Ultrasonic dissection products are advanced surgical instruments that use high-frequency ultrasonic vibrations to cut tissue and simultaneously coagulate blood vessels. They are widely used in minimally invasive and open surgeries to improve precision and reduce bleeding.

These systems are commonly referred to as harmonic scalpels or ultrasonic shears.

Principle of Operation

Ultrasonic dissection devices work by converting electrical energy into mechanical vibrations (typically around 55,000 Hz).

These vibrations:

• Break hydrogen bonds in tissue proteins

• Produce cutting (coagulation + dissection)
