A medical manipulator system includes an operation unit that has motors, a composite input unit and a tip operating unit that is operated by a driving force of the motors, a working unit that may by attached to and detached from the operating unit, and a console. The motors are driven based on an input operation to the composite input unit. The tip operating unit performs at least a rotation operation along an axial direction or a swing operation that crosses the axial direction. The console changes a driving speed of the motors and includes a speed setting unit that changes an operating speed of the rotation operation or the swing operation of the tip operating unit.
