Abstract: Embodiments disclosed herein provide a surgical cassette including a housing having a base and a cover coupled to the base, wherein the cover and the base each at least partially define one or more channels. The housing further includes a plurality of ports formed in the base and in fluid communication with at least one of the one or more channels, a plurality of bores formed in the base and configured to receive one of a plurality of valve assemblies, and at least one pump landing formed in the base and configured to receive at least one pump assembly. A plurality of valve assemblies is disposed within the plurality of bores and configured to control fluid flow in the one or more channels of the housing. At least one pump assembly is disposed within the at least one pump landing and configured to provide a source of pressure or vacuum to the one or more channels of the housing.

Abstract: Embodiments disclosed herein provide a surgical console, a surgical cassette, and a method for utilizing an image sensor to acquire grayscale image(s) and an embedded microcontroller to then process the image(s) to decode the barcode and/or determine the current level of fluid within the surgical cassette. The image sensor is utilized to detect external light that comes into the field of view of the image sensor. A software algorithm stored within a microcontroller in the surgical console determines whether the potential is high for external light interference. If there is a high potential for external light interference, an advisory or alarm is generated to warn the user to remove the external light source or to turn the console away from the external light source. Once the user has removed the external light and then cleared the advisory, normal console operations and functions can resume.

Abstract: Embodiments disclosed herein provide a surgical cassette including pump assemblies with improved contact between a displacement sensor disposed within a surgical console and a diaphragm disposed within the surgical cassette. Each pump assembly includes a diaphragm retainer ring that provides a sufficient creepage and clearance margin, acts as a lead-in for the displacement sensor, assists in preventing misalignment, and provides robustness for the ultrasonic welding process which couples the diaphragm retainer ring to the surgical console. The diaphragm retainer ring is impregnated with a lubricant so to facilitate seating of the displacement sensor with the cassette. A cantilever portion of the diaphragm retainer ring increases a creepage and clearance margin, as well as increases overall part strength in the event of a collision with the displacement sensor and during ultrasonic welding. An insulator is also provided that further increases the creepage and clearance margin.
