And the interior positive camber of described implant all has respectively ± radian of 0 °～± 90 °.
And the interior positive camber of described implant is sphere curved surface, oval curved surface, square or rectangular curved surface.
And the radius of described implant positive camber is 2～300 millimeters, the distance of interior positive camber is 1～20 millimeter.
And the thickness of the eaves body of described implant is 0～5 millimeter, eaves body angular range is 0～180 °.
And the positive camber of described implant is Two-way Network shelf structure, support body height is 0.2～2 millimeter, and width is 0.3-10mm, and unidirectional rack quantity is 2～10.
And, on the eaves body of described implant, being shaped with symmetrically 3～12 diameters and being the fixing hole of 0.2～5 millimeter, pitch-row is from 0.5～5 millimeter, cap shell edge.
And the fixing hole of described implant and positive camber angle are 0-90 °.
It is pre-formed that described implant adopts the bone renovating material of plastic type to carry out, the particularly bone renovating material of absorbable and degradable (patent No.: ZL01129699.2).
Compared with prior art, the beneficial effects of the utility model are:
1, this implant is owing to having cap shelly and eaves body, not only can make it stably be fixed on patient's defect of skull place, simultaneously than " a kind of skull/jawbone defect reparation filler plug " (application number: 201320180732.4) more there is bionical radian, the more identical defect of skull of eaves body design edge, doctor is easy to use, thereby can save the time of operation, reduce patient suffering and medical expense.
2, this implant structure is relatively simple, can be according to the damaged part of different patient crowds, and manufacturing enterprise can carry out prefabricated, in doctor's operation, can select different model, and product service efficiency is provided; Or can adopt the damaged place scanning of 3-D scanning technology to patient, collect data, then use computer software modeling, prepare the implant more mating with patient.
3. the positive camber of this implant has added Two-way Network shelf structure, changes owing to adapting to different pressures with implant; To the prefabricated implant of absorbable material, rack can be material degradation headspace is provided simultaneously;
4, this implant, owing to being shaped with fixing hole on eaves body, can adopt the consistent cylinder of raw material to clog, and is convenient to the fixing of large area defect of skull.
