  • MAGNETIC ACTUATION DEVICE USING PERMANENT MAGNETS AND SYSTEM USING THE SAME
    Publication number: 20240145143
    Abstract: Provided are a magnetic actuation device using a permanent magnet which may generate a magnetic field for a long time with lower power and lower heat by using the permanent magnet, and a system using the same. The magnetic actuation device may utilize the plurality of permanent magnets for controlling an alignment direction with two degrees of freedom to thus exclude an actuation element limiting space utilization, such as a robot arm, thus allowing an operator using a medical device to perform a safe procedure on a patient.
