Finding desirable artificial bone, to repair the clinical Cranial defect caused because of a variety of causes be the very active problem of field of orthopaedics research always.In order to filling bone defect chamber or the material in space between bone implanting part and bone bed, its effect accelerates bone defect healing or bone implanting part is fixed.Existing Cranial defect filler particles structure is single, can not be suitable for different Cranial defect situations.
Summary of the invention
The object of this invention is to provide a kind of 3D and print Cranial defect packing material, be applicable to the Cranial defect situation of different parts.
For achieving the above object, the technical solution adopted in the present invention is: described packing material comprises granule and the flexible net for enwrapped granule body, the surface of flexible net is provided with mesh, the aperture of mesh is less than the size of granule, granule supports summit support by 4,6 or 8 and forms, and the surface of granule is evenly equipped with micropore.
Preferably, described granule and flexible net all once print manufacture by 3D printing technique and form.
Preferably, the aperture of described micropore is reduced to internal direction gradually by the surface of granule, and the cross section of described micropore is bone trabecula shape.
Preferably, granule is mallet body, and described mallet body comprises the limit ball being in inner astrosphere and being distributed in astrosphere surrounding, and the quantity of limit ball is 4,6 or 8, each limit ball is connected with astrosphere by a column, and the surface of astrosphere, limit ball and column is evenly equipped with micropore.
Preferably, the diameter of described column is reduced to astrosphere direction gradually by limit ball, and column is round table-like.
Preferably, every root column length is equal.
Preferably, column is cylindric, and the diameter of limit ball and the diameter of column are than being 1.3-2:1.
After adopting technique scheme, the present invention has following good effect:
(1) granule in the present invention is for solving the filling problem of Cranial defect in bone surgery, doctor can according to the practical situation of sufferer, prune flexible net structure, to cover the scope of Cranial defect, enwrapped granule body prevents it from leaking better, preventing from not being shed to by force in patient body because combining the generation causing complications, playing and strengthening the effect that the granule initial stage is fixed and the effect strengthening Bone Ingrowth;
(2) granule in the present invention can be mallet body or regular polygon, during for mallet body, can mutually embed and clamp between two mallet bodies, coincide, play the effect of filling with the geometric space shape of defective bone bed; After Cranial defect position is fully filled, be wrapped in filling block outside by flexible net, and in web-like edge screw hole place drivescrew, the effect that the initial stage that strengthens is fixing, avoids particle detachment;
(3) micropore on granule surface can strengthen frictional force, makes mutually to be fitted together between two granules and promote Bone Ingrowth, raising stability.
