  • Patent number: 11752035
    Abstract: A phacoemulsification transducer assembly includes a reflector and a driver connected to the reflector. The driver has a known driver vibration frequency range. A horn is connected to the driver opposite the reflector. A needle is connected to the horn opposite the driver. The needle has a known free shaft length. To maximize a desired stroke length of the needle for a minimal amount of power applied to the driver, a material forming the needle is chosen such that a speed of sound through the material results in a quarter-wavelength distance at the driver vibration frequency range substantially equal to the needle free shaft length.

  • Patent number: 11701222
    Abstract: An intraocular lens (IOL) injector is configured for single hand operation and employs a compressed gas to provide a motive force to present an IOL to a surgical site. The IOL injector includes a mechanical brake coupled to a plunger to preclude translation of an IOL absent operator input. The mechanical brake provides for selectively varying the speed and translation of the plunger, and hence IOL during presentation of the IOL to a patient. The IOL injector can also include at least a first stop, which halts movement of the plunger at a predetermined position. The at least first stop is then moved to a passing position, thereby allowing further operator controlled translation of the plunger to present the IOL to the surgical site.

  • Patent number: 11484441
    Abstract: A surgical needle assembly for attachment to an ultrasonic handpiece includes an elongated metal cannula having a distal end and a proximal end. A hub is insert molded onto the cannula generally towards the cannula proximal end and formed from a material having an ultimate strength at least twice a peak cyclical stress force at a joint between the elongated metal cannula and the hub when the surgical needle assembly is in use with the ultrasonic handpiece. The hub material has a stiffness sufficient to limit a motion of the elongated metal cannula to less than 1.5 times an expected peak to peak stroke length when the surgical needle assembly is in use with the ultrasonic handpiece. The hub includes structure for mating attachment to the ultrasonic handpiece.
