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].
How does the harmonic scalpel 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.
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.
Is harmonic scalpel bipolar?
Harmonic scalpel uses ultrasound technology to coagulate and to cut tissues. Small Jaw device uses bipolar electrical energy and pressure to form a seal and a micro blade to divide the sealed tissues….Information from the National Library of Medicine.

What type of energy does a harmonic scalpel use?
THE HARMONIC scalpel is a new device that has been introduced to surgery during the last decade. It is a device that uses high-frequency mechanical energy to cut and coagulate tissues at the same time.
Is harmonic scalpel reusable?
According to the findings of this study, the two harmonic scalpels tested cannot be reused, because they cannot be easily disassembled and thus, the cleaning process is compromised.
What is a Cavitron ultrasonic surgical aspirator?
The Cavitron ultrasonic surgical aspirator (CUSA: Integra lifesciences Corporation, NJ, USA) is a device originally used mainly for hepatic parenchyma resection in the gastrointestinal surgical field. Tissue is selectively fragmented by an ultrasonically vibrating chip at the tip of the device.
Is Harmonic Scalpel reusable?
What is an Enseal device?
Enseal® X1. ENSEAL® X1 Large Jaw Tissue Sealer instrument is a dedicated bipolar electrosurgical instrument intended for use in open surgical procedures where ligation and division of vessels is desired. It is a bipolar instrument for use with the Ethicon Generator G11 (GEN 11).
What is Thunderbeat?
Background: The THUNDERBEAT (TB) is a relatively novel energy device that is used in laparoscopic colorectal resection (LCR), which integrates both ultrasonic and bipolar energy.
What does cavitron mean?
A Cavitron is a high frequency sound wave tooth used by our hygienists to clean teeth. The ultrasonic sound waves vibrate the dirt, tarter, and plaque off teeth.
