  • Medical manipulator device and actuator suitable therefor
    Patent number: 8465414
    Abstract: A clean and inexpensive medical manipulator device can be provided in which a risk of failure caused by current leakage or disconnection is eliminated and reliability is higher than in a manipulator device using an electrically driven actuator or electric motor. The medical manipulator device includes a stage section 3 that can hold a medical instrument 2; a plurality of actuators 4 each linked at one end to the stage section 3; and a base section 5 linked to the other end of each of the plurality of actuators 4 and serving as a base for the plurality of actuators 4, wherein each of the actuators 4 causes the medical instrument 2 and the stage section 3 to displace with respect to the base section 5 by extending or contracting in the longitudinal direction of the actuator 4 in response to a pressure of a liquid 6.
