Robotic surgery systems are highly complex and expensive pieces of equipment. Demands for lower cost of care can be met if these systems are employable in a flexible manner for a large variety of procedures. To protect the initial investment the capabilities of a robotic system need to be expandable as new tasks arise. To oblige the needs of future robotic support in hospitals, the German Aerospace Center (DLR) has developed the versatile robotic system MiroSurge for medical applications. This paper presents a 3 DoF instrument for Minimally Invasive Robotic Surgery which is mounted to the hollow wrist of the DLR MIRO robot arm. The MICA instrument consists of a versatile drive train and a detachable task specific tool with its tool interface, shaft, 2 DoF wrist, 7 DoF force/torque sensor and the actuated functional end. With the current cable-driven tool, gripping and manipulation forces of above 10 N are feasible and dynamics is high enough for surgery at the beating heart.
