    摘要： In various embodiments, a surgical cassette, configured to engage peristaltic pump rollers, may include two or more pump segments between a sheet and a substrate coupled to the sheet. The two or more pump segments on the cassette may produce additional flow (e.g., approximately twice the flow for two segments as opposed to one) than if the cassette had only one pump segment engaging the roller. Further, in some embodiments, the two or more pump segments and rollers on the roller head may be configured to provide a flow profile in which a peak of a pulse from a first pump segment is at least partially out of phase with a peak of a pulse from the second pump segment. The combined resultant flow may then have a flow profile with pulsation amplitudes that are smaller than the individual pump segment pulsation amplitudes.

    摘要： An assembly for a phacoemulsification surgical system includes an aspiration system arranged to aspirate fluid from a surgical site. The aspiration system includes an aspiration path within the phacoemulsification hand piece and includes a flexible small bore aspiration tubing in fluid communication with the aspiration path. The small bore aspiration tubing has a nominal inner diameter smaller than about 0.050 inch to reduce levels of occlusion surge within the surgical system. A high-output, peristaltic pump communicates with the small bore aspiration tubing and is operable to create a flow through the small bore aspiration tubing.

    摘要： A surgical system having a cassette with an aspirant collection chamber and an aspiration vent line that draws fluid from the aspirant collection chamber. The pressure within the collection chamber is maintained near ambient so that when the aspiration vent line is open, fluid flows from the collection chamber and into the aspiration line. Such a system does not require a second source of irrigation fluid, minimizes pressure surges into the irrigation fluid line and does not affect the fluidic performance of the aspiration system. In addition, various vent pressures can be achieved by varying the vertical position of the reservoir relative to the aspiration line.
