(JA) 内視鏡装置
Abstract
(EN)
An endoscope device (1) is provided with a heat absorbing section (55) disposed so as to cover heat sources (42, 43, 45, 46) of an electronic image capturing unit (30) provided within the tip (11) of the endoscope device. The heat generated by the heat sources (42, 43, 45, 46) is absorbed by the heat absorbing section and transferred by a heat transfer section (52). The transferred heat is used to heat an observation window (22), which is disposed at the tip (11), by means of a heat dissipation section (51), and this prevents the misting of the outer surface of an optical member provided at the tip of an insertion section and, in addition, suppresses electrical noise to a captured image.
(FR)
La présente invention concerne un dispositif endoscopique (1) pourvu d'une partie capable d'absorber la chaleur (55), disposée de façon à recouvrir les sources de chaleur (42, 43, 45, 46) d'une unité électronique de capture d'images (30) située au sein de l'extrémité (11) du dispositif endoscopique. La chaleur générée par les sources de chaleur (42, 43, 45, 46) est absorbée par la partie capable d'absorber la chaleur et transférée par une partie capable de transférer la chaleur (52). La chaleur transférée est utilisée pour réchauffer un hublot d'observation (22), disposé au niveau de l'extrémité (11), grâce à une partie capable de dissiper la chaleur (51), cela évitant l'embuage de la surface extérieure d'un élément optique disposé à l'extrémité d'une partie servant à l'introduction et éliminant, en outre, le bruit électrique affectant les images capturées.
