Abstract
The invention discloses the cellular bone prosthesis stereochemical structure of a species and its application, the structure connects the stereochemical structure for forming repetition by some clava ends, and each its spatial form of stereochemical structure for repeating is made up of 2 pyritohedrons and 6 tetrakaidecahedrons.Stereochemical structure of the invention is generated by 3D printing clava, and its mechanical property is strong, and the space that abundance is remained between clava supplies bone growth, blood vessel is passed through, and can be used to produce any bone prosthesis for carrying out limb salvage treatment using the structure.
Description
Technical field
The present invention relates to material engineering and 3D printing field, the three-dimensional knot of the cellular bone prosthesis of a species is related in particular to
Structure and its application.
Background technology
The structures such as XYZ orthogonal formulas, radial, bionic type are used existing bone-imitation tissue supporting structure more.Wherein, XYZ formulas branch
Frame structure type is the simplest, and mechanical property is also more to be received by medical personnel, therefore, XYZ structures are the most commonly used.But the structure shape
Formula is relatively simple, is differed farther out with true skeletal structure, is unfavorable for bone tissue growth in the bracket, and mechanical property is compared with it
His several structures are poor.Similarly, spoke structure is also related farther out to true bone microstructure, is unfavorable for the life of bone tissue
It is long.In addition, bionic type although to design structure and true bone close, it is impossible to control its porosity.The hole of supporting structure
Rate is to evaluate a kind of important indicator of supporting structure.
The content of the invention
Goal of the invention：Possess outstanding mechanical property it is an object of the invention to provide one kind and provide sufficient clearance for bone group
The cellular bone prosthesis stereochemical structure of class of growth is knitted, bone is being prepared it is a still further object of the present invention to provide the stereochemical structure
Application on prosthese.
Technical scheme：In order to realize foregoing invention purpose, the cellular bone prosthesis stereochemical structure of a species of the invention, by
Some clava ends connect the stereochemical structure to form repetition, and each stereochemical structure its spatial form for repeating is by 2 five jiaos
Dodecahedron and 6 tetrakaidecahedron compositions.
Any one summit is connected by three or four clavas.
The pyritohedron is made up of 12 non-equilateral pentagons of identical.
The tetrakaidecahedron contains 2 hexagons and 10 pentagons, and 2 hexagons are located at opposite face and are parallel to each other.
The non-equilateral pentagon contains a side a long and four identical short side b, the length relation of side a long and short side b
ForThe hexagon of the tetrakaidecahedron includes two parallel isometric side c long, and four isometric
Short side d, the pentagon of the tetrakaidecahedron includes two classes：One class contain side c long and, it is another kind of to contain short side d.
The side c long of 2 hexagons of the tetrakaidecahedron is mutually perpendicular to.
The tetrakaidecahedron has 32 sides, wherein 4 it is long while c length with it is long while a it is identical, 16 side lengths are12 the length of side is4 side length is
Stereochemical structure of the invention is generated by 3D printing clava, and its mechanical property is strong, is remained between clava and filled
The space of foot supplies bone growth, blood vessel is passed through, and can be used to producing any bone prosthesis using the structure is used for
Carry out limb salvage treatment.

Specific embodiment
The present invention is further described with reference to specific embodiment.
As shown in Figure 1 to 11, the cellular bone prosthesis stereochemical structure of a species, is connected by some clava ends and is formed
The stereochemical structure for repeating, each stereochemical structure its spatial form for repeating is by 2 pyritohedrons and 6 tetrakaidecahedron groups
Into.
Any one summit is connected by three or four clavas.The pyritohedron is non-etc. by 12 identicals
Side pentagon composition.
The tetrakaidecahedron contains 2 hexagons and 10 pentagons, and 2 hexagons are located at opposite face and are parallel to each other.
The non-equilateral pentagon contains a side a long and four identical short side b, and the length relation of side a long and short side b isThe hexagon of the tetrakaidecahedron includes two parallel isometric side c long, and four isometric short
Side d, the pentagon of the tetrakaidecahedron includes two classes：One class contain side c long and, it is another kind of to contain short side d.
The side c long of 2 hexagons of the tetrakaidecahedron is mutually perpendicular to.The tetrakaidecahedron has 32 sides, wherein 4 sides long
C length is identical with side a long, and 16 side lengths are12 the length of side is4 side length is
As shown in figure 12, when above-mentioned stereochemical structure prepares bone prosthesis for production, using 3D printing technique according to patient
The bone situation of blocking carries out regeneration printing, and the product is used for humerus amputation, and the two ends of honeycomb are provided with for inserting ossis
Shaft is fixed.Bone plate can be also set up on the basis of the structure.
The above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
