Abstract
The utility model discloses an artificial hip joint double acting head. The artificial hip joint double acting head comprises a double acting cup lining 1, a spherical head cavity 2 and a double acting spherical cup 5, wherein the double acting cup lining 1 is installed in the double acting spherical cup 5, and the spherical head cavity 2 is formed in the double acting cup lining 1; a snap ring 3 is arranged at the top end inside the double acting cup lining 1 and on the top of the spherical head cavity 2; an annular groove 4 is formed in the outer side surface of the double acting cup lining 1; a cutting groove 6 is formed in the snap ring 3; a multihole tantalum layer 8 is arranged on the outer side surface of the double acting spherical cup 5. The artificial hip joint double acting head of the structure does not easily loosen and disengage and is more convenient to use, and biocompatibility is improved.
Description
Technical field
This utility model relates to a kind of double motion head of artificial hip joint, relates in particular to a kind of loose or dislocation, biocompatibility double motion head of artificial hip joint high, easy to use of being difficult for.
Background technology
The femoral hip prosthesis implantation is the treatment operation a kind of commonly used of current treatment femur head necrosis, and its critical component is femoral hip prosthesis head implant.Double motion head is one of building block of femoral hip prosthesis head implant.Existing double motion head generally consists of spherical shell and liner, and during use, two moving ball glass holders are on the bulb of joint handle, and bulb easily occurs loosening and comes off, and puts to no little inconvenience to the use of double motion head.
The utility model content
In view of the foregoing defects the prior art has, this utility model aims to provide a kind of loose or dislocation, biocompatibility double motion head of artificial hip joint high, easy to use of being difficult for.
To achieve these goals, this utility model by the following technical solutions: double motion head of artificial hip joint comprises two moving cup linings, bulb chamber and two moving ball cup; Described two moving ball cup is in-built has described two moving cup to serve as a contrast, and in described two moving cup linings, is provided with described bulb chamber; Be provided with snap ring in described two moving cup lining inner tip, described bulb chamber on top; Described two moving cup lining outer surface is provided with cannelure; Be provided with grooving on described snap ring; Described two moving ball cup outer surface is provided with the porous tantalum layer.
As the improvement to the technical program, on described snap ring, the tip position of close described grooving is provided with to hold and gets hole.
Compared with the prior art, this utility model, owing to having adopted technique scheme, makes double motion head of artificial hip joint be difficult for occurring loosening and come off, and has improved the biocompatibility of double motion head of artificial hip joint, makes double motion head of artificial hip joint more convenient to use.
The accompanying drawing explanation
The structural representation that Fig. 1 is this utility model embodiment.
The structural representation that Fig. 2 is this utility model snap ring.
In figure: 1 pair of moving cup lining, 2 bulb chambeies, 3 snap rings, 4 cannelures, 5 pairs of moving ball cups, 6 groovings, 7 are held and are got hole, 8 porous tantalum layers.
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 double motion head of artificial hip joint, as depicted in figs. 1 and 2, double motion head of artificial hip joint comprises two moving cup linings 1, bulb chamber 2 and two moving ball cup 5; Described two moving ball cup 5 is in-built has described two moving cup to serve as a contrast 1, in described two moving cup linings 1, is provided with described bulb chamber 2; Be provided with snap ring 3 in described two moving cup lining 1 inner tip, described bulb chamber on 2 tops; Described two moving cup lining 1 outer surface is provided with cannelure 4; Be provided with grooving 6 on described snap ring 3; Described two moving ball cup 5 outer surfaces are provided with porous tantalum layer 8.
For the ease of the clamping snap ring, on described snap ring 3, the tip position of close described grooving 6 is provided with to hold and gets hole 7.
The bulb chamber is provided with snap ring on top, thereby has played the effect that prevents the bulb loose or dislocation, makes the hip joint double motion head more convenient to use.
The porous tantalum layer can be brought into play the advantage of its good biocompatibility, promotes recovery and result of use after double motion head of artificial hip joint is implanted.
The setting of cannelure can be installed in two moving ball cups two moving cup linings easily.The setting of grooving makes the flexible of snap ring and amplifies very convenient.
