Title
(EN) ENDOSCOPE WITH CURVED END IMAGE GUIDE
(FR) ENDOSCOPE DOTE D'UN GUIDE-IMAGE A EXTREMITE COURBE
Abstract
(EN)
This invention is an endoscope comprising an elongated endoscope body (15) having a distal end (21), an objective (25) carried by the endoscope body adjacent the distal end, and an elongated fiberoptic image guide (27) in the endoscope body for transmitting an image proximally. The objective has a curved proximal surface (51) and the image guide has a curved distal end surface (53) which has a shape that generally conforms to the shape of the curved proximal surface of the objective. These surfaces are in close proximity to provide an interface (33), and an index matching medium (31) is in the interface. The objective (25) provides a curved image plane substantially at the interface, and the image plane has a shape which generally conforms to the shape of the curved proximal surface of the objective.
(FR)
L'invention concerne un endoscope comprenant un corps d'endoscope allongé (15) doté d'une extrémité distale (21), supportant un objectif (25), à proximité de son extrémité distale, et renfermant un guide-image par fibres optiques (27) allongé conçu pour transmettre une image en un point proximal. L'objectif présente une surface proximale courbe (51) et le guide-image une surface d'extrémité distale courbe (53) dont la forme épouse généralement celle de la surface proximale courbe de l'objectif. Ces surfaces sont très rapprochées l'une de l'autre de sorte qu'elles forment une interface (33) dans laquelle est prévu un milieu d'adaptation d'indice (31). L'objectif (25) produit un plan d'image courbe sensiblement au niveau de l'interface, la forme du plan d'image étant généralement adaptée à celle de la surface proximale courbe de l'objectif.
