The invention provides a device for needle biopsy having a novel delivery handle system for interchangeably delivering needles of various sizes to a biopsy site. The delivery handle system is adjustable in length and includes a proximal handle member slideably disposed over a middle handle member, and the middle handle member is slideably disposed over a distal handle member. The proximal handle member includes an inner hub housing component configured to interchangeably receive a needle subassembly that can be inserting into and withdrawn from the proximal handle member. The needle subassembly includes a needle of a plurality of different sizes, a needle luer, a needle hub coupled to a proximal end portion of the needle, and a needle protector subassembly. The needle protector subassembly includes a needle protection hub configured to receive the distal end of a needle. |
