COMPUTER-ASSISTED MEDICAL SYSTEMS AND METHODS

A computer-assisted medical system includes a manipulator, an instrument holder physically coupled to the manipulator arm, and a controller that includes a computer processor. The instrument holder includes an instrument holder carriage configured to releasably couple to an instrument and translate the instrument along a longitudinal axis. The controller applies a signal that represents a movement for the instrument along the longitudinal axis to a filter to differentiate between a first and a second motion component of the movement along the longitudinal axis, and causes the instrument to move in accordance with the movement along the longitudinal axis by commanding the manipulator arm to move based on the first motion component of the movement along the longitudinal axis. The controller further commands, based on the second motion component of the movement along the longitudinal axis, the instrument holder carriage to move relative to the manipulator arm.
