In the first embodiment, as shown in fig. 1 to 4, an ulna styloid process auxiliary fracture reduction fixing pull hook comprises a first section body 1, a second section body 2 and a third section body 3 which are integrally formed in sequence, wherein the first section body 1 is in a drag hook shape and is used for being hooked on an ulna styloid process 52; the first section body 1 comprises two palladium nails 14 arranged at the tail ends of the first section body and a first gap 13 positioned between the two palladium nails 14, and the palladium nails 14 are used for being inserted into ligament gaps; the first segment body 1 is also provided with a first needle inlet hole 11 and a second needle inlet hole 12 which are communicated with the ulna styloid process 52, and the first needle inlet hole 11 and the second needle inlet hole 12 can guide a kirschner wire to penetrate through the ulna main body 51, so that a steel needle can be connected with the ulna main body 51 and the ulna styloid process 52.

The ulnar styloid process 52 has ligaments that, when the ulnar styloid process 52 breaks, can dislodge the ulnar styloid process 52 and make it difficult to pull back into place. The shape of the inner contour of the first section 1 of the instrument is fitted to the ulna styloid process 52 as much as possible, so that accidental injury to the ulna styloid process 52 caused by a traditional clamp can be effectively avoided. By using the instrument, the ulna styloid process 52 can be easily pulled back to the original position, the ligament injury can be avoided, the kirschner wire puncture and the steel nail driving-in can be accurately completed, and the injury to the ulna styloid process 52 caused by multiple punctures is avoided.

In an embodiment, as shown in fig. 1 to 4, the second segment 2 is provided with a lever support 21 against the ulnar body 51. By applying pressure to the third segment 3, the instrument can be pulled toward the edge of the ulnar body 51 with the lever support 21 as a fulcrum.

In an embodiment, as shown in fig. 2 to 4, the third segment body 3 includes an inclined segment 31 gradually distant from the second segment body 2 from the ulnar body 51.
