Personalized skull dummy and preparation method thereof

Abstract

The invention discloses a personalized skull dummy and a preparation method thereof. In the personalized skull dummy, a medicinal metal material is used as a substrate, and a plurality of meshes are arranged on the substrate. The invention is characterized in that: the personalized skull dummy has a smooth profile edge; and the profile of the personalized skull dummy is matched with the profile of the defective part of the skull of a patient. The drawback that the edge of the skull metal dummy is coarsened when the edge profile of a skull metal dummy is trimmed after the three-dimensional forming of the skull metal dummy is accomplished in the prior art is overcome. The invention also discloses a preparation method of the personalized skull dummy, which comprises: acquiring the data on the skull image of a patient; performing the computer-based three-dimensional reconstruction of the skull and the computer-assisted design of the skull dummy; outputting dummy curved surface data output; acquiring a corresponding two-dimensional plane of the three-dimensional curved surface by computing; designing the skull dummy with the personalized profile by using the two-dimensional plane graphwith the specific edge profile; processing and forming the metal dummy; and the like.

Description

technical field

[0001] The invention belongs to the field of neurosurgical skull repair, in particular to a personalized skull prosthesis for replacing skull defect bones and a preparation method thereof. Background technique

[0002] In the field of neurosurgery, when the following traumas or diseases occur, the skull needs to be resected and repaired: A. Head trauma; B. Intracranial infection or tumor; C. Cerebral edema or increased intracranial pressure; D. Skull deformity, etc. . In order to restore the airtightness of the cranial cavity and prevent further neurological symptoms after skull defect, skull defect repair is required.

[0003] Due to the good biocompatibility, non-toxicity and high strength of pure titanium, titanium alloy and other materials, they are more suitable for the repair of skull defects caused by craniocerebral injury, intracranial tumor surgery or decompressive craniotomy. universal application. However, a problem that has always existed in th...
