The present invention relates to a medical manipulator equipped with a fail-safe mechanism capable of protecting a manipulator in an emergency. A medical manipulator includes a supporting section a driving section supported by the supporting section and including a vibrating body in which vibration waves are excited by application of an alternating voltage, a movable body that moves relative to the vibrating body by receiving the vibration waves, and a pressurization unit configured to exert pressure between the vibrating body and the movable body a manipulator section supported by the driving section an emergency detecting unit configured to detect an emergency and an interruption unit configured to interrupt transmission of torque between the manipulator section and the supporting section on the basis of an emergency detection signal transmitted from the emergency detecting unit.
