The video endoscope represents a new generation of endoscopic instruments. The main feature is an intragastric CCD-chip transforming the optical impulses into electronic signals. The latter are transmitted without any optical fibre bundle, transformed by a video processor and visualized on a television screen. The present experience show drawbacks in respect to mechanical properties of the endoscopes, to reproduction of colors (esp. red) and photographic documentation. On the other hand the excellent image quality guarantees convenient handling for investigator, information for attending persons (doctors, nurses, students), improved conditions for documentation and control of quality. Although the video-endoscope is not replacing fibre endoscopes at present, further improvement will promote its general acceptance.
视频内窥镜代表了新一代的内窥镜器械。其主要特点是胃内的CCD芯片将光脉冲转化为电信号。这些电信号无需任何光纤束进行传输，而是由视频处理器进行转换，并在电视屏幕上显示出来。目前的经验表明，在内窥镜的机械性能、颜色再现（尤其是红色）和摄影记录方面存在缺陷。另一方面，出色的图像质量保证了研究人员操作方便，为在场人员（医生、护士、学生）提供信息，改善了记录条件和质量控制。虽然目前视频内窥镜还不能取代纤维内窥镜，但进一步改进将促进其被广泛接受。
