Abstract
The utility model relates to an axis joint acetabular cup. The axis joint acetabular cup is of a hemispherical cup shape in appearance and is formed by a cup edge (1), a cup body (2) and a cup bottom (4), wherein the cup edge (1) slightly protrudes towards the cup body (2) by 3-15mm and is shaped like a ring, the cup body (2) is of a hemispherical shape, the internal diameter of the cup body (2) is 30-60mm, and the thickness of the cup body (2) is 3-15mm; the cup bottom (4) is a columnar body or a cylindrical shape, the diameter of the cup bottom ranges from one tenth of the diameter of the cup body (2) to the diameter of the cup body (2), and the height of the cup bottom (4) is 5-30mm; multihole pieces are selected to serve as the cup edge (1) and the cup body (2), and porosity of the cup edge (1) and the cup body (2) is 60-70%. The axis joint acetabular cup has the advantages of relative stability, certain mobility and the like, the application range is wide, mechanical performance is met, the service life of the axis joint acetabular cup is greatly prolonged, and implantation comfort of the axis joint acetabular cup is greatly improved.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of artificial acetabular cup that is used for the treatment of hip joint disease.
Background technology
In prior art, for the treatment of hip joint disease, often adopt cochrome to make a metal implant, its profile is cup-shaped, is referred to as metal cup, has another name called Acetabulum cap etc.Use the surgical incision hip joint in application, it is placed between femoral head and acetabular bone, this operation is called hip joint metal cup plasty, and it makes many patients that lose joint movement function because of hip joint disease regain movable hip joint.Subsequently, the two cup of the hip joint that someone proposes again artificial joint replacement, be that the Acetabulum cap made from ultra high molecular polyethylene covers acetabular bone, with the spherical metal cup, covers femoral head.In recent years, replacement of total hip occurred, acetabular bone covers with the ultra high molecular polyethylene Acetabulum cap, and femoral head is replaced with artificial thigh bone.Implant between femoral head and primary acetabulum, reach above-mentioned metal cup, Acetabulum cap etc., or dissociate therebetween, or be fixed on acetabular bone with bone cement, screw etc.The former easily skids off, latter's operation technique complexity.And, in prior art, select and the structure of artificial hip joint cup arranges the certain defect of upper existence, after causing that the artificial hip joint cup is long-time and using and tissue there will be repulsion, biocompatibility is poor and affect its service life.
The utility model content
The purpose of this utility model be to provide a kind of implantation easily, good stability, biocompatibility be better, and the artificial acetabular cup of certain mobility is arranged again.
The purpose of this utility model is to realize like this:
A kind of artificial acetabular cup, its profile is the hemisphere cup-shaped, and it is comprised of margin of optic cup, cup and the cup ends three part, and wherein margin of optic cup is slightly to the outstanding 3～15mm of cup, and is one circular, and it is hemispherical that cup is, and interior diameter is 30～60mm, and thick is 3～15mm; The cup end is a cylinder or cylinder, and diameter is identical with the cup diameter to being 1/10th of its diameter, and height is 5～30mm; Described margin of optic cup and cup are all selected the porous tantalum product, and its porosity is 60 ~ 70%.
Above-mentioned margin of optic cup and cup, all preferably adopt the porous tantalum product, and the cup end and cup be formed with electron beam weld by electron beam welding, and this connected mode intensity is high, solid and reliable.Find that through studying for a long period of time the porous tantalum product, in the biocompatibility that has greatly improved this artificial acetabular cup, has also well met its mechanical property, greatly improved its service life and implanted comfort level.Above-mentioned porous tantalum product, can adopt the preparations such as foam dipping method, die pressing.
This artificial acetabular cup is the hemisphere cup-shaped, at the bottom of its bottom has glass, is one cylindric or cylindric, and the rim of a cup periphery has outwards outstanding margin of optic cup.The margin of optic cup of this artificial acetabular cup and cup, available have that high-strength stainless steel or ultra high molecular polyethylene or other materials are made preferably with histocompatibility.
Principle of the present utility model is to form an artificial joint rotated around its axle center between this implant and primary acetabulum, can be referred to as the joint, axle center.Joint between this implant and primary acetabulum contacts, and makes it not only relatively stable, and also has certain mobility.
The utlity model has following beneficial effect:
This utility model except alternative metal cup as hip joint metal cup plasty, also can be used as the articular surface displacement of acetabular bone one side in hip joint two cup artificial joint replacement and replacement of total hip or cover, have the characteristics of relative stability and certain aspects such as mobility concurrently, wide accommodation.And margin of optic cup and cup by artificial acetabular cup are set to the porous tantalum product, greatly improved the biocompatibility of this artificial acetabular cup, also well met its mechanical property simultaneously, greatly improved the service life of this artificial acetabular cup and implanted comfort level.In addition, the cup end and cup form by electron beam welding, and its connected mode intensity is high, solid and reliable.In the actual operation application, this utility model is simple to operate, little to the damage of acetabular bone, and Cementless or other materials are fixed.
The accompanying drawing explanation
The profilograph that Fig. 1 is artificial acetabular cup described in this utility model embodiment 1.Wherein, 1 is margin of optic cup, and 2 is cup, and 3 is electron beam weld, and 4 is the cup end.
The specific embodiment
Be below this utility model preferred embodiment, and be not intended to limit protection domain of the present utility model.
Embodiment 1
As shown in Figure 1: a kind of artificial acetabular cup, its profile is the hemisphere cup-shaped, and it is comprised of margin of optic cup 1, cup 2 and the cup ends 4 three part, and wherein margin of optic cup 1 is slightly to the outstanding 3mm of cup 2, and is one circular, and cup 2 is hemispherical, and interior diameter is 30mm, and thick is 3mm; The cup end 4 is a cylinder, and diameter is 3mm, and height is 5mm; Margin of optic cup 1 and cup 2 are the porous tantalum product, and its porosity is 60 ~ 70%, and the cup end 4 is formed with electron beam weld 3 with cup 2 by electron beam welding.
Embodiment 2
A kind of artificial acetabular cup, its margin of optic cup 1 is slightly to the outstanding 15mm of cup 2, and is one circular, and cup 2 is hemispherical, and interior diameter is 60mm, and thick is 10mm; The cup end 4 is a cylinder, and diameter is 30mm, and height is 30mm; Other structure arranges all identical with embodiment 1.
