Abstract
An instrument holder including a releasably lockable adjustable arm for rigidly maintaining a tool or instrument in a pre-selected orientation. The instrument holder also includes a tensioning device pivotally connected by a hinge to the arm. The arm includes a plurality of links longitudinally arranged along a common axis, wherein adjacent links are pivotally connected by a hinge, and a duct. A tensioning cable extending within the duct of the arm attaches to the distal end of the articulated arm and to the tensioning device, and applies a tension force to compress the hinges so as to rigidly lock the arm into the preset position.
