Abstract
(EN)
A tissue sampling device, comprising a stylet having a notch therein and a cannula at least partially surrounding the stylet. The notch has an exposed portion for receiving tissue to be sampled, and the cannula is adjustable relative to the stylet to vary the size of the exposed portion and therefore the amount of tissue to be sampled. The device also comprises a trigger mechanism operatively connected to at least one of the cannula and the stylet. Acutation of the trigger mechanism causes relative movement of the stylet with respect to the cannula for collection of a tissue sample.
(FR)
L'invention concerne un dispositif d'échantillonnage de tissus comprenant un stylet muni d'une encoche et une canule entourant au moins partiellement le stylet. L'encoche comprend une partie exposée destinée à recevoir le tissu à échantillonner tandis que la canule peut être réglée par rapport au stylet de manière à modifier la taille de la partie exposée et, par conséquent, la quantité de tissu à échantillonner. Ce dispositif comprend également un mécanisme de détente relié de manière fonctionnelle à la canule et/ou au stylet. L'actionnement du mécanisme de détente provoque un mouvement du stylet par rapport à la canule, de manière à prélever un échantillon de tissu.
