Embodiment Construction

[0062] Examples see Figure 1-3 As shown, this kind of hip orthopedic and femoral extender is composed of bone fixation bracket, steel pin fixation clip connected to the bone fixation bracket, and steel pin clamped in the steel pin fixation clip, wherein the bone fixation bracket consists of the distal The stent and the proximal stent are composed of two parts.

[0063] The distal support includes a distal hole C-shaped ring 1, a proximal hole C-shaped ring 2 arranged above the distal hole C-shaped ring, and a C-shaped ring connected to the distal hole C-shaped ring and the proximal hole. Several draft rods 3 between the C-shaped rings. As the most preferred embodiment, one end of the stretching rod 3 is fixedly connected to the C-shaped ring 1 of the distal hole, and the other end is hingedly connected to the C-shaped ring 2 of the proximal hole. The distal brace has multiple functions of orthopedics and limb lengthening.

[0064] The proximal support includes one to two t...

Abstract

The invention provides a hip joint correction and thighbone extender, consisting of a bone external fixation support, a steel needle fixation clamp connected to the bone external fixation support, and a steel needle clamped in the steel needle fixation clamp, wherein the bone external fixation support consists of a far side support and a near side support, the far side support comprises a far end hole C-shaped ring, a near end hole C-shaped ring arranged above the far end hole C-shaped ring, and a plurality of traction rods connected between the far end hole C-shaped ring and the near end hole C-shaped ring, and the near side support comprises one to two tubular connecting rods connected above the near end hole C-shaped ring, and an arc-shaped bow connected between the tubular connecting rods and the near end hole C-shaped ring. The hip joint correction and thighbone extender has three functions of hip joint correction, femoral fracture treatment and thighbone extension, meets the mechanics biological environment of truncation bone correction and fixation and thighbone slow extension, and is favorable for growth of new bones and function optimization and rebuilding during fracture healing and limb extension.

Description

technical field [0001] The invention relates to an external fixator for bone, in particular to an external fixator for bone applied at hip joint and femur. Background technique [0002] 1. External fixation technique in the treatment of hip joint disease. The treatment of hip joint disease with external fixation technology mostly refers to the application of pelvic support osteotomy (Ilizarov technique) to treat chronic and refractory hip joint diseases such as structural abnormalities of the hip joint, chronic pain and dysfunction, such as congenital dislocation of the hip joint, femoral Osteonecrosis, pseudarthrosis of the femoral neck, and ankylosis of the hip. Pelvic support osteotomy has the advantages of small trauma, no blood transfusion, simple operation, definite curative effect, long-lasting effect, and few complications. It is also an ideal choice for patients with hip joint disease who have been replaced, and for cases where artificial replacement has failed. ...
