摘要：
A biopsy device having a translating and rotating cutter is disclosed. The translational speed of the cutter is varied using a variable pitch member. The variable pitch member can include a shaft having a relatively coarse threaded portion for rapid cutter advance and a relatively finer threaded portion for cutter advance during tissue severing.
