ABSTRACT:
The invention relates to a holding arm system, particularly for holding surgical instruments in the region of an operation, with a holding arm incorporated into arm segments and into hinge joints connecting these. The holding arm at the proximal end is fastened to a rail which is guided in a horizontal position on the operating table. Each arm segment comprises straight-lined tube segments as outer sleeves and, in each arm tube, a shaft which is axially rotatable relative to the arm tube and which, with conical gearwheels on the end faces, engages into the shaft of the repective connecting arm segment. A fastening device is operable from a single arm segment and locks the whole holding arm by way of a braking device which engages at a defined location within the arm tube and by these means prevents the rotating of the shafts, connected with a positive fit, in the arm segments.
