Abstract

An electrosurgical tubular shaft for use with a surgical instrument grip for formation of an electrosurgical tubular shaft instrument is provided. The tubular shaft comprises a tube, an electrosurgical tool arranged at the distal end on the tubular shaft, at least one electric connection line electrically connected to the tool and extending in the tube, and at least one coupling element arranged at the proximal end on the tubular shaft for interacting with at least one corresponding coupling element of the instrument grip for releasably coupling the instrument grip to the tubular shaft. The tube comprises an outlet opening which is arranged distally of the at least one coupling element and through which the at least one connection line issues from the tube. The tubular shaft comprises an electric connection element for an electric energy supply. A surgical instrument grip and an electrosurgical tubular shaft instrument are also provided.
