    摘要： A method of testing a surgical system that takes advantage of the fact that in a balanced irrigation/aspiration system (inflow≧outflow) the duration of the aspiration pressure recovery to the irrigation fluid source pressure immediately following pump stop is independent of pump run time. This method provides a more reliable way of detecting restricted irrigation flow configurations not detectable by the current methods, such as marginal irrigation flow cases that could potentially lead to surgical complications (e.g. chamber collapse during post-occlusion break surge).

    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： A surgical system that is able to sense the onset of an occlusion or other surgical event as well as the instant an occlusion breaks. To help avoid overheating of the tip, the system determines a temperature of an eye using irrigation flow rate and reduces the power to the handpiece automatically if an overheating situation is predicted. Alternatively or in addition, the system monitors the power drawn by the handpiece, which is indicative of the cutting load on the tip, and automatically adjusts the power or stroke of the tip to compensate for increased loads on the tip.
