Harmonic Scalpel Devices MCQS QUIZ TEST
Harmonic Scalpel Devices MCQS QUIZ TEST
The harmonic scalpel is like a high-tech cutter used by surgeons during operations. Instead of using heat, it works with special sound waves to carefully cut and seal tissues. Imagine a small device that vibrates very fast, between 20,000 and 50,000 times per second. The surgeon holds this device, which has a part that sends out ultrasound and a tiny scalpel, and they control it using a switch in their hand or a pedal with their foot. Even though it takes a bit longer to use compared to another method called diathermy, the harmonic scalpel claims to make things better after surgery. It says it can reduce problems like swelling, bleeding, and bruising.
