The specific embodiment
(Fig. 1-Fig. 6) the utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this utility model stereo grid shaped bone filler structural representation.As shown in Figure 1, stereo grid shaped bone filler comprises three-dimensional structure, along all surface of the described three-dimensional structure cellular cavity that distributing.Described cellular cavity is the grid arrangement of rule.The grid 2 of described rule is the quadrate array that is made up by cylindricality limit 1, obviously can also be rectangular array, triangular array, rhombus array or hexagonal array, also can be other irregular polygon shapes.The grid of rule also can be circular array or oval-shaped array.
Three-dimensional structure is Titanium goods or titanium alloy product.Certainly, three-dimensional structure can adopt other the biological structure material that meets the medical science standard.
Fig. 2 is the unit grid structural representation.As shown in Figure 2, the cylindricality limit is a cylinder, and the diameter of phi of cylinder is 20 μ m～2mm; The grid length of side a of each grid is 50 μ m～5mm.Obviously, the polygon cylinder can be adopted in the cylindricality limit.When unit grid is non-rectangle, can describe with area, for example, the area of each grid is 2000 μ m
2～30mm

Though Fig. 2 expression is square, obviously can also be rectangle, triangle, rhombus or hexagon, also can be other irregular polygon shapes etc.The cylindricality limit that Fig. 2 represents is a cylinder, but obviously can also be cylindroid, square column or polygon post etc.
Three-dimensional structure forms by laser selective sintering process, atomic layer deposition method or electron beam melting manufactured.
Electron beam melting Rapid Manufacturing Technology and equipment can be selected the EBMA2 type of Sweden ARCAMAB company for use.
Through overtesting, for example precision-investment casting of processing method early, digital manufacturing such as digital control processing field processing method is owing to be subjected to the manufacturing that the restriction of processing technique own can not have been satisfied three dimensional network structure like that.Therefore, the processing method of suggestion employing has: advanced manufacture methods such as laser selective sintering process, atomic layer deposition method, electron beam melting method.
Briefly introduce each advanced manufacture method below respectively.
Atomic layer deposition method: be a kind of can be with material with the monatomic form membrane method that is plated in substrate surface in layer.Ald and common chemical deposition have similarity.But in atomic layer deposition process, the chemical reaction of new one deck atomic film is directly to be associated with one deck before, and this mode makes each reaction only deposit one deck atom.
Electron beam melting law technology: refer at deposite metal, electron beam constituency powder forming.Its principle is that energy density is high after utilizing electron beam to focus on, with high velocity shock to the minimum area of surface of the work, in the extremely short time (part second), its energy major part changes heat energy into, make the workpiece material that is impacted part reach high temperature more than several thousand degrees centigrade, cause the local melting of material or the performance of gasification.The electron beam melting law technology comprises following work flow: 1. with 3D CAD software design part: the electronic 3-D model of design elements (mathematical model, cad model) at first, press the certain thickness layering according to technological requirement, original three-dimensional CAD model is become a series of synusia, according to the profile information of each synusia, the input machined parameters generates numerical control code automatically.2. with electron beam melting technology finished parts: the principle of utilizing metal dust under beam bombardment, to melt, fusing is shaped in the electron beam constituency to make it, sprawl powder and compacting on powder plane, shop, electron beam under the control of computer according to the information of cross section profile selectively be melted to part all fusing finish, remove unnecessary powder and obtain required three-dimensional objects.3. obtain metal parts.
Laser selective sintering process: be that laser beam by accurate guiding makes material powder sintering or fusion after coagulation form three-dimensional prototype or product.Laser selective sintering process work flow comprises: the CAD 3D three-dimensional contouring part of modeling at first on computers, or the 3D solid graphic file that obtains by reverse-engineering.Convert thereof into the stl file form.Then with discrete (section) software from disperse out the orderly lamella of a series of given thickness of stl file.Perhaps directly cut into slices from cad file.These discrete lamellas are accumulated in order and are still designed part physical form.At last, above-mentioned discrete (section) data are delivered in the make-up machine and go, the scanning device in the make-up machine successively scans sintering under the control of computerized information.
As follows about application note of the present utility model:
The cuboid that at first designs a grid composition is a stereo grid shaped bone filler to be cut, and for example shown in Figure 1, the length and width height can be within 10mm～500mm scope.Be mainly used in the reparation of cranio-maxillofacial, bone of body, bones of upper limb, Lower limb bone etc.Utilize the surface configuration at required reparation position, for example: Fig. 3 is a mandibular bone free form surface shape, and Fig. 4 is the stereo grid shaped bone filler that cuts the alternative mandibular bone that forms according to Fig. 3.Fig. 5 is a cervical vertebra free form surface shape, and Fig. 6 is the stereo grid shaped bone filler that cuts the alternative cervical vertebra that forms according to Fig. 5.That is to say, be stereo grid shaped bone filler by the cutting network structure, will obtain being fit to the net of required reparation position shape, and implant into body plays the effect of reparation with regard to the growth of bootable human body soft tissue.
Should be pointed out that the above specific embodiment can make those skilled in the art more fully understand the invention, but do not limit the present invention in any way creation.Therefore, although this description has been described in detail the invention with reference to drawings and Examples,, it will be appreciated by those skilled in the art that still and can make amendment or be equal to replacement the invention; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all is encompassed in the middle of the protection domain of the invention patent.
