Abstract
The utility model discloses a hip socket outer cup implant for a hip joint, which comprises a basal outer cup 1 and positioning and fixing thorns 2, wherein the external surface of the basal outer cup 1 is a spherical surface; the positioning and fixing thorns 2 are distributed on the external surface of the basal outer cup 1, and are integrally formed with the basal outer cup 1; hemispheric concave parts 3 are formed in the external surface of the basal outer cup 1; porous tantalum is filled in the hemispheric concave parts 3. Through the adoption of the structure, the positioning effect of the hip socket outer cup implant is enhanced, the attachment strength of the hip socket outer cup implant is improved, the biocompatibility of the hip socket outer cup implant is promoted, and the operation success rate can be relatively high.
Description
Technical field
This utility model relates to a kind of hip joint acetabular outer cup implant, relates in particular to that a kind of good positioning effect, tightness are high, good biocompatibility, hip joint acetabular outer cup implant that success rate of operation is high.
Background technology
When being human hip generation pathological changes, passes through hip joint acetabular outer cup implant the replacement prosthesis of orthopaedics replacement operation implant into body hip joint.Its effect is to recover to a certain extent the physiological function of hip joint, and alleviating pain improves motion function, improves the quality of living.
There are two large defects in existing hip joint acetabular outer cup implant: the one, and locating effect is bad, and after implanting, tightness is not high; The 2nd, little with the human body contact area, easily produce and get loose, success rate of operation is not high, patient's physiological load weight.
The utility model content
In view of the foregoing defects the prior art has, this utility model aim to provide that a kind of good positioning effect, tightness are high, good biocompatibility, hip joint acetabular outer cup implant that success rate of operation is high.
To achieve these goals, this utility model by the following technical solutions: hip joint acetabular outer cup implant comprises the fixing thorn of basic outer cup and location; Described basic outer cup outer surface is spherical; The fixing thorn in described location is distributed in described basic outer cup outer surface, and the fixing thorn in described location is formed in one with described basic outer cup; Described basic outer cup outer surface is provided with hemispheric recess, in the female section, is filled with porous tantalum.
As the improvement to the technical program, the fixing thorn in described location and the female section quantity are greater than one.
As the improvement to the technical program, the fixing thorn in described location is sharp cone distal.
Compared with the prior art, this utility model, owing to having adopted technique scheme, has been strengthened the locating effect of hip joint acetabular outer cup implant, has improved the tightness of hip joint acetabular outer cup implant, promoted the biocompatibility of hip joint acetabular outer cup implant, made success rate of operation higher.
The accompanying drawing explanation
The structural representation that Fig. 1 is this utility model embodiment.
In figure: 1 basic outer cup, the 2 fixing thorns in location, 3 recess.
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 acetabular outer cup implant, as shown in Figure 1, hip joint acetabular outer cup implant comprises the fixing thorn 2 of basic outer cup 1 and location; Described basic outer cup 1 outer surface is spherical; The fixing thorn 2 in described location is distributed in described basic outer cup 1 outer surface, and the fixing thorn 2 in described location is formed in one with described basic outer cup 1; Described basic outer cup 1 outer surface is provided with hemispheric recess 3, in the female section 3, is filled with porous tantalum.
Preferably, the fixing thorn 2 in described location and the female section 3 quantity are greater than one.
Preferably, the fixing thorn 2 in described location is sharp cone distal.
The effect of locating fixing thorn is to play location and fixing effect, makes acetabular outer cup implant rear locating effect better, and tightness is stronger.The porous tantalum of the high-biocompatibility that basis outer cup outer surface recess is filled can start rapidly bone tissue growth, promotes that sclerotin enters, and can further strengthen locating effect, prevents from getting loose, and improves success rate of operation.
