Abstract

La présente invention concerne une aiguille pour biopsie par aspiration à l'aiguille fine guidée par ultrasons. Plus spécifiquement, l'aiguille comprend : une enveloppe tubulaire (1) ayant une partie d'insertion (101) formée sur une partie d'extrémité de celle-ci, la partie d'insertion comprenant une surface inclinée (101a) ; une partie de collecte de tissu (2) ayant des lames de collecte de tissu (202) formées sur des côtés opposés d'un évidement de collecte de tissu (201) qui est formé sur un côté d'une paroi principale de l'enveloppe (1) dans une direction perpendiculaire à la direction longitudinale de l'enveloppe (1) ; une partie d'écho (3) ayant une rainure en spirale (301) formée sur la surface périphérique externe de l'enveloppe (1), la rainure en spirale (301) formée sur une section orientant la direction longitudinale de l'enveloppe étant formée en zigzags. Par conséquent, la présente invention peut augmenter une force et une résistance de collecte de tissu de façon à réduire le temps nécessaire pour une biopsie par aspiration à l'aiguille fine guidée par ultrasons, et peut éviter d'endommager une aiguille, par exemple par flexion ou rupture, dans une procédure chirurgicale.
