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.

在這腹腔鏡攝像系統操作上，及時記錄和總結使用中、閱讀說明書和熟悉設備、配備必要的耗材和配件，簡單的事搞明白，復雜的事理清楚認真把事情做對、用心把事情做好。 用彩條信號可基本排除信號線及視器;攝像頭、適配器、導光束、光源、鏡子等連接是否正常?攝像頭連線接觸不對可造成無圖像;腹腔鏡攝像系統怎么樣好不好?視器、光源、電視系統的亮度、對比度設置不當可能使圖像無法看得清楚。

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.

圖像模糊，檢查攝像頭的焦距調節是否正常，免調焦功能是否打開;檢查及擦拭攝像頭的鏡面、適配器的鏡面;檢查及擦拭光學視管的兩個表面;檢查系統及視器的各個信號通道，尤其注意RGB通道;用彩條信號檢查視器設置是否正常?主要是對比度、亮度的設置;氣腹機的使用可造成光學視管鏡面起霧;使用可使圖像出現雪花樣干擾，從而影響圖像的清晰度。

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.

圖像太暗，檢查光源及其亮度設置，是否是用備用燈泡?是否使用高亮度設置?檢查調光電纜連接是否正常?檢查導光束與光學視管匹配是否正常?導光束是否有損壞(斷絲太多)?

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)?

檢查OTV的亮度設置是否太低?是否打開AGC?腹腔鏡攝像系統怎么樣好不好?檢查視器的亮度及對比度設置是否太低?檢查電源電壓是否太低?這對燈泡的亮度有影響，尤其是鹵素燈;檢查纖維鏡的導光束是否斷絲太多?高頻電刀使用中產生的煙霧可使圖像亮度受影響。

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.

圖像干擾：彩條信號區別類型：彩條有干擾多半屬于電源類，彩條正常屬于系統干擾;檢查外界電源有無干擾，如使用大功率設備，高頻、微波設備，包括高頻電刀、電焊機、核磁共振等;攝像頭斷線可能出現圖像異常或沒圖像。

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.
