collapse of vapor pockets around cells in tissues having high water content. The collapse of the vapor
pockets formed in such tissues results in tissue rupture.
3.4 System Overview
The SonaStar Ultrasonic Aspirator consists of a microprocessor-based control system and a handpiece,
providing precise surgical tissue removal. The SonaStar is a fully self-contained console with built-in
irrigation, aspiration and vibration systems. When combined with an approved electrosurgical unit, the
system is able to perform electrosurgery functions, as well. This is discussed in further detail in Chapter
7.
The vibration system fragments tissue in contact with the distal end of the titanium tip of the
handpiece. Irrigating solution is provided coaxially around the tip within a protective sleeve to emulsify
the fragmented tissue, to cool the tip, the excision site and the handpiece transducer. A vacuum pump
in the console provides simultaneous aspiration in order to remove fragmented tissue and irrigating
solution from the operative site, through the aspiration channel of the handpiece and disposable
tubing, and into a collection canister.
The irrigation, aspiration and vibration systems are described in greater detail in the next sections of
this chapter. Flow diagrams for each system show how they function. The controls are described in
Chapter 4.
