Abstract
The invention relates to a shaft instrument (10) for laparoscopic and / or endoscopic interventions, comprising a proximal shaft portion (28) having a proximal shaft portion longitudinal axis, a distal shaft portion (30) having a distal shaft portion longitudinal axis, and a handling portion (14). The proximal shaft portion and the distal shaft portion are connected to one another in the region of a connecting joint (32) and are rotatable relative to one another, and at least one of the end faces of the two shaft portions facing the connecting joint is oriented at an angle deviating from 90° relative to the respective shaft portion longitudinal axis. The shaft instrument has an additional shaft portion located between the handling portion and the proximal shaft portion. The shaft instrument also has an axle which is flexible at least at the height of the connecting joint, the individual shaft and axle portions being connected to one another such that a relative rotation between the proximal shaft portion and the additional shaft portion is accompanied by a change in the angle between the proximal shaft portion longitudinal axis and the distal shaft portion longitudinal axis.
