Abstract
(EN)
This endoscopic imaging device (1) comprises: an image capture element (10) for outputting an image capture signal; a drive IC (21) for outputting a drive signal adapted to the image capture signal; a light-emitting element (30) for converting the drive signal into an optical signal and sending out the optical signal from a light-emitting surface (30SA); an optical fiber (61) for transmitting the optical signal; a flexible tube (62) whereinto the optical fiber (61) has been inserted; a ferrule (50) having an insertion hole (H50) whereinto the tube (62) and the optical fiber (61) have been inserted. The fiber leading end portion of the optical fiber (61) protrudes from the tube leading end portion of the tube (62), and a transparent resin (70) covering the fiber leading end portion is further provided.

La présente invention concerne un dispositif d’imagerie endoscopique (1) comprenant : un élément de capture d’image (10) permettant d'émettre un signal de capture d’image ; un circuit intégré d’attaque (21) permettant d'émettre un signal d’entraînement adapté au signal de capture d’image ; un élément d’émission de lumière (30) permettant de convertir le signal d’entraînement en un signal optique et d'émettre le signal optique depuis une surface d’émission de lumière (30SA) ; une fibre optique (61) permettant de transmettre le signal optique ; un tube souple (62) dans lequel la fibre optique (61) a été insérée ; un férule (50) comportant un trou d’insertion (H50) dans lequel le tube (62) et la fibre optique (61) ont été insérés. La partie d’extrémité avant de fibre de la fibre optique (61) fait saillie depuis la partie d’extrémité avant de tube du tube (62), et une résine transparente (70) recouvrant la partie d’extrémité avant de fibre est en outre prévue.
