Abstract

A surgical instrument is provided having a tubular shaft with working elements arranged at its distal end, at least one of which may be spread apart. The working elements engage through an actuator element with a handle arranged at the proximal end of the shaft for opening and closing the working elements. A continuous hollow channel is provided in the interior of the instrument, into which at least one additional instrument may be inserted. The hollow channel preferably has a cross section corresponding to the inner clearance diameter of the tubular shaft. The working elements are configured such that they do not extend into the cross section of the hollow channel either in opened or in closed condition.
