  • Ultrasonic shaping instrument
    Patent number: 7172420
    Abstract: The invention concerns an ultrasonic shaping instrument comprising: a mount structure (10), a sonotrode (14) elastically mounted on the mount structure (10), a tool (16) fixed to the sonotrode (14) for carrying out shaping operations, and a control member (12) for controlling and powering the sonotrode (14). The instrument is dimensioned so that the assembly consisting of the sonotrode (14) and the tool (16) has a resonance ultrasonic frequency fo, in a mode selected among traction-compression and torsion, variable between a lower limit fomin and an upper limit fomax, and it does not have itself any other resonance frequency in a range between a frequency fpmin<fomin and a frequency fpmax>fomax.
