Abstract
The utility model discloses an acetabulum cup for bone crafting for repairing defective acetabulums, which comprises an acetabulum cup body. A plurality of adjacent projections are fixed to the edge of the acetabulum cup body and extend perpendicularly outwards along the edge of the acetabulum cup body, and a U-shaped clamping groove is disposed on each of upper and lower end surfaces of the projections along tangential directions of the edge of the acetabulum cup body. The projections with the clamping grooves are disposed at the edge of the acetabulum cup, a titanium mesh is fixed on a bone defect portion on the outer upper side of the acetabulum of a patient and used for supporting bone mud crafted into the bone defect portion, and accordingly the bone mud for bone crafting of the bone defect portion on the outer upper side of the acetabulum of the patient is stabilized. The acetabulum cup in the design can be specially applied to acetabulums with dysplasia of developmental hip joints, and after the true rotational center of the acetabulum is rebuilt, the bone defect portion at the outer upper edge of the acetabulum is filled by means of bone crafting.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of bone grafting reparation (acetabular cup of the damaged acetabular bone of adult hair fertility hip dysplasia patient acetabular bone outer rim bone that is used for.
Background technology
(Developmental Dislocation of the Hip DDH) is one of Orthopeadic Surgery common and complex disease to developmental dislocation of hip joint, and the patient is owing to acetabular dysplasia, and hip joint head mortar joint is asymmetric; The final secondary coxarthrosis often that lapses to,, need carry out the whole coxa substitution operation, and DDH patient; Acetabular dysplasia often, the bone under-reserve, particularly at the wound edge of acetabular bone, partially before or partially after; If this part bone damaged little (＜40%), the acetabular fossa polishing is darker, does not generally influence the installation and the incipient stability of acetabular bone; But this part bone is damaged often again near the heavy burden district of acetabular bone, and perhaps part has been the district of bearing a heavy burden, if can not repair; Can there be certain influence in acetabular bone stability to from now on, after can influencing artificial hip joint and installing at body life time, if therefore can repair preferably reparation.And existing acetabular cup have two cups acetabular bone, have belt loop also can be used for the reparation that exists the acetabular bone bone damaged with the fixed acetabular bone rest of screw; But what have also need use bone cement; The additional screw that need to rely on to the defective bone amount that has is fixed, and resembles the partial installation of this use titanium net, does not influence the design that original biotype is press-fitted acetabular cup and does not appear in the newspapers; And this design is the special circumstances that reset to DDH patient's acetabular bone fully, is " to make to measure " for this reason.Design is succinct, and is motivated, solved the typical acetabular cup and implanted DDH patient after the acetabular cavity of polishing; The outer upper section bone of acetabular bone is damaged; Can't fixed problem, and this invention, through the method for titanium net can be installed in the acetabular bone outer rim; Can make the bone mud bone grafting of inserting keep original position, play a supporting role.
Therefore, keep the bone grafting bone mud acetabular bone outside on the stable problem of quadrate bone defect be that the present inventor is devoted to study and deal with problems.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art and a kind of acetabular cup that is used for bone grafting repair deficiency property acetabular bone is provided; The card of this acetabular cup through being located at its edge insert with fixing titanium net, solved the stable problem that acetabular bone is gone up quadrate bone defect bone grafting bone mud outward.
The purpose of this utility model is achieved in that
A kind of acetabular cup that is used for bone grafting repair deficiency property acetabular bone of this utility model; Comprise the acetabular cup cup; The edge of said acetabular cup cup is fixed with several adjacent projections; This projection stretches out along the edge-perpendicular of said acetabular cup cup, is respectively equipped with a U-shaped draw-in groove on the upper and lower end face of said projection and along the tangential direction at said acetabular cup cup edge.
The above-mentioned acetabular cup that is used for bone grafting repair deficiency property acetabular bone, wherein, the top of said acetabular cup cup is provided with at least two fastener holes.
The advantage of this utility model: simple in structure; Reasonable in design, novel; This utility model has the projection of draw-in groove through several that are located at its edge; The titanium net is fixed in acetabular bone goes up the quadrate bone defect outward, be used for the bone mud that support is implanted above-mentioned bone defect, thereby solved the stable problem that acetabular bone is gone up quadrate bone defect bone grafting bone mud outward.This design can be applied to the acetabular bone of adult hair fertility hip dysplasia especially, after rebuilding the real center of rotation of acetabular bone, and the damaged portion of bone of filling up the outer upper edge portion of acetabular bone through bone grafting.
Description of drawings
Fig. 1 is the structural representation of this utility model.
The specific embodiment
To combine accompanying drawing that this utility model is described further below.
See also Fig. 1; The acetabular cup that this utility model is used for bone grafting repair deficiency property acetabular bone has been shown among the figure; This acetabular cup comprises acetabular cup cup 1; The edge of acetabular cup cup 1 is fixed with 3 adjacent projections 2, and each projection 2 all stretches out along the edge-perpendicular of acetabular cup cup 1, is provided with a U-shaped draw-in groove 22 on the upper surface of projection 2 and along the tangential direction at acetabular cup cup 1 edge; Be provided with a U-shaped draw-in groove 23 on the lower surface of projection 2 and along the tangential direction at acetabular cup cup 1 edge, the top of acetabular cup cup 1 is provided with 4 fastener holes 11.
Operation principle: during the whole coxa substitution operation; Can this utility model acetabular cup be fixed in the acetabular cavity and (can use the screw that passes fastener hole 11 to fix through being press-fitted technology; Also can not make and be screwed) put in place, projection 2 is gone up the quadrate bone defect outside acetabular bone, fill the damaged portion of bone between acetabular bone outer rim and manual acetabulum with a small amount of bone mud then; One side with the titanium net is stuck on U-shaped draw-in groove 22 or 23 at last, with the bone mud of support implantation.
Above embodiment only supplies to explain the usefulness of this utility model; But not to the restriction of this utility model; The technical staff in relevant technologies field under the situation of spirit that does not break away from this utility model and scope, can also make various conversion or modification; Therefore all technical schemes that are equal to also should belong to the category of this utility model, should be limited each claim.
Claims (2)
1. acetabular cup that is used for bone grafting repair deficiency property acetabular bone; Comprise the acetabular cup cup; It is characterized in that; The edge of said acetabular cup cup is fixed with several adjacent projections, and this projection stretches out along the edge-perpendicular of said acetabular cup cup, is respectively equipped with a U-shaped draw-in groove on the upper and lower end face of said projection and along the tangential direction at said acetabular cup cup edge.
