An electro-optical device (e.g., a CCD) designed to be attached, either directly or with an adaptor, to a flexible or rigid endoscope to allow real-time viewing of the internal anatomy during an endoscopic surgical procedure and to obtain moving-picture documentation of endoscopic findings and procedures. The device is designed for transducing visual images as a sequence of electronic data following a pre-established standard; the images are usually displayed sequentially on the screen of a monitor as a video image. The device may include audio recording capabilities.
