A retractable centesis needle comprises a hollow, sharp tipped outer cannula extending from a housing. The outer cannula is generally tube-like and open at both ends to form a channel into a cavity in the housing. A blunt tipped inner cannula is disposed within the channel and capable of sliding away from the housing to an extended state and toward the housing to a refracted state. The inner cannula is biased toward the extended state by a first spring disposed in the housing. A second spring also disposed in the housing acts in the same direction as the first spring when the inner cannula is in a fully retracted state. However, the second spring does not bias the inner cannula in any direction when the inner cannula is in a fully extended state.

An apparatus for the automated and facilitated handling and operation of a biopsy needle system, having a first needle component and a second needle component. The first and second needles are provided with first and second handles, respectively, which are fitted into first and second yokes of the apparatus. The apparatus is configured to maintain the first and second needles in a first position, during insertion of the biopsy needle point into the tissue being sampled. The apparatus is further configured to forwardly move the first and second needles into subsequent positions, respectively, in rapid, automated succession so as to segment and enclose a tissue sample, which may be tested after removal of the biopsy needle system from the tissue. A tissue sample inspection feature permits facilitated repositioning and maintenance of the first needle relative to the second needle after retrieval of the tissue sample to, in turn, enable inspection of the retrieved tissue sample without removal of either needle from the apparatus. The apparatus is further configured so as to be actuatable from positions adjacent the front or the rear of the apparatus housing. A safety lock feature is provided, which prevents inadvertent cocking motions, when the apparatus is actuated by either its rear or forward firing buttons.

An integrated biopsy needle assembly for use with a conventional biopsy gun comprises a hollow cannula, a stylet, a cannula hub operatively fixed to the proximal end of the cannula, a stylet hub operatively fixed to the proximal end of the stylet, and a hub strap operably associated therewith. The cannula hub is operatively fixed to the hub strap, while the stylet hub is capable of movement relative to the hub strap. The hub strap includes a top member, at least one side wall and at least one bottom member, thereby forming an inner channel. The cannula and stylet hubs further include a base and a cap, with the cannula and stylet hub caps being maintained at all times within the inner channel of the hub strap.

The first inner and second outer needles are provided with first and second handles, respectively, which are fitted into first and second yokes of the apparatus. The apparatus is configured to maintain the first inner and second outer needles in a first position, during insertion of the biopsy needle point into the tissue being sampled. The apparatus is further configured to move the first inner and second outer needles into second and third positions, respectively, in rapid, automated succession so as to segment and enclose a tissue sample, which may be tested after removal of the biopsy needle system from the tissue. A tissue sample inspection feature permits facilitated repositioning and maintenance of the first inner needle relative to the second outer needle after retrieval of the tissue sample to, in turn, enable inspection of the retrieved tissue sample without removal of either needle from the apparatus.
