We held a hands-on seminar for trainees and students. This time, with the cooperation of Stryker, we conducted hands-on drilling sessions and hands-on brain tumor removal using an ultrasound device on a brain tumor model. Twelve people, including trainees from other hospitals, participated and experienced Neurosurgery. We plan to hold hands-on sessions on a regular basis in the future. We look forward to seeing everyone with an interest in surgery and Neurosurgery participate.
