Abstract
An instrument for endoscopic surgery comprises a retractor having independently spreadable retractor blades pivotally mounted at the distal end of a tube, through which a balloon dissector can be passed. The blades are pivoted on axes transverse to the elongation of the tube. The blades are externally convex and internally concave in cross-sectional planes to which the elongation of the tube is perpendicular. The balloon is transparent, and the balloon dissector is provided with an image transmitter for visualization of tissue dissection.
