  • Patent number: 8009140
    Abstract: In a master-slave manipulator system, an intuitive operation can be achieved by a simple structure in which a layout of a monitor and an operation input device is not limited. A master-slave manipulator system is provided with a manipulator, a camera, a monitor, an operation input device, a manipulator controller and a master controller. The master controller is provided with an operation an information acquisition portion for operation command acquiring an operation reference data on the basis of the command by the operation input device, an acquirement information division portion dividing the operation reference data into a position movement reference data and an orientation reference data, and a moving direction compensation controller compensating the position movement reference data on the basis of the orientation reference data so as to output a position moving command compensation information.

  • Patent number: 7955321
    Abstract: A top end portion of a medical manipulator has a surgical device accessible to a diseased area of a patient. In the manipulator, a pair of rolling members opposing to each other is provided. One of the pair of the rolling members is rolled by a flexible wire relative to the other rolling members. A plate maintains a distance between rotation centers of the pair of the rolling members constant. A pair of gears are held coaxially with the pair of the rolling members respectively, and engaged with each other. A link rotates the gear on an opposite side to a surgical device.

  • Publication number: 20080319474
    Abstract: Provided is a surgical tools having multiple functions exhibited by end effector parts, which is small-sized and inexpensive, and which can eliminate the necessity of replacement of surgical tools. The surgical tools incorporating: a tip end portion having a plurality of end effector parts, and a tool sleeve through which a transmission mechanism of driving force for applying driving force to the tip end portion is led. The plurality of end effector parts comprise a pair of a first end effector part and a second end effector part so as to have a first tool function, and a third end effector part mated with one or both of the first end effector part and the second end effector part so as to have a second tool function.

  • Publication number: 20080310945
    Abstract: The invention provides a manipulator which can carry out a treatment having a large moving amount in a manipulator leading end while being compact. The manipulator is provided with a manipulator shaft portion, a first rod supported so as to be capable of linearly moving with respect to the manipulator shaft portion and driven by a driving force of a driving source, a first gear rotatably supported to the first rod, a first rack supported to the manipulator shaft portion, a second rack supported so as to be capable of linearly moving in the same direction as the first rod with respect to the manipulator shaft portion, and a end-effecter driven by the driving force of the second rack. The first rack and the second rack are arranged in such a manner that respective cogged surfaces come face to face. The first gear is pinched between the first rack and the second rack, and is arranged in an engaged state.

  • Patent number: 7101363
    Abstract: A manipulator for medical use having a reduced size and improved controllability. The manipulator includes a surgical tool portion, a grip portion provided on the surgical tool portion, and a driver portion for driving the grip portion provided on the surgical tool portion. A connection portion of the surgical tool is provided between the surgical tool portion and the driver portion. The surgical tool can be separated from, and connected to, the driver portion. The surgical tool portion has two rotating members disposed in opposing relation to each other. A driving arrangement is provided for driving one of the rotating members and causing it to revolute the other rotating member, but not rotate by itself. An arrangement is also provided for keeping a distance between rotation centers of the two rotating members constant.
