Connector module for video endoscopic system

Abstract

An interface module for a video endoscopic system that permits the insertion tube to be connected to and disconnected from a video processor quickly and easily whereby sterilizing the tube is simplified and the substitution of one tube for another is greatly facilitated. The connector module interfaces the various video and other electric connections and also interfaces a fiber optic bundle connection and a fluid supply connection between the processor and insertion tube. A solid state imaging device is located at the distal end of the insertion tube, and this device is driven by signals received from the processor and transmits video signals back to the processor. The interface module contains circuitry that accepts standard input signals from the processor for driving the imaging device, and this circuitry includes means for adjusting the input signals so that they are compatible with the particular imaging device in the tube. The interface module also contains circuitry for transmitting video output signals from the imaging device to the video processor. This transmission circuitry includes a video amplifier and means for adjusting the gain of the amplifier so that its output drives the video processing circuitry as required for optimum video performance.
