  • Patent number: 8121666
    Abstract: An image observation apparatus comprising an image display unit for displaying an observation image and a supporting mechanism for supporting the image display unit movably and adjustably in the directions of three, substantially perpendicular axes. Since the supporting mechanism of this image observation apparatus can move and adjust the image display unit in three orthogonal axial directions, an operator need not select a plurality of articulates for operating them when he/she wants to move the image display unit to a desired axial direction. Further, one of the three axes can be a rotational axis for turnably supporting the image display unit around the operator. According to this configuration, the image display unit can be independently moved and adjusted in three axial directions, while the observation angle of the observer with respect to the display face of the image display unit is kept constant.

  • Patent number: 7904206
    Abstract: An apparatus for holding a medical device has an arm unit equipped with, for example, a polyarticular arm, which holds the medical device such as endoscope movably in the space. Additionally to a determination unit and a controller, the holding apparatus has an operation unit equipped with a plurality of operation members with which an operator's operation causes the arm unit to be moved spatially. The determination unit determines whether or not operator's operations at the plurality of operation members corresponds to an improper state deviating from a properly operated state in which at least two predetermined operation members have been operated within a predetermined period of time which is set to measure simultaneity for operations. If it is determined that the operation is in the improper state, the controller prohibits the arm unit from moving. As long as the operation is proper, the arm unit can be moved.
