AI Technical Summary
In the emergency treatment of distal radius fractures, the lack of professional assistants makes the reduction operation difficult. Assistance from non-professionals may cause additional pain or secondary injury, affecting the quality of reduction and increasing the probability of surgical treatment.
A rotatable distal radius fracture fixation device was designed, including an arm fixation device, an adjustment device, and a palm fixation device. It can stably traction the patient's limb, adjust it to the angle of the patient's limb, replace an assistant for fixation, and reduce the need for manpower.
It enables independent repositioning operations, reduces reliance on additional assistants, improves the smoothness of the treatment process, avoids secondary damage, adapts to different patient structures, and ensures traction stability.
