  • Ophthalmic microsurgical system employing surgical module employing flash EEPROM and reprogrammable modules
    Patent number: 6251113
    Abstract: A system for controlling a plurality of ophthalmic microsurgical instruments connected thereto. The microsurgical instruments are for use by a user such as a surgeon in performing ophthalmic surgical procedures. The system includes a data communications bus and a user interface connected to the data communications bus. The user interface provides information to the user and receives information from the user which is representative of operating parameters of the microsurgical instruments. The system also includes surgical modules connected to and controlling the microsurgical instruments as a function of at least one of the operating parameters. The surgical modules are also connected to the data communications bus. The data communications bus provides communication of data representative of the operating parameters between the user interface and the surgical modules.

  • Detection of ophthalmic surgical handpiece by injecting current signal
    Patent number: 5991142
    Abstract: An apparatus to detect the presence of a surgical handpiece is provided. The handpiece is electrically isolated from its source of electric power by a transformer having two primary windings and one secondary winding. The first winding provides power to the handpiece and the second winding is used in the handpiece detection apparatus. The handpiece detection apparatus includes a detection circuit and a comparator that compares the electrical signal input to a standard to determine the presence of the handpiece.

  • Fluid collection cassette identification scheme
    Patent number: 5718238
    Abstract: 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.
