Title
(EN) TISSUE BIOPSY NEEDLE DEVICE
(FR) DISPOSITIF A AIGUILLE POUR BIOPSIE TISSULAIRE
(JA) 組織生検針装置
Abstract
(EN)
A tissue biopsy needle device having a protective cover preventing a needle tube from being unnecessarily ejected when an urging member for ejecting the needle tube is compressed. The tissue biopsy needle device has a spring (28) that ejects the needle tube (26); a pulling knob (20) and a pulling means of a pulling tube section (29) that pull and move the spring (28) to a compressed position; an operation switch (24) that holds the spring (28) after it is pulled and moved to the compressed position by the pulling means and releases the spring (28) from the compressed position to eject the needle tube (26); the protective cover (23) that brings the operation switch (24), which holds the spring (28) after it is pulled and moved to the compressed position by the pulling means, to a non-operation state; and an elastic tongue member (23c) provided on the protective cover and a contact member (29b) of the pulling tube section (29) that move, as the spring (28) is pulled and moved to the compressed position by the pulling means, the protective cover (23) from a position at which the operation switch (24) is operable to a position at which it is inoperable.

L’invention concerne un dispositif à aiguille pour biopsie tissulaire, comportant une coiffe de protection empêchant l’éjection intempestive d’un tube d’aiguille lors de la compression d’un élément de poussée servant à éjecter le tube d’aiguille. Le dispositif à aiguille pour biopsie tissulaire comporte un ressort (28) qui éjecte un tube d’aiguille (26) ; un bouton de traction (20) et un moyen de traction d’une partie de tube de traction (29) qui tire sur le ressort (28) pour le placer dans une position comprimée ; un commutateur fonctionnel (24) qui maintient le ressort (28) dans sa position comprimée par le moyen de traction et libère le ressort (28) de sa position comprimée pour éjecter le tube d’aiguille (26) ; une coiffe de protection (23) qui place le commutateur fonctionnel (24), lequel maintient le ressort (28) dans sa position comprimée par le moyen de traction, dans un état non fonctionnel ; et un élément à languette élastique (23c) formé sur la coiffe de protection et un élément de contact (29b) formé sur la partie de tube de traction (29) qui, lorsque le moyen de traction tire sur le ressort (28) pour le placer dans sa position comprimée, déplacent la coiffe de protection (23) d’une position dans laquelle le commutateur fonctionnel (24) est actionnable à une position dans laquelle il n’est pas actionnable.
