Stativvorrichtung für medizinisches, optisches Instrument

摘要

The invention provides a stand apparatus for a medical optical instrument, in which a rear-side parallel link mechanism and a counterweight are arranged below those of a conventional arrangement. The rear-side parallel link mechanism (11) having the counterweight (W) is arranged below that of the conventional arrangement, and operation of a front-side parallel link mechanism (10) is transmitted to the rear-side parallel link mechanism (11) through a transmission mechanism (13). Accordingly, a weight balance of the medical optical instrument (18) is surely tried by the counterweight (W) similarly to the conventional arrangement. Further, an upper rear space (SP), which has conventionally been occupied by the rear-side parallel link mechanism (11), can freely be used by an operator and an assistant and, therefore, this becomes very convenient. Furthermore, a position of the center of gravity of the entire stand apparatus is lowered considerably, and stability of the stand apparatus increases.
