Abstract

Endoscope. Selon l'invention, cet endoscope est caractérisé en ce qu'il comporte un faisceau rigide et coudé de fibres conductrices de lumiere et assurant la transmission de l'image, telles que des fibres de verre ou analogues, solidaires les unes des autres et ordonnées de façon que l'emplacement de l'extrémité d'une desdites fibres dans une des sections d'extrémité dudit faisceau soit identique à l'emplacement de l'autre extrémité de ladite fibre dans l'autre section d'extrémité du faisceau. Endoscope coudé, à vision par contact, utilisé en particulier comme néphroscope (pyéloscope) pour la recherche des calculs dans les calices du rein.
