MRI compatible biopsy device with detachable probe

A Magnetic Resonance Imaging (MRI)-guided core biopsy system, comprising:

• a core biopsy probe assembly;
• an MRI breast coil including a localization fixture comprising:
• a compression plate having apertures, and
• a mounting device operably configured to connect to the probe assembly at a selected orientation to the compression plate and to guide the probe assembly in depth as inserted through a selected aperture;
• a cutter device selectably attachable to the probe assembly to advance a cutter through the probe assembly to cut a tissue sample;
• a control module operable to generate a translation motion and a rotation motion;
• and
• a power cable connecting the translation motion and the rotation motion from the control module to the cutter of the cutter device.

A core biopsy probe comprising:

• an elongated substantially tubular needle having a distal end for insertion within tissue, a proximal end, and a longitudinal axis therebetween, the needle separated along the longitudinal axis into a cutter lumen and a vacuum lumen, a cutter opening laterally placed near the distal end of the cutter lumen and in fluid communication with the vacuum lumen;
• and
• an engagement device coupled to the proximal end of the needle, the engagement device including a cutter access port aligned to the longitudinal axis of the needle;
• and a vacuum port in fluid communication with the vacuum lumen, the engagement device further including a attachment member transversely disposed to the longitudinal axis and configured to attach to a mounting device for maintaining a position of the probe with respect to a biopsy site location.
