1. A navigation surgical system, comprising a robotic system and a navigation system communicatively connected to the robotic system, the robotic system comprising a robotic arm, the navigation system comprising a navigation tracking device,
wherein the robotic system has a robotic-arm based coordinate system established according to the robotic arm, and the robotic-arm based coordinate system is configured to be fixed relative to a supporting device;
wherein the navigation system has a reference coordinate system that is recognizable by the navigation tracking device, and the reference coordinate system is configured to be fixed relative to the supporting device;
wherein the navigation surgical system is configured to determine a relative position between the robotic arm and the navigation tracking device according to a relative position between the robotic-arm based coordinate system and the supporting device, and a relative position between the reference coordinate system and the supporting device without need to install a target on the robotic arm for registering the robotic arm; and
the navigation surgical system further comprising a robotic-arm fixing device, wherein the robotic arm is fixed on the supporting device by the robotic-arm fixing device; wherein the robotic-arm fixing device comprises a vertical frame and a horizontal cantilever; and wherein the frame has a first end fixed on the supporting device and a second end connected to a first end of the horizontal cantilever, and a second end of the horizontal cantilever is connected to the robotic arm.
