Abstract
The invention discloses a designing and forming method for an anatomical bone plate of an individuation bone model. The designing and forming method includes the steps that 1, data is collected, wherein the affected side and the unaffected side of a patient are scanned through a CT machine, and a video file of the Dicom format is collected and introduced into medical three-dimensional reconstruction software for three-dimensional reconstruction; 2, the medical three-dimensional reconstruction software is used, and images are segmented through the data scanned by the CT machine, subjected to bone three-dimensional model reconstruction, subjected to substantialization in reverse engineering software and converted into a solid model formatted file; 3, CAD software is designed through a computer in an assisted mode, and according to the three-dimensional reconstruction model of bone, corresponding processing is carried out. By means of the designing and forming method for the anatomical bone plate of the individuation bone model, the individuation anatomical internal fixation steel plate with the quite-high bone matching rate can be rapidly customized according to different patients, different parts and different fracture characteristics, the internal fixation steel plate of the patient is completely individualized, and best fixing performance is developed.
Description
Technical field
The present invention relates to design and the forming method of the dissection type bone fracture plate of a kind of individuation skeleton model.
Background technology
Fracture internal fixaiion is to maintain fracture reduction and stable technology with metal or biomaterial by bone surgery after the reduction of the fracture.Digital technology and the development of Medical Imaging Technology, provide technical support to the enforcement in the preoperative planning of bone surgery scheme and art.Accurate personalized preoperative plan can reduce interior fixation implant required during the subjective conjecture of experiential therapy, the success rate on increase operation technique, and preoperative plan also can make patient make arrangements for surgery in advance.How in virtual environment, to obtain the internal fixation device model optimizing design, be the key link realizing accurate orthopaedics virtual operation.The method of existing interior fixation bone fracture plate digital modeling mainly includes that computer software assists forward three-dimensional modeling and reverse software based on 3-D scanning modeling.Three-dimensional modeling based on CAD software, can model accurately according to the geometric properties of entity, and its premise is to possess original size data or the measurement of engineering sketch of entity, and design is time-consuming long, is used for the modeling of rule steel plate.This forward design can solve part Data Source problem by entity measuring, but the blade plate anatomical compatibility degree be often limited to the complexity of orthopedic fixation device tool surface texture and the height individuation difference of bone surface curvature, therefore designing is poor, it is difficult to play optimal fixed performance；Reverse software based on 3-D scanning modeling mainly uses the method for surface point cloud acquisition, its precision is easily affected by surface color, the roughness of entity, often need to coat " contrast enhancement agents " on tested blade plate surface or do process of spraying paint, even so, the model reconstructed still suffers from distortion.Due to individual variation, existing normal bone plate is difficult to the design of individuation height anatomical compatibility, make art light plate moulding bad, or implant can not mate the instrument of skeleton anatomical structure of suffering limb completely, some patients is caused to occur union of fracture to postpone, malunion or bone does not connect, even implant fracture, take out difficulty etc. problem.
Therefore, not enough for prior art, the present invention will provide design and the forming method of a kind of personalized dissection type bone fracture plate, can go out to be suitable for fixation bone fracture plate in the high coupling anatomical form of different patient, different parts and different fracture Morphological Characteristics by fast custom, make the complete individuation of the interior fixation bone fracture plate of patient, and can direction, self-defined nail road to realize the Individual design of preoperative planning and mechanical property, thus overcome tradition blade plate deficiency.
Summary of the invention
The present invention design of the dissection type bone fracture plate of a kind of individuation skeleton model and forming method are provided it can be avoided that tradition blade plate in design, manufacture and the weak point of application aspect, design and the manufacture molding of personalized steel plate are provided, the construction method of this personalization steel plate can go out according to different patients, different parts, the high individuation anatomical form internal fixation steel plate of skeleton matching degree of different Bone fracture characteristics by fast custom, makes the complete individuation of internal fixation steel plate of patient and plays optimal fixed performance.
For solving the problems referred to above, the present invention adopts the following technical scheme that
The design of the dissection type bone fracture plate of a kind of individuation skeleton model and forming method, comprise the steps:
1) data acquisition: using CT machine that patient carries out Ipsilateral and the scanning of both sides, strong side, gathering image file is Dicom formatted file, imports medical 3 D reconstruction software and carries out three-dimensional reconstruction；
2) use medical 3 D reconstruction software, according to CT machine scan data, image is split, and carry out bone reconstructing three-dimensional model, hypostazation be converted into physical model formatted file in reverse engineering software；
3) computer aided design cad software is used, Three-dimension Reconstruction Model according to bone, screw rotor and pruning lamellar body function accurate Drawing is used to go out the Irregular Boundary Surface of steel plate lay down location skeleton, design the steel plate in strong side with bone photo laminating, Ipsilateral steel plate main body is obtained by image feature, in combination with Ipsilateral GUSUIPIAN size, position and fracture line length, design spacing and the distribution of screw hole, preserve file；
4) steel plate STL form model is imported 3D print system, carry out metal 3D printing, then carry out afterbody tapering curved surface polishing processed.
As preferably, described step 3) in accurate Drawing be according to the contour line that extracts in reverse engineering software of bone threedimensional model rebuild, use screw rotor and pruning lamellar body function accurate Drawing in CAD software to go out the Irregular Boundary Surface of steel plate lay down location skeleton, thus design the steel plate in strong side with bone photo laminating.
As preferably, described step 3) in be the symmetry according to skeleton to customize steel plate model carrying out mirror image processing, the strong side obtained is customized steel plate model and carries out mirror image processing, obtain side seam is customized steel plate model.
The invention have the benefit that the motility substantially increasing blade plate internal fixation treatment, the accurate treatment of personalization can be realized；Individuation dissection type bone fracture plate have employed patient's both limbs CT/MRI fault image data basis as three-dimensional reconstruction in design, and Data Source reliably and easily obtains, and can implement at basic medical unit；The reverse Engineering Technology modeling used, realize quickly manufacturing and designing, current operative doctor can be changed and visually carry out the present situation of the moulding steel plate of pre-bending with experience, this can reduce the fatigue strength of blade plate, increases the risk of implant fracture, the step for of the most not only saving, and reduce operation wound, shorten operating time, reduce the complication such as malunion of fracture, bone does not connect and occur, in complying fully with modern orthopaedics, fix the theory of Wicresoft BO；Personalized customized steel plate, overcomes traditional operation steel plate because the bone radian that cannot meet different patient differs, and fracture line is different, and the steel nail caused and Kirschner wire cannot accurate estimate amount, surgery cost is high.
