A rail-mountable support assembly includes a universal positioning arm for holding a surgical instrument such as an endoscope or retractor during a surgical procedure. Coarse adjustment of instrument X-Y position across the sterile field above an operating table is provided by an articulated arm which is rotatably coupled to an upright support shaft. Fine adjustment of surgical instrument elevation above the operating table is provided by a reversible drive motor which extends and retracts the instrument along the longitudinal axis of the support arm. The insertion orientation of the instrument is adjustable by a rotatable coupling. Release of the articulated arm for coarse positioning can be performed manually by actuation of an arm-mounted switch, and fine positioning can be performed manually by arm-mounted switches or by foot pressure applied to floor switches by the surgeon.

Surgical instrument support apparatus comprising, in combination: a rail clamp assembly adapted for releasable attachment to the side rail of an operating table; an upright support shaft coupled to the rail clamp assembly for rotation relative to the rail clamp assembly; a support arm assembly coupled to the upright support shaft for holding a surgical instrument during a surgical procedure, the support arm assembly including a proximal support arm and a distal support arm which are movably coupled together for folding movement relative to each other; first means coupled between the distal support arm and the rail clamp assembly for adjusting the elevation of the distal support arm relative to the rail clamp assembly; second means coupled between the proximal support arm and the distal support arm for adjusting the angular displacement of the distal support arm with respect to the proximal support arm; and, third means coupled between the rail clamp assembly and the upright support shaft for selectively holding the upright support shaft in a fixed rotational position relative to the rail clamp assembly, and for selectively releasing the upright support shaft so that it can be moved to a different rotational position relative to the rail clamp assembly.
