20090048587 | System And Method For A User Interface - Embodiments of systems and methods for an interface for providing a user with feedback are presented. Specifically, embodiments of such an interface may include a head-up display unit which is mounted on a microscope utilized by a user when performing a surgical procedure. The heads-up display unit may include an eye-piece ring which is fitted onto or in one of the eye pieces of the microscope. The heads-up unit receives data regarding one or more parameters from a surgical console or other source and produces audio or visual feedback corresponding to a desired parameter. Any visual feedback produced may then be propagated to the eye piece ring allowing a user of the microscope to obtain the feedback when performing a surgical procedure utilizing the microscope and obviating the need to look at a screen of the surgical console to obtain such feedback. Thus, feedback is provided to a user in a non-intrusive manner such that the user can obtain this feedback without distracting from a surgical procedure. | 02-19-2009 |
20100004586 | Ultrasound Handpiece - A handpiece having at least one set of piezoelectric elements polarized to produce longitudinal motion when excited at the relevant resonant frequency. The piezoelectric crystals are connected to an ultrasonic horn to which a cutting tip is attached. The horn and/or the cutting tip contains a plurality of diagonal slits or grooves. The slits or grooves produce optimized torsional movement in the cutting tip when the piezoelectric crystals are excited at a second resonant frequency. | 01-07-2010 |
20100121364 | 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 to the tip to compensate for increased loads on the tip. | 05-13-2010 |
20100268388 | 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. | 10-21-2010 |
20110137232 | Thermal Management Algorithm For Phacoemulsification System - A control system for managing power supplied to a phacoemulsification hand piece includes a power source that provides power to the hand piece and a controller that controls the power source. The controller calculates a thermal value based on irrigation fluid flow and a power level and decreases the power level in proportion to the calculated thermal value when the calculated thermal value exceeds a threshold thermal value. Irrigation fluid flow can be calculated from irrigation fluid pressure. | 06-09-2011 |
20120302941 | PHACOEMULSIFICATION SYSTEMS AND ASSOCIATED USER-INTERFACES AND METHODS - Phacoemulsification systems and associated user interfaces and methods for use in ophthalmic surgery are disclosed. In some embodiments, a touch screen display of an ophthalmic surgical console provides a graphical user interface that allows a user to both visualize and control various operating parameters of the surgical console and associated subsystems. The controllable operating parameters include, without limitation, aspiration flow rates, IV pole height, vacuum limit pressures, minimum ultrasound power, maximum ultrasound power, on-time, off-time, and/or other values associated with the operating parameters of the ophthalmic surgical console. | 11-29-2012 |
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 |
20130211435 | 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 to the tip to compensate for increased loads on the tip. | 08-15-2013 |
