Abstract

A medical tubular shaft instrument comprises a tubular shaft, a handle at a proximal end of the shaft and a movable working part at a distal end of the shaft, wherein the shaft comprises a shaft section having a curvature and being arranged between the distal end and the proximal end of the shaft, wherein the handle and the working part are operatively connected via a force transmission element extending through the shaft and being movable in a longitudinal direction of the shaft, wherein the force transmission element has a section arranged within the curved shaft section of the shaft which is guided on an inner surface of the shaft and which comprises a plurality of interconnected single elements arranged one after the other along the longitudinal direction of the shaft. The single elements are pairwise connected by means of a pin forming a hinged joint, wherein each of the pins defines a rotation axis oriented substantially perpendicular relative to the shaft.
