ABSTRACT:
In a stand apparatus for a medical optical instrument, a first link mechanism including a first pantograph arrangement has a proximal end which is mounted on a body having a horizontal groove. The body is rotatable about a vertical axis. The first pantograph arrangement has an intermediate section which is slidably engaged within the horizontal groove. The first pantograph arrangement reciprocating linearly along a horizontal direction has a forward end on which a horizontal moving element having a vertical groove is mounted. A second link mechanism including a second pantograph arrangement has a proximal end which is mounted on the horizontal moving element. The second pantograph arrangement has an intermediate section which is slidably engaged within the vertical groove in the horizontal moving element. The medical optical instrument is supported at a forward end of the second pantograph arrangement which reciprocates linearly along a vertical direction. A counter weight for canceling a weight of the medical optical instrument is provided within the first link mechanism.
