A smoke evacuation flow regulator for use with a suction source to rapidly remove excess smoke during an endoscopic surgical procedure is described. The smoke evacuation regulator may include a body having a gas pathway and a knob assembly threadably attached to the body that is sized to completely open or completely close the gas pathway in a single revolution of the knob assembly. The head of the knob assembly may be sized and shaped to permit tactile determination of the rotational position of the knob assembly in low vision situations. The body of the smoke evacuation flow regulator may include a knob assembly retaining arm that cooperates with a disk or extension on the knob assembly to allow rotational freedom of the knob assembly, but prevent inadvertent removal of the knob assembly from the body during use.
