Abstract
A method for calibrating a surgical biopsy system. The biopsy system includes a biopsy instrument and control unit. The biopsy instrument includes a piercer, rotatable cutter, and a port for receiving tissue samples. The method comprises the steps of translating the cutter display until the translation of the cutter is stopped at an extended position and recording the extended position. The cutter is then translated from the extended position proximally until the translation of the cutter is stopped at a retracted position proximal to the extended position. The retracted position is recorded. The method further comprises the step of rotating the cutter to a rotation speed while the cutter is located at the retracted position and, if determined that the rotation speed is within a predetermined rotation speed range, a feedback signal is provided on the display allowing the operator to progress to the next procedural step.
