Abstract

See full text

The present invention relates to a filter switching device for a fluorescence endoscopic television camera system, and more particularly, to a filter switching device for a fluorescence endoscopic television camera system, which selectively transmits light to a detector sensor of a television camera according to the white light condition or the fluorescence condition to diagnose patients using a fluorescence endoscope. The present invention provides a filter switching device for a fluorescence endoscopic television camera system, which is configured to conveniently switch filters according to the rotational movement of the camera head, by inducing a change of magnetic forces according to the rotation of the camera head by magnetic substances disposed therein while maintaining a sealed structure inside the camera head connecting between a fluorescence endoscope and a television camera and thus allowing the frame of the camera head mounted with two types of filter to move upward and downward.
