Abstract: An endodevice is disclosed with tension control. The endodevice includes a back end unit with an endoscopic unit coupled thereto. The back end unit includes first and second sensor elements, wherein the first sensor element is arranged between a drive member and a first spring element and the second sensor element is arranged between another end of the first spring element and a first tendon coupler. Each of the first and second sensor elements are configured to generate a sensor signal wherein the first sensor element, the second sensor element and the drive member are connected to a control unit. The control unit is configured to obtain sensor signals from the first sensor element and the second sensor element and to compute a deflection of the first spring element on the basis of the sensor signals obtained from the first sensor element and the second sensor element.
