brightness setting. Is it a spare bulb? Use high brightness setting? Check whether the dimmer cable connection is normal? Check whether the guide beam matches the optical tube normally? Is the guide beam damaged (too many broken wires)?

检查OTV的亮度设置是否太低?是否打开AGC?腹腔镜摄像系统怎么样好不好?检查视器的亮度及对比度设置是否太低?检查电源电压是否太低?这对灯泡的亮度有影响，尤其是卤素灯;检查纤维镜的导光束是否断丝太多?高频电刀使用中产生的烟雾可使图像亮度受影响。

Check whether the brightness setting of OTV is too low? Turn on AGC? How about the laparoscopic camera system? Check whether the brightness and contrast settings of the camera are too low? Check whether the power supply voltage is too low? This has an impact on the brightness of the bulb, especially the halogen lamp; Check whether there are too many broken wires in the guide beam of the fiberscope? The smoke generated in the use of high-frequency electric knife can affect the brightness of the image.

图像干扰：彩条信号区别类型：彩条有干扰多半属于电源类，彩条正常属于系统干扰;检查外界电源有无干扰，如使用大功率设备，高频、微波设备，包括高频电刀、电焊机、核磁共振等;摄像头断线可能出现图像异常或没图像。

Image interference: color bar signal difference type: color bar interference mostly belongs to power supply, and color bar normal belongs to system interference; Check the external power supply for interference, such as using high-power equipment, high-frequency and microwave equipment, including high-frequency electric knife, electric welding machine, nuclear magnetic resonance, etc; If the camera is disconnected, there may be abnormal image or no image.
