Study on Minimally Invasive System of Brain Surgery

Abstract

The aim of this research was to examine the thermal injury in the brain after a minimally invasive electrosurgery with the chromium nitride (CrN) and diamond-like carbon (DLC) surface modifications. Three-dimensional (3-D) brain models were reconstructed to simulate the electrosurgical procedure. Data indicated that the temperature decreased significantly when minimally electrosurgery with nanostructured CrN and DLC thin films were used, and that it continued to decrease with increasing film thickness. The present study reveals that the novel nanostructured thin film on electrode substrates is an effective means of improving the performance of reducing excessive thermal injury and uniformly distributing temperature in the brain. However, further tests in the clinical trial must be evaluated to confirm the effect and safety of promising findings in the brain electrosurgery.
