ABSTRACT:
An overhead arm assembly particularly suited for selectively positioning ultrasonic medical diagnostic equipment. The assembly is comprised of three interconnected pivot arms having both dynamic and static counterweights and arranged so that the outermost or third arm is always vertically oriented. A work element manipulation assembly is rotatably mounted to the third arm adjacent the distal end thereof and a scan arm assembly is mounted to the manipulation assembly. The manipulation assembly includes means for setting the angular orientation of a plane in which the scan arm assembly is constrained and means for selectively shifting the scan arm assembly to other, parallel planes of constraint. The scan arm assembly is dynamically counterweighted and is comprised of pivotally interconnected scan arms which carry a work element such as an ultrasonic transducer.
