55khz ultrasonic transducer for bone cutting knife for medical

 


Ultrasonic bone cutting knife makes it the preferred tool for leading surgeons who want high performance every time. Ultrasonic bone cutting knife leaves elastic soft tissues largely unaffected while efficiently slicing through crystalline bone. The revolutionary ultrasonic technology amplifies electrical signals that are then converted into a high-speed back-and-forth motion of the blunt blade.
The ultrasonic tool provides the ability to make large challenging osteotomies with ease without compromising safety. The speed to which the device cuts through bone allow users to maintain short operative times while improving the overall efficiency of the procedure.
Ultrasonic bone cutters have much higher requirements for ultrasonic transducers than ordinary transducers. Ultrasonic transducers must meet the requirements of: light weight, high amplitude, and small volume. This 55K piezoelectric ceramic transducer is specially designed for ultrasonic osteotomy blades for medical applications. It can reach an amplitude of 30um. After the output of the horn is amplified, it can reach an amplitude of 60um. However, for high-amplitude vibration, ultrasonic tools The material requirements of the head are relatively higher.
Ultrasonic bone-cutting devices are new cutting tools and have low frequency ultrasonic blade. There is limited data on the safety and effectiveness of using ultrasonic bone-cutting devices in the treatment of adult spinal deformities.
An ultrasonic bonecutting device is safe in the adult spinal deformity population and to compare its effectiveness in blood loss reduction by using a comparison group from a prospective multicenter database of adult spinal deformity patients.

Piezosurgery is an innovative osteotomy technique using piezoelectric ultrasonic vibrations. Ultrasonic vibrating instruments for cutting mineralized tissue have been reported since the 1950s In 1988, Italian oral sugeon, Tomaso Vercellotti, developed a piezoelectric osteotomy device, which provided the opportunity for the widespread clinical use of piezosurgery Currently, piezoelectric devices are used widely for osteotomies, such as maxillary sinus lift, impacted mandibular third molar extraction, and bone grafting, in the field of oral and maxillofacial surgery.
The major advantage of piezosurgery is its selective cutting of mineralized bone. Frequencies higher than 50 kHz are needed to cut soft tissues. The piezoelectric device is designed to produce ultrasonic microvibrations of 60-210 μm at a frequency of 25-30 kHz. Thus, piezoelectric devices, different from conventional rotary instruments and microsaws, are able to cut only mineralized tissues. Therefore, piezosurgery can reduce considerably the risk of damage to adjacent soft tissues, such as blood vessels, nerves, and mucous membranes, in cases of osteotomy. Other advantages of piezosurgery include reduction of overheating resulting from the generation of a cavitation effect and better visibility of the surgical area due to less bleeding. Moreover, use of piezosurgery for extraction of the impacted mandibular third molar was reported to produce less facial swelling and trismus postoperativily compared to that of rotary osteotomy. Recent studies on the healing of bone defects experimentally created by piezosurgery demonstrated no difference in the newly formed bone volume and the healing process between piezosurgery and conventional osteotomy techniques. Meanwhile, piezosurgery was shown to have a longer surgical time than conventional osteotomie.
