Abstract

A master interface and a driving method for a surgical robot are disclosed. The master interface is mounted on a master robot, to manipulate a slave robot connected with the master robot, and includes: a main handle coupled to the master robot; a sub-handle coupled to the main handle; a first processor configured to generate a first signal in correspondence with user manipulation on the main handle; and a second processor configured to generate a second signal in correspondence with user manipulation on the sub-handle, where the first signal and the second signal are transmitted to the slave robot independently. As the interface for the surgical master robot includes not only the handle (main handle) for manipulating the robot arm, but also an additional controller (sub-handle) for a laparoscope, etc., the operator is able to simultaneously manipulate the laparoscope, etc., while manipulating the handle, without having to stop manipulating the handle or perform an additional action separately. The sub-handle may be detachably coupled to the main handle, so that the laparoscope, etc., may be manipulated separately by an assistant when necessary.
