Abstract
A method of operating a biopsy device includes providing a sampling mode for taking a tissue sample with a biopsy needle; providing an insertion/removal mode for inserting or extracting the biopsy needle from living tissue; displacing a primary drive member through a continuous range that defines a first interval and a second interval; transmitting a motive force via the primary drive member to a first drive element during the first interval to cause a pump to generate a vacuum in the biopsy needle; and, transmitting a motive force via the primary drive member to a second drive element during the second interval to change the biopsy needle from the insertion/removal mode to the sampling mode.
