Embodiment Construction

[0061] In order to better understand the technical solutions of the present invention, further description is given below through the accompanying drawings and specific embodiments.

[0062] The patient's skull is damaged, and the damage is large-scale damage. The trauma area is about 120mm × 120mm. According to the invention of this method, the skull defect is repaired. The process is as follows:

[0063] 1. The computer reads the DICOM format data of CT or MR of the patient's bones;

[0064] 2. The DICOM data of the patient's bone image is reconstructed in the coronal, sagittal and axial positions. Generate three phase profiles of the patient's skeleton. On the axial view of the patient's bone and referring to the coronal and sagittal views, a bezier curve for forming the titanium plate covering the bone defect of the patient was designed.

[0065] First, 11 control points are obtained at the defect in the first frame. Since the human body is basically symmetrical, these 1...

Abstract

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 of a patient for patients with bone defects and particularly for those with defective bones of complex structures. The method constructs a curved surface of the defective bone prosthesis according to the CT DICOM format data or MR DICOM format data of the bone of the patient; a titanium plate forming mould is designed according to the curved surface; then, the data of the mould is input into a digital control machine tool; a stamping mould needed by the design is machined by the machine tool; and the titanium plate is carried out stamping forming by the mould. Moreover, the CT DICOM format data or MR DICOM format data of the bone of the patient undergoes 3D reconstruction, and a reconstructed bone image is input to the digital control machine tool; and the digital control machine tool machines a bone prosthesis, and matching check between the bone prosthesis and a bone model of the patient is carried out so as to ensure that the prosthesis is completely matched with a skull of the patient.

Description

technical field [0001] The invention relates to a preparation method of a titanium alloy restoration body for human body defect, in particular to a method for obtaining a titanium alloy restoration body for defect bones by using die stamping and computer-aided design. Background technique [0002] Due to accidents, diseases and other reasons, the bones are severely damaged and osteonecrosis, so there must be an object to replace the bones to protect and support the human body. The medical community, academia and industry have been working on the research of defective bone restoration for decades. Titanium alloys have become a new favorite in clinical practice because of their good biocompatibility and easy shaping. The use of computer three-dimensional modeling to shape the restoration is also a hot research topic. [0003] The existing methods for preparing bone prostheses are as follows: [0004] Mold processing: The stamping mold is processed on the CNC machine tool, a...
