Harmonic Scalpel Blades
A harmonic scalpel uses ultrasonic energy to dissect soft tissue and simultaneously coagulate blood at the incision. The hand piece (ultrasonic transducer) excites the resonant wave guide which transmits the ultrasonic energy to the scalpel blade. This method eliminates stray arcing and current effects that can occur with high frequency electric surgery methods.
Accellent manufactures harmonic scalpels in high speed machining centers using Titanium alloy bar, pre-qualified for acoustic resonant response and tuned using a proprietary technique.
