1. An operation assistance system for medical interventions or operations, composed of a base unit and robotic kinematics connected thereto, the robotic kinematics comprising: a support column having a lower end section that is pivotally mounted about a first pivotal axis (SA1) on the base unit and controlled by a first drive unit, at least a first robotic arm and a second robotic arm, wherein a first end section of the first robotic arm is pivotally mounted about a second pivotal axis (SA2) on an upper end section of the support column opposite to the base unit and controlled by a second drive unit and a first end section of the second robotic arm is pivotally mounted about a third pivotal axis (SA3) on a second end section of the first robotic arm by a third drive unit, wherein the first drive unit, the second drive unit and the third drive unit are controlled via at least one control unit and the first pivotal axis (SA1) is perpendicular to the second and third pivotal axes (SA2, SA3), wherein each of the first drive unit, the second drive unit and the third drive unit are respectively associated with a controllable magnetic brake unit by which the robotic kinematics is selectively uncoupled from the first drive unit, the second drive unit and the third drive unit in an uncoupled state. |
