Abstract
A stand mechanism for medical optical equipment wherein the focus of the optical equipment remains upon an extension of a straight line connecting the two base ends of a parallel linkage, and the focus of the medical optical equipment remains fixed at a fixed position when the parallel linkage is transformed. Accordingly, the medical optical equipment does not need to be focused even whe the parallel linkage is moved and therefore, the operating time can be remarkably reduced. Furthermore, since the observation angle can be changed with the focus upon the fixed point, the diseased region can be observed from an optimum observation angle, and hence the operation can be carried out more exactly and more rapidly.
