    摘要: Embodiments of the present invention provide an apparatus and method controlling the flow of aspiration fluid in an aspiration chamber of a surgical cassette. One embodiment of the present invention provides an aspiration chamber having an aspiration port positioned at or close to the bottom of the chamber. When the aspiration fluid enters the aspiration chamber from below the fluid surface (e.g., from a port located at the bottom or on a sidewall close to the bottom), it does not create disturbance at the liquid/air interface and thus does not disturb the continuous level sensing. Also, since the aspiration port is placed at or very close to the bottom of the aspiration chamber, the liquid inside the chamber can be fully used for sustained reflux and push priming.

    摘要: Embodiments of the present invention provide top and bottom clamping of a surgical cassette. One embodiment of the present invention includes a surgical cassette adapted for use in a surgical system having a first side (e.g., an inner side) and second side (e.g., an outer side). The surgical cassette, according to one embodiment, comprises a body portion configured to interface on its first side with a surgical console during use, a first clamping portion projecting from the top of the body portion configured to contact a first clamp rail on the cassette's second side during use and a second clamping portion projecting from the bottom of the body portion configured to contact a second clamp rail on the cassette's second side during use.

    摘要: In various embodiments, a pneumatic system valve for a surgical console may be controlled by a controller configured to adjust a valve duty cycle (VDC) of the valve to reduce a difference between the valve's differential pressure and a desired differential pressure. In some embodiments, average differential pressures may be detected and relayed from a pressure sensor, coupled to one or more ports of the valve, to the controller. The controller may compare the measured average differential pressure against the desired average differential pressure (e.g., received from the user). The controller may then determine a modified VDC to reduce a difference between the desired average differential pressure and the measured average differential pressure. In some embodiments, the desired average differential pressure may be determined based on input received from a user of the surgical console.
