Abstract: The present disclosure provides a magnetic actuation system including a curved magnetic core forming a magnetic field or magnetic force through current supplied thereto to control a therapeutic magnetic actuation robot. The magnetic actuation system includes an electromagnet array including a plurality of electromagnets aligned in an arrangement space, wherein each of the plurality of electromagnets includes an electromagnet body linearly extending while including a magnetic core and a coil wound around the magnetic core, and a magnetic core front end portion extending from the magnetic core to protrude from the electromagnet body, and the magnetic core front end portions of the plurality of electromagnets are oriented to be bent toward a target position.

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.
