MRI compatible surgical biopsy device

摘要

A biopsy device which is compatible for use with a magnetic resonance imaging machine. The device includes a non-metallic elongated substantially tubular needle having a distal end for insertion within tissue, a proximal end, and a longitudinal axis therebetween. The needle includes right and left members on either side of the longitudinal axis, where the right and left members each have upper and lower ends including a series of alternating male and female portions. The male portions of the right member mate with the female portions of the left member, and the male portions of the left member mate with the female portions of the right member to securely attach the two members together. The device further includes a port on the elongated needle for receiving a tissue sample.
