A movable arm for a surgical tray that is connected to the surgical console, is adjustable for height and allows for full, unlimited 360° rotation of the tray. The arm mechanism includes a movable wedge plate containing a sloped or ramped depression that cooperates with one end of a motion transfer pin. Horizontal movement of the wedge plate causes vertical movement of the pin. The other end of the pin, opposite the wedge plate, actuates a release mechanism that allows the arm on which the tray is mounted to be raised and lowered via a pressurized gas cylinder. Such a construction allows the tray to be rotated a full 360° without affecting the arm release mechanism.
