  • Patent number: 12128585
    Abstract: The present invention relates to a manufacturing device for manufacturing a large amount of micro-scaffolds for a long period of time such that stable and uniform particles can be fabricated. The manufacturing device comprises: a first solution storage portion for storing a polymer support structure solution; a second solution storage portion for storing an emulsifier solution; a gas storage portion connected to each of the first solution storage portion and the second solution storage portion; a pressure control portion for controlling the pressure of the transporting gas flowing into the first solution storage portion and the second solution storage portion from the pressurization portion, respectively; a scaffold injector portion for receiving the polymer support structure solution and the emulsifier solution provided by the transporting gas, respectively; and a scaffold generating portion for receiving the scaffold dispersion discharged through the scaffold injection portion.

  • Patent number: 12070290
    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.

  • Patent number: 10004566
    Abstract: 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.
