  • Publication number: 20100152610
    Abstract: A hand actuated biopsy device comprises a vacuum generation mechanism and a tissue cutting mechanism manually actuated by a trigger of the hand actuated biopsy device. Hand manipulation or actuation of the trigger is used to power a vacuum pump to generate vacuum and to power the tissue cutting mechanism. The hand actuated biopsy device has a tissue piercing needle with a tissue receiving aperture. A tissue cutter translates and rotates within the needle and is powered by actuations of the trigger. When the needle is placed into tissue and the trigger is actuated to power the vacuum pump and the tissue cutter, tissue is drawn into the tissue receiving aperture and severed by the hand powered cutter. A tissue collection chamber can be attached to the hand actuated biopsy device to receive severed tissue samples within.

  • Publication number: 20100152611
    Abstract: A biopsy device includes a body having a cannula, a cutter positioned at least partly within the cannula, a tissue collection chamber, and a vacuum source. In one example, the biopsy device includes a cutter loader for rotating the cutter into a loaded position (e.g., open position). A trigger is engaged with a portion of the cutter loader and may be activated to allow the cutter to rotate back to a closed position. During this rotation, the cutter severs a tissue sample, which may thereafter be drawn through the cutter lumen into the tissue collection chamber under the influence of a vacuum created by the vacuum source. The vacuum source includes a piston configured to be operated by squeezing a scissors grip. A user may apply a single stroke or successive strokes to the piston to produce the vacuum.

  • Publication number: 20090318832
    Abstract: A biopsy device comprises a probe that is configured to couple with a holster. The probe comprises a needle, a cutter, and a body portion. The needle is rotatable and translatable relative to the body portion. The holster has a locking feature that is configured to prevent the needle from rotating relative to the body portion upon coupling of the probe with the holster. The locking feature may also be configured to prevent the needle from translating relative to the body portion upon coupling of the probe with the holster. The same probe may thus be used with a holster intended for use in a fixture-based, stereotactic setting, in which rotation and translation of the needle may be desired; and with a holster intended for use in a handheld, ultrasound-guided setting, in which rotation and translation of the needle may be less desired if not undesirable.
