Endoscopy under operating microscope. A new device

Existing technical conditions make it difficult for a single surgeon to simultaneously observe the endoscope and the observation field of the operating microscope. Video endoscopy is not adapted, because it respects neither the constraints of microsurgery (the surgeon has to stop observing the binoculars of the microscope to watch the video screen) nor the micromanipulations necessary for the specialties using micro endoscopy. A new device is described that closely joins endoscope and microscope. This coupling device allows the surgeon to permanently control and alternate the images according to his choice. The surgeon is able to observe in the binoculars the images transmitted by the endoscope and/or the operating microscope. This device respects the requirements of the microscope and, thanks to its optical capabilities, the endoscopic image is improved. The professions requiring double observation will improve their ability in diagnosis and therapy.
