ABSTRACT:
A highly focusable video camera for use in medical and surgical procedures in conjunction with an endoscope is shown. The video camera includes a cylindrical body defining a confinement space having an open end and a cover having an aperture on a top portion and a cylindrical sleeve which extends into the cylindrical body portion. An optical system is mounted on the cover and extends into the cylindrical body and the optical system receives and passes an optical image from an endoscope. The optical system is focusable by relative movement along its optical axis. The internal surface of the cylindrical body has a groove which is formed to have an axial pitch and the groove functions as a cam surface to receive and coact with a follower which is connected to the cylindrical sleeve. A sealing means is located between the interior surface of the body and the external surface of the body and the external surface of the sleeve for blocking passage of the fluid into the containment space. A solid-state sensor-converter is operatively positioned to receive the optical image after it is passed through the optical system and converts the optical image into an unprocessed video signal. A video processing circuit receives the output of the sensor converter and transmits preprocessed output signals as an output to a remote location and to a video output circuit.
