Abstract: A positioner or manipulator for an endoscope, laparoscope, or other surgical instrument, includes a flexible arm having a base attached to an operating table. A drape joint at the upper end of the arm has a tubular sterile drape which is pulled back over the arm, to provide a sterile field around the arm. A scope ring adapted to hold a scope or other instrument attaches to the drape joint. The attachments between the scope ring, drape joint and arm are preferably made with quick release fittings. The need to sterilize the arm is removed, decreases hospital operation costs, and increasing the level of sterility.
