(FR) SONDE ULTRASONORE ET ENDOSCOPE ULTRASONORE DOTÉ D'UNE SONDE ULTRASONORE
Abstract
(EN)
Disclosed herein is to allow a reduction in diameter of an ultrasound probe and an ultrasound endoscope and allow reliable and easy electrical connection of signal lines extending from ultrasound transducers. A transducer wiring pad group 102 provided in a distal end portion of an ultrasound transducer printed circuit board 101 provided with signal patterns that transmit and receive signals to and from a plurality of ultrasound transducers, a flexible printed circuit board wiring pad group 108 arranged in a longitudinal axis direction of the ultrasound transducer printed circuit board 101, a second signal pattern group 106 that is connected between the transducer wiring pad group 102 and the flexible printed circuit board wiring pad group 108 and bends at substantially 90 degrees in the middle thereof, and a relay flexible printed circuit board 121 that is connected to the flexible printed circuit board wiring pad group 108 and changes a direction of a signal pattern into the longitudinal axis direction are provided.

(FR)
Les diamètres d'une sonde ultrasonore et d'un endoscope ultrasonore sont moindres, et un raccord électrique sur une ligne de signal s'étendant à partir du vibrateur ultrasonore est effectué de façon facile et fiable. La sonde ultrasonore comprend des plots (102) de câblage de vibrateur disposés à l'extrémité avant d'une plaque à circuits imprimés (101) de vibrateur ultrasonore où sont formés des motifs de signaux pour une transmission/réception de signal de vibrateurs ultrasonores; des plots de câblage de la plaque à circuits imprimés flexible (108) disposés en alignement le long de l'axe longitudinal de la plaque à circuits imprimés (101) de vibrateur ultrasonore; des seconds motifs de signaux (106) raccordés entre les plots de câblage du vibrateur (102) et les plots de câblage de la plaque à circuits imprimés flexible (108) et repliés généralement de 90 degrés à des espaces intermédiaires; et une plaque à circuits imprimés flexible de relais (121) raccordée aux plots de câblage de la plaque à circuits imprimés flexible (108) et utilisée pour changer la direction des motifs de signaux et les faire passer dans la direction de l'axe longitudinal.
