Summary of the invention
For the installation that overcomes the fibula in the accurate prosthesis of existing jawbone is owing to being hand operation and can not guarantee that installation accuracy causes the shortcoming that surgical effect cannot be definite, the invention provides a kind of moulding device of fibula auxiliary positioning for the accurate prosthesis of jawbone and preparation method thereof.
The technical solution used in the present invention is:
The manufacture method of the moulding device of fibula auxiliary positioning, comprises the following steps:
1. couple jaw defect patient carries out CT scan, then CT is imported to and in calculating, rebuilds maxillofacial bone bone model and fibula model.
2. on the maxillofacial bone bone model of rebuilding, clearly excise the cutting route of position and pathological changes jawbone, in computer, maxillofacial bone bone model is carried out to simulating cut along cutting route; And substitute the pathological changes jawbone model excising with fibula model, find out the substitute fibula segment model of length and the most adaptive maxillofacial bone bone of angle model otch.
3. the inner surface using the outer surface of fibula segment model as the moulding guide plate in location, carries out three-dimensional modeling to locating moulding guide plate, obtains the moulding guide plate model in location;
4. the moulding guide plate model in location is joined end to end by the connection angle of corresponding fibula segment model with spacer, obtain the model of the moulding device of fibula auxiliary positioning, and utilize rapid shaping technique to make the moulding device of fibula auxiliary positioning.
The moulding device of fibula auxiliary positioning that uses the manufacture method of the moulding device of above-mentioned fibula auxiliary positioning to make, locates moulding guide plate by multistage and connects and composes, and the inner surface of the moulding guide plate in location described in every section is fitted completely with corresponding fibula section outer surface; The adjacent moulding guide plate in described location press track that knuckle head and the tail form after fixing with set fibula the installation track on maxillofacial bone bone consistent, the described location free-ended end face of moulding guide plate is adapted to the laminating with jawbone otch.
The adjacent moulding guide plate in described location is fixed by arc spacer.
Beneficial effect of the present invention is embodied in: this apparatus structure is simple, easy to operate, use the moulding device of this fibula auxiliary positioning can make the fibula intercepting in the accurate prosthesis of jawbone to be accurately installed in jawbone according to the installation route in desirable operation plan, guarantee surgical effect, reduced operating difficulty and risk.
Brief description of the drawings

Detailed description of the invention
With reference to accompanying drawing, the manufacture method of the moulding device of fibula auxiliary positioning, comprises the following steps:
1. couple jaw defect patient carries out CT scan, then CT is imported to and in calculating, rebuilds maxillofacial bone bone model and fibula model.
2. on the maxillofacial bone bone model of rebuilding, clearly excise the cutting route of position and pathological changes jawbone, in computer, maxillofacial bone bone model is carried out to simulating cut along cutting route; And substitute the pathological changes jawbone model excising with fibula model, find out the substitute fibula segment model of length and the most adaptive maxillofacial bone bone of angle model otch.
3. the inner surface 11 using the outer surface of fibula segment model as the moulding guide plate 1 in location, carries out three-dimensional modeling to locating moulding guide plate 1, obtains moulding guide plate 1 model in location;
4. moulding guide plate 1 model in location is joined end to end by the connection angle of corresponding fibula segment model with spacer, obtain the model of the moulding device of fibula auxiliary positioning, and utilize rapid shaping technique to make the moulding device of fibula auxiliary positioning.
The moulding device of fibula auxiliary positioning that uses the manufacture method of the moulding device of above-mentioned fibula auxiliary positioning to make, it is characterized in that: locate moulding guide plate 1 by multistage and connect and compose, the inner surface 11 of the moulding guide plate 1 in location described in every section is fitted completely with corresponding fibula section outer surface; The moulding guide plate 1 in adjacent described location press track that knuckle head and the tail form after fixing with set fibula the installation track on maxillofacial bone bone consistent, the described location free-ended end face 12 of moulding guide plate 1 is adapted to the laminating with jawbone otch.
The moulding guide plate 1 in adjacent described location is fixing by arc spacer 2.
Before operation, jaw defect patient is carried out to CT scan, then CT is imported in calculating, utilize medical software mimics to rebuild maxillofacial bone bone model and fibula model; On the maxillofacial bone bone model of rebuilding, tumor is involved to scope to be judged, clearly excise the cutting route of position and pathological changes jawbone, in computer, maxillofacial bone bone model is carried out to simulating cut along cutting route, the threedimensional model of fibula is moved on to Jawbone Pathoses position and substitute original pathological changes jawbone, find out the fibula section of mating most by adjustment fibula modal position, angle, length, design desirable operation plan; In medical software geomagics, extract the outer surface of the fibula in the operation plan designing as the inner surface 11 of the moulding guide plate 1 of fibula auxiliary positioning, the moulding guide plate 1 of fibula auxiliary positioning is carried out to three-dimensional modeling, obtain moulding guide plate 1 model of fibula auxiliary positioning, and in rhinoceros software, these several moulding guide plate 1 use spacers of fibula auxiliary positioning are linked together, so just obtain the threedimensional model of the moulding device of fibula auxiliary positioning, and saved as STL form; Use rapid shaping technique, import to three-dimensional printer post-treatment and go out the required moulding device of fibula auxiliary positioning.
In the time of clinical operation, doctor is first transplanted to the patient's who has intercepted Fibula autograft the jawbone region of pathological changes, then by making the moulding guide plate 1 of fibula auxiliary positioning and fibula laminating go to adjust the installation site of fibula, make the angle of fibula and position meet the installation track in the operation plan designing; Use the same method successively and adjust next section of fibula, finally fix the fibula behind accurate location with molding reconstruction titanium plate device.
