A surgical suction nozzle for removing surgical debris and vomitus from unconscious patients in a surgical operative field that is highly resistant to clogging. An oval-shaped opening forming the suction tip is circumscribed by a raised ridge inward of the opening. A plurality of small apertures inward of the raised ridge circumscribes the nozzle, which is placed into the mouth during surgery. The suction nozzle is angularly related in three cylindrical segments to prevent any encumbrance to the surgeon. A suction control hole located on the medial segment of the suction nozzle allows the surgeon to control the suction pressure during the operation. The proximal end of the suction nozzle is beveled to be connected to a suction tube which transports surgical debris to a vacuum collection jar via a suction pipe in the cap of the jar. A debris removal pipe in the cap of the jar is connected to a vacuum tube leading to the vacuum line service outlet found in the surgery room.
