摘　　要：目的提高医用内窥镜临床使用的便捷性,解决带有传统目镜内窥镜的影像处理器及辅助系统体积过大、不便移动的问题。方法通过CCD的成像原理,将内窥镜目镜中的光学影像转成数字信号,数字信号通过无线或有线的传输方式,传送至TFT液晶屏,并还原出目镜中的影像。结果本文对整套系统从需求设计、软硬件开发、系统测试等各个环节做了详细的阐述,最终设计出图像分辨率为1920×1080,显示屏为5.6英寸,并带有拍照和摄像功能的便携式内窥镜显示系统,完全能够满足内窥镜成像的技术要求。结论该系统适合于紧急医疗事故、无外接电源、使用空间狭窄等受限环境,便于医生外出就诊,为病患提供上门服务,也可用于教学演示等。Objective To improve the convenience of medical endoscope in clinical use,and to solve the problem that the image processor and auxiliary system with traditional eyepiece endoscope are too large to move easily.Methods Based on the imaging principle of CCD,the optical image from an endoscope eyepiece was converted into the digital signal.Digital signals were transmitted to the TFT screen wirelessly or by wire,and restored the image in the eyepiece.Results We analyzed and explained the entire system from the aspects of demand design,software and hardware development,and system testing.Finally,a portable endoscope display system with photo and video functions was designed with image resolution of 1920×1080 and a display screen of 5.6 inches,which met the technical requirements of endoscopic imaging.Conclusion This system is suitable for restricted environments,such as emergency medical emergencies,limited power supply,and limited space.It was convenient for doctors to go out for treatment,provide on-site services for patients,and can be also used for teaching demonstrations.
