Endoscope system
First Claim
1. An endoscope system including a line transfer type CCD solid-state camera located within the distal end of an endoscope, said camera providing a video output to a television monitor so that an affected area can be treated with laser radiation while being observed, said system comprising:
- a light source for providing illumination;
a laser oscillator for producing said laser radiation;
blocking means for blocking said illumination from said light source and said laser radiation from said laser oscillator from impinging upon said CCD camera at least during a period of operation when said CCD camera is in a transfer mode; and
locating means for locating and displaying at least a portion of a path followed by said laser radiation on said television monitor.

Abstract
An endoscope system includes a CCD camera of the line transfer type located at and within the distal end of an endoscope. The camera produces and supplies a video output to a television monitor, thus enabling medical treatment with laser radiation while the affected area is under observation. Illumination of the affected area and laser radiation used for the medical treatment, are blocked at selected intervals to prevent them from impinging upon the CCD camera at least during a period of operation when the camera is in a charge transfer mode.
