Title: (DE) ULTRASCHALLENDOSKOP
(EN) ULTRASONIC ENDOSCOPE
(FR) ENDOSCOPE À ULTRASONS
Abstract: front page image
(EN) An ultrasonic endoscope includes a plurality of ultrasonic vibrators; a distal end part that houses the plurality of ultrasonic vibrators; an electrically conductive endoscopic structure housed in or connected to the distal end part; a thermally conductive member connected to the plurality of ultrasonic vibrators; and an electrically insulating thermally conductive member connected to the endoscopic structure. The thermally conductive member and the electrically insulating thermally conductive member are connected to each other. Thus, the ultrasonic endoscope that has a heat release structure which transmits the heat generated from the ultrasonic vibrators to the electrically conductive endoscopic structure housed in the distal end part and which can efficiently release the heat therefrom while electric safety is secured; and that can prevent a burn of an alimentary canal by suppressing a temperature rise of surfaces of the ultrasonic vibrators is provided.
(FR) L’invention concerne un endoscope à ultrasons comportant: plusieurs transducteurs ultrasonores; une partie (40) extrémité avant dans laquelle sont logés les transducteurs ultrasonores; des éléments de structure d’endoscope électroconducteurs logés dans la partie (40) extrémité avant ou reliés à celle-ci; un élément thermoconducteur (61) relié aux transducteurs ultrasonores; et un élément thermoconducteur isolant (62) relié aux éléments de structure d’endoscope, l’élément thermoconducteur (61) et l’élément thermoconducteur isolant (62) étant reliés. Ainsi, l’endoscope selon l’invention permet, en plus de garantir la sécurité au niveau électrique, de transmettre la chaleur produite dans les transducteurs ultrasonores aux éléments de structure d’endoscope électroconducteurs, lesquels éléments sont logés dans la partie extrémité avant, et, à l’aide d'une structure de dissipation de la chaleur pouvant efficacement dissiper la chaleur, de limiter l’augmentation de la chaleur à la surface des transducteurs ultrasonores et d’éviter les dégâts dus à la chaleur dans le tube digestif.
