White Paper: Piezoelectric Transducers for Ultrasonic Surgery Tools
Materials and System Design Guidelines for Different Applications
Tools based on piezoelectric ultrasonic transducers are increasingly used in medical applications, including minimally invasive surgeries and dentistry. Common instruments used in advanced procedures are ultrasonic scalpels, phaco handpieces, and scalers. These devices leverage acoustic waves to efficiently process both hard and soft tissues. For instance, during oral surgery, ultrasound enhances mechanical actions like drilling, offering additional benefits such as shock or cavitation effects, leading to faster, more selective processing that safeguards surrounding areas, like blood vessels.
When addressing soft tissues like muscles, ultrasonic waves enable scalpel blades to oscillate at high frequencies, creating friction that allows for swift cutting and coagulation. This not only minimizes severe bleeding but also supports quicker hemostasis. The high energy density at the ultrasonic instruments’ contact point simplifies cutting, requiring less force and pressure, thereby making surgical incisions smaller and reducing trauma. Consequently, patients experience less postoperative pain, faster wound healing, and overall better recovery.
Moreover, ultrasonic medical tools can efficiently break down hard formations, such as tartar or kidney stones, through cavitation and acoustic forces, and liquefy soft tissues for minimally invasive removal, as seen in cataract surgeries (phacoemulsification) or wound debridement.
Ultrasonic devices, particularly scalers made from piezoelectric ceramics, are equipped with multi-functional features, including lighting, cooling water, gas, and suction options, enhancing their utility in procedures, such as tissue sealing and vascular surgery. These innovations highlight the significance of ultrasonic technology in advancing medical treatment and patient care.
Typical applications for piezoelectric ultrasonic scalers include:
- Tartar removal
- Intracorporeal stone disruption
- Ultrasonic scalpels and tissue sealing tools, e.g., in vascular surgery for coagulation
- Laparoscopic ultrasonic dissection
- Bone saws and drills, e.g., in orthopedics and maxillofacial surgery
- Ophthalmic phacoemulsification
- Ultrasound-assisted wound debridement
