The apparatuses hitherto used have a focusing optics to allow free choice of the irradiation distance and are therefore very large. Their mean minimum diameter is 12 mm and their length The small guide tubes of the optical fiber have diameters of 3 to 4 mm and are made in various shapes depending on the location of the application. This results in the need to change the small guide tube for each intervention Regardless of the undesirable interruption of the application, these changes imply an extension of the duration of the operation and a special reserve of small tubes of different curvatures which must be prepared for

Ce résultat est atteint selon l'invention par le fait que l'embout tubulaire allongé est fabriqué en un alliage  This result is achieved according to the invention in that the elongate tubular tip is made of an alloy

Le petit tube flexible 18 peut être fabriqué en un alliage de laiton mou, mais on peut aussi envisager d'autres alliages L'essentiel est que le petit tube puisse être facilement courbé à la main sans qu'il se produise d'amorce de rupture et qu'il puisse être à chaque instant ramené à sa position première D'autres alliages métalliques en plomb ou en zinc peuvent bien entendu être aussi envisagés, la condition  The small flexible tube 18 can be made of a soft brass alloy, but other alloys can also be envisaged. The essential point is that the small tube can be easily bent by hand without breaking primer. and that it can be brought back to its original position at any moment. Other metal alloys made of lead or zinc can of course also be envisaged.
