    摘要： An ophthalmic surgical device (10) includes a housing (12) having a distal end (14) and a proximal end (16). A cannula (18) is attached to the housing distal end (14) and has a distal tip (20) with at least one port (22) in communication with a lumen (19) extending through the cannula (18) and in communication with an aspiration path (24) in the housing (12). A vibration source (26) is held within the housing (12) for vibrating the distal tip (20) for assisting in vitreous and other tissue removal. An aspiration source (152) connected to the aspiration path (24) for applying a negative pressure to the lumen (19) and the at least one port (22) for removing fluids and the vitreous and other tissue from the eye. The vibration source (26) and the aspiration source (152) together create a periodic bi-directional flow of tissue through the port (22) without creating cavitation externally of the distal tip (20).

    摘要： The present invention provides a phacoemulsification needle having an improved distal tip. The distal tip is provided with a generally rounded closed distal end having a plurality of longitudinally extending ports provided therein communicating between the interior lumen of the needle and exteriorly of the needle. The outer surface of the distal end is rounded to provide a smooth surface so as to not cut or snag an eye tissue. Two embodiments of the phacoemulsification needles are shown having five and nine ports therethrough, respectively.

    摘要： The invention is a method of identifying whether a particular fluid collection cassette is designated to have a particular use, such as posterior surgery or anterior surgery. A reflux bulb attached to a fluid collection cassette has a material disposed on or in said reflux bulb in a predetermined location. When the reflux bulb is disposed on the fluid collection cassette, and the fluid collection cassette inserted into a housing, a sensor attached to the housing senses the existence, or non-existence of the material and sends a signal conveying the information to a main controller.
