M3 Systems

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.

Automatic tissue sampling apparatus

An apparatus for the automated and facilitated handling and operation of a biopsy needle system, having a first inner needle component and a second outer needle component. 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.

A spacer clip apparatus, for use with a biopsy needle, having first inner and second outer needle components, is provided. The first inner and second outer needles are provided with first and second handles, respectively. The spacer clip apparatus includes a pair of splines, which extend parallel to and in opposite directions away from opposite sides of a stem. Hook members placed at the ends of the splines, remote from the stem, frictionally engage the respective first and second handles of the first inner and second outer needles.
