Abstract

L'invention concerne un photo-endoscope comportant un tube-éclair électronique qui est engagé dans le tube optique métallique sur le côté distal d'examen, ce tube étant pourvu d'un fourreau protecteur transparent et étant disposé avec une masse d'enrobage transparent dans un boîtier métallique pourvu d'un évidement orienté dans la direction d'observation. Ce photo-endoscope comprend une tige métallique 16 entourant le système optique 1, le tube-éclair 4 et le conducteur optique 11 et pourvue d'évidements 18, 19 en forme de fenêtres pour permettre l'observation et l'orientation du rayon émis par le tube-éclair et dans l'extrémité distale de laquelle est fixé un fourreau cylindrique transparent 20 s'étendant à peu près sur la longueur du tube-éclair et présentant une épaisseur de paroi renforcée dans la zone de la sortie du rayonnement du tube-éclair. Photo-endoscope permettant d'éviter dans tous les cas la pénétration d'éclats ou de la masse d'enrobage dans la cavité du corps, par exemple en cas d'éclatement du tube-éclair.
