    摘要: A system for detecting intraocular pressure events during phacoemulsification surgery having a surgical console, a handpiece having a proximal end being communicatively connected to an irrigation line and an aspiration line; a first sensor in communication with the aspiration line or the irrigation line for providing a first measurement value; and a second sensor in communication with the aspiration line for providing a second measurement value; and wherein at least one characteristic of the irrigation fluid or aspiration fluid in their respective lines is changed in accordance with the difference between the first measurement value and the second measurement value. A system for calibrating patient eye level and wound leakage; detecting occlusion or post occlusion surge; determining BSS usage or remaining in a container; and detecting a fluid line abnormality using a first sensor and a second sensor in different configurations and differences in first and second measurement values.

    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.

    摘要: A medical system includes a medical instrument including an irrigation and aspiration channel to carry irrigation fluid to, and remove aspirated matter from, a distal end of the medical instrument, a reservoir to store the irrigation fluid, a receptacle to collect the aspirated matter, and a vane pump including a pump housing having an inner surface around a pumping chamber, the pump housing including irrigation inlet and outlet ports coupled to the pumping chamber and respectively connected to the reservoir and the irrigation channel, and aspiration inlet and outlet ports coupled to the pumping chamber and respectively connected to the aspiration channel and the receptacle, and wherein the vane pump is configured to simultaneously pump via the pumping chamber, at substantially the same flow rate, the irrigation fluid from the reservoir to the distal end and the aspirated matter from the distal end to the receptacle.
