Ulna coracoid process fracture angle measuring device

The utility model relates to the technical field, in particular to an ulna coracoid process fracture angle measuring device which comprises a grab handle, a connecting rod, a flexible gasket, a dial, a scale pointer, fracture fragments and ulna. The bottom of the grab handle is connected with the top of the connecting rod. The bottom of the connecting rod is rotationally connected with the dial. The flexible gasket is sleeved on the peripheral wall of the dial; and the scale pointer is rotationally arranged on the dial. According to the ulna articular surface measuring device, the flexible gasket is replaced with a proper model according to the size of an ulna articular surface, the handle is held by hand to place the measuring device into the articular surface, the minimum position on the dial is aligned with the edge position of the articular surface, the scale pointer is shifted to be aligned with the initial position of a fracture fragment, and the angle value of the complete part of the articular surface
