AI Technical Summary

Problems solved by technology

However, when 3D printing technology is used to produce and manufacture artificial prostheses, there is a lack of a method and device that can perform 3D reconstruction according to the actual situation of bone defects, and it is impossible to quickly establish a 3D model of human damaged tissue based on AI technology, so as to provide 3D Printing provides accurate data and precise positioning for 3D printing operations, improving the fit between 3D printed prostheses and damaged bone parts and the actual application effect of prostheses

Abstract

The invention relates to the technical field of 3D printing, in particular to an orthopaedic 3D printing method and device based on AI. The method comprises the following steps: acquiring tomography data of human skeleton tissues, and constructing a human skeleton virtual model; based on collected tomography data and diagnosis data, marking a bone defect part area in the human body bone virtual model; traversing a skeleton model database, and matching a three-dimensional model corresponding to the skeleton defect partial region; mapping the marked bone defect partial region to a corresponding three-dimensional model according to the diagnosis data to obtain a fitted bone defect model; and the obtained bone defect model is sliced and layered according to the vector direction of 3D printing, and a three-dimensional model of each slicing and layering angle is obtained for layered printing. According to the method, the tomography data are mapped into the created human skeleton virtual model, the damaged skeleton is matched with the three-dimensional model, and slicing and layered printing are carried out according to the skeleton defect model.

Description

technical field [0001] This application relates to the technical field of 3D printing, in particular to an AI-based orthopedic 3D printing method and device. Background technique [0002] With the continuous development of computer technology, laser 3D printing technology has also become a relatively advanced component manufacturing process, playing an increasingly important role in product research and development. Moreover, the entire process of 3D printing technology is based on computer control technology, and intelligent manufacturing is realized under the control of the computer. Looking at the entire 3D printing process, no matter from computer modeling, slicing or three-dimensional motion control of multi-axis devices, it is inseparable. Develop AI-based computer control technology. [0003] With the advancement of modern medicine, 3D printing technology is gradually used to print bone defects and 3D printing of orthopedic prostheses for the repair of bone defects i...
