Ophthalmosurgical control device for use in ophthalmosurgical system, comprises frequency generator, where frequency generator includes frequency module arranged to generate oscillation signal with frequency

摘要

The ophthalmosurgical control device (1) comprises a frequency generator (2), where the frequency generator includes a frequency module (3) arranged to generate an oscillation signal with a frequency (f1). The generated frequency is lower than an ultrasonic resonance frequency of an ophthalmosurgical piezoelectric device. Another frequency module (4) is arranged to generate another oscillation signal with another frequency (f2). A frequency generator control module (5) is provided for driving the former frequency module and latter frequency module.
