Langevin Piezoelectric Transducers for Advanced Surgical Tools

Langevin transducers convert electrical energy into precise ultrasonic vibration, delivering stable, high-power output for medical procedures such as tissue cutting, emulsification, and other therapies requiring consistent and controlled ultrasonic energy.

Medical Application Examples

• Ultrasonic scalpels – precision cutting with simultaneous coagulation for soft tissue procedures
• Surgical devices – minimally invasive soft tissue dissection and vessel sealing
• Dental scaling – ultrasonic removal of plaque and calculus
• ENT and neurosurgical aspirators – ultrasonic fragmentation and aspiration of soft tissue
• Ultrasonic-assisted liposuction – emulsification of adipose tissue
• Ultrasonic wound debridement – removal of necrotic tissue and biofilm
• Orthopedic ultrasonic tools – bone cutting and cement removal

Leading Langevin Transducer Manufacturer

Piezo Technologies’ long history as an ultrasonic transducer supplier to healthcare OEMs makes us an ideal partner to engineer the entire acoustic stack to the highest standards and deliver acoustic engineering horsepower.

• Stable resonance frequency
• High power handling without thermal runaway
• Material consistency (piezoceramic properties must be identical lot to lot)
• Amplitude and displacement control for predictable cutting/emulsification
• Low mechanical losses and high electro-mechanical coupling
• Ability to model, tune, and optimize the full transducer to meet customer requirements (ceramic stack, bolt, mass, horn, booster, etc.)

Our vertically integrated in-house piezoceramic manufacturing reduces the risk of sourcing critical components from a third party.

• Stable chemical consistency
• Predictable lot-to-lot performance
• Controllable frequency, impedance, and coupling
