Abstract:
1. A suction limiting device with variable control for use in a surgical system, the device comprising: a main vent body having a fluid carrying bore extending therethrough from a first end to a second end; 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; and a valve disposed within the main vent body and positionable between an open position when negative pressure exists in the main vent body and a closed position when a positive pressure state exists in the main vent body, wherein in the closed position, the valve prevents fluid flow from the fluid carrying bore into the vent mechanism, wherein the vent mechanism includes: a cap member that has the main vent opening formed therethrough, the cap member being positioned relative to a vent housing section of the main vent body so that the main vent opening is the only entrance into the fluid carrying bore by passing through the vent housing section; and a switch that is rotatably and interlockingly coupled to the vent housing section with the cap member disposed between the switch and the vent housing section, the switch having a vent port formed therein, the switch being positioned between a fully open position where the vent port is in complete registration with the main vent opening and a fully closed position where the vent port is off set from the main vent opening.
