Abstract
(EN)
A needle guiding system (10) for guiding a needle (12) into a patient. The system includes an ultrasonic scanning apparatus (14) having a scan plane (16) and a central ray (18). The system includes a needle guide (20) having a slot (22) which receives the needle. The slot has a first side (24) and an opposed second side (26). The needle is free to move in a path within an arc (18) of at least $g(p)/16 in the slot, but the needle is prevented from moving in a direction between the first side and the second side by the first side and second side.

L'invention concerne un système de guidage d'aiguille (10) destiné à guider une aiguille (12) dans un patient, comprenant un appareil à balayage par ultrasons (14) présentant un plan d'exploration (16) et un rayon central (18). Le système comprend un guide-aiguille (20) présentant une fente (22) destinée à recevoir l'aiguille, ladite fente présentant un premier côté (24) et un second côté, opposé (26). L'aiguille est libre de se déplacer sur un parcours à l'intérieur d'un arc (18) d'au moins $g(p)/16 dans la fente, mais est empêchée de se déplacer dans une direction comprise entre le premier côté et le second côté, par le premier côté et le second côté.
