    摘要： A handpiece having a single 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. Preferably, the two drive frequencies are not coincident, but provided in non-overlapping pulses.

    摘要： A handpiece having a set of longitudinally vibrating piezoelectric elements and which may additionally have an electric motor to provide rotational or oscillatory movement to the ultrasound horn. The piezoelectric elements are surrounded by a high temperature plastic sleeve, and the sleeve is filled with high temperature potting material. The potting material seal the piezoelectric elements against moisture without affecting the performance of the piezoelectric elements.

    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： An intraocular lens (IOL) injection device is modularized to enable cleaning of internal components after surgery. The device includes first and second housing modules. These modules collectively define a passageway along which an injector rod moves between a retracted position and an extended position. The first module is further configured to accommodate a lens cartridge module. The cartridge module has disposed therein an IOL, in alignment with the passageway. Thus as the rod moves from the retracted position to the extended position, a front portion of the rod that is substantially surrounded by the first module in the retracted position moves into the cartridge module and displaces the IOL. This causes the front portion of the rod to accumulate on it viscoelastic substances. The first module, though, is configured to detach from the second module, to thereby expose the front portion of the rod in the retracted position for cleaning.

    摘要翻译： 模块化的眼内透镜（IOL）注射装置能够在手术后清洁内部部件。 该装置包括第一和第二壳体模块。 这些模块共同地限定了一个通道，喷射器杆沿着该通道在缩回位置和延伸位置之间移动。 第一模块还被配置为容纳透镜盒模块。 盒式模块在其中设置有与通道对准的IOL。 因此，当杆从缩回位置移动到延伸位置时，在缩回位置中基本上被第一模块包围的杆的前部移动到盒模块中并使IOL移位。 这导致杆的前部在其上积聚粘弹性物质。 然而，第一模块被配置为从第二模块分离，从而将杆的前部部分暴露在缩回位置以进行清洁。
