Core sampling biopsy device with short coupled MRI-compatible driver
A core sampling biopsy device is compatible with use in a Magnetic Resonance Imaging (MRI) environment by being driven by either a pneumatic rotary motor or a piezoelectric drive motor. The core sampling biopsy device obtains a tissue sample, such as a breast tissue biopsy sample, for diagnostic or therapeutic purposes. The biopsy device may include an outer cannula having a distal piercing tip, a cutter lumen, a side tissue port communicating with the cutter lumen, and at least one fluid passageway disposed distally of the side tissue port. The inner cutter may be advanced in the cutter lumen past the side tissue port to sever a tissue sample. A cutter drive assembly maintains a fixed gear ratio relationship between a cutter rotation speed and translation speed of the inner cutter regardless of the density of the tissue encountered to yield consistent sample size.
