A Visionary Device Offering Better Results

 

• Selectively remove cement

• Preserving host bone​

​

Mechanism of Action

 The Axiom™ Ultrasonic Cement Removal System uses ultrasonic vibration to soften and remove polymethylmethacrylate (PMMA) bone cement during large joint revision surgeries. The system helps control bleeding and facilitates cement removal by transforming the rigid PMMA into a soft, malleable state through vibration-induced heat. This micro-movement makes extracting the cement easier and more efficient.

​

Principle of Operation

Ultrasonic surgery operates between 20-60 kHz, with the generator boosting frequency to 28 kHz. The hand-piece vibrates at 28,000 strokes per second, creating cavitation to soften and remove cement during revision arthroplasty.

Key features:

• Selective cement removal: Effectively extracts cement while protecting surrounding tissue, thanks to its high energy absorption and low thermal conductivity.

• Bone preservation: Ultrasound targets cancellous bone without affecting cortical bone, allowing precise removal and safe operation. Surgeons can detect probe position via audible and tactile feedback.
