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 is the ideal temperature for vessel sealing?

Tissue sealing is achieved at temperatures of around 100 °C, whereas (nonmechanical) cutting requires temperatures of around 150–200 °C [17, 18].

What type of energy is LigaSure?

LigaSure™ uses a combination of pressure and continuous bipolar energy to create vessel fusion. LigaSure™ seals vessels by applying high, uniform mechanical compression while monitoring and adjusting energy delivery to the tissue.

What is LigaSure in surgery?

LigaSure is a bipolar clamping device used in open and laparoscopic surgeries for producing haemostasis in vascular pedicles up to 7 mm in diameter (“Covidien LigaSure technology: consistent, reliable, trusted vessel sealing,” 2012).

How does a 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.

How hot does a harmonic scalpel get?

1 The Harmonic ® scalpel may reach temperatures in excess of 200°C, produces peak temperatures after deactivation (when adjacent tissues are prone to injury if the instrument is not handled carefully) and takes longer to cool than some other thermal devices.

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].

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.

Is LigaSure an electrosurgery?

The complete “LigaSure Vessel Sealing System”, including an electrosurgical generator and several types of forceps. The LigaSure Vessel Sealing System allows hemostasis by vessel compression and obliteration through the emission of bipolar energy. It includes (Figure 1):

Does LigaSure cut tissue?

The LigaSure Impact™ sealer/divider can grasp, seal, and cut tissue independently — or you can perform all three in one step. The device’s large jaws also: Enable fast transection.

Is a LigaSure bipolar?

What are the advantages of the Harmonic Scalpel?

How much does a Harmonic scalpel cost?

Is Harmonic scalpel bipolar or monopolar?

Monopolar diathermy, Harmonic scalpel and LigaSure are routinely used in open and laparoscopic surgery for tissue cutting and hemostasis.

What is the difference between cut and COAG?

Cut/Coag Most wet field electrosurgical systems operate in two modes: “Cut” causes a small area of tissue to be vaporized, and “Coag” causes the tissue to “dry” (in the sense of bleeding being stopped).

What are the two types of electrosurgery?

Electrosurgery is a term used to describe multiple modalities that use electricity to cause thermal destruction of tissue through dehydration, coagulation, or vaporization. The two types of electrosurgery most commonly used are high-frequency electrosurgery and electrocautery.

What is a Maryland jaw?

Designed for Thoracic Surgery1,2,3,4,5. A multifunctional nano-coated instrument designed for sealing pulmonary veins and arteries up to — and including — 7 mm1–5.

What does a harmonic scalpel do?

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.

How does harmonic scalpel work?

What is soft COAG?

SOFT COAG is a coagulation mode unique to VIO electrosurgical units (ERBE Elektromedizin GmbH, Germany). This system regulates the temperature rise below boiling point without generating sparks, which is high enough to denature protein.

What are the 2 types of electrosurgery?

What is the most common adverse event associated with the electrosurgical unit?

Device failure was the most common adverse event (202 events, 31%), followed by burns in 187 patient (98% of burns) and three provider events (2%).

What is Thunderbeat haemostasis and how does it work?

For the exact exposition and transection of the correct multiple vessel structures in vulnerable liver tissue, superior THUNDERBEAT haemostasis enables unbeatable, fast, effective transection of the parenchymal tissue. Small and medium size vessels are sealed efficiently to avoid bile leakage or major bleeding, and maintain necessary visualisation.

How is Thunderbeat used to reduce blood loss?

Small and medium size vessels are sealed efficiently to avoid bile leakage or major bleeding, and maintain necessary visualisation. With the additional facility to pre-seal and apply secondary haemostasis, both the potential for and reduction of blood loss can be achieved using THUNDERBEAT.

What is Thunderbeat bipolar energy?

THUNDERBEAT bipolar energy provides secure vessel sealing for short gastric vessels up to 7mm and reliable haemostasis when chasing bleeders. Rapid dissection is achieved in gastric sleeve and bypass procedures with the combination of ultrasonic and bipolar energy.
