Abstract

A method is provided 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 distally 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.

Claims

1. A method for calibrating a biopsy system comprising the steps of:

providing a control unit operable to control a biopsy probe having an elongated hollow piercer having a lateral tissue receiving port, and a cutter rotatable and axially translatable relative to the lateral tissue receiving port;

prompting the operator of the biopsy system to select a probe size;

translating the cutter;

determining the distance traveled by the cutter by calculating the distance between a cutter position proximal of the tissue receiving port and a cutter position distal of the tissue receiving port; and

comparing a distance traveled by the cutter to a value associated with the selected probe size.

2. The method of claim 1 further comprising recording a position of the cutter.

3. The method of claim 2 comprising recording multiple positions of the cutter.

4. The method of claim 1 further comprising the step of providing a message to the operator if the distance traveled by the cutter is not within a predetermined range.

5. The method of claim 1 wherein the step of prompting the operator comprises prompting the operator to select an icon on a display.

6. A method for calibrating a biopsy system comprising the steps of:

providing a control unit operable to control a biopsy probe having an elongated hollow piercer with a lateral tissue receiving port and a cutter rotatable and axially translatable relative to the lateral tissue receiving port;

providing a display for communicating information to the operator of the biopsy probe;

prompting the operator to select a probe size via the display;

translating the cutter between a position proximal of the tissue receiving port and a position distal of the tissue receiving port;

determining the distance traveled by the cutter in translating between the position proximal of the tissue receiving port and the position distal of the tissue receiving port; and

comparing the distance traveled by the cutter to a value associated with the selected probe size.
