IVT
ultrasonic energy device
A surgical instrument that uses high-frequency sound waves to cut tissue and achieve hemostasis simultaneously.
Full Definition
Ultrasonic energy devices utilize ultrasonic frequencies (typically 55,500 Hz) to vibrate a titanium blade, creating simultaneous cutting and coagulation effects through protein denaturation and vessel sealing. These devices generate minimal thermal spread compared to electrocautery, making them ideal for delicate tissue dissection near critical structures. The technology offers precise tissue effect control and produces minimal smoke, enhancing visualization during laparoscopic procedures.
Usage
Usage note: Preferred over brand names in formal medical documentation.
