  • Patent number: 9255855
    Abstract: A first angle acquiring unit acquires a rotational angle of a characteristic portion in a predetermined region on an inlet side of an insertion member of a linear body extending through the insertion member. From an image of the linear body inserted into a body of a subject, a second angle acquiring unit acquires a direction of a curved portion of the linear body inserted into the body of the subject and then acquires a rotational angle of a distal end of the linear body. A torque calculation unit calculates a torque based on a difference between the rotational angle in the predetermined region acquired by the first angle acquiring unit and the rotational angle of the distal end of the linear body acquired by the second angle acquiring unit.

  • Publication number: 20140350726
    Abstract: A master device is provided to a master slave apparatus in which a hand mechanism opens/closes to grip a target object and a slave mechanism performs a task on a target article. The master device includes a hand manipulation mechanism for manipulating the hand mechanism. A person remotely manipulates the slave mechanism by a master mechanism and the hand manipulation mechanism manipulates to cause the hand mechanism to perform the task. In the hand manipulation mechanism, a hand manipulation portion having a pair of open/close manipulation portions manipulated by the person moves forward/backward on a slider, the pair of open/close manipulation portions is opened/closed to change the angle therebetween so that the hand mechanism is opened/closed. A master hand control device transmits, to the slave mechanism, motion information used for manipulating the hand mechanism based on a position of the hand manipulation portion relative to the slider or the angle.
