Publication number: 20210213183Abstract: 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.Type: ApplicationFiled: January 12, 2021Publication date: July 15, 2021Inventor: Jiansheng Zhou

Patent number: 9937077Abstract: 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.Type: GrantFiled: July 8, 2014Date of Patent: April 10, 2018Assignee: Alcon Research, Ltd.Inventors: Jiansheng Zhou, Kurt D.
