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 hand piece with an integral motor and power source to make a convenient, untethered control for use with ultrasonic imaging. External vacuum holes along the outer cannula (probe) that communicate with a vacuum and cutter lumen withdraw bodily fluids while a hemostatic disk-shaped ring pad around the probe applies compression to an external hole in the skin and absorbs fluids.
