Treatment efficiency is improved regardless of the skill of an operator. Provided is a medical manipulator system (1) including: a manipulator (3) including a surgical section to be applied to a patient and a driver that drives the surgical section； an operation input unit (2) that is operated by an operator and that is used for inputting an operation command for the manipulator (3)； a controller (4) that controls the driver based on the input operation command； an identification-information input unit (5) that is used for inputting identification information of the operator； and a history-information storage unit (6) that stores history information of an operation performed on the operation input unit (2) by the operator in association with the identification information of the operator input via the identification-information input unit (5). The controller (4) performs control so as to increase a maximum operating speed of the manipulator (3) and/or expand an operating range of the manipulator (3) as a skill of the operator becomes higher. The skill of the operator is estimated based on the history information stored in the history-information storage unit (6) in association with the identification information input via the identification-information input unit (5).
