Abstract

A biopsy needle guide in accordance with the invention is configured for attachment to an ultrasound transducer. The biopsy needle guide is arranged in two sections, an inner attachment block and an outer attachment block. The inner attachment block includes (i) a coupler which attaches the inner attachment block to the ultrasound transducer and (ii) a first engagement structure which extends from a surface thereof. The outer attachment block includes a biopsy needle guide through hole and a second engagement structure. The second engagement structure releasably mates with the first engagement structure even when the inner attachment block is covered by a sterile film sheath.
