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

Abstract:

A biopsy system includes a motorized driver having a drive member operatively coupled with a needle interface of a biopsy needle assembly that is removably installed on the motorized driver, wherein the motorized driver actuates the drive member to thereby actuate the biopsy needle assembly via the needle interface. A system controller that controls operation of the motorized driver is configured to perform a homing process including determining a system test failure or a needle removal condition in which a biopsy needle assembly installed on the motorized driver has been or should be removed from the motorized driver. Upon determining a system test failure or needle removal condition, the controller positions the drive member in a drive member home position for receiving a new biopsy needle assembly to be installed on the motorized driver.
