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.

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). [Reference numerals] (AA) Start; (BB) Yes; (CC) No; (DD) End; (S10) Generating image information from an laparoscope image; (S20) Extracting an interest region from the image information; (S30) Determining operation situation from change of the interest region; (S40) Performing predetermined operation corresponding to the operation situation; (S50) Finish?
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 surgical instrument is provided to selectively use auxiliary tools integrated in the surgical instrument by exposing the auxiliary tools the tip part of a shaft when necessary. CONSTITUTION: A shaft(10) is extended in a longitudinal direction. An effecter(12) is inserted into a portion to be operated an implements necessary operations. Auxiliary tools(14), including a first tube for suction, are accepted in the shaft. A driving unit(20) operates the tip part of the auxiliary tools to be exposed through the tip part of the shaft.
