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.

An electromagnetic actuating device. A coil unit generates magnetic field toward a medical device inserted into a human body. An actuator drives the coil unit to move back and forth, thereby adjusting the rate of a change in magnetic force or magnetic field applied to the medical device. The coil unit moves linearly back and forth depending on the body shape of a subject and the body part to be diagnosed, such that actuation force is efficiently supplied to the medical device.
