title: A multifunctional, modified rigid neuroendoscopic system: clinical experience with 83 procedures. Technical note.
abstract: The authors combined a monopolar electrode and a suction/irrigation channel with a 0 degrees, 4-mm Hopkins rigid telescope into a single multifunctional unit. This three-in-one instrument is inserted through a lightweight 7.5-mm outer sheath, which is fixed separately. A fourth instrument (for example, a balloon catheter or a biopsy forceps) can be introduced and manipulated independently with the other hand. All endoscopic procedures were performed with a trephine to create a 15-mm craniotomy. After opening the dura mater, ventricles were tapped with a brain needle, which was followed by the insertion of the rigid scope for visualization. The telescope was then withdrawn momentarily; the outer sheath was introduced into the ventricle and fixed over the area of interest. The definitive procedure was then performed with ease by using the multifunctional three-in-one instrument in one hand and a fourth instrument in the other hand. This novel neuroendoscopic system has been used in clinical testing at the Vidyasagar Institute of Mental Health and Neurosciences since May 1998. Thus far, 83 neuroendoscopic procedures have been successfully performed with the aid of this instrumentation system, which has proven to be safe, versatile, and cost-effective, allowing a greater degree of freedom for the neurosurgeon.
