Abstract:
PURPOSE: A master arm structure of a robot for an operation and a method for controlling a master robot are provided to control the operation of a master arm by operating a break installed on each joint after detecting an operation state of the master arm so that a user feels haptic feedback when manipulating the master arm. CONSTITUTION: A master arm structure of a robot for an operation comprises a handle(3), an arm part(10), a brake(16), a detecting part(20), and a control unit(30). The handle is operated by a user. The arm unit connects a master robot and the handle and is formed into a structure that a plurality of arm members(12) is connected by a joint(14). The arm members rotate around the joint so that the handle is positioned. The brake is installed in the joint and controls the rotation of the arm members The sensing unit obtains information with respect to one or more of a state that the handle is operated and a state that the arm part is operated. The control unit controls the operation of the brake by using the information obtained by the sensing unit.
Abstract:
PURPOSE: A control method for a surgical robot system capable of determining and managing a surgical situation, a recording medium thereof, and the surgical robot system are provided to automatically perform a predetermined operation for managing a surgical situation by determining a current surgical situation from laparoscope images in real time. CONSTITUTION: Image information including one or more of RGB values or HSV values, which represent pixel information of laparoscope images, is generated from the laparoscope images(S10). An interest region in the laparoscope images is extracted from the generated image information(S20). A current operation situation is determined from changes according to time flow in the extracted interest region(S30). A predetermined operation for dealing with the determined operational situation is performed(S40).

Abstract:
PURPOSE: A surgical robot system and a control method thereof are provided to prevent structure change by additionally adding an exclusive driving part which is in charge of operational freedom of an instrument. CONSTITUTION: A first driving part(20) combines a robot with an instrument. The first driving part includes the n(N is natural number) number of basic drivers so that the instrument operates at an n freedom degree. A second driver part(30) is combined with the instrument and includes the m number of extra drivers so that the instrument operates at an n+m(n+m is natural number) freedom degree. A sensing part(40) sense drive information of the second driver part and outputs a sensing signal.
Abstract:
PURPOSE: A wheel connection structure and connection structure of surgical instrument are provided to improve the accuracy of sensing and to reduce volume and cost. CONSTITUTION: A wheel connection structure comprises drive wheels(30,50), a driven wheel, and a Y-matching sensor(35). The drive wheel receives the driving force from a surgical robot arm. The driven wheel is matched with the drive wheel. The Y-matching sensor is combined in the drive wheel or the driven wheel. The Y-matching sensor senses the electric change generating in the Y-matching of the driven wheel and drive wheel and senses connection state.
Abstract:
PURPOSE: An operation robot system and a method for controlling the same are provided to implement a smooth operation by simultaneously displaying real operation tools and virtual operation tools using augmented reality. CONSTITUTION: An image input part(310) receives images inputted through a camera which is installed in the laparoscope of a slave robot(2). A screen display part(320) visually outputs picture images corresponding to images of the image input part. An arm manipulation part(330) manipulates the position and the function of the robot arm of the slave robot. A manipulation signal generating part(340) generates a manipulation signal and transfers the generated manipulation signal to the slave robot. A augmented reality implementing part(350) outputs the image of a operation part and virtual operation tools.
Abstract:
PURPOSE: A robot for a surgical operation is provided to have a simplified structure by integrating an instrument into a robot arm. CONSTITUTION: A robot for a surgical operation comprises a manipulation part(10), a robot arm(20), and an effector(30). A single port is formed in the surgical operation region of a patient. The manipulation part is used to execute a manipulation for a surgical operation according to the manipulation of a user. The robot arm is rotated according to the manipulation of the user. The effector is combined with the end part of the robot arm. The effector executes an operation which is required for the operation according to the manipulation of the user. The robot arm and the effector are inserted into the body of the patient through the single port.
