The invention is directed to a system and device for separating and collecting a tissue specimen from a patient target site. The device includes a probe component (11) with an elongated tubular section (15), a penetrating distal tip (16) and a tissue receiving aperture (17) in the distal end of the tubular section proximal to the distal tip, and a tissue cutting member (20) which is slidably disposed within the probe member to cut a tissue specimen drawn into the interior of the device through the aperture by applying a vacuum to the inner lumen of the tissue cutting member. The device has a driver component (12) to which the probe component is releasably secured. The driver has a drive member (22,23) for adjusting the orientation of the tubular section and one or more drive members (30) for moving the tissue cutting member within the tubular section to sever a tissue specimen. The motion imparted to the tissue cutter is at least longitudinal and preferably is also oscillation and/or rotational.
L'invention porte sur un système et sur un dispositif de séparation et prélèvement d'un échantillon de tissu d'un patient. Le dispositif comporte: une sonde à section tubulaire allongée; un embout distal de pénétration comportant l'ouverture de l'extrémité distale de la section tubulaire située en amont de l'embout distal; et un élément de découpage du tissu coulissant dans la sonde et découpant échantillon de tissu aspiré à l'intérieur du dispositif via l'ouverture par application d'un vide à la lumière intérieure de l'élément de découpage. Le dispositif comporte également une commande comprenant un élément d'orientation de la section tubulaire et donc de son ouverture, et un élément entraînant l'élément de découpage pour détacher l'échantillon du tissu et s'étendant à l'intérieur de la section tubulaire via l'ouverture. Le mouvement communiqué à l'élément de découpage est au moins longitudinal de également de préférence d'oscillation et/ou de rotation.
