Desenvolvimento de método para obtenção de guia cirúrgico para coluna vertebral utilizando tecnologia 3D

Abstract

The innovation process is increasingly evident, due to the large growth of research focused on the search for the development and use of new technologies, with the aim of improving health care at its different levels. In this way, the use of Three-Dimensional Technologies (3D), such as Additive Manufacturing (AM), defined as a manufacturing process through the addition of material in flat and successive layers, stands out in the optimization and modernization of invasive procedures, through the development and acquisition of biomodels and surgical guides that make the planning of the surgical process more realistic, as they allow the visualization of anatomical structures in a three-dimensional way, and allow the simulation of the entire surgical procedure. Thus, the application of AM in the manufacture of these devices allows comfort and precision to the surgical team, improving efficiency during surgery and, consequently, reflects in a greater acceptance and recovery of the patient in relation to conventional surgical methods. The objective of this study was to use three-dimensional technologies to develop and obtain a surgical guide for the spine region, aiming at optimizing surgical procedures. It was an exploratory action research with a qualitative approach and exploratory objective, elaborated through a case study, with a convenience sample, developed at LT3D-NUTES/UEPB. The surgical method through 3D technologies allows for greater interaction with the surgeon, which ensures more effective surgical planning, enabling an improvement in the precision of the insertion of pedicle screws, by allowing a detailed visualization of the pedicle canal and the bone stock in the vertebral body, allowing the surgeon to adopt the best angulation.
