[0002] When pediatric surgeons are reducing children's broken bones, they need to use reduction forceps. After a fracture, the two broken bones will overlap due to the pulling of muscles. When reducing the broken bones, at least two reduction forceps are needed to clamp the two broken bones respectively, and the medical staff will pull the two ends of the bones apart to the reduction position and fix them with steel plates. The movement position of the two broken bones needs to be adjusted manually, making it difficult to align the two ends of the broken bones. Sometimes, after the broken bones are reduced, when the bone holding forceps are removed for steel plate fixation, the broken bones may return to their original dislocation state, which brings inconvenience to the doctor's work. Therefore, it is very important to design a pediatric orthopedic reduction forceps with an auxiliary positioning structure.
