An instrument for manipulating organs in endoscopic procedures in the interior of the body includes two spreading members at the distal end of the instrument. The spreading members can be swiveled outwardly and actuated by means of a handle at the proximal end of the instrument. A control member displaceably guided in the instrument shaft connects the handle and spreading members. The distal end of the instrument is bent in such a way that the spreading members spread out in a curved plane so that organs can be reliably guided with the manipulator.
