Abstract
The utility model provides a hip prosthesis, which consists of a femoral neck, a pterygoid tuberosity and a femoral shaft, wherein the cross section of the femoral neck is elliptical. The hip prosthesis has the advantages that the femoral neck has a large scope of activities, the prosthesis can be implanted stably, and the effective counter rotation performance is guaranteed.
Description
Technical field
This utility model relates to a kind of surgery implanting prosthetic, particularly a kind of hip prosthesis.
Background technology
Existing advanced hip prosthesis, form by column type neck of femur, proximal end face micropore and far-end circular cone, has advantage easy to process, that the construction cycle is short, but but find in actual use, existing hip prosthesis, behind implant into body, hip prosthesis is movable between the angle of column type neck of femur and the formation of acetabular bone edge, the femur range of activity is limited, increased the risk of acetabular bone dislocation, and be unfavorable for that bone grows into, loosening easily, the coupling of far-end circular cone and pulp cavity is not good, can influence the pulp cavity blood supply.
This shows that above-mentioned existing hip prosthesis obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.It is big how to develop a kind of neck of femur range of activity, and prosthese is implanted stable, and the hip prosthesis of effective anti-rotational new structure, is one of current important subject in this area.
The utility model content
The purpose of this utility model is, overcomes the defective that existing hip prosthesis exists, and a kind of hip prosthesis of new structure is provided, technical problem to be solved is to make its neck of femur range of activity big, prosthese is implanted stable, and effectively anti-rotation, thereby is suitable for practicality more.
The purpose of this utility model and to solve its technical problem be to adopt following technical scheme to realize.According to a kind of hip prosthesis that the utility model proposes, to form by neck of femur, the tuberosity wing and femoral stem, the cross section of described neck of femur is oval.
The purpose of this utility model and solve its technical problem and can also be further achieved by the following technical measures.
Aforesaid hip prosthesis, the proximal end of described femoral stem is provided with microflute.
Aforesaid hip prosthesis, the wide 0.5～2mm of described microflute, dark 0.5～1.5mm.
Aforesaid hip prosthesis, the cross section of described femoral stem is the rectangle of band lead angle.
Aforesaid hip prosthesis, the sagittal plane of described femoral stem are provided with ridge shape projection.
Aforesaid hip prosthesis, the sagittal plane of described femoral stem respectively are provided with 2～6 ridge shape projections.
Aforesaid hip prosthesis, described ridge shape rising height is 0.5～3mm.
Aforesaid hip prosthesis, the far-end of described femoral stem is the design of polishing sub warhead.
Aforesaid hip prosthesis, the height of described sub warhead design is 8-30mm, the maximum cross section diameter is 6-15mm.
Aforesaid hip prosthesis, the cross section major axis of described neck of femur be greater than minor axis 1-5mm, tuberosity wing broadening 2～6mm.
This utility model compared with prior art has following tangible advantage and beneficial effect at least:
1, this utility model hip prosthesis, neck of femur is an oblong, has increased the range of activity of prosthese.
2, this utility model hip prosthesis adopts the design of near-end microflute, and bone grafting automatically in the process of prosthese implant into body has been guaranteed prosthese stablizing after implanting.
3, this utility model hip prosthesis, cross section are approximate rectangular, and position, both sides ridge shape projection has splendid anti-rotation and primary stability.
4, this utility model hip prosthesis, far-end adopt the design of polishing type sub warhead, have avoided and the cortex bump, and maximum possible has reduced big skelalgia and cortex wearing and tearing.
5, this utility model hip prosthesis, the design of the tuberosity wing of broadening, strengthened prosthese anti-rotatory, increased the contact area of near-end prosthetic surface.
6, this utility model hip prosthesis, really according to patient's pulp cavity design, the better matching pulp cavity reaches better result of use, and can be made into all size adapting to different needs of patients, thereby more is suitable for practicality.
In sum, this utility model hip prosthesis, the neck of femur range of activity is big, and prosthese is implanted stable, and effectively anti-rotation.The utlity model has above-mentioned plurality of advantages and practical value, no matter it all has bigger improvement on product structure or function, obvious improvement is arranged technically, and produced handy and practical effect, and more existing hip prosthesis has outstanding effect, thereby is suitable for practicality more.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of description, and for above-mentioned and other purposes, feature and advantage of the present utility model can be become apparent, below especially exemplified by preferred embodiment, and conjunction with figs., be described in detail as follows.
Description of drawings
Fig. 1 is the structural representation of this utility model hip prosthesis.
Fig. 2 is the cross sectional representation of this utility model hip prosthesis femoral stem.
The specific embodiment
For further setting forth this utility model is to reach technological means and the effect that predetermined utility model purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, to according to its specific embodiment of hip prosthesis, structure, feature and the effect thereof that the utility model proposes, describe in detail as after.
See also shown in Figure 1ly, this utility model hip prosthesis is made up of neck of femur 1, the tuberosity wing 2 and femoral stem 3.
Wherein, the cross section of neck of femur 1 is oval, and major axis grows up and be about 1-5mm in minor axis, behind the implant into body, because therefore the front and back thinner thickness can increase the prosthese range of activity.
The tuberosity wing 2 is compared with the existing hip prosthesis of same model, adopts the broadening design, increases width 2～6mm.
The near-end of femoral stem 3 adopts microflute to design 31 groove widths, 0.5～2mm, groove depth 0.5～1.5mm, and groove is distributed near end of thighbone.Please cooperate and consult shown in Figure 2ly, the cross section of femoral stem 3 is the rectangle of band lead angle, and respectively is provided with 2-6 ridge shape projection 32 in the both sides sagittal plane, and ridge shape projection 32 highly is 0.5～3mm.The far-end of femoral stem 3 adopts polishing sub warhead design 33, and the height of sub warhead design 33 is 8-30mm, and the diameter of its maximum cross section is 6-15mm, and sub warhead design 33 can avoid the prosthese far-end to contact with cortical bone, thereby eases the pain.
The above, it only is preferred embodiment of the present utility model, be not that this utility model is done any pro forma restriction, though this utility model discloses as above with preferred embodiment, any those skilled in the art, make a little change or be modified to the equivalent embodiment of equivalent variations when the technology contents that can utilize above-mentioned announcement, all still belong in the scope of technical solutions of the utility model.
