Locking support for treating femoral intertrochanteric fracture through minimally invasive therapy

Abstract

The invention relates to medical apparatus and instruments, in particular to a locking support for treating femoral intertrochanteric fracture through minimally invasive therapy. The locking support comprises a locking rod body and four locking screws. The locking rod body is cylindrical, the near end of the locking rod body is provided with radian, and the locking rod body is provided with four locking threaded holes. The two threaded holes in the near end are inclined by 130 degrees, and the two threaded holes in the far end are in a perpendicular shape. The two screws at the near end are hollow cancellous bone locking screws, and the two screws at the far end are cortical bone locking screws. According to the locking support, compared with an existing steel plate, the locking rod is designed to be cylindrical, the contact area of the locking rod and the bone is reduced, minimally invasive percutaneous implantation is conducted easily, only four screws are needed to conduct locking, and the locking support has the advantages of being reasonable in design, simple in structure, firm to fix, convenient to operate and the like. By means of the technology, no fracture end needs to be exposed, so that wounds and blood loss in operation are reduced, the operation risk is lowered, and blood supply, periosteum growth and postoperative recovery are greatly improved.

Description

technical field [0001] The invention relates to a medical device, in particular to a locking bracket for minimally invasive treatment of intertrochanteric fractures of the femur. Background technique [0002] At present, there is no unified gold standard for the treatment of intertrochanteric fractures. Although external fixation fixation is less invasive, it takes a long time to fix, difficult to nurse, and life is inconvenient. It is often accompanied by infection of the screw tract and stiffness of the knee joint. If locking plates or intramedullary nails are used for fixation, although a good fixation effect can be achieved, surgical open reduction or reaming is required, which has the disadvantages of large trauma, blood loss, and high risk. How to provide a safer, more efficient, and more effective fixation method for patients with intertrochanteric fractures, especially elderly patients, is a difficult problem in current treatment.

Problems solved by technology

[0002] At present, there is no unified gold standard for the treatment of intertrochanteric fractures. Although the external fixation treatment is less invasive, it takes a long time to fix, difficult to nurse, and life is inconvenient. It is often accompanied by screw tract infection and knee joint stiffness.

If locking plates or intramedullary nails are used for fixation, although good fixation can be achieved, surgical open reduction or reaming is required, which has the disadvantages of large trauma, blood loss, and high risk.
