Training of Intra-Axial Brain Tumor Resection Using a Self-Made Simple Device with Agar and Gelatin.

Introduction: Self-made devices composed of agar and gelatin gel were used for resident training in intra-axial brain tumor resection. The mixture gel of agar and gelatin is retractable and can be suctioned. Hardness of the gel depends on the concentration of the solution.

Training in Cerebral Aneurysm Clipping Using Self-Made 3-Dimensional Models.

Introduction: Recently, there have been increasingly fewer opportunities for junior surgeons to receive on-the-job training. Therefore, we created custom-built three-dimensional (3D) surgical simulators for training in connection with cerebral aneurysm clipping.

Methods: Three patient-specific models were composed of a trimmed skull, retractable brain, and a hollow elastic aneurysm with its parent artery.
