Abstract: A carrier arm joint device for a carrier arm of a stand device for arranging in the operating room and for displacing a medical device held on the carrier arm is configured for setting a payload corresponding to a weight of the medical device to be taken up by the carrier arm. The device includes at least one pivot axis for mounting at least one strut of the carrier arm, respectively; and a support axis for supporting a lever configured to transmit forces holding the carrier arm between the strut and the carrier arm joint device A distance between the axes is adjustable within an adjustment range in order to set the payload; the size and/or the extent of the adjustment range is independent of the position of the pivot axis. It is possible to maximize the adjustment range and therefore the payload spectrum in a comparatively compact and structurally rigid joint. A carrier system and a stand device can include at least one such carrier arm joint device.

Abstract: A carry system or a medical ceiling support for carrying or supporting medical-technical devices in a hospital treatment room. The ceiling support is provided with at least one extension or arm arranged substantially horizontally and at least one supporting column; at least one pivot joint and/or at least one lifting and lowering device; a support head mounted at the extension or arm for reception of the medical-technical devices; and an operating aid with at least one operating element for releasing or operating a respective brake in the at least one pivot joint or for operating the at least one lifting and lowering device. The ceiling support is arranged for generation of a feedback or back coupling which identifies or characterizes the respective brake or lifting and lowering device operated by the operating aid for a user locally at the support.
