Abstract

An operating microscope includes a base and a support coupled to the base. An arm has a proximal end portion rotatably and/or vertically movably coupled to the support, and a distal end portion. At least the distal end portion is formed of a non-magnetic material. A microscope portion is coupled to the distal end portion of the arm and includes a stereoscopic optical system for forming an image of an observed part. The microscope portion is formed of a non-magnetic material. The operating microscope also includes a power system for operating the microscope portion or a part thereof, and an operation instructing portion for instructing the power system to operate. The power system includes a power generating portion for generating a pressure change or a positional change; a power output portion, formed of a non-magnetic material, for converting the pressure change or the positional change of the power generating portion into a power for operating the microscope portion and a part thereof; and a power transmitting mechanism for transmitting the pressure change and the positional change from the power generating portion to the power output portion. The power transmitting mechanism is …
