Surgeons and medical students may be able to get better practice before surgery using new artificial organ models that are more lifelike than current models.Researchers from the University of Minnesota have created artificial organ models from a 3D printer that mimic the exact anatomical structure, mechanical properties and look and feel of real organs.The models include integrated soft sensors that can be used for practice surgeries to improve surgical outcomes for thousands of patients worldwide.“We are developing next-generation organ models for pre-operative practice,” lead researcher Michael McAlpine, an associate professor of mechanical engineering in the University of Minnesota’s College of Science and Engineering, said in a statement. “The organ models we are 3D printing are almost a perfect replica in terms of the look and feel of an individual’s organ, using our custom-built 3D printers.“We think these organ models could be ‘game-changers’ for helping surgeons better plan and practice for surgery,” he added. “We hope this will save lives by reducing medical errors during surgery.”The majority of 3D printed organ models are made using hard plastics or rubbers, which limits their application for accurate prediction and replication of the organ’s physical behavior during surgery. The models are often too hard… Read full this story
