    Abstract: Certain embodiments provide a cover mounted on top of a manifold, the cover comprising an exhaust opening and an inner surface forming a space between the inner surface of the cover and an outer surface of the manifold, wherein the space is configured to receive pressurized gas at an inlet positioned on a first side of a valve. The valve is coupled to the outer surface of the manifold and positioned within the space. The exhaust opening is positioned on a second side of the valve opposite the first side of the valve such that pressurized gas circulates from the inlet around the valve and exits through the exhaust opening.

    Abstract: In various embodiments, a surgical console may include a pneumatic valve to drive a pneumatic tool coupled to the surgical console. The console may further include a controller operable to control and adjust the valve open/close cycle times according to a valve duty cycle. The valve may switch between ports (valve open time for a first port and valve close time for a second port) such that a total valve time may approximately equal the valve open time plus the valve close time. The valve duty cycle may indicate a percentage of the total valve time for the controller to signal the valve to open and may include an adjustment that corresponds to a signal timing of the open and/or closed valve positions that will result in open and closed operating pressures above a predetermined threshold.

    Abstract: Interruptor de pie quirúrgico (10) que comprende: a) una base (12) que presenta un fondo (85); b) un pedal (14) montado a la base; caracterizado porque el interruptor de pie comprende además: c) una pluralidad de émbolos (86) montados en el interior de la base de manera que puedan retraerse, y d) un material de fricción relativamente alta (84) montado al fondo de la base, en el que los émbolos se retraen en el interior de la base cuando se coloca peso en el interruptor de pie y se extienden hacia el exterior desde la base y desde el material de fricción relativamente alta cuando no se coloca peso en el interruptor de pie.
