A surgical instrument support assembly includes a rail-mounted clamp and a universal positioning arm for holding a surgical instrument such as an endoscope or retractor at a fixed position over an operating table during a surgical procedure. Coarse adjustment of instru- ment X-Y position across the sterile field is provided by an articulated arm assembly which is rotatably coupled to the rail-mounted clamp. Fine adjustment of surgical instrument elevation above the operating table is provided by a reversible drive motor which extends and retracts the surgical instrument along the longitudinal axis of an extendable support arm. Coarse X-Y positioning of the articulated arm assembly can be performed manually upon actuation of an arm-mounted switch, and fine adjustment of elevation is performed upon actuation of arm-mounted switches or by foot pressure applied by the surgeon to floor switches.
