The harmonic scalpel is a surgical instrument that utilizes ultrasonic vibrations to simultaneously cut and cauterize tissue, providing advantages such as reduced bleeding, quicker recovery time, and minimal thermal damage. It is versatile for various procedures, including endoscopic and open surgeries, but has disadvantages like reduced maneuverability and slower coagulation compared to traditional electrosurgical units. Overall, it represents a significant advancement in surgical technology offering precise dissection and reliable hemostasis.
![Conclusion
• The harmonic scalpel is a surgical instrument used to simultaneously
cut and cauterize tissue. It is the latest device to have been
introduced in last decade or so.
• Ultrasonic energy is famously used in Harmonic scalpel where
ultrasonic energy is converted to mechanical energy at the active
blade [1].
• The main mechanism is the active blade which delivers high-grade
frictional force while the inactive upper arm holds tissue in
apposition.](https://image.slidesharecdn.com/harmonicscaplel-180528075120/85/Harmonic-scaplel-18-320.jpg)

- 7. HARMONIC SYNERGY® Blades • HARMONIC SYNERGY® Blades use high-frequency mechanical vibration to simultaneously cut and coagulate at the same time, sealing vessels at lower temperatures than electrosurgery: • Precise: Minimal lateral thermal tissue damage for safer dissection near vital structures • Reliable: Seals and divides vessels <= 2mm, as well as lymphatics • Versatile: Cuts, coagulates and dissects, reducing instrument exchanges
- 8. What is the use of harmonic scalpel?
- 9. Uses • The Harmonic scalpel is a surgical instrument used to simultaneously cut and cauterize tissue. Unlike Electrosurgery, the harmonic uses ultrasonic vibrations instead of electric current to cut and cauterize tissue
- 11. What are the advantages of the Harmonic Scalpel?
- 12. Benefits of the Harmonic Scalpel • The Harmonic Scalpel's biggest advantage is the reduced bleeding and recovery time for the patient. Other advantages include the ability for a surgeon to make more precise cuts, and an overall reduction of lateral thermal tissue damage in comparison to other operating devices. • Operates as much lower temperature than other instruments – electrosurgical units(ESU).Produces very little if any smoke charring of tissue clearer surgical field
- 13. What Procedures Can the Harmonic Scalpel Accomplish?
- 14. What Procedures Can the Harmonic Scalpel Accomplish? • The Harmonic scalpel is used for endoscopic and open surgical procedures, and uses ultrasound. • The Harmonic Scalpel is used in dental and ophthalmic surgeries. Some specific procedures in which the device is used include: lung biopsies, gynecologic cancer, hemorrhoidectomy, thyroidectomy, and cholecystectomies.
- 15. What are the Disadvantages of the Harmonic Scalpel?
- 16. Disadvantages of the Harmonic Scalpel • The Harmonic Scalpel’s primary competitor is the Bovie. The Harmonic Scalpel is able to cut through thicker tissue. However, it is not as maneuverable and takes more time to coagulate and cut tissue. Additionally, the Harmonic Scalpel can only coagulate tissue when it cuts.

- 21. Research base • Burn accidents due to the use of electrosurgical instruments (electrotomy, electrocoagulation) are uncommon but generally serious: explosion of inflammable anaesthetics or antiseptics, local tissue necrosis by an uncontrollable current or coagulation necrosis by a high current. An appropriate use of electrosurgical instruments based on the correct range of indications is the basis for the prevention of accidents.
