Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an orthopedic clinical hip joint surgery bracket. Background Technology

[0002] Hip surgery refers to total hip replacement, which is often used for patients with stage IV femoral head necrosis or stage IV osteoarthritis. The procedure begins with preparation of the acetabulum, involving the removal of excess bone and the insertion of an acetabular cup. Next, preparation of the femoral side is performed, including a femoral neck osteotomy. The femoral head is removed, a femoral stem prosthesis is inserted, and the femoral head and acetabular pads are installed. Finally, the hip joint is reduced.

[0003] During hip surgery, the patient needs to lie on their side on the operating table. In this position, the pelvic support and legs need to be stabilized to facilitate the procedure. Existing surgical supports cannot adequately define the surgical position for patients of different body types, and they also offer poor comfort during use.

[0004] This invention addresses these issues by proposing an orthopedic clinical hip joint surgical brace, aiming to solve the aforementioned problems and enabling the surgical brace to effectively limit the surgical position for patients of different body types, resulting in greater comfort during use.
