Ultrasonic Unit SonicWeld Rx®
Instructions for Use
4 Operation
4.1
Function
The ultrasonic unit of the SonicWeld Rx® system converts electric energy into mechanical vibrations
(ultrasound). When using a standard sonotrode, the ultrasonic energy heats up the resorbable material at
the interfaces between the bone and the SonicPins, thus causing the SonicPins to glide into the predrilled
hole. When using a smoothing sonotrode, the ultrasonic energy heats up the Resorb x® or Resorb xG mesh,
plate, foil or membrane implants, thus allowing to smooth them out.
4.2
Safety Functions
Energy transmission is possible only if the resonance frequency of the sonotrode (11, front fold-out page) is
not altered by excessive mechanical load (e.g. when applying too much pressure to the SonicPin with the
handpiece). In such case of overload, the system is switched off automatically.
Built-in mains fuses protect the unit from overload.
The device automatically performs a self-test during start-up, see section 4.3.5, "Automatic Functional
Test", page 63.
During the self-test, the system checks that:
• all components required are connected
• the handpiece functions properly
• the basic insulation is intact
• the internal operating software has been loaded correctly
• the mains fuses are intact
Life hazard for the patient due to improper power connection!
• The device must not be combined with other devices.
• The device must not be connected to a mains that powers life-supporting systems.
