specific Embodiment approach 1

[0022] Specific implementation mode one: combine Figure 1 to Figure 4 Describe this embodiment, a 3D printed skull replacement device in this embodiment, including a fixed piece 4, a dense layer 1, a dense layer 2 and a transition layer 3, the fixed piece 4 and the dense layer 1 are formed from the top The bottom is located above the transition layer 3 in sequence, the dense layer 2 is located below the transition layer 3 and the dense layer 1 and the dense layer 2 are connected through the transition layer 3, the dense layer 1, the transition layer 3 and the dense layer Layer 2 has the same shape as the defective skull, and transition layer 3 is a microscopic truss structure.

[0023] The connection between the present embodiment and the skull during use is installed on the outer periphery of the fixing piece 4 through a plurality of bolts, so as to realize the connection between the skull and the present embodiment.

specific Embodiment approach 2

[0024] Specific implementation mode two: combination Figure 2 to Figure 4 This embodiment is described, and this embodiment also includes an active coating 5 deposited on the outer surfaces of the dense layer 1 , the dense layer 2 , and the transition layer 3 . Such setting not only preserves the mechanical properties of the metal matrix, but also takes into account the compatibility and biological activity of the coating. The other composition and connection relationship are the same as those in the first embodiment.

specific Embodiment approach 3

[0025] Specific implementation mode three: combination figure 2 The present embodiment will be described. The active coating layer 5 of the present embodiment is a hydroxyapatite coating layer. Such setting is conducive to the attachment and growth of tissue cells and promotes osseointegration. Other compositions and connections are the same as those in the second embodiment.

Abstract

A skull replacing apparatus of 3D print and a manufacturing method thereof relate to a skull replacing apparatus and a manufacturing method thereof. In order to solve the problem of dysfunction due to the fact that the existing skull replacing object can't satisfy the refine requirement to a patent defect portion so that the cerebral tissue can't be fully protected and the skull replacing object usually doesn't match with the patent skull, the invention provides a skull replacing apparatus. The apparatus comprises a fixation piece, a compact substance layer 1, a compact substance layer 2 and a transitional layer, wherein the fixation piece and the compact substance layer 1 are located above the transitional layer; the compact substance layer 2 is located below the transitional layer and the compact substance layer 1 is connected to the compact substance layer 2 through the transitional layer; the compact substance layer 1, the transitional layer and the compact substance layer 2 have the same shape with the defect skull; and the transitional layer is a micro truss structure. The method comprises: a. imaging the damaged skull with 3D so as to determine the geometry size and parameter of the skull to acquire original datum of the skull needed to be replaced; b. designing a three-dimensional model of a skull replacing structure and printing the designed model; c. and improving the surface of a sample. The skull replacing apparatus and the manufacturing method thereof are suitable for skull replacement.

Description

technical field [0001] The invention relates to a skull replacement device and a preparation method thereof, in particular to a 3D printed skull replacement device and a preparation method thereof. Background technique [0002] As a medium for transmitting external shocks to the brain, the skull plays an important role in maintaining the safety of human life. Injury caused by extrusion and impact of foreign objects on the skull is a common cranial trauma disease in clinical medicine. Worldwide, traumatic brain injury accidents due to vehicle crashes and sports activities account for millions of accidents each year. The cranium cannot be restored after injury, so research on cranial replacements is of paramount importance. [0003] Existing cranial replacements cannot meet the detailed requirements of the patient's defect site, so that the brain tissue is not fully protected, and there are often problems of dysfunction due to mismatch. Contents of the invention [0004] ...
