    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.

    摘要： A method of determining the accuracy of a pressure sensor in a surgical console is disclosed. The method involves actuating a linear actuator so that its plunger is linearly displaced a pre-defined amount, and measuring the force exerted by the plunger on a non-compliant member. The accuracy of the linear actuator and the plunger are determined by comparing the force measured in the measuring step to a pre-defined force.

    摘要： A pressure sensing chamber having a tubing extension with a reduced diameter portion extending through the chamber. The tubing contains a plurality of ports so as to allow the purging of air from the chamber, but the ports are sized so that bubbles entering the tubing cannot easily flow into the chamber. The reduced diameter portion creates a pressure differential between the holes. This differential pressure creates flow through the chamber under high liquid flow and turbulent liquid flow events.

    摘要： An infusion control system having a flexible, collapsible infusion container. The container can be compressed between rollers or plate so at to pressurize the container. Such a system allows for rapid pressure response rates without the need of venting devices or air filtering. The may also include an irrigation flow sensor. The sensor may be placed in the control console or in the infusion handpiece. Irrigation flow measurements provided by the sensor allows the control system to vary irrigation pressure and/or flow, aspiration pressure and/or flow and power supplied to the handpiece more accurately than sensors that monitor aspiration flow.
