Embodiment Construction
[0062] In order to better understand the technical solutions of the present invention, further description will be given below with reference to the drawings and specific embodiments.
[0063] The patient's skull was injured, and the injury was a large-area injury, and the trauma area was about 120mm × 120mm. According to the invention of the method, the skull defect was repaired, and the process was as follows:
[0064] 1. The computer reads the DICOM format data of CT or MR of the patient's skull;
[0065] 2. The DICOM data of the patient's skull image is reconstructed in the coronal, sagittal and axial positions. Generate three phase sectional views of the patient's skull. On the axial view of the patient's skull and referring to the coronal and sagittal views, design the bezier curve for the titanium plate to cover the defect of the patient's skull.
[0066] First, 11 control points are obtained at the defect in the first frame. Since the human body is basically symmetri...

The invention relates to a method for obtaining a titanium alloy prosthesis for human defective bone through mould stamping. The method provides the titanium alloy bone prosthesis which has high precision and meets the individual requirements for patients with defective bones of complex structures. The method comprises the following steps: constructing a curved surface of the defective bone prosthesis according to the DICOM format data of the CT or MR of the bone of the patient; designing a titanium plate forming mould according to the curved surface; then, inputting the data of the mould into a digital control machine tool; machining a stamping mould based on the design by the machine tool; and stamping and forming the titanium plate by the mould; moreover, three-dimension reconstructing the DICOM format data of the CT or MR of the bone of the patient, and inputting a reconstructed bone image to the digital control machine tool; and machining a bone prosthesis by the digital control machine tool, and matching and checking with the bone model of the patient, ensuring that the prosthesis is completely matched with a skull of the patient.
Description
technical field [0001] The invention relates to a method for preparing a human body defect skull titanium alloy prosthesis, in particular to a method for obtaining a defect skull titanium alloy prosthesis by using die stamping and computer-aided design. Background technique [0002] Due to accidents, diseases and other reasons, the skull is severely damaged and osteonecrosis, so there must be an object to replace the skull to protect and support the human body. The medical community, academia and industry have made decades of efforts on the study of defective skull prosthetics. Titanium alloy has become a new favorite in clinic because of its good biocompatibility and easy shaping. The use of computer three-dimensional modeling method to shape the restoration is also a hot spot in research. [0003] The current methods for preparing skull prostheses are as follows: [0004] Die processing: The stamping die is processed on the CNC machine tool, and then the titanium plate ...
