摘要： An apparatus and method of detecting an interchangeable tip of a handpiece of an ocular surgical system is disclosed. The interchangeable tip of the system includes an irrigation port that receives fluid flowing from an irrigation source and an aspiration port that removes or aspirates fluid and/or materials from the surgical field, in particular a patient's eye, through use of an aspiration source or pump. The method comprises attaching the interchangeable tip to the handpiece, introducing fluid flow into the system and determining the fluid flow rate of fluid flow in the system, determining the pressure of fluid flowing into the interchangeable tip, determining the pressure of fluid flowing out of the interchangeable tip and comparing the flow rate and pressure information to known flow rate and pressure readings of known types of interchangeable tips to determine the type of interchangeable tip being used.

摘要： A vitrectomy apparatus is provided, including a pressure source, a cut valve connected to the pressure source, the cut valve configured to be turned on and off to provide pressure to selectively extend and retract a vitrectomy cutting device, a sensor configured to sense pressure provided from the cut valve, and a controller configured to control operation of the cut valve based on pressure sensed by the sensor.

摘要： A handpiece for ocular surgery that includes a handle having at least inlets for irrigation and aspiration; a sleeve extending distally from a first end of the handle, wherein the sleeve comprises a bore extending a length of the sleeve along a central axis of the sleeve, and includes at least one port suitable to deliver irrigation from the irrigation inlet substantially distal from the first end of the handle; the aspiration being provided between an aspiration inlet and a distal bore port; a motor coupled with a second end of the handle and having a shaft; and an auger associated with the shaft, and extending at least partially through an interior portion of the handle between the second and the first ends and extending along the length of the sleeve, wherein a tip of the auger distal to the shaft is advanced by actuation of the motor.
