Abstract: An ophthalmic irrigator-aspirator has a handpiece with aspiration and irrigation openings through its distal end; and a narrow aspiration tip projecting distally. A flexible sleeve has an annular hub for watertight connection to the handpiece. The sleeve surrounds the full extent of the tip. An intermediate portion of the sleeve forms a channel for an irrigation fluid along the exterior of the tip to a port in the sleeve. The distal end of the sleeve is sized for a watertight connection over the distal portion of the tip. Such distal end of the sleeve has an aspiration port in communication with the tip aspiration port. The sleeve proximate, intermediate, and distal portions are integral with each other and are formed of a resilient material that allows the sleeve to be manually stretched onto the handpiece and tip.

Abstract: A cover that protects a tip of a surgical instrument. The tip can be placed within a housing of the cover. The housing has openings on each end that allow sterilization fluid to flow across the tip during an autoclave procedure. The tip can be placed on a handle of the cover. The handle can be rotated relative to the housing to allow for the easy insertion and removal of the tip from the cover.

Abstract: An elongated, rigid cannula has a peripheral wall defining a central bore and a side port for introduction of material into the bore. A covering of resilient, flexible material is provided in the area of the side port, with a corresponding aperture aligned with the port of the cannula. The aperture of the resilient covering can be somewhat smaller than the underlying cannula port, forming a resilient margin that overhangs and surrounds the port.

Abstract: A medical instrument includes a handpiece having irrigation and aspiration channels, a connector coupled to the handpiece by a sliding friction fit and having channels forming continuations of the irrigation and aspiration channels, and a removable tip threadedly coupled to the connector.

Abstract: An apparatus for controllably delivering an IOL into the eye of a patient is disclosed. The device is configured for convenient and reliable positioning of a plunger rod assembly at different stages of the IOL injection procedure, such that various aspects of the insertion procedure can be performed precisely and reliably by a user of the device. The present invention may include a latch pin and a latch finger configured for engagement with the latch pin to prevent proximal lateral movement of the plunger rod assembly so that the intra-ocular lens may be accurately positioned within the eye. The device assists the user during the procedure by accurately and consistently positioning the plunger rod assembly prior to ejection of the folded or rolled IOL from the insertion device.

Abstract: A passage for irrigation liquid extends lengthwise along the exterior surface of the body of a phacoemulsifier handpiece and is formed between an outer arcuate section and the exterior surface of the body itself. The passage is of noncircular cross section so that it protrudes from the body, but to a lesser degree than a circular conduit having the same cross-sectional area.

Abstract: The outer cannula of an ophthalmic irrigator-aspirator has rigid tip and butt sections and a more flexible central section. The central section can be an elastomeric sleeve that extends between the tip and butt sections. The outer cannula includes reinforcement members that prevent the elastomeric sleeve from becoming completely closed by compression caused by a tight fit in an incision in a patient's cornea. The reinforcement members may be rigid or somewhat flexible.
