CUSA is the acronym for cavitronic ultrasonic surgical aspirator. This device is used in tumor surgery in a select number of hospitals around the world, and even fewer veterinary hospitals.
The CUSA uses ultrasonic frequencies to emulsify the target tissues. The ultrasound waves cause the cells to dissociate from one another while the device irrigates the area with sterile saline. The same handpiece then aspirates the fluid back out of the surgical site. Since this device can be fine-tuned, it allows the surgeon to remove tumors with minimal effect on the adjacent tissues. It can even ‘skeletonize’ the blood vessels which significantly decreases intraoperative bleeding.
The CUSA may be used for removal of brain tumors, spinal cord tumors, and other delicate procedures involving the central nervous system. Another integral part of this device is the bone tip. By delivering longitudinal-torsional movement, the bone handle can emulsify (or liquify) bone in very delicate areas while protecting adjacent vital tissues.
