Technical Field

[0001] This utility model relates to the field of orthopedic rehabilitation device technology, and in particular to an orthopedic lower limb traction device. Background Technology

[0002] Lower limb fractures are common in orthopedics, accounting for approximately 40% of all fractures. Lower limb traction is an important treatment method for lower limb fractures, dislocations, and some joint diseases.2 Traction can immobilize the affected limb, reduce local irritation, and mitigate the spread of inflammation; maintain the limb in a functional position, stabilize the fracture ends, and promote fracture reduction and healing; relieve muscle spasms, improve venous blood return, and eliminate limb swelling; and correct and prevent joint deformities caused by muscle spasms. However, lower limb traction devices require multiple power devices to assist patients in leg rehabilitation exercises, increasing energy consumption. Therefore, we propose an orthopedic lower limb traction device. Utility Model Content
