20100036406 | Method of Controlling a Surgical System Based on a Load on the Cutting Tip of a Handpiece - A surgical system that is able to sense the onset of an occlusion or other surgical event as well as the instant an occlusion breaks. To help avoid overheating of the tip, the system determines an approximate temperature of the eye using an irrigation flow rate and reduces the power to the handpiece automatically if an overheating situation is predicted. Alternatively or in addition, the system monitors the power drawn by the handpiece, which is indicative of the cutting load on the tip, and automatically adjusts the power or stroke of the tip to compensate for increased loads on the tip. | 02-11-2010 |
20100130914 | Method Of Controlling A Surgical System Based On Irrigation Flow - A surgical system that is able to sense the onset of an occlusion or other surgical event as well as the instant an occlusion breaks. To help avoid overheating of the tip, the system determines a temperature of an eye using irrigation flow rate and reduces the power to the handpiece automatically if an overheating situation is predicted. Alternatively or in addition, the system monitors the power drawn by the handpiece, which is indicative of the cutting load on the tip, and automatically adjusts the power or stroke of the tip to compensate for increased loads on the tip. | 05-27-2010 |
20110015563 | Method Of Controlling A Surgical System Based On A Rate Of Change Of An Operating Parameter - A surgical system that is able to sense the onset of an occlusion or other surgical event as well as when an occlusion breaks. To help avoid overheating of the tip, the system of the present invention predicts the temperature of the eye using irrigation flow rate and reduces the power to the handpiece automatically if an overheating situation is predicted. Alternatively or in addition, the system of the present invention monitors the power drawn by the handpiece, which is indicative of the cutting load on the tip, and automatically adjusts the power or stroke of the tip to compensate for increased loads on the tip. | 01-20-2011 |
20110148304 | THERMOELECTRIC COOLING FOR INCREASED BRIGHTNESS IN A WHITE LIGHT L.E.D. ILLUMINATOR - A white light source includes a light-emitting diode configured to emit light of a characteristic wavelength. The white light source also includes at least one phosphor. The phosphor is configured to emit light in response to the light emitted by the light-emitting diode so that the white light source emits white light. The white light source further includes a thermally conductive base in thermal contact with the light-emitting diode and a thermo-electric cooler in thermal contact with the thermally conductive base. | 06-23-2011 |
20110232358 | Surgical Cassette - A surgical system and cassette, the cassette having an identification method that is specific to the cassette. Suitable methods include bar coding or Radio Frequency Identification (“RFID”). Cassette information that may be encoded include features such as lot number and performance characteristics, such as pressure sensor calibration data, flow and pressure data and any other performance characteristics of the cassette captured during testing of the cassette at manufacture. | 09-29-2011 |
20110257638 | DISPLAY FOR OPHTHALMIC SURGICAL CONSOLE WITH USER-SELECTABLE SECTORS - An ophthalmic surgical system includes a display device and a user interface. The display device generates a display on an image of a patient's eye comprising a plurality of non-overlapping display sectors. Each display sector displays one of a plurality of user-selectable surgical parameters. A user interface receives a user selection of one or more of the user-selectable surgical parameters to be displayed. | 10-20-2011 |
20110313343 | Phacoemulsification Fluidics System Having a Single Pump Head - A phacoemulsification fluidics system for irrigating and aspirating a surgical site includes a sterile solution reservoir, an irrigation path configured to extend from the sterile solution reservoir to the surgical site, and an aspiration path configured to extend from the surgical site. The system also includes a single flow control pump head associated with both the irrigation path and the aspiration path. The flow control pump head is arranged within the system to simultaneously pressurize the irrigation path in a manner that drives the irrigation fluid to the surgical site and pressurize the aspiration path in a manner that vacuums waste fluid from the surgical site. | 12-22-2011 |

20130012868 | Vacuum Level Control of Power For Phacoemulsification Hand Piece - The present invention comprises a method of operating an ophthalmic surgical hand piece, providing a series of power pulses to the hand piece, each of the series of power pulses having a first portion that produces torsional movement of a cutting tip and a second portion that produces longitudinal movement of the cutting tip; measuring vacuum pressure; altering the duration of the first portion as vacuum pressure increases; and altering the duration of the second portion as vacuum pressure increases. | 01-10-2013 |
20130289494 | Irrigation Source Identification System - An irrigation source identification system includes an irrigation source, an imaging device, and a processor. The irrigation source includes a container for holding a quantity of irrigation fluid and a port fluidly coupled to the container. The port has an outlet end and a neck. The neck has a plurality of protrusions selected from a grouping of protrusions. The plurality of protrusions provides a unique identifier for the container. An imaging device images the neck and the plurality of protrusions of the irrigation source, and the processor determines which identifier is associated with the image. | 10-31-2013 |
20140114236 | Pressure Control in Phacoemulsification System - A surgical system comprises a pressurized irrigation fluid source; an irrigation line fluidly coupled to the pressurized irrigation fluid source; a hand piece fluidly coupled to the irrigation line; an irrigation pressure sensor located at or along the pressurized irrigation fluid source or irrigation line; and a controller for controlling the pressurized irrigation fluid source. The controller controls the pressurized irrigation fluid source based on a reading from the irrigation pressure sensor and an estimated flow value modified by a compensation factor. | 04-24-2014 |
