Abstract

A shaft for a micro-invasive surgical instrument includes a shaft tube with a proximal end portion and a distal end portion, a coupling device for detachable mechanical coupling of the shaft with a tool, and a rotation bearing, which mechanically connects the coupling device with the distal end portion of the shaft tube. The rotation bearing is configured in order to allow rotation of the coupling device with respect to the shaft tube about the longitudinal axis of the shaft on the distal end portion of the shaft.
