MICRO-ROBOT AND A SYSTEM FOR INTRAVASCULAR THERAPY

摘要

The present invention relates to a micro-robot for intravascular therapy capable of wirelessly removing foreign materials from blood vessels using alternating magnetic fields and a system thereof. The micro-robot of the present invention includes a housing (110) which has a cutting tool (111) on the front of one side and has a guide hollow (112) therein, and a permanent magnet (120) which is located in the guide hollow (112) and can move forward and backward. The micro-robot can be driven by alternating magnetic fields generated from an external a gradient magnetic coil unit, can be easily manufactured due to a simplified structure, and allows effective intravascular therapy.
