  • Patent number: 10660655
    Abstract: The present invention relates to a medical drill device. The medical drill device includes a boring drill including a motor and a drill part; an instrument body coupled to the boring drill; and a plurality of supporting rods coupled to the instrument body so as to support the boring drill to a work area. Each of the supporting rods includes: a straight portion inserted into the corresponding supporting rod insertable part in such a manner that the supporting rod is linearly moved with the instrument body; and a bent portion bent at a predetermined angle from the straight portion. As such, by using the supporting rods having a bent structure to support a boring drill to a work area and simultaneously limiting a boring depth of the boring drill, it is possible to shorten boring time and ensure safety of the boring operation.

  • Patent number: 9105092
    Abstract: In order for registration of images for surgery, first, a three-dimensional reference image of a surgical area of a patient before surgery is acquired. Then, a grating-pattern light is provided towards the surgical area to acquire a first measurement image. Thereafter, a preliminary registration is performed between the acquired first measurement image and a pre-acquired three-dimensional reference image. Then, a grating-pattern light is provided towards the surgical area after cutting out the surgical area to acquire a second measurement image. Thereafter, a fine registration is performed between the acquired second measurement image and the pre-acquired three-dimensional reference image based on the preliminary registration result. Thus, an accurate registration result may be acquired at low cost in a short period of time.

  • Patent number: 8442721
    Abstract: A steering controller for a movable robot is provided. The steering controller drives a plurality of motors, each of which is connected to a wheel. The wheels are spaced apart from each other in the circumferential direction with respect to an axis of a body of the movable robot. The steering controller comprises an input unit, an output unit and a conversion unit. The input unit receives steering signals including velocities of the movable robot according to the moving directions. The output unit outputs driving signals including rotational velocities of the motors. The conversion unit converts the steering signals to the driving signals. The use of the steering controller enables an operator to intuitionally steer the movable robot, making the movable robot convenient to use.
