The invention relates to a shaft instrument (10) for laparoscopic and / or endoscopic procedures, comprising a proximal shaft section (28) having a proximal shaft section longitudinal axis, and a distal shaft section (30) having a distal shaft section longitudinal axis, and a handling section (14), wherein the proximal shaft section and the distal shaft section are connected to each other in the region of a connecting joint (32) and are rotatable relative to each other, wherein at least one of the end faces of the two shaft sections facing the connecting joint is oriented at an angle deviating from 90° relative to the respective shaft section longitudinal axis, wherein the shaft instrument comprises an additional shaft section arranged between the handling section and the proximal shaft section, and wherein the shaft instrument has a shaft which is bendable at least at the level of the connecting joint.wherein the individual shaft and shaft sections are connected to each other in such a way that a relative rotation between the proximal shaft section and the additional shaft section is accompanied by a change in the angle between the proximal shaft section longitudinal axis and the distal shaft section longitudinal axis.
