Abstract: A method of operating a minimally invasive medical system, including positioning a tip of a surgical instrument through an incision into a body cavity, the surgical instrument having an instrument shaft with a longitudinal instrument axis, mounting the surgical instrument to a manipulator, the manipulator including a force/torque sensor, moving the minimally invasive instrument along a first axis and a second axis, each of the first and second axes perpendicular to the instrument axis, until a reaction force along each axis is below a given threshold, and defining and axis coordinates of the external fulcrum at a location where the reaction forces along both axes are below the given threshold, and determining an axis coordinate position of the external fulcrum along the instrument axis by pivoting the instrument with respect to its tip until a sufficient contact force is reached, and determining the axis coordinate position using the lever principle.

Abstract: A method of force estimation for a minimally invasive medical system comprising a robot manipulator (10). The manipulator has an effector unit (12) equipped with a 6-degrees-of-freedom (DOF) force/torque sensor and is configured to hold a minimally invasive instrument (14) having a first end (16) mounted to the effector unit and a second end (20) located beyond an external fulcrum (23) that limits the instrument in motion, usually to 4 DOF. The method comprising the steps: determining a position of the instrument relative to the fulcrum; measuring by means of the 6-DOF force/torque sensor a force and a torque exerted onto the effector unit by the first end of the instrument; and calculating by means of the principle of superposition an estimate of a force exerted onto the second end of the instrument based on the determined position, the measured force and the measured torque.
