A medical manipulator (10A) includes a surgical tool (12) that has an end effector (11) at a distal end and a drive unit (14) that is detachable from a handle (16) of the surgical tool (12). In a state where the drive unit (14) is mounted on the handle (16), when a manipulation lever (52) is manipulated, a driving force of a motor (50) is transmitted to the handle (16), and the end effector (11) is operated. Even in a state where the drive unit (14) is detached from the handle (16), the surgical tool (12) can be independently used by a manual manipulation.
