Abstract
Abstract A video camera for use in medical surgical procedure in conjunction with an endoscope is shown. The video camera includes an optical system for receiving and optically processing an optical image from an endoscope. A solid-state sensor-converter is operatively positioned to receive the optical image after it is passed through the optical system and for converts the optical image into an unprocessed video signal. A video processing circuit is located adjacent the optical system and is electronically connected to receive the output of the sensor convertor. The video processing circuit is mounted around the optical system and transmits preprocessed output signals as an output from the video electronic processing circuit to a remote location and to a video output circuit. A soakable enclosure surrounds the optical system, the solid-state sensor converter and the video electronic processing circuit and includes a sealing member for maintaining the same in operative relationship. An adapter permits the input of the optical image into the optical system and electrical conductors are used for transmission of the preprocessed output signals therefrom.
