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.
A novel retractor has been designed to achieve atraumatic retraction of the liver and displacement of hollow viscera during endoscopic surgery. The functional section of the instrument, when locked, forms a silicon-covered uniplanar hook which can be deployed for horizontal lift of solid organs such as the liver or be used to engage bowel for displacement from the operative field. Following laboratory testing, the instrument has been evaluated clinically and its ease of deployment and atraumatic nature have been confirmed. It has been found to be particularly effective for elevation of the thick fatty left lobe of the liver during antireflux surgery.
