System Overview
5.1.
Principle of Operation
The neXus Ultrasonic Surgical Aspirator System is comprised of a generator which converts mains voltage and frequency to a
22.5 kHz (Standard Handpiece) or 23.0 kHz (SonaStar Short & Long Handpiece) electrical signal depending upon the handpiece
and accessories that are connected to the console. The generator feeds the electric signal to a piezoelectric transducer
comprised of a ceramic crystal stack in the handpiece. The crystals vibrate at the output frequency translating the electrical
energy into mechanical vibration. A titanium horn amplifies the vibration and transmits the amplified vibration to a titanium
probe tip. The titanium probe tip is the applied part that comes into contact with patient tissue. An integrated irrigation pump
delivers an irrigation solution to the surgical site. An integrated aspiration system removes the fragmented, emulsified
material and waste liquids from the area. Accessories include various horn/probe tips, irrigation & aspiration tubing sets,
wrenches, and cleaning brushes.

Refer to the handpiece IFU’s for cleaning and sterilization procedures for the reusable handpiece parts and
accessories.
CAUTION Only external surfaces of the console should be cleaned. Do not attempt to remove any panels in
order to clean or disinfect internal surfaces.
