Which surgical device uses vibrations to cut and coagulate tissue?

• A. Fulguration
• B. Electrosurgical unit
• C. Ultrasonic scalpel
• D. Plasma

Answer: (C)

The ultrasonic scalpel is a surgical device that utilizes high-frequency ultrasonic vibrations to cut and coagulate tissue simultaneously. This technology allows for precise incisions while minimizing tissue damage and reducing blood loss, as the ultrasonic vibrations create heat that seals the tissue as it cuts. The unique capability of the ultrasonic scalpel to emulsify tissue while maintaining hemostasis makes it particularly valuable in delicate or intricate surgical procedures. In comparison, fulguration refers to a technique using electrical current to destroy tissue, but it does not rely on vibrations for cutting. The electrosurgical unit, while also employing electrical current, primarily operates through thermal effects rather than vibrations. Plasma technologies, often used in various advanced applications, do not specifically utilize vibrations for tissue manipulation in the same way as the ultrasonic scalpel. Thus, the ultrasonic scalpel stands out for its specific use of vibrations in surgical procedures.
