An ultrasonic probe comprises an element section (1) for transmitting/receiving an ultrasonic wave, a relay cable (2) connected to the element section (1), and an oscillating mechanism section for oscillating the element section (1). The cross section of the relay cable (2), perpendicular to the rotation axis (3) of the oscillation of the element section (1) by the oscillating mechanism section, has a shape comprising two or more arc portions smoothly connected to each other, specifically has an S-letter shape or an inverted S-letter shape. The relay cable (2) is led out from the side of the oscillation axis (3) of the element section (1). Thus, the stress on the relay cable (2) can be dispersed during the oscillation of the element section (1), thereby improving the durability of the relay cable (2).
L'invention concerne une sonde ultrasonore comprenant un élément (1) destinée à transmettre/émettre une onde ultrasonore, un câble relais (2) relié à cet élément (1), et un mécanisme d'oscillation destinée à faire osciller l'élément (1). La section transversale du câble relais (2), perpendiculaire à l'axe de rotation (3) d'oscillation de l'élément (1) au niveau du mécanisme d'oscillation, possède une forme comprenant deux ou plusieurs parties arquées uniformément connectées les unes aux autres, et plus particulièrement, une forme de S ou de S inversé. Le câble relais (2) est dérivé du côté de l'axe d'oscillation (3) de l'élément (1). Ainsi, la contrainte sur le câble relais (2) peut être répartie durant l'oscillation de l'élément (1), améliorant ainsi la durabilité du câble relais (2).
