Abstract:
The present invention relates to a system for bone motion monitoring and path correction using a three-dimensional optical measuring unit, and more particularly, to a system that monitors the motion of a bone during surgery, extracts a change in coordinates according to the motion that has occurred, and corrects a path of a surgical robot using the change in coordinates. In order to achieve the above aim, the system of the present invention includes: an optical target unit attached to a bone for detecting motion; an optical measuring unit for measuring the motion of the optical target unit and extracting the degree of change when a motion occurs; a motion-detecting unit for detecting whether or not a bone moves as the degree of change extracted by the optical measuring unit is inputted, and correcting the path of a surgical robot; and said surgical robot for performing a cutting operation along the path corrected by the motion-detecting unit, or along a predetermined path.

PURPOSE: A method for modifying the surface of polymer-based substrate for the deposition of a gold thin film is provided to improve interface adhesion between a gold thin film formed on the surface of the polymer-based substrate and a substrate. CONSTITUTION: A method for modifying the surface of polymer-based substrate for the deposition of a gold thin film comprises the steps of: introducing a -COOH functional group to the surface of a polymer-based substrate for depositing the gold thin film; activating the introduced -COOH functional group; and introducing an -SH functional group to the surface of the polymer-based substrate using the activated -COOH functional group.
Abstract:
PURPOSE: A system and method for controlling a micro robot using a dual source X-ray CT device is provided to precisely control the location of the micro robot by using the coordinate and vector information of the micro robot as a feedback signal. CONSTITUTION: A CT scanning unit(110) uses a dual source X-ray included in a body(100). A coil unit(120) generates a driving signal for driving a micro robot. A driving unit(130) rotates the coil unit and the CT scanning unit in the body. A control unit controls the location of the micro robot by controlling the coil unit or driving unit and includes an image information processing module, a matching module, and a control module.
Abstract:
PURPOSE: A bone motion monitoring and path regenerating system using a three-dimensional optical tracker is provided to improve the reliability and quality of a robot surgery by automatically correcting the operating path of a robot. CONSTITUTION: An optical target unit(100) is attached to bone and detects a movement. An optical measuring unit(200) measures the movement of the optical target unit and extracts the amount of change. A movement sensing unit(300) senses the movement of the bone according to the inputted change amount extracted by the optical measuring unit and corrects the path of a surgical robot(400). The surgical robot implements cutting along a predetermined path or the path corrected by the movement sensing unit.
