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.
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.
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.
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)?
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.
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.
