Desenvolvimento de modelo anatômico tridimensional de sistema ventricular encefálico pelo método de manufatura aditiva por impressão 3D

Abstract

The study of human anatomy is common to practically every medical school. Currently, this discipline has undergone reformulations in order to make this content more profitable, raising students' interest better. The impression by means of additive manufacture of anatomical pieces in 3D has been shown a possibility for this reality. In addition to being a novelty in the medical academic environment, 3D printing modeling opens up a range of opportunities in the production of new models, including pathological ones, for a greater technical and didactic collection in human anatomy classes, guaranteeing a low cost. This research aimed to create anatomical parts by means of additive manufacture by 3D printing of the brain ventricle system. The pieces were selected and worked on public domain software, produced by the 3D printer by the authors themselves, translated into a format in which it is possible to use them in human anatomy classes. Four anatomical pieces were printed in 3D of the brain ventricle system, one of them being the anatomical encephalic ventricles, a second one simulating these structures affected by microcephaly, a third similar, but demonstrating the involvement by hydrocephalus and, finally, a fourth piece, all disassembled anatomical ventricles for better demonstration of the creation of the pieces. At the end of this research, it was possible to make pieces using a 3D printer with a high degree of resemblance to the real models, respecting the anatomical and pathological size scales and anatomical and pathological domains evidenced in computed tomography and magnetic resonance, for hydrocephalus and microcephaly pathologies and their configuration anatomical pattern.
