Patent attributes
A medical instrument has a tubular shaft, a handle at a proximal end of the shaft and a movable working part at a distal end of the shaft, the shaft includes a shaft section having a curvature and being arranged between the distal end and the proximal end of the shaft. The handle and the working part are operatively connected via a force transmission element extending through the shaft. The force transmission element has a section arranged within the curved shaft section of the shaft, the section being guided on an inner surface of the shaft and having 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 a pin forming a hinged joint, such that each of the pins defines a rotation axis oriented substantially perpendicular relative to the shaft.
