概要

It has been a problem in some hospitals that operations using surgical microscopes for brains and eyes bacome more difficult due to microvibrations of the microscopes caused by human wolks and building equipment such as air conditioning machines. For a practical solution to it, a microvibration control system was developed, in which an active dynamic vibration absorber using a small mass of 0.34 kg driven by an electromagnet and an accelerometer were collocated for vibration control in each direction. The system was attached on the point of the arm of the microscope. A direct velocity feedback control law was developed for the microscopes having various dynamic characteristics corresponding to their attiudes. Furthermore an active-passive switching law was developed to manage large vibrations of the microscopes due to doctors' handling of them. Tests showed that the microvibration control system was effective and reliable enough for real application.
