Abstract
A tool holding and positioning device for remote operation through a narrow opening is described. The tool holding and positioning device has a proximal end, an elongated first tubular member extending from the proximal end, and a distal end. A second tubular member is attached to the first tubular member for rotation about a fixed point adjacent the distal end thereof to position the second tubular member in a particular angle with respect to the longitudinal axis of the first tubular member. A first rod or cable is connected between the proximal end and the second tubular member for controlling its angular position with respect to the longitudinal axis. A second rod or cable is extended from the proximal end through the first and second tubular members to support and position tool means at a variable distance from the fixed point. The tool means are operatively connected to the second rod or cable and are controlled by control means operated from the proximal end.
