1. An introducer needle apparatus, comprising:
an introducer needle having a canal;
a hub connected to the introducer needle along a distal end of the hub and providing an interior space being in fluid communication with the canal of the introducer needle, the hub including a releasable lock at a proximal end of the hub to mate with a coaxial biopsy device while the coaxial biopsy device is positioned through the canal of the introducer needle;
a one-way valve having a circular periphery engaged with and extending inwardly from a cylindrical interior wall of the interior space of the hub so that the one-way valve is configured to both flexibly open to a diameter greater than the canal of the introducer needle during insertion of the coaxial biopsy device through the hub and prevent a backflow of a fluid from a patient's body toward the proximal end of the hub during withdrawal of the coaxial biopsy device from the introducer needle and the hub; and
the coaxial biopsy device matable with the hub and configured for coaxial insertion through the canal of the needle for a soft tissue biopsy or bone biopsy, wherein the coaxial biopsy device comprises a biopsy gun at a proximal end and a biopsy needle extending distally from the biopsy gun.
