Abstract
A teleoperable medical system comprises a manipulator arm and a cannula mount coupled to the manipulator arm. The manipulator arm comprises an interface configured to operably couple with a medical instrument. The cannula mount is configured to removably mount a cannula to the manipulator arm in a position to permit removable insertion of the medical instrument through the cannula. The cannula mount comprises a receptacle configured to receive an attachment portion of the cannula in a mounted state of the cannula, and a reader positioned to be in magnetic field sensing proximity to the attachment portion of the cannula in the mounted state of the cannula. The teleoperable medical system comprises a controller configured to receive output signals from the reader and determine identification information about the cannula based on the output signals.
