What is CUSA surgery?
The Columbus Neurosurgery Department now routinely uses a cavitron ultrasonic surgical aspirator ( CUSA ). The CUSA simultaneously fragments pathologic tissue while providing suction and irrigation. It distinguishes pathologic tissue from normal tissue, thus preventing damage to healthy parenchyma.
How does a CUSA work?
The vibration occurs with a frequency of 23 kHz and with an adjustable stroke of 0-300 microns. The tip of the device, placed in contact with the target tissues, destroys and emulsifies the cell membranes, which are irrigated and removed through a built-in suction tube.
What is a Cavitron ultrasonic surgical aspirator?
The Cavitron Ultrasonic Surgical Aspirator is a unique modality for precise tissue removal which results in increased visibility, reduced bleeding, and shorter operating time when dealing with vascular lesions or organs.
What does cavitron mean?
The Cavitron is a state-of-the-art ultrasonic cleaner that your hygienist uses every time you come see us for a dental wellness or gum care visit. During a dental wellness visit, the Cavitron uses a steady flow of water to wash away the debris that it has loosened from your teeth.
What is used for cavitation in ultrasound scan?
Ultrasonic cavitation device is a surgical device using low frequency ultrasound energy to dissect or fragment tissues with low fiber content. It is mainly used for tissues with high water content and low fiber content, like noncirrhotic liver and pancreas.
What is an ultrasonic aspirator?
Purpose: The Sonopet Ultrasonic Aspirator is a surgical tool that uses low-frequency ultrasonic vibrations to fragment tissue while simultaneously irrigating and aspirating the surgical field.
How does 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.
What does CUSA stand for?

Can ultrasonic scaler damage teeth?
One might expect ultrasonic scaling tools to be more hazardous for weak teeth , but the opposite is true. Manual scalers , which require a scraping force to be effective, have the potential to remove significant amounts of enamel , potentially exposing teeth to decay and causing tooth sensitivity in some patients.
Is ultrasonic scaling better than hand scaling?
While the ultrasonic does remove calculus (at a seemingly faster rate than hand scaling ), it doesn’t necessarily remove it all. It is best used to flush bacterial biofilm and plaque from under the gums. Localized or generalized hand scaling , with greater tactile sense for the hygienist, follows.
What is a piezo scaler?
Piezo Scaling Units Piezo electric ultrasonic scalers offer unique benefits over other kinds of scalers . They operate at a slightly higher frequency, require less water to control heat and vibrate less which achieves optimal patient comfort when removing plaque, calculus and more.
