Abstract:
1. A device for supporting at least one arm of an operating person during a surgical or medical operation, comprising: at least one supporting element for supporting said at least one arm of said operating person, a carrying structure for carrying said supporting element at which said supporting element is arranged, said carrying structure being configured such that said at least one supporting element can be lowered or raised for adjusting a height of said operating person's arm, said carrying structure having at least one carrying arm which is pivotable about at least one at least approximately horizontal pivot axis such that pivoting of said carrying arm raises or lowers said at least one supporting element, and said carrying structure comprising a mechanical control system acting on the pivotability of said at least one carrying arm in the upward direction differently from the downward direction, wherein said control system imposes a first friction to said pivotability in said upward direction and a second friction to said pivotability in said downward direction, wherein said second friction is higher than said first friction.
