US 2010/0137680 A1 · MEDICAL MANIPULATOR DEVICE AND ACTUATOR SUITABLE THEREFOR

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.

Dependent claims

A medical manipulator device that displaceably holds a medical instrument, comprising:

a stage section that can hold the medical instrument;
a plurality of actuators each linked at one end to the stage section;
a base section linked to the other end of each of the plurality of actuators;
and
an introducing chamber which is provided in each of the actuators and into which a liquid can be introduced, wherein
each of the actuators causes the medical instrument and the stage section to displace with respect to the base section by extending or contracting in the longitudinal direction of the actuator in response to a pressure of the liquid inside the introducing chamber.

3 more elements

An actuator for use in a medical manipulator device that holds a medical instrument and comprises a base section, and a stage section that can hold the medical instrument,

the actuator comprising:
a first linking section that is provided at one end of the actuator and can be linked to the base section;
a second linking section that is provided at the other end of the actuator and can be linked to the stage section;
and
an introducing chamber into which a liquid can be introduced, wherein
the actuator extends or contracts in response to a pressure of the liquid introduced into the introducing chamber, so that the first linking section and the second linking section approach or separate from each other.
