ABSTRACT:
Disclosed is a biaxial balance adjusting structure for a medical stand apparatus, containing a retaining link mechanism 4, utilizing a parallel link 2, supported on the pivot S of a frame 1; a medical optical device W.sub.1 and/or auxiliary devices W.sub.2, W.sub.3, disposed to one end portion of the retaining link mechanism and a counterweight disposed on the other end portion thereof relative to the pivot S; characterized in that the counterweight consists of a first counterweight W.sub.4 which can be moved in the horizontal direction and a second counterweight W.sub.5 which can be moved in the vertical direction, and that the balance adjusting structure employs a system for moving the first and second counterweights W.sub.4, W.sub.5 interlocking with each other to be closer to or farther from the pivot S in the respective directions. Thus, balance adjustment in accordance with the weight change on the operating microscope side can be facilitated.
