摘要： A suction limiting device with variable control for use in a surgical system includes a main vent body having a fluid carrying bore extending therethrough and a variable vent mechanism having a main vent opening in selective fluid communication with the fluid carrying bore so as to permit introduction of atmospheric air into the fluid carrying bore. The vent mechanism being adjustable so that the degree of airflow into the fluid carrying bore is variable between a fully open position to a fully closed position where atmospheric air is prevented from entering the fluid carrying bore. The suction limiting device also includes a valve disposed within the main vent body and positionable between an open position when negative pressure and a closed position when positive pressure exists in the main vent body.
