Embodiment Construction

[0034] Utilize the technology of the present invention, carry out clinical application in Beijing Temple of Heaven Hospital. The patient data collection was completed in the Tiantan Hospital Information Center, the CT image processing adopted the Mimics software system, the prosthesis design adopted the Surfacer software system, the titanium mesh pressing adopted the special-shaped curved surface rapid prototyping system, and the restoration model adopted the fused deposition rapid prototyping system. Comparing and cutting to form the final titanium mesh restoration, the specific steps are as follows:

[0035] (1) Firstly, a spiral CT scan is performed on the patient's skull, and the scanning interval is set at 2-3 mm. The present invention sets the spacing of the scanning layers according to the position of the patient's skull defect. If the shape of the defect is complex, such as the temple or the root of the ear, the scanning spacing is set to 2mm. If the shape change of t...

Abstract

The preparation process of skull repairing body of titanium alloy for cerebral neurosurgery and other fields is based on the CT image scanning of the patient, assembling the repairing body, data analysis in computer with common image processing software and reverse design software, reconstituting the 3D prototype of the patient head, designing the repairing body based on the 3D prototype, making the repairing body mold via the fast prototype system, and pressing the netted titanium plate based on the mold to form final repairing body. The present invention features the making of the repairing body mold via digital design technology, fast forming system with special curved surface and gradually forming method to press the netted titanium plate. The repairing body of the present invention has high precision, low cost, fast making process and other advantages.

Description

technical field [0001] The invention relates to a preparation method of a titanium alloy skull prosthesis, which is mainly used in the fields of cranial bone repair in neurosurgery, medical plastic surgery, cosmetic surgery and the like. Background technique [0002] Skull repair is a common surgical procedure in neurosurgery, medical plastic surgery, etc. The materials used mainly include: silicone rubber, polymethyl methacrylate (PMMA), good skull ratio and titanium alloy mesh. Among them, titanium alloy stencils have been widely used in clinical applications because of their good biocompatibility, non-toxicity and high strength. However, the current preparation process of titanium metal plate is either difficult to shape, or the production cost is high and the cycle is long, which seriously limits its popularization and application. At present, there are mainly the following three preparation processes: [0003] (1) Manual shaping This is a shaping method commonly used ...
