MRI BIOPSY TARGETING CUBE WITH RETENTION WIPER

摘要

A biopsy system comprises a localization assembly, a biopsy device, and a targeting cube. At least a portion of the biopsy device is insertable through a targeting cube, which is insertable into a selected aperture of a grid plate. The targeting cube comprises a body defined by faces, with guide passageways that originate and terminate at the faces and pass through the body of the targeting cube to accommodate insertion of a part of the biopsy device. An exterior wiper retainer of the targeting cube engages the grid plate to permit insertion of the targeting cube into a selected aperture of the grid plate while resisting withdrawal of the targeting cube from the grid plate. Internal wiper retainers in the guide passageways permit insertion of part of the biopsy device through a selected guide passageway while resisting withdrawal of the inserted part from the targeting cube.
