Title
(EN) DEVICE FOR HOLDING AN OPTICAL FIBER WITH PROLONGED LIFE TIME INCLUDING A HOLDING PIECE MADE AT LEAST PARTLY OF SAPPHIRE AND APPARATUS FOR GENERATING SHOCK WAVES EQUIPPED WITH SUCH A HOLDING DEVICE
(FR) DISPOSITIF DE MAINTIEN D'UNE FIBRE OPTIQUE A DUREE DE VIE AMELIOREE COMPORTANT UNE PIECE DE MAINTIEN REALISEE AU MOINS EN PARTIE EN SAPHIR ET APPAREIL DE GENERATION D'ONDES DE CHOC EQUIPE D'UN TEL DISPOSITIF DE MAINTIEN
Abstract
(EN)
The device for holding optical fibers is comprised of a holding piece (12) including an element (16) made at least partly of an optically transparent material (16) having a hardness sufficient to resist to light pulses and an optical index preferably higher than that of glass. Such a material consists preferably in sapphire. Preferably, the holding piece (12) includes a hollow cylinder (18) wherein is mounted towards its front face a sapphire which has a substantially annular shape. The invention allows to extend the life duration of optical fibers when applied to a connector device in apparatuses for generating shock waves, for destroying targets such as tissues, lithiases or concretions.
(FR)
L'invention concerne un dispositif de maintien de fibres optiques. Ce dispositif de maintien comprend une pièce de maintien (12) comprenant un élément (16) réalisé au moins en partie en un matériau (16) optiquement transparent ayant une dureté suffisante pour résister aux impulsions lumineuses, et un indice optique de préférence plus élévé que le verre. Un tel matériau est constitué de préférence par un saphir. De préférence, la pièce de maintien (12) comprend un cylindre creux (18) dans lequel est enchâssé vers sa face avant un saphir qui est de forme sensiblement annulaire. L'invention permet d'améliorer la durée de vie des fibres optiques dans le cadre de l'application du dispositif connecteur dans des appareils de génération d'ondes de choc, pour la destruction de cibles telles que tissus, lithiases ou concrétions.
