| titleOfInvention | Lens ultrasonic emulsification and suction device and method of operating the device |
| abstract | The present invention relates to a lens ultrasonic emulsification suction device, which is a handpiece having a cutting tip for emulsifying a lens, and a hand provided with a piezoelectric element for vibrating the cutting tip in a tool holder. A piece and an input terminal electrically connected to the tool holder for receiving an actual value proportional to a voltage induced in a piezoelectric element of the handpiece that constantly vibrates at a natural frequency; A regulator for determining a controlled variable compared to a prescribed target value; a power amplifier having an input terminal connected to the regulator and an output terminal connected to the tool holder for receiving the controlled variable; The power amplifier receives the actual value and simultaneously outputs power to the tool holder. It is possible to drive, directly fed back is achieved, so that the tool holder can always vibrate at an amplitude of the cutting tip in accordance with its natural frequency and the controlled variable. |
