HUVANT, a spin-off from the University of Milano, develops innovative virtual and haptic models of brain tumor by combining immersive virtual reality with physical 3D models that provide realistic functional and tactile feedback. This integrated simulation platform enables medical students, residents, and surgeons to perform precise surgical planning, facilitating patient-specific, less-invasive procedures. By offering advanced tools for planning, simulation, and explanation of surgical practices—from the simplest to the most cutting-edge techniques—HUVANT revolutionizes surgical training. It enhances the efficiency of residents' studies, allowing them to experience true human anatomy beyond the operating room.
