Harmonic scaplel

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

6. What is the use of harmonic scalpel?

7. 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

8. What are the advantages of the Harmonic Scalpel?

9. 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

10. What Procedures Can the Harmonic Scalpel Accomplish?

11. 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 .

12. What are the Disadvantages of the Harmonic Scalpel?

13. 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.

15. 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.  

16. Conclusion 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 [ 2 ]. Ultrasicon is the name given to the dissection method by harmonic.

18. 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.
