Abstract
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.
