Considerando a crescente necessidade de mĂ©todos eficazes, acessĂveis e econĂłmicos na
formação cirĂșrgica, esta dissertação propĂ”e e explora o desenvolvimento de uma solução
baseada em realidade mista como um complemento viåvel aos métodos tradicionais. A
realidade mista, ao combinar elementos de realidades virtual e aumentada, permite a
simulação de procedimentos cirĂșrgicos complexos, sem as restriçÔes impostas pelos mĂ©todos
tradicionais. Com este objetivo, foram concebidos e implementados exercĂcios num simulador
cirĂșrgico imersivo designado OrthoSim, orientado para as ĂĄreas da laparoscopia e da
artroscopia, com recurso aos dispositivos Meta Quest 3. O simulador integra exercĂcios clĂnicos
com um sistema de gamificação para potenciar a motivação e o envolvimento dos utilizadores.
O sistema desenvolvido inclui ainda uma plataforma web complementar, que permite
personalizar os exercĂcios e gerir diferentes configuraçÔes do mesmo com nĂveis de dificuldade
distintos. Além disso, disponibiliza funcionalidades de registo, autenticação e visualização do
desempenho dos utilizadores. A avaliação da solução foi realizada atravĂ©s da âEscala de
Usabilidade do Sistemaâ, aplicada a uma amostra de 11 participantes, dos quais trĂȘs eram
profissionais da ĂĄrea cirĂșrgica e os restantes nĂŁo possuĂam formação neste domĂnio. A
pontuação obtida (74,3) indica uma boa usabilidade global, com destaque para a perceção
especialmente positiva por parte dos cirurgiĂ”es. Verificou-se ainda uma influĂȘncia positiva na
sua adaptação à realidade mista e na motivação no treino. Deste modo, o sistema demonstrou
elevado potencial como ferramenta complementar no ensino cirĂșrgico, aliando acessibilidade,
segurança e realismo na pråtica técnica. Apesar dos resultados promissores, a reduzida
dimensĂŁo e representatividade da amostra limita a generalização dos dados, ainda que trĂȘs
cirurgiĂ”es tenham sido incluĂdos. Trabalhos futuros estĂŁo a ser planeados com o intuito de
validar o simulador em contextos de treino reais, incluindo uma amostra mais alargada e
diversificada de profissionais da saĂșde, de modo a avaliar o seu impacto na aquisição de
competĂȘncias tĂ©cnicas e na eficĂĄcia da formação cirĂșrgica em larga escala.
Considering the growing need for effective, accessible and economical methods in surgical training, this dissertation proposes and explores the development of a solution based on mixed reality as a viable complement to traditional methods. By combining elements of virtual and augmented reality, mixed reality allows complex surgical procedures to be simulated without the restrictions imposed by traditional methods. To this end, exercises were designed and implemented in an immersive surgical simulator called OrthoSim, aimed at the areas of laparoscopy and arthroscopy, using Meta Quest 3 devices. The simulator integrates clinical exercises with a gamification system to boost user motivation and involvement. The system also includes a complementary web platform, which allows you to personalise the exercises and manage different configurations with distinct levels of difficulty. It also provides features for registering, authenticating and visualising the user performance. The solution was evaluated using the âSystem Usability Scaleâ, applied to a sample of 11 participants, three of whom were surgical professionals and the rest had no training in this field. The score obtained (74.3) indicates good overall usability, with a particularly positive perception from surgeons. There was also a positive influence on their adaptation to the mixed reality and on their motivation in training. In this way, the system showed great potential as a complementary tool in surgical teaching, combining accessibility, safety and realism in technical practice. Despite the promising results, the small size and representativeness of the sample limits the generalisability of the data, even though three surgeons were included. Future work is being planned with the aim of validating the simulator in real training contexts, including a wider and more diverse sample of healthcare professionals, in order to assess its impact on the acquisition of technical skills and the effectiveness of large-scale surgical training.
