1. A video endoscope, comprising
a shaft comprising
a rigid, proximal-side section, anda distal section that is laterally deflectable from a central longitudinal axis of the shaft, an imager and an illuminator that are arranged at a distal end of the deflectable section, a rod-like pull element arranged in the shaft in an off-center fashion with respect to the central longitudinal axis, a housing that is arranged at a proximal end of the shaft, a control element arranged at the housing for controlling the deflection of the shaft, and a push tube that encases an exterior side of the pull element, wherein the pull element is, at a proximal side thereof, coupled with the control element and, at a distal side thereof, coupled with the distal end of the deflectable section of the shaft in such a way that a movement of the pull element in the proximal direction that is induced by the control element effects a lateral deflection of the deflectable section, wherein the rod-like pull element extends into an interior clearance of the housing through a first opening at the proximal end of the shaft, wherein a proximal end of the pull element is coupled with the control element in the clearance space, forming a proximal connection, wherein the push tube extends from the proximal connection of the pull element with the control element through the first opening into the shaft, when the shaft is straightened, and wherein the push tube is arranged to fully cover a region of the pull element that is arranged in the clearance space of the interior of the housing when the pull element is maximally displaced in the proximal direction. |
