Ultrasonic bone knife tooth extraction features

Ultrasonic bone scalpel tooth extraction is an innovative bone surgery method that utilizes piezoelectric ultrasound. It can identify soft and hard tissues and use cold cutting methods, which will greatly improve the accuracy of the operation and greatly improve safety. It mainly uses high-intensity focused ultrasound technology to convert electrical energy into mechanical energy, which can form high-frequency ultrasonic oscillations, so that it can cut the required bone tissue, which will greatly improve safety when extracting teeth.

The principle of ultrasonic osteotome

As a new type of orthopedic surgical equipment, it uses high-intensity focused ultrasound technology to convert electrical energy into mechanical energy through a special conversion device, and cuts the required bone tissue through high-frequency ultrasonic oscillation.

1. It can selectively cut tissues: It takes advantage of the high acoustic impedance of bone tissue and the low acoustic impedance of soft tissue. When the operating frequency of the ultrasonic bone knife is lower than a certain critical value, it can directly produce mechanical destructive effects on bones with high acoustic impedance and calcified and mineralized hard tissues. However, it is not suitable for cutting soft tissues with low acoustic impedance. Due to this function, it can avoid damage to soft tissues such as mucosa, blood vessels and nerves to the greatest extent. Even if the blade touches the soft tissue, it will not cause damage to it, thereby reducing the risk and difficulty of operation. Especially for patients whose tooth roots are closely related to nerves, ultrasonic osteotome can greatly reduce the chance of nerve damage. 2. Cold cutting mode: The ultrasonic bone knife generates very little heat when cutting. In addition, an appropriate amount of cooling forms water mist that is sprayed on the surgical area to ensure that the wound temperature is below 38°C. The water mist flushes the wound to make it clear and bleeding-free during the operation, and the surgical field is well visible, making the operation easier. The wound surface and incision do not heat up, which ensures the survival of cells in the surgical area, reduces damage, and accelerates postoperative wound healing.
