  • Patent number: 11992278
    Abstract: Provided is a robot for vascular intervention. The robot for vascular intervention comprises: a catheter driving unit for rotating and translating a catheter extending in a longitudinal direction while having the longitudinal direction as an axis; a guide wire driving unit provided at a side of the catheter driving unit, drawing a guide wire into the catheter by translating the guide wire, and rotating the guide wire coaxially with the catheter; a micro-catheter driving unit provided at a rear of the catheter driving unit and translating the micro-catheter in a path coaxial with the catheter that is different from draw-in and draw-out paths of the guide wire when the guide wire is drawn out from an inside of the catheter; and a micro-guide wire driving unit provided at a rear of the micro-catheter driving unit, and drawing a micro-guide wire into the micro-catheter by translating the micro-guide wire, and rotating the micro-guide wire coaxially with the micro-catheter.

  • Patent number: 8874241
    Abstract: A master-slave system using a 4-degree of freedom (DOF) parallel mechanism includes: a master device having a 4-DOF parallel mechanism which generates 1-DOF translation and 3-DOF rotation by the manipulation of a user; a slave device having a 4-DOF parallel mechanism which generates 1-DOF translation and 3-DOF rotation according to the movement of the master device; and a controller for receiving a behavior signal generated by the master device and outputting a driving signal to the slave device so that the slave device moves according to the movement of the master device. The master-slave system may be utilized as a remote needling robot with excellent manipulation and precision.
