Abstract
A driver apparatus is provided for use with a biopsy instrument, the driver apparatus including a housing and an insertion mechanism including a carriage movably associated with the housing and adapted to support the biopsy instrument to affect longitudinal movement of at least a portion of the biopsy instrument. A linear motion control mechanism is also included that is adapted to move a tissue cutting element of the biopsy instrument from a first position to a second position relative to a tissue receiving portion of the biopsy instrument. Further, a tissue retract mechanism is included which facilitates removal of a tissue specimen from the biopsy instrument without removing the entire biopsy instrument from a surgical site.
