Abstract
A medical system includes a flexible elongate instrument and a control unit. The control unit is configured to determine a force exerted by the flexible elongate instrument on tissue of a patient, determine a driving state of the flexible elongate instrument, set a force threshold based on the driving state, and provide feedback to an operator in response to the determined force being higher than the force threshold. Different driving states are associated with different force thresholds.
