Target spot tool and master-slave surgical robot test system

The utility model provides a target spot tool and a master-slave surgical robot test system, and relates to the technical field of master-slave control surgical machines. The target spot tool comprises a target spot structure, a rod-shaped structure and a connecting base, the target spot structure and the connecting base are located at the two ends of the rod-shaped structure in the length direction respectively and connected with the rod-shaped structure respectively, and the connecting base is suitable for being connected with a rotating structure of a master-slave surgical robot. The target structure is provided with at least one target used for calibrating space coordinates. According to the target spot tool, the rotating structure rotates at multiple positions, the space coordinates of the target spots are measured through the space measuring equipment, points on the rotating axis of the rotating structure can be found out, and then the position of the rotating axis of the rotating structure is found out
