  • Publication number: 20210220068
    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.
