Definitions
- a surgical microscope which is a heavy object, and its attached equipment are held by a holding link mechanism using a parallel link at the time of microsurgery (MI CROSURGERY), and their weights are counterweighted.
- the present invention relates to a stand capable of stopping the surgical microscope or the like at a desired spatial position by balancing. Techniques-Brain surgery and heart surgery are performed while observing the affected area with a surgical microscope, and are very detailed and use nerves. In many cases, the operation time is long. Such a prolonged operation time is undesirable for both the patient and the doctor, as it increases physical and mental fatigue.
- Medical optical devices such as surgical microscopes play a very important role in such advanced surgery, and the ease of use of medical optical devices directly leads to a reduction in operation time.
- Conventional stand devices for medical optical equipment as shown in FIGS. 10 and 11 (Japanese Patent Application Laid-Open No.
- 1 is a stand base

Performed by assistants who are not involved in the operation due to hygiene requirements. The person moves the stand device to the specified position and locks it, and then adjusts the level so that the entire stand device is completely horizontal. Because the floor F of the operating room is not strictly horizontal in the strict sense, the rotation axis a is inclined without leveling, and when the electromagnetic clutch C becomes free, the This is because there is a risk that the structure of two or more poles may be largely rotated about the rotation axis. As described above, each time the conventional stand device changes its position, it must be leveled at that position, and handling is very troublesome.
