Abstract

Le problème à la base de l'invention concerne l'introduction correcte d'une aiguille de ponction dans une position souhaitée sur une ligne de balayage d'une sonde ultrasonore sans nécessiter de trou de guidage. La solution porte sur un adaptateur (1) de ponction fixé à une sonde ultrasonore comprenant une pièce principale (10) qui s'étend dans la direction verticale et une sous-pièce (20) positionnée sur la face avant (10a) de la pièce principale, la pièce principale et la sous-pièce étant liées. La pièce principale comporte, sur la surface avant, au-dessous du site de liaison avec la sous-pièce, une partie (11) de surface de miroir qui s'étend dans la direction verticale. La sous-pièce présente une partie inclinée (21) qui est inclinée vers le bas par rapport à la surface avant de la pièce principale et une première fente (22) formée dans la partie inclinée. Il est possible de reconnaître visuellement la partie de surface du miroir à travers la première fente.
