ultraäänileikkauksessa

Ultraäänileikkauksessa, often translated as ultrasonic surgery or high-frequency ultrasound surgery, refers to a surgical technique that utilizes high-frequency ultrasonic vibrations to cut and coagulate tissue. This method is a type of minimally invasive surgery, aiming to reduce trauma and improve recovery times compared to traditional scalpel-based procedures.

The principle behind ultrasonic surgery involves a specialized instrument that converts electrical energy into mechanical energy, creating vibrations at a frequency of around 55,000 Hz. These high-speed vibrations are transmitted through a tip, which can then precisely cut through tissue by breaking molecular bonds. Simultaneously, the heat generated by the friction of these vibrations causes protein denaturation, leading to coagulation and sealing of blood vessels. This hemostasis, or stopping of bleeding, is a key advantage of the technique, as it minimizes blood loss during the procedure.

Ultrasonic surgery instruments are typically used for dissection, tumor removal, and tissue ablation in various surgical specialties, including gynecology, general surgery, and neurosurgery. The precision offered by the ultrasonic tip allows surgeons to work around delicate structures, reducing the risk of damage to adjacent tissues. Compared to electrocautery, ultrasonic surgery generally produces less thermal spread, which can be beneficial in preventing collateral damage. The technology is continuously evolving, with advancements focusing on improving instrument design, energy delivery, and integration with imaging technologies for enhanced surgical accuracy.
