Virtual reality training platform for flexible ureterorenoscopy interventions with a minimally invasive surgical robot

The total number of ureteroscopy (URS) interventions during the past years has dramatically increased due to the ongoing technological advances and the benefits associated with these techniques. However, the current URS procedure presents some drawbacks to urologic surgeons. The LITHOS project was created with the main objective of developing a surgical robotic system for flexible ureterorenoscopic lithotripsy interventions, offering a technological solution that meets the real needs of both patients and surgeons in this type of procedures. In this paper, a virtual reality environment for flexible ureterorenoscopy interventions is presented. The proposed environment provides a suitable training platform for surgeons manipulating the surgical robotic system

Entorno didáctico de bajo coste para formación en tecnologías de cirugía guiada por imagen y robótica

Este trabajo de investigación presenta un nuevo entorno didáctico de bajo coste para la formación ingenieril de temáticas de cirugía guiada por imagen y robótica. Con este entorno se pretende mejorar la motivación y autonomía del alumnado, que hasta el momento se hallaba acotada debido al alto componente teórico de las sesiones impartidas. El entorno está formado por un phantom, una herramienta software, un sistema robótico y un manipulador que permite obtener una realimentación háptica. Se ha llevado a cabo una experiencia piloto en la asignatura de cuarto curso "Simulación y planificación quirúrgica" del Grado de Ingeniería Biomédica de la Universidad Politécnica de Madrid. Los resultados de las encuestas llevadas a cabo muestran que la nueva metodología mejora en todos los casos los valores obtenidos usando la metodología clásica basada en la clase magistral y prácticas

Position Based Model of a Flexible Ureterorenoscope in a Virtual Reality Training Platform for a Minimally Invasive Surgical Robot

Although the total number of ureteroscopy interventions during the past years has significantly increased, current flexible ureteroscopy procedures still present some limitations to urologic surgeons. However, nowadays different robotic systems have been developed in order to reduce those limitations. Flexible ureteroscopy robots provide a technological alternative which combines the benefits that this type of procedures offers to the patients, and solutions to the problems encountered from the surgeons perspective. In this paper, a virtual reality training platform for robot-assisted flexible ureterorenoscopy interventions is presented. A position based model for the virtual flexible endoscope is detailed and a standard user interface for the training platform is designed. Moreover, a comparative analysis of the performance of the training platform in different scenarios, including the navigation through a three-dimensional ureterorenal model, is presented. The obtained results determine that the training platform presents different computational rates depending on the complexity of the implemented environment and on the number of collisions and constraints that have to be handled. Nevertheless, the virtual model is visually plausible, effective for real-time user interaction and suitable for training.Ministerio de Economía, Industria y Competitividad, Gobierno de España-10.13039/5011000101983.745 JCR (2019), Q1, 35/156 Computer Science, Information Systems, 61/266 Engineering, Electrical & Electronic; Q2, 26/90 Telecommunications0.775 SJR (2019) Q1, 44/393 Computer Science (miscellaneous), 73/676 Engineering (miscellaneous); Q3, 148/626 Materials Science (miscellaneous)No data IDR 2019UE
