Description of the Invention: [Technical Field of the Invention] The present invention relates to a method for producing a bone plate and a method for producing a bone plate for special surgery. Tan Gu Yan Noodles [formerly known as the street] Gu Yan face surgery is extremely important for surgery. Fan Yiyi, := congenital shape-cutting, acquired external; ('If the bone main = tumor resection caused by facial defects for shaping Surgery. — Factory Flyer=When performing craniofacial reconstruction surgery, 'depend on the two-dimensional electric heart:: Or establish a three-dimensional model of the patient for preoperative planning, and then combine the professional experience and the on-site response to directly determine the position of the bone plate implant. And the second corner is built with a crippled face that is incomplete or deformed. The method of making the plate is mainly the production of the injection molding, which can only be used to make the bone plate of the shape, size and specification of the county. According to the space position of the doctor's hand 11 Tian 4 according to the '% of the patient's craniofacial damage, the pre-standard bone plate is hand-turned into a four-degree, direction and configuration for the = concave concave plate pair _ The damage is fixed or repaired by the bridge, and 'because the overall structure, thickness, shape and space of the bones are more complicated' and the department consists of upper and lower wealth, involving occlusion and entry. _ and _ shape and other issues, both beautiful Functional weight: The conventional bone plate making method can only produce a standardized bone plate, and the method of fine cancer meets the shape of the damaged part of the Gu Yan part, resulting in the inconvenience of use 201236638; and in the course of surgery The standardized bone plate allows the physician to manually shape and shape according to the rule of thumb, and uses the bone plate to randomly locate the damaged portion of the Gu Yan part, not only the size and shape of the damaged portion of the bone plate and the craniofacial portion are not corresponding. The positioning position of the bone plate is also difficult to accurately match the bone environment of the damaged portion of the craniofacial region, which seriously affects the accuracy and precision of the reconstruction of the craniofacial reconstruction. Due to the influence of the aforementioned problems, the reconstruction of the craniofacial reconstruction The prognosis time is often poor, and often patients who are unsuccessful in the operation cannot be properly occluded, chewed, or even hindered the arrangement of the gums, resulting in poor healing of the affected part, affecting the patient's appearance and facial movements. Most patients can only borrow. The long-term and repeated lip and nose surgery has been able to restore better lip and palate function. Another common method of making bone plates is the United States. As described in Patent No. 7,6,3,192, it uses computer tomography and a solid model to create single or several stereoscopic image data, and defines the X, Y, and Z planes of each stereo image to combine Stereoscopic image data, and then obtain a three-dimensional spatial three-dimensional model of the intact affected part and the bone plate, and then the three-dimensional image is designed to compare the bone plate of the affected part to perform bone plate production. However, the above mentioned patents mention The method of making the bone plate only designs the inclination of the adhesion between the bone plate and the silk surface of the affected part, and does not consider the mechanics of the affected part and the bone plate, the need for the shape and the occlusion function of the face of the skull, therefore, It can only make the shape of the body, the thickness of the sentence and the force of the limbs of the limbs. Because of the structure of the Gu Yan bone and the stress of each part is more complex, it is easy to produce complex fractures of 201236638, therefore, the use of bone plate production methods It is not necessary to consider the relationship between the affected part and the bone plate. The complex space of the craniofacial area should be reconstructed in the face of the face. It is impossible to enhance the face weight due to the energy. The accuracy and accuracy of the construction, the appearance considerations, or the function of the upper and lower bones. SUMMARY OF THE INVENTION The main purpose of the mechanical bearing plate of the affected part of the face is the mechanical bearing of the affected part of the cranial face, the design of the == allows the bone plate to withstand the accuracy. Accuracy of reconstructive surgery from the so-called craniofacial bone The second objective of the present invention is to make a post-operative condition in a group of degrees that relies on the individual's individual to make a postoperative condition. For example, in order to achieve the aforementioned invention, the technical means used in the present invention include the method of making a bone plate: the method of making a bone plate includes: the image acquisition step takes a stereoscopic image of the patient; Image reconstruction step _—image processing y constructs the original stereo image image 4, (4) obtains a heavy image, and the image is in the system of the Wei pen corresponding to the mechanics of a craniofacial (10); After the image processing, reading the stereoscopic image of the county is like reconstructing the stereoscopic f-plane _, and defining the difference between the image and the image as a defect portion; _ data extraction step in the image processing system, the defect of alcohol The mechanical data of the part of the cranial face corresponding to the Ministry' is defined on the reconstructed stereo image - to compensate for the mechanical compensation zone of the mechanical data subjected to the lack of (4); a model design step 201236638 based on the surface of the mechanical compensation zone The shape design is a bone plate karyotype having a thickness, and the bone plate making step produces a bone plate conforming to the bone plate model according to the bone plate model. BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features, and advantages of the present invention will become more apparent from the aspects of the invention. The "mechanical data" described above is used to determine the strength and directionality of the two forces subjected to the occlusion. For example, the strength and directionality of the force in the occlusion process are called. Further, it is difficult to make a bone plate making method of a slightly better embodiment. The image processing system includes at least a central processing =: the central processing unit corresponds to a number of strokes corresponding to the mechanical data that is attached to the data - the parts of the cranial face are as follows.力学 The mechanics of each point in the bite. 1 The mechanical data includes all ethnic groups “such as race, age or sex = ==: bearing stress, actuation, and other needs of each family.” The design of the board is preferred. For patients with natural craniofacial defects, έ τ is for various congenital or posterior facial bone plates. - Test 1 for mechanical preparation of the customized cranial bone.

