Tooling detection tool and detection method for spinal pedicle screw

The invention discloses a spinal pedicle screw tool detection tool and a detection method, and belongs to the technical field of medical instruments, and the spinal pedicle screw tool detection tool comprises an inner spherical diameter measurement detection tool which is used for detecting the diameter of an inner spherical surface, matched with a gasket or a ball nail, in a nail seat of a pedicle screw. The inner ball diameter measuring gauge comprises a middle shaft rod, a lower large wafer is fixedly arranged at the front end of the middle shaft rod, an upper small wafer parallel to the lower large wafer sleeves the middle shaft rod above the lower large wafer, an elastic piece used for keeping the lower large wafer and the upper small wafer in an open state is arranged between the lower large wafer and the upper small wafer, and the diameter of the lower large wafer is larger than that of the upper small wafer. The diameter of the lower large wafer and the diameter of the upper small wafer are both betwe
