Abstract
A force compensating device includes a force generating unit configured for generating a compensating force that at least partially counteracts a tractive force acting on the force compensating device. The device includes at least one safety unit that is rotatable about a first axis of rotation and which, in the event of a malfunction of the force generating unit, can be moved by the force generating unit from an operating position to a locked position. The safety unit includes a first element and a second element that are rotatably connected to each other at a second axis of rotation, and at least one locking unit that blocks rotational movement of the safety unit from the locked position back to the operating position when the safety unit has been triggered due to a malfunction. A two-part safety unit in combination with the locking unit allows the safety unit to trigger and remain triggered in all fault situations. The force compensating device may be used in a medical system.
