This ultrasound-guided method and device employs minimally invasive techniques, requiring only a small incision in the fracture area. Through this incision, a specially designed flexible bandage is precisely inserted and wrapped around the fractured rib using blunt dissection to avoid muscle tissue. Once tightened, the bandage provides continuous and stable external tension to the precisely reduced fracture ends, effectively counteracting the traction tension generated by respiratory movements and ensuring that the fractured rib maintains ideal alignment throughout the healing process. This technique avoids the extensive muscle stripping required in traditional surgery, significantly reducing intraoperative bleeding and postoperative pain, facilitating early ambulation, and greatly reducing the risk of complications such as pulmonary infection, achieving the treatment goal of minimal trauma and rapid recovery.
