Description
Technical Field
The utility model relates to the field of medical equipment, a surgical microscope is related to, especially relate to a surgical microscope hang arm.
Background
At present, the suspension arm and each rotary joint of the domestic operation microscope are locked by a mechanical locking mode. Before each joint is rotated, the locking knobs of the rotary joints are loosened by hands respectively, and after the rotary joints are rotated to required positions, the rotary knobs are screwed tightly, so that the positions are not moved during operation, and the operation is complicated.
The operation microscope has the working requirements that the joints of the frame are kept locked at ordinary times and are loosened when the joints need to rotate, so that the electromagnetic locking device can be selected to realize the working requirements of power-off braking and power-on loosening. When the existing power-off brake product is electrified, the friction plate and the fixed disc generally rotate at a high relative speed (up to 3000r/min), the electrifying time is long, and braking is realized through spring friction after power-off. In the braking process, relative dynamic friction motion exists between the friction plate and the fixed disc, the heating value is large, and the requirement on the friction plate material is high. Therefore, the design parameters of the electromagnetic locking device are smaller in consideration of factors such as heating. The braking torque of the existing electromagnetic brake in the required volume is therefore too low and structurally unsatisfactory.
