26Examination of surgical operation methods in scoliosis in collaboration with Shinshu University’s Medical School. Although there are many physical training methods for weight reduction, some of them don’t reveal their eects from the viewpoint of mechanical engineers. Our simulation method demonstrates mechanical conditions in our body and the results may lead to more ecient training methods for our beautiful life!BioengineeringMichihiko KosekiAssociate ProfessorProposing reliable medical techniques through computationalbiomechanical simulationsDepartment of Machinery and RoboticsSurgical operations are sometimes required to fix severe bone fractures or muscle injuries. Here, if we can estimate mechanical conditions of our body parts and/or surgical instruments prior to the operation, the information will be greatly helpful to avoid surgical errors or further surgeries. Our laboratory examines patient-specific biomechanical simulation methods. That is, we fabricate a computational model with the exact shape of the patient based on clinical X-ray CT images, and perform analyses to estimate mechanical states of bones or artificial instruments in our body. Collaboration with medical doctors leads us to propose novel medical techniques.Associate Professor Koseki took his current position in 2009 after working as an engineer at Fujitsu Limited and an assistant professor at Tokyo Institute of Technology. His research interests include computational biomechanics, medical imaging techniques and bio-inspired robotics.Our research solutions will powerfully support medical doctors on both diagnoses and treatments for illnesses or injuries in orthopedic elds. Patients can also obtain great benets including personalized and information-rich informed consent for their own treatments. We aim to realize a world which is sensitive to the needs and desires of doctors, patients, and everyone.Outlook for researchWe regard living organs of "humans" from the perspectives of "mechanical engineering" and "information engineering.“ A diverse range of knowledge makes our students enjoy a variety of career paths after graduation.Outlook for students after graduation“Scoliosis”(Spinal axis has 3D deviation)In order to realize reliable surgical operation…BEFOREAFTERExperimental -Computational research approaches!x,y,z fixedz fixedxyzAxons elongated randomly by normal culture (left) and Axons oriented straight by controlling adherence property of culturing surface (right)Cell stretching device for reproducing the brain deformation in head impactBioengineeringHiromichi NakadateAssociate ProfessorFrom neurotraumato neuroregenerationDepartment of Machinery and RoboticsRepetitive brain concussion in playing football, judo, and rugby induces cognitive dysfunctions such as memory dysfunction. The brain becomes vulnerable and sensitive to stimuli by repeated head collisions, resulting in decreasing the threshold of brain injury. The rapid deformation of brain tissue is typically caused by head impact in traffic accidents because the inertia force is applied to the brain tissue by sudden acceleration and deceleration of the head. Thereby neurons are stretched, and axons, which play a role in neurotransmission, are injured and disrupted. We have developed the criteria of axonal injury through the impact loading experiment of brain neuronal cells to better understand the mechanism of axonal injury in repetitive brain concussion.Associate Professor Nakadate took his current position in 2018 after working as an assistant professor at Tokyo Metropolitan University. His research eld is brain injury biomechanics.The measuring accurately the condition and behavior of brain cells exposed to mechanical stress allows us to predict brain neurological damage that can not be detected the diagnostic imaging such as CT and MRI by computational simulation, and this study leads to a novel diagnosis system and establishing safety criteria of automobile.Outlook for researchStudents can learn the logical thinking, the problem solving ability and communication skills through studying autonomously. They also can enhance a connection with collegers through the life of laboratory.Outlook for students after graduation
