Outline of Final Research Achievements

We performed animal experiments enabling superminimally invasive endoscopic surgery using multifunctional treatment system with laser irradiating endoscope. This endoscope has function of measuring volume, blood flow, temperature, and distance of the tartet, and was developed and patented by our team. Especially, we focused on accurate and prompt hemostasis, which is a current problem of an endoscopic intraventricular surgery, and we optimized the laser irradiating intensity, time, and distance to target in using this treatment system. Furthermore, we proved availability of this system not only in the air but also in the cerebrospinal fluid. This system can contribute to improve accuracy and safety of current endoscopic surgery.
