A movable arm (16,18) is provided for a surgical tray (10) that is connected to a surgical console, which is adjustable for height and allows for full, unlimited 360 DEG rotation of the tray. The arm mechanism (14) includes a movable wedge plate (42) containing a sloped or ramped depression that cooperates with one end of a motion transfer pin (48). 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 (16) on which a tray mount (22) is located to be raised and lowered via a position lockable gas spring (30). Such a construction allows the tray to be rotated a full 360 DEG without affecting the arm release mechanism. <IMAGE> |
