    摘要: 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.

    摘要: A capsulorhexis apparatus includes a capsulorhexis probe configured for insertion into an eye through an incision and a pulse generator configured to deliver at least one radio-frequency (RF) pulse to the capsulorhexis probe. The delivered RF pulse has a pre-determined attenuation profile such that the power level of the delivered RF pulse is substantially attenuated over the RF pulse's duration. In some embodiments, the pulse generator is configured to deliver a series of two or more RF pulses to the eye, such that the energy of each of the second and subsequent pulses of the series is substantially attenuated relative to the energy of the immediately preceding pulse.

    摘要: 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.

    摘要: Method for controlling an ultrasonic handpiece of an ocular surgical system, such as a phacoemulsification system. First and second signal sources generate first and second drive signals. The first signal is at a first frequency and is used to drive a cutting tip of the handpiece with a first type of motion. The second signal is at a second frequency and is used to drive the cutting tip with a second type of motion. The different motions can be generated with different first and second frequencies. The first and second signals can be summed or combined and provided to a class D amplifier, the output of which includes multiple frequency components or multiple signals of different frequencies to drive the cutting tip in different directions at the same time, for example, with simultaneous longitudinal and torsional motions.

    摘要: A system and method for tuning and controlling ultrasonic handpieces by varying the frequency of the drive signal that is fed to the handpiece by a discrete dither increment. A digital signal processor may be used to measure the response of the handpiece to the varying drive signal and compare these responses to determine the probable value of the actual series resonance. The output of the digital signal processor is used to generate control parameters embodied within an appropriate control signal, which is fed to the source of the drive signal in order to alter aspects of the drive signal.

    摘要: 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.
