Abstract
An articulated arm for holding surgical instruments, having elongated arm members; rotational joints connecting the arm members end to end, such that members are pivotable about the joints and at least one of the joints is selectively lockable by fluid pressure; and a plurality of tubes communicating fluid pressure between two adjacent joints. When two adjacent members are pivoted relative to one another, the tubes connecting a particular pair of joints remains substantially stationary with respect to the arm member connecting that pair of joints.
