Skull repair material and preparation method thereof

Abstract

The invention discloses a preparation method of a skull repair material, which comprises the following steps: (1) obtaining three-dimensional data of a skull repair patch based on image data of a skull defect part of a patient; (2) based on the three-dimensional data of the skull repair patch, preparing a skull repair patch blank from base material metal powder through the 3D printing technology, wherein the skull repair patch blank comprises an inner surface layer, an outer surface layer and a loose mesh layer arranged between the inner surface layer and the outer surface layer; and a plurality of blind holes are formed in the inner surface layer and the outer surface layer; and (3) adding the first composite powder into the blind hole in the outer surface layer of the skull repair patch blank, and adding the second composite powder into the blind hole in the inner surface layer of the skull repair patch blank to obtain the skull repair material. In addition, the invention further discloses the skull repair material which is prepared by adopting the preparation method.

Description

technical field [0001] The invention relates to a material and a preparation method thereof, in particular to a restoration material and a preparation method thereof. Background technique [0002] Skull defects are one of the common problems in neurosurgery. The main method of clinically repairing skull defects is cranioplasty, which mainly includes autologous bone graft and artificial bone graft repair materials. Although autologous bone grafting is considered to be the most ideal bone graft material, autologous bone grafting has problems such as difficult storage of autologous bone, high infection rate, limited bone source, poor plasticity, poor plastic effect, and high cost. Therefore, the clinical application of autologous bone grafts has been greatly limited, and artificial bone graft repair materials have gradually replaced autologous bone grafts. [0003] At present, artificial bone graft repair materials are divided into non-metal repair materials and metal repair ...

AI Technical Summary

Problems solved by technology

However, the forming of titanium mesh is mainly made by machine tool casting and mold pressing, which is prone to problems such as wrinkling, edge warping and insufficient strength due to the influence of the process level

In addition, this method has problems such as long production cycle, poor adhesion between the repair material and the surface of the skull, manual cutting and shaping according to the actual situation of the patient's bone window during the operation, high infection rate, and unsatisfactory repair effect.
