Title (EN) BIOPSY DEVICE WITH RETRACTABLE CUTTER
(FR) DISPOSITIF DE BIOPSIE AVEC CISAILLE RÉTRACTILE
Abstract:
(EN) A biopsy device comprises a targeting set assembly (23), a probe assembly (18), and a holster assembly (20), which are detachable from one another. The targeting set assembly comprises a needle assembly (29) having a tissue piercing tip (212), a tissue receiving aperture (278), and a fluid sealing mechanism. The probe assembly comprises a tissue cutter (107) and an internal helix mechanism (282). The internal helix mechanism may fully retract the cutter within the probe assembly to prevent exposure to the sharp distal end of the cutter when the probe assembly is detached from the needle assembly. When the probe assembly and needle assembly are connected, the internal helix mechanism may extend the cutter into the needle to facilitate biopsy of a tissue sample. The helix may have a variable pitch (294) for providing a first translational speed for cutting with the cutter and a second translational speed for cutter retraction.
(FR) L'invention concerne un dispositif de biopsie comprenant un ensemble de ciblage (23), une sonde équipée (18) et un ensemble holster (20), qui sont amovibles l'un de l'autre. L'ensemble de ciblage comprend un ensemble aiguille (29) possédant une pointe (212) pour percer les tissus, une ouverture (278) de réception des tissus, et un mécanisme d'étanchéité au fluide. La sonde équipée comprend une cisaille (107) pour tissus et un mécanisme hélicoïdal interne (282). Le mécanisme hélicoïdal interne peut entièrement rétracter la cisaille dans la sonde équipée pour empêcher toute exposition à l'extrémité distale tranchante de la cisaille lorsque la sonde équipée se détache de l'ensemble aiguille. Lorsque la sonde équipée et l'ensemble aiguille sont connectés, le mécanisme hélicoïdal interne peut déployer la cisaille dans l'aiguille pour faciliter la biopsie d'un échantillon de tissu. L'hélice peut présenter un pas variable (294) assurant une première vitesse translationnelle permettant de découper à l'aide de la cisaille et une seconde vitesse translationnelle pour la rétraction de la cisaille.
