AI Technical Summary
Existing orthopedic external fixators are difficult to maintain a suitable connection angle when fixing fracture ends, which can easily lead to misalignment and displacement of the fracture ends.
A connecting device was designed, comprising multiple connecting units and support units. Multi-angle adjustment and precise fixation are achieved through first, second and third adjustment mechanisms. Stable fixation of the bone needle is achieved by combining components such as guide rods, connecting rods, screws, sleeves and bolts.
It enables flexible adjustment and precise fixation of fracture ends at multiple angles, shortens fixation time, and improves the efficiency of fracture treatment.
