  • Patent number: 11796084
    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.

  • Publication number: 20210213183
    Abstract: Control methods for generating a venturi vacuum in a substantially oscillation-free manner for a surgical system. The control methods generally include utilizing real-time readings from a venturi vacuum generator inlet pressure transducer and a vacuum pressure transducer on the vacuum side of the venturi vacuum generator. These values may be employed in real-time to ascertain the emergence of an oscillation region on the vacuum side which may then be addressed by way of a bleed control proportional valve. When employed in combination with a throttle control proportional valve at the inlet side of the venturi vacuum generator, pressures may be manipulated in light of one another and/or individually as directed through a central controller. Thus, the presentation of oscillations on the vacuum side may be avoided to provide for a more stable vacuum supported surgical procedure.

  • Publication number: 20210173191
    Abstract: The present disclosure provides a system for active vibration reduction of a surgical microscope. The system includes a surgical microscope with an optical head connected to a control device that adjusts the position of the optical head in any of the X, Y, and Z-directions. The system also includes a processor and an accelerometer that detects motion of the optical head and generates data relating to the motion. The disclosure also provides a method for active vibration reduction, which includes receiving data relating to motion of an optical head of a surgical microscope, determining whether the motion is a vibration event or an intentional movement, determining a distance and direction the optical head must be adjusted to reduce the vibration caused by the motion detected, and generating and transmitting a control signal to adjust the position of the optical head to reduce the vibration of the vibration event.

  • Patent number: 9937077
    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.
