Device for generating oscillations in a needle and process for operating a phacoemulsification probe

摘要

The invention relates to a device for generating oscillations in a needle, especially for a phacoemulsification probe, having an oscillator and a wave guide which physically couples together the needle 94 and the oscillator. A reflector 43 compresses the oscillator 3 against the wave guide by means of a spring member in the form of a tube 66 connecting the reflector 43 and the wave guide. The invention further relates to a process for operating a phacoemulsification probe having a mechanical oscillator 3 coupled to a needle 96. The energy generated by the oscillator and directed away from the needle is reflected towards the needle by a reflector 43 and the oscillator is compressed between the reflector 43 and a wave guide by a spring member in the form of a tube 66.
