Abstract
An operating table comprises a patient rest or support structure which is mounted at a rolling bearing, i.e. a bearing associated with the rolling motion of the patient rest or support structure. The axis of this rolling bearing corresponds with a rolling or roll axis and defines a predetermined angle with the patient rest or support structure, so that the extension of the axis of the rolling bearing, subsequent to intersection thereof with the plane of the patient rest or support structure at a predetermined punctiform location, extends substantially through the center of an operating site defined in or at the head of a patient stretched out on the patient rest or support structure. In this manner, it is rendered possible that, when rolling movements or motions with the patient rest or support structure are accomplished by means of a suitable drive for such rolling motion, the center of the operating site remains essentially unchanged at the same location. By virture of this arrangement of the rolling or roll axis, the expenditure for adjusting means and mechanisms for the rolling or pivotal movement of the patient rest or support structure is considerably reduced.
