ARTICULATOR Russian patent published in 2018 - IPC A61C11/00 B25J11/00 

FIELD: robotics.

SUBSTANCE: invention relates to robotics, or more precisely to medical robots, used in orthopedic dentistry as automatic articulators – imitators of the movement of the lower jaw, with the help of which the dentition is adjusted for prosthetics. Articulator contains actuators and a base for the lower dental rows, connected through hinges to the actuator rods. Each drive is provided with four magnetic systems comprising an excitation source having a core, surrounded by excitation coils, and two magnetic circuits. In this case, two three-stage drives are used in parallel on a common base, each of which contains a coil mounted in springs that are radially fixed relative to the center of the coil, located in the field of the uniformly spaced apart magnetic systems.

EFFECT: invention is aimed at simplification of the design.
