A front surface of the piston rod (33) forms a third piston surface (54) which is larger than the first and second piston surfaces. The third piston surface (54) delimits the third operating chamber (53) of the hydraulic cylinder (23). The first and the second operating chambers (47, 48) are provided for controlling the position and/or the movement of the piston rod (33). The third operating chamber (53) serves to control the metal sheet clamping force of the drawing press via the piston rod (33).

Abstract: A fastening device for surgical holding systems includes a holding element and a fastening element with a ball joint, which can be locked by way of rotating an eccentric ring in the holding element. The joint socket defines a joint inner surface of the ball joint and the joint head a joint outer surface of the ball joint. When the eccentric ring clamps the joint head with respect to the joint socket, the position of three contact locations of the ball joint which lock the ball joint are unambiguously defined due to the shape of at least one of the three elements: joint socket, joint head and eccentric ring.
