We developed an Er: YAG laser surgery system for glioma removal. The purpose of our laser system is to ablate brain tumor as precisely and efficiently as possible, without collateral tissue damage. In order to evaluated the efficiency of ablation and the thermal damage to the tissue around the ablation holes, we irradiated an Er: YAG laser to pig brain tissues in vitro with respect to laser repetition rate (10, 20, 25Hz) at a fluence (113.7J/cm2), a scan speed (1mm/s). This report showed that it could be applied as our laser system for the brain tumor removal, which the most efficient ablation condition was under a specific site at10Hz using an Er: YAG laser surgery system.
