| Zusammenfassung: | The utility model discloses a cancellous bone screw thread detection tool which comprises a base. First electric push rods are arranged at the four corners of the top of the base, a placement block is arranged on the inner side of one end of each first electric push rod, dismounting mechanisms are symmetrically arranged in the placement blocks, a detection block is installed in an installation groove, and a detection mechanism is arranged at one end in the detection block. The detection mechanism is arranged at one end in the detection block, when the cancellous bone screw passes through the pressure sensor, the bottom of the pressure sensor can be attached to threads on the surface of the cancellous bone screw to generate pressure, and when the threads on the surface of the cancellous bone screw are lost, values sensed by the cancellous bone screw and the pressure sensor can change, so that the cancellous bone screw can be detected. The pressure sensor sends a detected signal to the interior of the intellige |
