A New Irrigation System (Endosplash) for a Rigid Endoscope in Trans-sphenoidal Endoscopic Surgery

抄録

Obstruction of the visual field by blood is a major hindrance during endonasal endoscopic surgery, and a rapid and effective method for cleaning the lens is needed. We developed a new lens-cleaning system that does not employ a sheath or an irrigation-suction system. It is a 20-mm long cylinder with side holes that is attached to the barrel of the endoscope and is connected to a syringe containing saline. When the syringe is pressed, saline flows down to the tip along the barrel and washes the lens without requiring a sheath. We report the use of the system in six cases of endonasal endoscopic surgery. The lens was wiped significantly less often than during similar surgery performed without the use of this system. The Endosplash is simple and enables the surgeon to clean the lens with a single press of a syringe, thereby greatly enhancing the efficacy of endoscopic surgery.
