Abstract: The present invention relates to a micro robot driving apparatus which can increase the intensity of magnetic field generation in a driving area of a micro robot by attaching a magnetic shield unit to an electromagnetic drive coil unit for driving the micro robot, or locally focus a magnetic field through the combination of two electromagnets, and a system using the same. According to the present invention, there is an effect that driving the micro robot injected into the body may be controlled by increasing a magnetic field generation intensity in the region of interest or focusing the magnetic field.

Abstract: The present invention relates to a medical robot system capable of effectively removing a calcified thrombus in a blood vessel. The present invention proposes a new guide-wired helical microrobot for mechanical thrombectomy applied to a calcified thrombus. Also, the present invention proposes an electromagnetic navigation system (ENS) which uses a high frequency operation that is based on a resonant effect in order to enhance the boring force of a microrobot. The microrobot system of the present invention can precisely tunnel through a blood vessel blockage site by means of the electromagnetic navigation system without damaging blood vessel walls. The microrobot system of the present invention has a wide range of applications including not only for thrombosis, but also thromboangiitis obliterans caused by vasoocclusion, cerebral infarction, strokes, angina or myocardial infarction, peripheral artery occlusive disease, or atherosclerosis, etc.
