Abstract: A surgical cassette for an ophthalmic surgical system includes an irrigation system, an aspiration system, and a computer. The irrigation system is in fluid communication with a handpiece and carries fluid toward a surgical site. The aspiration system is in fluid communication with the handpiece via an aspiration conduit and carries fluid away from the surgical site. The computer instructs the aspiration system to vibrate fluid back and forth within the aspiration conduit to perform a priming procedure.

Abstract: According to certain embodiments, a surgical cassette for an ophthalmic surgical system comprises an irrigation conduit that is in fluid communication with a handpiece and carries fluid toward a surgical site. An aspiration conduit is in fluid communication with the handpiece and carries fluid away from the surgical site. An aspiration pump creates a vacuum pressure in the aspiration conduit to draw fluid through the aspiration conduit towards a drain reservoir. A reservoir couples with a pressure-vacuum source to manage the reservoir pressure. A valve is in fluid communication with the aspiration conduit and the reservoir, and provides one or more channels between the aspiration conduit and the reservoir. Each sensor detects a pressure associated with the surgical site. A computer controls the valve in response to the pressure detected by the one or more pressure sensors to mitigate a pressure or volume change.

Abstract: An ultrasonic cutting tip has a hollow shaft with a proximal and distal end. The proximal end is configured to be attached to an ultrasonic hand piece, and the distal end has a smooth continuous surface. An opening is located near the distal end of the hollow shaft. The opening is configured to cut vitreous when the cutting tip is vibrated ultrasonically in a torsional manner.

Abstract: A surgical cassette for an ophthalmic surgical system comprises an irrigation system and an aspiration system. The irrigation system is in fluid communication with a handpiece and carries fluid toward a surgical site. The aspiration system is in fluid communication with the handpiece via an aspiration conduit, and carries fluid away from the surgical site. The aspiration system comprises a chamber that expands to store fluid, and collapses to move the fluid to meet a volume demand in the aspiration conduit to mitigate a post-occlusion break surge.

Abstract: A surgical cassette for an ophthalmic surgical system includes an irrigation system and an aspiration system. The irrigation system is in fluid communication with a handpiece and carries fluid toward a surgical site. The aspiration system is in fluid communication with the handpiece and carries fluid away from the surgical site. The aspiration system includes an aspiration pump and tubing of an aspiration conduit. The aspiration pump generates a normal vacuum pressure within the aspiration conduit to carry fluid away from the surgical site during normal operation. The tubing has a larger cross-sectional area in response to normal vacuum pressure. The tubing collapses from the larger cross-sectional area to a smaller cross-sectional area in response to an occlusion; maintains the smaller cross-sectional area during a post-occlusion break surge to mitigate the post-occlusion break surge; and returns to the larger cross-sectional area after the post-occlusion break surge.
