Application of new electrosurgical devices and probes in endoscopic neurosurgery

Complex demands and new indications in neurosurgery have led to the need for new electrosurgical generators (ESUs). For the first time, newly developed, automatically controlled ESUs make it possible to use extremely small and flexible instruments safely and to achieve reproducible microcuts and microcoagulations. These specifications make them suitable for neuroendoscopic interventions. In a series of more than one hundred patients with different intracranial and intraspinal pathologies the new electrosurgical devices and probes were used not only for coagulation but also for cutting. The main indications were endoscopic ventriculo-cisternostomy, ventriculo-cystostomy, and membranectomy. The electrosurgical generators as well as the bipolar microcoagulation and -cutting probes proved to be safe and effective for neuroendoscopic interventions.
