1. A device for providing information about joint replacement robotic surgery, the device comprising:
a memory unit configured to store surgery plan information set before surgery including a cutting path of a surgical target bone;
a target acquisition unit configured to acquire positions of a plurality of cutting target points forming the cutting path based on the surgery plan information, wherein the target acquisition unit acquires starting points and ending points of each straight line as the cutting target points when the cutting path is formed of one more straight lines;
a robot position calculation unit configured to calculate a current cutting position of a surgical robot among the cutting target points based on surgery progress of the surgical robot, wherein the robot position calculation unit calculates an estimated cutting position which is estimated based on a cutting speed of the surgical robot according to the surgery plan information and a distance between the cutting target points, and an actual cutting position based on information received from a tracking device configured to track the position of the surgical robot, respectively;
a graphic user interface (GUI) providing unit configured to generate graphics that represent surgery progress information comprising a current cutting position of the surgical robot and positions of the cutting target points on a virtual bone model corresponding to the surgical target bone, wherein the GUI providing unit generates figures respectively corresponding to the plurality of cutting target points, a cutting line formed by connecting the cutting target points, and figures respectively corresponding to the estimated cutting position of the surgical robot and the actual cutting position of the surgical robot;
a display unit configured to display the virtual bone model and the surgery progress information; and
a view switching unit configured to automatically switch a view of the virtual bone model according to parts of the surgical target bone that undergoes cutting by the surgical robot, a position of robot arm of the surgical robot with respect to the surgical target bone, and a direction changed state of surgical tool.
