  • Patent number: 9136051
    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.

  • Patent number: 9089271
    Abstract: A system for controlling actuation of a capsule endoscope includes a receiving unit receiving an image transmitted from the capsule endoscope; a coil unit generating a magnetic field for actuating the capsule endoscope by using current applied thereto; a power supply unit supplying power to the coil unit; and an actuation controller control the current applied to the coil unit and a coil rotational motor for adjusting of a posture and the location of the capsule endoscope based on the identified lesion or location of the capsule endoscope, wherein the coil unit includes a pair of Helmholtz coils and a pair of Maxwell coils that are fixedly disposed on a main axis; and a pair of uniform saddle coils and a pair of gradient saddle coils that are located inside the pair of the Helmholtz coils and the pair of the Maxwell coils to rotate around the main axis.

  • Patent number: 8821386
    Abstract: A micro robot system movable on three dimensional space includes a micro robot unit including a magnet module having a certain magnetization direction and configured to rotate and proceed along a wall by a processional rotating magnetic field, and an electromagnetic field generation unit configured to set an alignment direction of the micro robot unit to have a certain angle with respect to the magnetization direction and configured to generate a magnetic field in the alignment direction to drive the micro robot unit.
