Application of Piezoelectric Ceramics in Ultrasonic Surgery
What is Ultrasonic surgery?
Ultrasonic surgery is a minimally invasive surgical technique that uses high-frequency sound waves to perform various surgical procedures. The sound waves are generated by a specialized instrument called an ultrasonic scalpel or surgical aspirator, which converts electrical energy into mechanical energy.
The mechanical energy produced by the ultrasonic scalpel is used to precisely cut, dissect, and remove tissues, making it an ideal tool for a wide range of surgical procedures, including but not limited to:
Soft tissue surgery: Ultrasonic surgery is often used to remove soft tissues such as tumors, cysts, and fibroids.
Eye surgery: Ultrasonic surgery is sometimes used to remove cataracts, to treat retinal detachment, and to perform other ophthalmic procedures.
Orthopedic surgery: Ultrasonic surgery can be used to remove bones, cartilage, and other tissues during orthopedic procedures.
Neurosurgery: Ultrasonic surgery is used to remove brain tumors and other neurological conditions.
Gynecologic surgery: Ultrasonic surgery is sometimes used to remove uterine fibroids, cysts, and other reproductive conditions.
Ultrasonic surgery offers several benefits over traditional surgical techniques, including less blood loss, reduced scarring, and faster recovery times. It is also less invasive, which can result in less pain and fewer complications.
In addition, the high-frequency sound waves generated by the ultrasonic scalpel are able to precisely cut and remove tissues while minimizing damage to surrounding structures, making it an ideal tool for minimally invasive surgical procedures.
How Ultrasonic surgery works?
Ultrasonic surgery works by using high-frequency sound waves to precisely cut, dissect, and remove tissues. The sound waves are generated by an instrument called an ultrasonic scalpel or surgical aspirator, which converts electrical energy into mechanical energy.
Here’s how the process works:
Generation of sound waves: The ultrasonic scalpel consists of a piezoelectric transducer that converts electrical energy into high-frequency mechanical vibrations. These vibrations are transmitted to the tip of the scalpel, where they are used to generate the sound waves.
Cutting and removing tissue: The high-frequency sound waves generated by the scalpel create microscopic bubbles in the tissue, which rapidly expand and collapse. This process, known as cavitation, generates high mechanical forces that can precisely cut, dissect, and remove the tissue.
Aspiration: In some cases, the ultrasonic scalpel may also be used to aspirate or remove tissues. This is achieved by attaching a suction device to the scalpel, which allows the surgeon to gently remove tissues as they are being cut.
Visualization: Ultrasonic surgery is often performed using a magnified visual system, such as an operating microscope or endoscope, to provide the surgeon with a clear view of the surgical site. This allows the surgeon to precisely target the tissues they wish to remove while minimizing damage to surrounding structures.
The high-precision and minimally invasive nature of ultrasonic surgery make it an ideal tool for a wide range of surgical procedures, including soft tissue surgery, eye surgery, orthopedic surgery, neurosurgery, and gynecologic surgery. The precise cutting and removal of tissues also result in reduced blood loss, reduced scarring, and faster recovery times, making ultrasonic surgery a highly sought-after surgical technique.
Which piezo elements can be used for Ultrasonic surgery?
Usually, monolayer piezo components are used in ultrasonic surgery tools. Transducers require medium power elements, for example, small rings made of our hard doped material PZT-41, which is designed for medium to high power devices. he-shuai can provide piezoelectric components according to your specifications.
The choice of piezoelectric material will depend on several factors, including the desired frequency of the sound waves, the size and shape of the transducer, and the specific surgical application.
In general, piezoelectric transducers are designed to have a specific resonant frequency, which is the frequency at which they will generate the most mechanical energy. The resonant frequency is determined by the size, shape, and material properties of the transducer, and is carefully controlled during the manufacturing process to ensure that the transducer operates at the desired frequency.
Overall, the use of piezoelectric transducers in ultrasonic surgery provides a highly precise and minimally invasive means of performing surgical procedures and is a crucial component of this cutting-edge surgical technique.
