Abstract
The utility model discloses a phalange implant. The phalange implant comprises a matrix I1, a matrix II2, a hinging piece 3, a cone I4 and a cone II5, wherein the matrix I1 is provided with a fixed casing pipe I6; the cone I4 is inserted into the fixed casing pipe I6; the matrix II2 is provided with a fixed casing pipe II7; the cone II5 is inserted into the fixed casing pipe II7; the cone I4 and the cone II5 are hinged through the hinging piece 3; II type anodic oxidation coatings are arranged on the surfaces of the cone I4, the cone II5, the fixed casing pipe I6 and the fixed casing pipe II7; a porous tantalum coating is arranged on the hinging piece 3. The phalange implant with the structure has excellent stationarity and flexible moveability and has strong biocompatibility, so that the implant and human bone cells are agglomerated completely and the phalange implant is convenient and flexible to use.
Description
Technical field
This utility model relates to a kind of phalanges implant, relates in particular to that a kind of stationarity and mobility have concurrently, biocompatibility is high, use phalanges implant flexibly.
Background technology
In implant surgery, titanium or titanium alloy are implant material commonly used.This be due to, with respect to steel alloy, titanium or titanium alloy density are less, also possess simultaneously certain biocompatibility, allow implant and osteocyte coalescent.
But, in the implant surgery at a lot of positions, only need certain of implant or a few place coalescent with the generation of human bone cell, if occur coalescent at other positions in addition, can damage on the contrary the loading capability that is subjected to of whole implant, cause that maintenance is unstable or loosening, even can cause the implant fracture.In general, coalescent position implant when best physiological loads place is subjected to loading capability the strongest, distributes the most reasonable.
Therefore, should promote that at best physiological loads place implant and osteocyte are coalescent, prevent that again other positions from forming coalescent, this is a great problem of the position implant therapies such as current femur, Patella, phalanges.
II type anodized coating is that silicon oxide is introduced to the conversion coating near material surface, forms an ingredient of material monolithic.II type anodized coating can hinder the soma growth, can improve again the durability of material monolithic, can be used for the surface of the body implants such as femur.
The utility model content
In view of the foregoing defects the prior art has, this utility model aims to provide a kind of stationarity and the mobility has concurrently, biocompatibility is high, use phalanges implant flexibly.
To achieve these goals, this utility model by the following technical solutions: the phalanges implant comprises matrix I, matrix II, articulated elements, cone I and cone II; On described matrix I, with the fixed sleeving I, described cone I is plugged in described fixed sleeving I; On described matrix II, with the fixed sleeving II, described cone II is plugged in described fixed sleeving II; Described cone I and described cone II are hinged by described articulated elements; Described cone I, cone II, fixed sleeving I and fixed sleeving II surface are provided with II type anodized coating; Described articulated elements is provided with the porous tantalum coating.
As the improvement to the technical program, described matrix I and matrix II surface are provided with rough coatings.
Compared with the prior art, this utility model has been owing to having adopted technique scheme, has good stationarity and mobility flexibly concurrently, has very strong biocompatibility, make between implant and human bone cell fully coalescently, make the phalanges implant more convenient to use flexibly.
The accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
In figure: 1 matrix I, 2 matrix II, 3 articulated elements, 4 cone I, 5 cone II, 6 fixed sleeving I, 7 fixed sleeving II.
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 phalanges implant, as shown in Figure 1, the phalanges implant comprises matrix I 1, matrix II 2, articulated elements 3, cone I 4 and cone II 5; On described matrix I 1, with fixed sleeving I 6, described cone I 4 is plugged in described fixed sleeving I 6; On described matrix II 2, with fixed sleeving II 7, described cone II 5 is plugged in described fixed sleeving II 7; Described cone I 4 and described cone II 5 are hinged by described articulated elements 3; Described cone I 4, cone II 5, fixed sleeving I 6 and fixed sleeving II 7 surfaces are provided with II type anodized coating; Described articulated elements 3 is provided with the porous tantalum coating.
In order to promote the merging of matrix and corresponding phalanges, described matrix I 1 and matrix II 2 surfaces are provided with rough coatings.
The main body of matrix, articulated elements and cone adopts titanium alloy to make, to guarantee enough mechanical strengths.After implantation, matrix merges with corresponding phalanges.The articulated elements position is best physiological loads place, the porous tantalum coating has very high biocompatibility, can start very soon bone cell growth, promotes that implant and osteocyte are coalescent, make implant in this position, can realize well being connected and maintenance with body bone tissue, guarantee its stationarity.
The grafting of fixed sleeving and cone makes matrix and cone can realize relative motion, has guaranteed the mobility of implant, makes implant more convenient to use flexibly.II type anodized coating has cell growth inhibiting, prevents the effect that implant and human bone cell knot are formed, and has guaranteed well carrying out smoothly of relative motion, makes postoperative finger energy flexible motion.
