AI Technical Summary
Traditional osteotomy techniques pose risks of osteotomy plane displacement and neurovascular bundle laceration when treating long tubular bone lesions. They also lack effective protection of surrounding soft tissues, leading to problems such as intraoperative bleeding and postoperative adhesions.
A soft tissue protector for long tubular bone osteotomy was designed, which adopts an arc-shaped hollow hook and an isosceles triangular handle structure, combined with an anti-slip sleeve, to optimize the human anatomy, provide a stable field of vision and physical isolation, reduce the contact between the saw blade and soft tissue, distribute the grip pressure, and improve the stability of operation.
It enables precise osteotomy of long tubular bones, expands the surgical field, reduces osteotomy risks, reduces bleeding and adhesions, and improves operational comfort and safety.
