Ultrasonic Harmonic Shears

The Ultrasonic Harmonic Shear is a surgical instrument used to simultaneously cut and cauterise tissue. It is the latest device to have been introduced in the last decade or so.

Ultrasonic energy is famously used in Ultrasonic Shears where Ultrasonic energy is converted to mechanical energy at the active blade.

The main mechanism is the active blade which delivers high-grade frictional force while the inactive upper arm holds tissue in apposition. Its main advantages include precise dissection, reliable haemostasis, 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.

Ultrasicon is the name given to the dissection method by the Harmonic Scalpel.

The transducer in the handpiece consisted of piezoelectric crystal sandwiched under pressure among metal cylinders. The Ultrasonic generator converts Ultrasonic energy into mechanical energy. The sealing of the vessels is achieved due to denatured protein coagulum which occurs due to tamponade and coaptation.

It has three compatible probes that are the Shear, blade and a hook. The Shear can coagulate vessels up to 5 mm, whereas the hook and blade only 2 mm in diameter. It has the least thermal spread and smoke production of all the devices.

Our Ultrasonic Harmonic Shears are compatible with Covidien Machines and can function perfectly along with the Covidien foot switch.
