Abstract: The invention relates to a 3D input device (1) for controlling the position of an object (8, 14) in space, comprising a manually operable 3D input element (3), at which input element control demands in three spatial coordinates can be input, and a control dial (4), which generates an output signal dependent on the rotational angle when rotated. According to the invention, the 3D input device (1) comprises a control unit (21) which moves the object (8, 14) in space depending on the rotary movement executed at the control dial (4).

Abstract: The invention relates to an instrument (30) with an elongated first shaft (42), an end effector which is arranged on a distal end of the first shaft (42) and an actuation unit (19) arranged on the proximal end of the first shaft, wherein the actuation unit (19) comprises a first wheel (32) which is connected non-rotatably with the first shaft (42). The first shaft (42) is axially displaceable in relation to the first wheel (32) and is in threaded engagement with a second wheel (33) which is axially immovable in relation to the first wheel (32).

Abstract: The invention relates to a holding device (1) for a robotic surgical system, said holding device having a clamping device (11?) for removably holding a surgical object (12), said clamping device comprising at least two clamping jaws (14, 15) and a bearing part (8) on which at least one of the clamping jaws (10, 15) is movably mounted, and having at least one actuation element (18, 19) for actuating at least one of the clamping jaws (14, 15). The holding device (11) can be provided with a sterile encasement (13) in an intended use. According to the invention, the actuation element (18, 19) is guided in an axially movable manner on the bearing part (8).

Abstract: A friction brake (1) for braking a rail-guided transport device (26), in particular a lift (elevator), having at least one brake lever (15) with a brake lining (4), which can be pressed against a rail (2) in order to brake the transport device (26), and with an actuator (6) for actuating the at least one brake lever (15). According to the invention, a solid body joint (36) is proposed, which has at least one web (37) to which a brake lever (3) is fastened, wherein the web (37) twists about the longitudinal axis (38) thereof when the brake lever (3) performs a pivoting movement. Moreover, according to the invention, means (42, 42?, 50, 52) are provided, which limit or prevent deflection of the web (37) in the lateral direction (x).
