Magnetic lock suspension and remote control microdriver for operating microscope

Frequent adjustment of the angle and the focus of the operating microscope is the most important but troublesome manoeuvre during microneurosurgery. We have designed a new suspension and control system for the operating microscope. There is a magnetic lock system of all joints and axes for gross movement of the microscope and the other facility is a remote control microdriving system for fine adjustment of the focus either with the hand or a pedal control box. This system could effectively save operating time as well as surgeon's physical exertion.