The original stereoscopic image has a portion 1 of the lesion or defect of the patient's face, as shown in Fig. 3. ▲ μ refers to the third to fourth _, the image reconstruction step S2 uses the original stereoscopic image to perform the image reconstruction, and the mechanical data received by each part. The more detailed cranial surface of the skull and the 3rd image of the original stereoscopic image contain the cause of each *there is a cranial face reading of the various affected parts, and each of the two must use the image processing system to image the original two Reconstruction is performed to obtain a heavy shirt image, and the patient may be read as in Reading 34. For example, the facial fractures of the patient's lower bones and the complexity of the situation, the situation must be handled by the image (site 1), and there are cases where the shadows of the two cracks and the threshold selection range 201236638 The image is edited to obtain the reconstructed stereoscopic image of the patient; or the reconstructed stereoscopic image can be obtained by mirror image acquisition using the mirror image relative feature. In this way, the image of the patient's cranial face before the injury is presented as shown in Fig. 4. Preferably, the spatial data of the original stereoscopic scene and the reconstructed stereoscopic image are stored in a database of the image processing system. Referring to FIG. 5, the comparison step S3 compares the original stereo image and the reconstructed stereo image through the image processing system, and defines a difference between the stereo images as a defect portion 2. More specifically, in this embodiment, the original stereoscopic image in the database and the spatial data of the reconstructed stereoscopic image are captured and compared by the image processing system, and the original stereoscopic image has a defect or damaged portion 1 The reconstruction of the stereoscopic image is the image of the patient before the injury of the patient's face. Therefore, the spatial data of the two will be different after comparison, and the difference between the spatial data of the two is defined as the defect portion 2, the image The processing system can clearly distinguish the damaged or defective parts by the defect portion 2 obtained after the comparison. Referring to FIG. 6 , the data extraction step S4 is performed in the image processing system, and the mechanical data received by the cranial face portion corresponding to the defect portion is extracted, and a reconstruction image is defined on the reconstructed stereo image. The mechanical compensation zone 3 for compensating the mechanical data of the defect portion 2 is compensated. More specifically, as described above, the image processing system has a plurality of pre-stored mechanical data corresponding to each part of a cranial face. Taking the mechanical data of the cranial face part corresponding to the defect part 2 in the database, taking the figure 6 as an example, the defect part 2 is located at the mandible, so the normal mandible in the database is taken. Corresponding to the mechanical information of the part at the defect part 2, reference to 201236638. Then, according to the definition above, the position of the stereo image is reconstructed, so that the Xt «Bay Area 3 ' is used as the follow-up plate setting of the plate 5, and the mechanical compensation zone of 6 is accepted. 3 Crossing the defect portion 2, connecting the Gu Yan bone around the defect portion 2, can compensate the force of the lower bone when biting. Through this step, the damage of the Gu Yan part is considered, so that the designed bone plate can further carry the mechanical load of the part to improve the stability of the hybrid. As shown in the supplementary diagram, the model design step s5 is based on the force to supplement the red: 3 surface job design - the bone plate model with thickness - τ is more evaluated, after defining the mechanical compensation zone 3, = The surface shape design of the mechanical compensation zone 3 is 'as shown in Fig. 7' so that one of the bone plate models 4 is complemented, and the surface shape of 3 is complementary 'to make the bone plate of the plate ι, Π "Zone 3 70 Fully tightly' improves the overall positioning precision and stability, and provides the supporting force and bearing capacity required for the defect. Among them, the plate model 4 is preferably based on the mechanical load of the defect zone 2 The positioning of the positioning hole 41 is mainly performed by simulating the direction of the force of the force corresponding to the force of the face of the face, so as to pass through the fixing member such as a screw. Step S4, according to the bone plate model 4, a bone plate of the bone plate and the bone plate model is produced. In more detail, the present embodiment uses a processing manufacturing unit to perform tilting according to the bone plate model and plan The production path of the bone plate is made by a through-tool machine. The manufacturing process is 201236638. Early 7G can be used as a processing system for Computer-aided manufacture, Computer-aided manufacture (CAM) or general computer processing design.
