Abstract: Embodiments disclosed herein provide a connection detecting system for a surgical console. The connection detection system comprises a port for receiving a connector of a surgical device, an emitter, a detector, and a controller connected to the emitter and the detector. The port comprises a light transmission system comprising a detection zone through which the connector of the surgical device is configured to be disposed when the surgical device is coupled to the surgical console, and a pair of light pipes disposed at opposite ends of the detection zone. The emitter is configured to generate a light for propagation through the light transmission system, and the detector is configured to detect the light propagated through the light transmission system. The controller is configured to determine whether the surgical device is connected to the port based on whether the light is detected by the detector.

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.
