Abstract: The present invention relates, in general, to a microrobot system for intravascular therapy and, more particularly, to a microrobot system for intravascular therapy, which removes thrombus, clots and occlusions that are clogging blood vessels using the fast rotary power of a spherical microrobot having protrusions, thus treating clogged blood vessels. The microrobot system for intravascular therapy according to the present invention includes a spherical microrobot unit (100?) including a magnet having an arbitrary magnetization direction and having protrusions formed on a surface thereof. An electromagnetic field generation unit (200) sets an alignment direction and a locomotion direction of the microrobot unit to arbitrary directions in the 3D space, generates magnetic fields, and then drives the microrobot unit so that the microrobot unit is rotated by itself or is propelled in the locomotion direction. An imaging unit (300) captures an X-ray image and then tracking a location of the microrobot unit.

Abstract: Disclosed is a microrobot for the therapy of brain/spinal cord diseases. It comprises a microrobot comprising a driving unit having a magnet therein, and a therapeutic means or drug delivery means for treating a disease lesion; a microrobot driving module for performing and controlling various motions of the microrobot by generating an electromagnetic force through an electromagnetic coil system; an imaging module for imaging a thecal sac filled with cerebrospinal fluid, a ventricle, and the microrobot; a diagnosis module for diagnosing the brain/spinal cord disease, based on a pre-operative image produced by the imaging module; and a navigation module for planning a moving path for the microrobot, based on the pre-operative image produced by the imaging module and for monitoring the microrobot through an intraoperative image produced by the imaging module.
