Novel Burr Hole Dilator for Endoscopic Surgery for Intracranial Hemorrhagic Lesion: Technical Note.

Abstract

When performing burr hole endoscopic neurosurgery, it is necessary to get enough surgical corridor. We have used various instruments to extend burr hole size, but it was cumbersome to use so many tools. In this report, we describe a novel instrument-a dilator attachment with a cordless handle to make it simple and safe to extend a burr hole. We developed this burr hole dilator attachment with blades on the side and an arc form on the bottom to prevent dural damage. It can be used to drill safely and efficiently. We describe some experiences of using this device. It is important to balance the maximization of the operation range and surgical invasiveness for endoscopic neurosurgery. This new dilator for extending a burr hole is a safe, useful device to get enough surgical view and easily perform a surgical procedure in endoscopic surgery. Our dilator for expanding a burr hole improves the work of endoscopic surgery on intracranial hemorrhagic lesions.
