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.

The present disclosure relates to a display system including a capsule image view, a 3D mini-map, and a 3D panoramic view, and a method of generating a 3D panoramic view. Specifically, according to the present disclosure, it is possible to infer the shape of an organ using a 3D mini-map and to simultaneously identify whether or not the capsule endoscope captures the images, and information on the position and posture of the capsule endoscope at primary captured points by visualizing the actual movement path of the capsule endoscope, thereby improving the accuracy of examination, and since multiple 2D images captured by a single capsule endoscope are able to be viewed as a single 3D panoramic image without changing the structure of the capsule endoscope, it is economical and the viewing angle of the image is able to be increased, thereby reducing the examination time and fatigue of the examiner.
