Device for needle biopsy with integrated needle protection

A needle biopsy device comprising:

• a release member disposed at a proximal end of a handle and comprising an engageable portion that releasably engages a needle housing member disposed within the handle;
• a needle protection hub disposed within the handle and coupled to the needle housing member;
• a needle comprising a protrusion proximate to a distal end of the needle;
• and a needle protection shaft disposed within the handle and coupled to the needle protection hub, wherein the needle protection shaft comprises a lumen with an inner diameter larger than an outer diameter of the protrusion of the needle,
• wherein the protrusion of the needle is slideably disposed within the needle protection shaft as the needle is withdrawn in a proximal direction,
• wherein the protrusion of the needle is configured to traverse a protruded portion disposed within the handle in response to depressing the release member of the handle and withdrawing the needle in the proximal direction such that the protrusion of the needle locks onto a protruded portion of the needle protection hub and the release member disengages from the needle housing member, thereby withdrawing the needle from the lumen of the handle after the release member disengages from the needle housing member.
