How to Use Harmonic Scalpel in Laparoscopic Surgery
This video demonstrates the functionality of Ultrasonic dissector called as Harmonic Scalpel. The harmonic scalpel is a surgical instrument used to simultaneously cut and cauterize tissue. It is the latest device to have been introduced in the last decade or so. Ultrasonic energy is famously used in the Harmonic scalpel where ultrasonic energy is converted to mechanical energy at the active blade.
The main mechanism is the active blade which delivers high-grade frictional force while the inactive upper arm holds the tissue in apposition. Its main advantages include precise dissection, reliable hemostasis, less lateral thermal spread and charring mainly works by applying pressure and then sealing with a denatured protein coagulum while applying ultrasonic vibration to denature hydrogen bonds perform vessel coagulation

In laparoscopic surgery, suturing skills are crucial in critical situations. The Extra Corporeal Dundee Jamming Knot, with its outside preparation and Aberdeen termination, proves highly valuable for maintaining tissue support and closure.

The harmonic shears I have used in Cholecystectomy and found effective and safe in as a sole instrument for sealing and division of the artery and cystic duct. The main advantages of using a Harmonic scalpel could be related to safety and decreased laparoscopic operative time.
