Systems and methods for homing an automated biopsy driver for installing a disposable biopsy needle assembly

An automated biopsy system, comprising:

• a motorized driver having a first drive member for actuating a first biopsy needle assembly removably installed on the motorized driver, the first drive member configured to operatively couple with a first needle interface of a biopsy needle assembly removably installed on the motorized driver, the motorized driver configured to actuate the first drive member to thereby actuate the first biopsy needle assembly via the first needle interface;
• a user interface having a display and a user input device configured to receive user commands;
• a controller operatively coupled with each of the motorized driver and user interface, wherein the controller is configured to control operation of the motorized driver including performing a homing process comprising
• determining a system test failure or a needle removal condition in which the first biopsy needle assembly installed on the motorized driver either has been or should be removed from the motorized driver and reinstalled or replaced with a second biopsy needle assembly,
• after determining the system test failure or needle removal condition, displaying a message on the user interface display prompting a user to select, through the user interface, whether to install a second biopsy needle assembly or reinstall the first biopsy needle assembly,
• upon receiving a user selection to install the second biopsy needle assembly, performing a driver homing comprising operating the motorized driver to position the first drive member in a first drive member home position for receiving the second biopsy needle assembly, wherein the second biopsy needle assembly is configured to be installed on the motorized driver with the first needle interface in the first needle home position, and
• upon receiving a user selection to reinstall the first biopsy needle assembly, leaving the first drive member in a same position as when the first biopsy needle was removed.

An automated biopsy system, comprising:

• a motorized driver configured to have a biopsy needle assembly removably installed thereon, and
• a controller operatively coupled with the motorized driver, wherein the controller is configured to
• determine a system test failure or a needle removal condition in which a first biopsy needle assembly installed on the motorized driver has been or should be removed from the motorized driver, and
• after determining the system test failure or needle removal condition, perform a driver homing comprising operating the motorized driver to position a first drive member of the motorized driver at a first drive member home position for receiving a second biopsy needle assembly to be removably installed on the motorized driver.
