    摘要： A controller for a phacoemulsification system having a handpiece; an irrigation fluid source configured to supply an irrigation fluid to the eye; an aspiration source configured to aspirate the irrigation fluid from the eye through the handpiece; and a controller comprising a duration timer configured to provide a duration of an occlusion, the controller configured to: sense a value of an occlusion indicating parameter corresponding to an occlusion of the handpiece; measure a time since the occlusion of the handpiece; and control the aspiration source to the handpiece based at least in part on the measured time since the occlusion. The occlusion indicating_parameter may be a vacuum level, an irrigation flow rate, and/or an aspiration flow rate.

    摘要： A method for operating a surgical system including a control unit having a vacuum sensor and/or a flow rate sensor, the method including placing a handpiece in an operative relationship with an eye for a surgical procedure and thereafter supplying irrigation fluid to the handpiece while applying a vacuum to the handpiece to aspirate the irrigation fluid from the eye through the handpiece. During fluid aspiration, a vacuum level and/or flow rate is sensed which corresponds to an occlusion of the handpiece and from the sensed vacuum level and/or flow rate, a duration of the occlusion is determined. In response to the determined duration of occlusion, at least one of the handpiece parameters is varied.

    摘要： An apparatus and method for dispersing fluid from a fluid dispersal line is provided. The method comprises initiating operation of the medical apparatus, determining whether fluid has been dispersed from the medical apparatus via the fluid dispersal line since said initiating occurred, and assessing whether fluid is available in the fluid dispersal line. If fluid has not been dispersed from the medical apparatus since said initiating occurred and fluid is not available in the fluid dispersal line, the method includes distributing a commanded quantity of fluid plus an amount of fluid determined to fill the fluid dispersal line. Otherwise the method disperses only the commanded quantity of fluid.

    摘要： The invention relates to systems and methods for controlling vacuum within phacoemulsification systems. The phacoemulsification system may include a handpiece having a needle. The needle is coupled to a power source configured to cause the needle to be ultrasonically vibrated during operation and an aspiration source. The system further includes a footpedal that defines a first position and a second position. The system also includes a computer program product operatively coupled to the handpiece and the footpedal, the computer program product having a computer-usable medium having a sequence of instructions which, when executed by a processor, causes said processor to execute a process that controls power from the power source and vacuum from the aspiration source applied to the handpiece. The process includes the steps of providing a vacuum at a first level to the handpiece when the footpedal is at the first position; providing power to the handpiece when the footpedal is at the second position; and reducing the vacuum to a second level when the footpedal transitions from the first position to the second position.
