Dynamic ultrasonic fatigue stress measurement

• Ultrasonic aspirating surgical and industrial handpieces and tips, piezo-electric and magnetostrictive transducers, horn and generator design. 10 to 2,000 Watts, 15 to 100 kHz, self tuning, pulse width modulated and sinusoidal amplitude controlled regenerative power limited generators.

• Integral endoscopic ultrasonic aspirators for urologic, gynecologic, orthopedic and minimally invasive surgery having irrigation, aspiration, illuminated glass relay lens or fiberoptic telescope and isolated electro-cautery capable ultrasonic tip connection.

• Autoclavable, hermetic transducers and seamless, cavity free aspiration channels with true motionless acoustic terminations for tubing connections.

• Temperature sensitive tips and temperature control.

• Existing system compatible components or complete system designs, including rotary, mixed mode and high amplitude titanium and stainless steel Gaussian horns. Prototype fabication, manufacturable designs and documentation.

• Analysis of existing systems and material analysis for correction of operational or production problems.
