Embodiment Construction

[0007] A kind of EH composite bone cement plate skull repair method of the present invention, before carrying out cranioplasty, first carries out CT examination to patient, collects the data (such as size, thickness and convex-concave radian) of the position of the symmetrical side of skull defect position, The data is sent to the CNC machine tool, and the data is processed in the way of jigsaw puzzles to reproduce the skull defect model. According to the skull defect model, EAM medical resin and hydroxyapatite are the main raw materials to make EH composite skull cement plate. The establishment of the data model is based on the OM line of the skull and the anteroposterior midline, and a 1mm×1mm square cutting block is digitally marked to form a database, and the data and images are converted based on this.

Abstract

A method for repairing skull with EH-type composite bone-cement plate includes such steps as CT examining to acquire the data about the damaged part of skull, data processing to form a data model, and preparing relative EH-type composite bone-cement plate.

Description

technical field [0001] The invention relates to a skull repair method with an EH composite bone cement plate. Background technique [0002] At present, the EH composite bone cement plate is used for cranial repair surgery, but due to the individual differences in human skulls and the different defect locations, a large number of professionals are required to collect individual molds and prefabricate the EH composite bone cement plate clay skull. The EH composite bone cement plate skull prepared by this method often cannot completely coincide with the skull defect, and the phenomenon of large or small curvature often occurs. Contents of the invention [0003] The invention provides a cranial repair method using EH composite bone cement plate to make jigsaw puzzles using the data of the symmetrical parts of the skull. [0004] The technical scheme of the present invention is as follows: before carrying out cranioplasty, carry out CT examination to patient earlier, collect t...
