    摘要： To provide a surgical microscope comprising a microscope collimator for enabling the operator to easily recognize the swivel center of the microscope body regardless of what position the microscope body moves for easy setting of the swivel center point of the microscope body, a surgical microscope pivotally supporting a microscope body having, an observation optical system with one point on an observation optical axis of the microscope body as the swivel center. The surgical microscope comprises index projectors as swivel center visible indicators being capable of recognizing the swivel center. This configuration enables the operator to easily recognize the swivel center of the microscope body for easy setting of the swivel center point of the microscope body. Also, to provide a surgical microscope which does not disturb an operator who handles the microscope or performs an operation and also enables the operator to easily observe at every angle from every direction for improving operability, the surgical microscope is capable of changing an observation angle and an observation direction with a gaze point P on an observation optical axis a of a microscope body having an observation optical system as a rotation center. A base unit that can be moved in X, Y, and Z directions is disposed at a position relative to the microscope body and a swivel base rotatable with the gaze point P as a rotation center is installed above the base unit.

    摘要： An operating microscope includes a base and a support coupled to the base. An arm has a proximal end portion rotatably and/or vertically movably coupled to the support, and a distal end portion. At least the distal end portion is formed of a non-magnetic material. A microscope portion is coupled to the distal end portion of the arm and includes a stereoscopic optical system for forming an image of an observed part. The microscope portion is formed of a non-magnetic material. The operating microscope also includes a power system for operating the microscope portion or a part thereof, and an operation instructing portion for instructing the power system to operate. The power system includes a power generating portion for generating a pressure change or a positional change; a power output portion, formed of a non-magnetic material, for converting the pressure change or the positional change of the power generating portion into a power for operating the microscope portion and a part thereof; and a power transmitting mechanism for transmitting the pressure change and the positional change from the power generating portion to the power output portion. The power transmitting mechanism is formed of a non-magnetic material at least near the power output portion.

    摘要： A surgical microscope unit which is compact and operated lightly at high stability has first and second parallelogrammic linkages, interlocking mechanisms for interlocking the first and second parallelogrammic linkages, a counterweight connected to an arm of the second parallelogrammic linkage, flexible movement transmitting members for transmitting tilting movements of the microscope body around pivot axes directly to a tilting rod as tilting movements around pivot axes at the same ratio, and a movement controlling mechanism for limiting a moving locus of the tilting rod to a corresponding location at which the microscope unit is set. The pivot axes are arranged so that a triangle formed by connecting the pivot axes is similar to a triangle formed by connecting the pivot axes in a plane parallel with a plane including a vertical axis. Auxiliary counterweights are provided on members interlocking with either the first interlocking mechanism or the second interlocking mechanism. When the microscope body is moved, the balancing weight does not project from the microscope body.

    摘要： A distal arm that holds a rigid endoscope includes a multi-joint articulated arm including first to fourth distal arm portions sequentially connected from a base portion side, and these first to fourth distal arm portions are configured so as to move on a vertical plane with horizontal rotational shafts as supports. In addition, behaviors of the respective distal arm portions are linked by a linking mechanism so that the first distal arm portion and the third distal arm portion behave in parallel to each other, and the second distal arm portion and the fourth distal arm portion behave in parallel to each other.

    摘要： An apparatus for supporting a medical instrument includes an arm, which has a support portion to support a medical instrument at one end, and an intermediate portion of which is supported by a base portion via a support column. The arm moves the support portion horizontally and vertically. The apparatus also includes a rotary connecting member, which is provided at a second end of the arm and moves to a position corresponding to a position to which the support portion has been moved. The apparatus further includes a counterweight, which is connected to the support column to be immovable in the horizontal directions and movable in the vertical directions, and generates vertically downward force. The rotary connecting member is connected to the counterweight so as to be movable in the horizontal directions relative to the counterweight and movable in the vertical directions together with the counterweight.
