ABSTRACT:
A balanced suspension system for a surgical investigative instrument, such as a surgical microscope, is configured so that the amount of force to move the microscope in any direction is approximately equal, and when the suspension system is unlocked to move the microscope no residual forces will spontaneously move the microscope. The suspension system comprises a generally vertical support structure, a levered assembly extending out therefrom, a gimbal mount assembly connected adjacent one end of the levered assembly. The gimbal mount assembly includes a bracket arm having a first joint member at one end thereof and an instrument bracket, for holding the microscope, connected to a second end thereof by a second joint member. The instrument bracket includes a third joint member, so that the center of mass of the microscope lies within the three planes of motion permitted by the first, second and third joint members.
