摘要:
A medical tubular shaft instrument comprises a tubular shaft (12), a handle (32) at a proximal end (16) of the shaft (12) and a movable working part (22) at a distal end (14) of the shaft (12), wherein the shaft (12) comprises a shaft section (18) having a curvature (20) and being arranged between the distal end (14) and the proximal end (16) of the shaft (12), wherein the handle (32) and the working part (22) are operatively connected via a force transmission element (44) extending through the shaft (12) and being movable in a longitudinal direction of the shaft (12), wherein the force transmission element (44) has a section (52) arranged within the curved shaft section (18) of the shaft (12) which is guided on an inner surface (88) of the shaft (12) and which comprises a plurality of interconnected single elements (54) arranged one after the other along the longitudinal direction of the shaft (12). The single elements (54) are pairwise connected by means of a pin (76) forming a hinged joint (78), wherein each of the pins (76) defines a rotation axis (80) oriented substantially perpendicular relative to the shaft (12).
