New device for endoscopie image display during microsurgical clipping of cerebral aneurysms - Technical note

Abstract

Endoscopy in microsurgery is most effective when a single surgeon can monitor both endoscopic and microscopic images simultaneously. However, monitoring systems of this kind, such as a contemporary microscope equipped with a picture-in-mode function, are expensive. The present display system is connected to the endoscope video camera and mounted on the surgeon's head. The liquid crystal display is positioned just under the microscope eyepieces, so reducing the need for the surgeon to refocus and redirect the gaze during surgery. This system allows nearly simultaneous endoscopic and microscopic monitoring. No changes to the surgical microscope are necessary.
