PURPOSE Minimally Invasive Surgery (MIS) is a widely used surgical technique that requires a long training process due to its difficulty and complexity. We developed an Augmented Reality Haptic (ARH) System based on electromagnetic tracking devices for use in creation training models (computer-enhanced trainers), in computer-assisted surgery or(More)
In this paper, the development of an assisting system for laparoscopic surgical training is presented. With this system, we expect to facilitate the training process at the first stages of training in laparoscopic surgery and to contribute to an objective evaluation of surgical skills. To achieve this, we propose the insertion of multimedia contents and(More)
PURPOSE Laparoscopic surgery is commonly used in many surgical procedures but requires a learning process to develop the necessary skills. Virtual reality simulators play an essential role within the training curricula. This paper aims to determine whether training in SINERGIA VR simulator allows novice surgeons to improve their basic psychomotor(More)
Laparoscopic instrument tracking systems are an essential component in image-guided interventions and offer new possibilities to improve and automate objective assessment methods of surgical skills. In this study we present our system design to apply a third generation optical pose tracker (Micron-Tracker®) to laparoscopic practice. A technical evaluation(More)
PURPOSE The laparoscopic suturing task is a complex procedure that requires objective assessment of surgical skills. Analysis of laparoscopic suturing task components was performed to improve current objective assessment tools. METHODS Twelve subjects participated in this study as three groups of four surgeons (novices, intermediates and experts). A(More)
PURPOSE Laparoscopic techniques have nowadays become a gold standard in many surgical procedures, but they imply a more difficult learning skills process. Simulators have a fundamental role in the formative stage of new surgeons. This paper presents the construct and face validity of SINERGIA laparoscopic virtual reality simulator in order to decide whether(More)
A key concern in the design of a simulator is the level of realism necessary for proper training, and the underlying question about the level of fidelity required. A new experimental method for surgeon sensory interaction characterization has been defined and implemented. It aims to determine the relative importance of three components of surgical skill(More)
This work describes the design and application of multimedia contents for web technologies-based training in minimally invasive surgery (MIS). The chosen strategy allows knowing the deficiencies of the current training methods so new multimedia contents can cover them. This study is concluded with the definition of three different types of multimedia(More)
