Abstract
The invention discloses an acetabulum prosthesis, which is used to replace bone tumor in an acetabulum, and comprises an inner liner (4) which is sleeved outside a ball head of a femoral head, an acetabulum cup (3) is sleeved outside the inner liner (4), the inner liner (4) can rotate between a ball head of a femoral stem and the acetabulum cup (3), and the size of an opening of the acetabulum cup (3) is adjusted to prevent the acetabulum prosthesis from dislocating. The acetabulum prosthesis can be combined with an acetabular bone which is arranged in a patient body, is more firm to fix, is large in activity angle range, and is prevented from dislocating. The acetabulum prosthesis can be assembled at random according to situations of different patients, and meets the demands of different patients. The acetabulum prosthesis can protect limbs for patients, meets the demands of different positions of osteotomy in acetabulum surgery of hip joints, is identified with an original acetabulum position of in a patient body and an angle physical line, and can effectively and reliably rebuild functions of bodies.
Description
Technical field
The present invention relates to a kind of medical prosthesis, particularly relate to the acetabular component of bone tumor in a kind of alternative pelvis acetabular bone.
Background technology
Because pathological changes can cause pelvis malignant bone tumor on the pelvis of human body, reply bone tumor is excised, and should reach thorough tumor resection, reduce the generation of complication as far as possible and rebuild reliable and effective function during excision.
Because pelvic tumor resection reconstruction operations is complicated, therefore should carefully analyze the image data of patient in the preoperative, in the bone of specifying tumor and the scope of Gu Wai soft mass, present stage, a lot of prosthese can not reach the standard of above-mentioned requirements.
Summary of the invention
The object of the present invention is to provide a kind of acetabular component replaced bone tumor, prevent dislocation.
For achieving the above object, the concrete technical scheme of a kind of acetabular component of the present invention is:
A kind of acetabular component, for replacing bone tumor in acetabular bone, comprise the liner being set in femoral head bulb outside, the outer cover of liner is provided with acetabular cup, liner can rotate between femoral stem bulb and acetabular cup, prevents acetabular component from dislocating to regulate the openings of sizes of acetabular cup.
Further, the both sides of acetabular cup outside are connected to the holder wing and fixture, and acetabular cup is inserted in acetabular bone by holder wing fixture with fixing acetabular component.
Further, be provided with conehead in the holder wing, the outside wall surface of acetabular cup is provided with groove, and conehead can rotate in groove, and acetabular cup can rotate relative to the holder wing with the installation site regulating acetabular component.
Further, the outside wall surface of acetabular cup is provided with chain joint, and acetabular cup is connected with fixture by chain joint, and chain joint can rotate in fixture, and acetabular cup can rotate relative to fixture with the installation site regulating acetabular component.
Further, the holder wing is bone trabecula, and acetabular bone can be grown in bone trabecula, merges to make acetabular component and acetabular bone.
The advantage of a kind of acetabular component of the present invention is:
1) acetabular component can merge with the acetabular bone bone photo in patient body, and acetabular component is fixing more firm;
2) the activity point of view scope of acetabular bone is comparatively large, prevents acetabular component to dislocate;
3) according to any assembly acetabular component of the situation of different patient, the acetabular component demand of different patient can be met;
4) can be patient and protect limb, meet the position of different osteotomy in hip joint acetabular surgery art, acetabular component is consistent with the acetabular bone position in original patient body and the angle human body line of force, and the function in body can effectively also be rebuild reliably.
Accompanying drawing explanation
Fig. 1 is the structural representation of acetabular component of the present invention;
Fig. 2 is the side view of acetabular component of the present invention.
Detailed description of the invention
In order to better understand object of the present invention, structure and function, below in conjunction with accompanying drawing, further detailed description is done to a kind of acetabular component of the present invention.
As depicted in figs. 1 and 2, it shows for a kind of acetabular component of the present invention, for to implant in acetabular bone and to replace bone tumor part, comprise the liner 4 being set in femoral head bulb (not shown) outside, the outer cover of liner 4 is provided with acetabular cup 3, liner 4 can rotate between femoral stem bulb and acetabular cup 3, and to regulate the openings of sizes of acetabular cup 3 to prevent acetabular component from dislocating, acetabular component activity point of view scope is larger.Wherein, the outside wall surface of liner 4 and the internal face of acetabular cup 3 are shiny surface, reduce friction, add the service life in joint.
Further, the holder wing 1 is bone trabecula, and acetabular bone can be grown in bone trabecula, to make acetabular component and acetabular bone merge, fixing more firm.
Further, one end of acetabular cup 3 outside is connected with the bionic-type holder wing 1, inserted in acetabular bone by the bionic-type holder wing 1 with fixing acetabular component, dovetail aerofoil profile conehead 2 is provided with in the holder wing 1, acetabular cup 1 is provided with dove-tail form groove 31, conehead 2 can embed in groove 31, and the holder wing 1 is connected with acetabular cup by conehead 2.In addition, conehead 2 can rotate in groove 31, and acetabular cup 3 rotates relative to the holder wing 1, to regulate the installation site of acetabular component, when different osteotomy, by adjusting the position of acetabular component to ensure the line of force of acetabular bone and the consistent of human body.
Further, the other end of acetabular cup 3 outside is connected with pubis Medullary fixation part 6, inserted in acetabular bone by fixture 6 with fixing acetabular component, the outer wall of acetabular cup 3 is provided with bulb type pubis chain joint 5, chain joint 5 is set in fixture 6, and can rotate in fixture 6, acetabular cup 3 can rotate relative to fixture, to regulate the setting angle of acetabular component, when different osteotomy, by adjusting the position of acetabular component to ensure the line of force of acetabular bone and the consistent of human body.Wherein, the pubis Medullary fixation part 6 of different length, specification can be equipped with according to the demand of patient.
A kind of acetabular component of the present invention, can merge with the acetabular bone bone photo in patient body, and acetabular component is fixing more firm; The activity point of view scope of acetabular bone is comparatively large, prevents acetabular component to dislocate; According to any assembly acetabular component of the situation of different patient, the acetabular component demand of different patient can be met; Can be patient and protect limb, meet the position of different osteotomy in hip joint acetabular surgery art, acetabular component is consistent with the acetabular bone position in original patient body and the angle human body line of force, and the function in body can effectively also be rebuild reliably.
Further describe invention has been by specific embodiment above; but it should be understood that; here concrete description; should not be construed as the restriction to the spirit and scope of the invention; one of ordinary skilled in the art to the various amendments that above-described embodiment is made, belongs to the scope that the present invention protects after reading this specification.
