Patent ID: 8382048

Claim:
Surgical holding arm, comprising: a plurality of holding arm members coupled to one another, a tensioning device for tensioning the holding arm members against one another, the tensioning device comprising a tensioning element passing through the holding arm members, a tensioning member coupled to a proximal end of the tensioning element, and a proximal tensioning part, the tensioning member adapted to be rotated about an axis of rotation extending perpendicular to a longitudinal axis of the tensioning element, and a movement limiting device for limiting movement of the tensioning member relative to the proximal tensioning part, the movement limiting device comprising a least one stop for interacting with correspondingly designed stop surfaces on the tensioning member for defining at least one of an operative position, an adjusting position, and a cleaning position when in contact with the tensioning member, wherein: the tensioning member is eccentrically coupled with respect to the axis of rotation to the proximal end of the tensioning element, the tensioning device is designed in such a manner that the holding arm is adapted to be brought from said operative position, the holding arm members being tensioned against one another so as to be immovable in said operative position, into said adjusting position via rotation of the tensioning member of less than 360 degrees, the holding arm members being movable relative to one another in said adjusting position, the holding arm is adapted, in addition, to be brought into said cleaning position via the rotation of the tensioning member of less than 360 degrees, adjacent holding arm members being movable away from one another further in said cleaning position than in the adjusting position; and the movement limiting device is designed in such a manner that in a first limiting position the tensioning member is adapted to be brought from the operative position into the adjusting position and vice versa.
