Abstract
The utility model discloses a metal joint implant used for a hip joint. The metal joint implant used for the hip joint includes a metal joint hemisphere 1 and multiple pieces of sheet-shaped embossing 2 composed of porous tantalum. The sheet-shaped embossing 2 is welded on the metal joint hemisphere 1 and is distributed on the metal joint hemisphere 1 uniformly. The metal joint implant used for the hip joint with the above structure is good in bone combining performance, good in biocompatibility and stable and durable in use.
Description
Technical field
This utility model relates to a kind of hip joint metal acetabular implant, relates in particular to that a kind of synosteosis is strong, biocompatibility is high, firm durable hip joint metal acetabular implant.
Background technology
When being human hip generation pathological changes, passes through hip joint metal acetabular implant the replacement prosthesis of orthopaedics replacement operation implant into body hip joint.Existing hip joint metal acetabular implant surfaces mostly is coarse sprayed coating, though have bone to grow into during use, starts growth slow, the bone degree of depth deficiency of growing into, and synosteosis is not strong, cannot realize good fixing and firm lasting use.
Utility model content
In view of the foregoing defects the prior art has, this utility model aim to provide that a kind of synosteosis is strong, biocompatibility is high, firm durable hip joint metal acetabular implant.
To achieve these goals, this utility model by the following technical solutions: hip joint metal acetabular implant comprises a plurality of lamellar embossing that metal acetabular hemisphere face and porous tantalum form; Described lamellar embossing is welded on described metal acetabular hemisphere face; Described lamellar embossing is uniformly distributed along described metal acetabular hemisphere face.
As the improvement to the technical program, described lamellar embossing is regular hexagon.
Compared with the prior art, this utility model, owing to having adopted technique scheme, has improved the synosteosis of structure, has improved the biocompatibility of structure, has realized firm lasting use.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
In figure: 1 metal acetabular hemisphere face, 2 lamellar embossing.
The specific embodiment
Below by embodiment, this utility model is specifically described; be necessary to be pointed out that at this following examples are only for being further detailed this utility model; can not be interpreted as the restriction to this utility model protection domain, those skilled in the art can make some nonessential improvement and adjustment to this utility model according to foregoing.
Embodiment: a kind of hip joint metal acetabular implant, as shown in Figure 1, hip joint metal acetabular implant comprises a plurality of lamellar embossing 2 that metal acetabular hemisphere face 1 and porous tantalum form; Described lamellar embossing 2 is welded on described metal acetabular hemisphere face 1; Described lamellar embossing 2 is uniformly distributed along described metal acetabular hemisphere face 1.
Preferably, described lamellar embossing 2 is regular hexagon.
Lamellar embossing is that porous tantalum gets after annular knurl is processed.With respect to common coarse sprayed coating, the lamellar embossing that porous tantalum forms has that biocompatibility is high, bone is grown into the advantages such as the degree of depth is large, make the associativity of hip joint metal acetabular implant and human body bone stronger, improve the fixed effect of hip joint metal acetabular implant, realized the firm lasting use of hip joint metal acetabular implant.
Claims (2)
1. a hip joint metal acetabular implant, is characterized in that: described hip joint metal acetabular implant comprises a plurality of lamellar embossing (2) that metal acetabular hemisphere face (1) and porous tantalum form; Described lamellar embossing (2) is welded on described metal acetabular hemisphere face (1); Described lamellar embossing (2) is uniformly distributed along described metal acetabular hemisphere face (1).
