When would you use a harmonic scalpel?
Medical procedures that can be performed using the harmonic scalpel include thyroidectomy, lung biopsy, laparoscopic cyst decortication, tonsillectomy, and gynaecologic cancer.
What are the advantages of the harmonic scalpel?
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].
What is the difference between LigaSure and harmonic scalpel?
Unlike the LigaSure, the Harmonic scalpel is also able to cut through tissue as it coagulates. Both the LigaSure device and Harmonic scalpel have been demonstrated to be safe in numerous papers [17-20].
What are harmonic shears?
HARMONIC ACE+ Shears can be used for coagulation and transection of vessels up to 5 mm and handle multiple surgical jobs with precision including dissection, sealing, transection, and otomy creation. The refined blade design includes a tapered tip with a proprietary, nonstick coating.
How much does a harmonic scalpel cost?

How does a surgical harmonic work?
A harmonic scalpel cuts via vibration. The scalpel surface itself cuts through tissue by vibrating in the range of 55,500 Hz. The high frequency vibration of tissue molecules generates stress and friction in tissue, which generates heat and causes protein denaturation.
Is LigaSure monopolar or bipolar?
LigaSure (bipolar vessel sealing) technology is a radiofrequency-driven bipolar electrosurgical device. A tissue-based feedback program is used to regulate the dose of energy administered, which is appropriate for bulk tissue or vessel density, and the aim is to limit the heat generated in the target tissue.
What is the difference between electrocautery and electrosurgery?
Often, the term ‘electrocautery’ is incorrectly used to describe electrosurgery. Electrocautery refers to direct current (electrons flowing in one direction) whereas electrosurgery uses alternating current. In electrosurgery, the patient is included in the circuit and current enters the patient’s body.
What is a Thunderbeat device?
THUNDERBEAT is the world’s first and only advanced energy system that delivers two well-established forms of energy to a tissue simultaneously: Ultrasonic energy for precise and efficient dissection. Advanced bipolar energy for secure haemostasis and sealing of vessels up to 7mm in diameter.
How do you use a microdebrider?
The microdebrider works by employing suction to pull tissue into the aperture of the blade, which cuts the tissue. Suction is used to simultaneously remove tissue-and blood-from the site, allowing much better visibility for the surgeon.
