#$%^&*AU2007203248B220120524.pdf#####ABSTRACT A biopsy device and method are provided for obtaining a tissue sample, such as a breast tissue biopsy sample. The biopsy device includes a disposable probe assembly with an outer cannula having a distal piercing tip, a cutter lumen, and a cutter tube that rotates and translates past a side aperture in the outer cannula to sever a tissue sample. The biopsy device also includes a reusable handpiece with an integral motor and power source to make a convenient, untethered control for use with ultrasonic imaging. The reusable handpiece incorporates a probe oscillation mode to assist when inserting the distal piercing tip into tissue. The motor also actuates a vacuum syringe in coordination with movement of the cutter tube to provide vacuum assistance in prolapsing tissue and retracting tissue samples.1/21 co co 0 ff-) 00 CD 0 co 0 (D (D
