Chapter 2 - Introduction to the CUSA® Clarity System
2.1 Overview
This section provides general information about the CUSA® Clarity Ultrasonic Surgical Aspirator System: what it is, what it does, and how it works.
The system is an ultrasonic surgical aspirator system that allows a surgeon to remove tissue efficiently and selectively. It performs three functions:
fragmentation, irrigation, and aspiration.
2.1.1 Fragmentation
The console supplies the high-frequency handpiece with an alternating voltage signal at 36,000 cycles per second (36 kHz). This voltage moves to
opposite poles of a stack of piezoelectric ceramic discs fastened to the metallic body inside the handpiece. The resulting oscillating electric field causes
the discs to vibrate. This vibration transitions down the length of the metallic body and into the surgical tip. The slender, tapered shape of the surgical
tip focuses the vibrational energy at the tip of the handpiece. Fragmentation occurs when the vibrating tip meets the tissue, causing the tissue to break
apart.
CAUTION
High frequency surgical equipment can affect the function of medical electrical devices such as ultrasonic aspirators. When using monopolar high
frequency surgical equipment simultaneously with the CUSA Clarity system, contact between the activated monopolar electrosurgery instrument
and the CUSA Clarity surgical tip could affect system functionality. Avoid contact between the CUSA Clarity surgical tip and an activated monopolar
surgical instrument.
2.1.2 Irrigation
The system transfers irrigation fluid from a user-supplied IV saline or Lactated Ringer’s solution to the distal tip of the handpiece. Sterile irrigation fluid flows
from an IV set (bole or bag and IV administration tubing) to a variable speed peristaltic pump.
The pump:
• Moves fluid at 2 to 20 mL/min; default flow is 3 mL/min. Use the adjustment slider (move the slider up/down on the Irrigation column on the touch
screen) to increase or decrease the irrigation flow in 1 mL/min increments.
• Accelerates to a Fast Flush speed, pumping at 25 mL/min ± 0.5 mL/min. The Fast Flush pedal on the system footswitch activates the Fast Flush feature.
The pump pushes the fluid through the manifold irrigation tubing to a flue, a sleeve surrounding the vibrating tip. As the irrigation fluid passes through the flue,
it cools the tip.
When the fluid reaches the distal end of the tip, as much as 99% of it passes through two pre-aspiration holes in the tip, preventing fluid pooling in the sterile
field and continually clearing the suction system. Fluid that does not pass through the pre-aspiration holes irrigates the surgical site and suspends fragmented
tissue.
2.1.3 Aspiration (Suction)
Aspiration enables Constant Tissue Contact, the consistent, tangible contact between tip and tissue, which is essential in efficient tissue resection. A
vacuum pump in the console provides nominally 640mmHg maximum dead head vacuum at sea level. Use the adjustment buons (move the slider up/
down on the Aspiration column on the touchscreen display) to increase or decrease the suction from 10 to 100% in 5% increments; default is 60%.
The suction, which produces an air stream moving toward the vacuum pump, pulls irrigation fluid, fragmented tissue, and other materials through the
distal end of the surgical tip. From the tip, the aspirated materials pass through the handpiece and manifold suction tubing into the suction canister. From
the suction canister, the air stream continues to flow through a contamination guard that filters any remaining particulate maer or moisture, preventing
them from entering the vacuum pump.
The accuracy of the vacuum level in the aspiration tubing at the port of the handpiece is ± 66 mmHg and never less than 30 mmHg.
A suction pinch valve on the front of the console opens when the system is on, and closes to stop suction when:
• Priming the irrigation system
• Pressing the Fast Flush pedal
• Releasing the amplitude pedal in Run Status (in this case, the pinch valve closes for approximately one second, then re-opens).
• Releasing the amplitude pedal in the on demand aspiration mode, this suction stoppage prevents depletion of the pneumoperitoneum.
When powered off, the system’s suction pump remains off and the suction pinch valve remains closed. Use the pinch value buon on the front of the
suction pinch valve to open the valve manually

2.2.2 Handpiece Components
The CUSA® Clarity handpiece is a hand-held surgical device. It houses a transducer that vibrates at an ultrasonic frequency, transferring the vibrations to
a hollow titanium tip. When applied to patient tissue, the vibrating tip provides the desired surgical effect – the fragmentation and removal of specific
tissue. The handpiece connects to the console by a handpiece cable and by the CUSA Quick Connect™Cartridge and Tubing Set.
Components of Assembled Handpieces
Handpiece
The handpiece body contains:
• Transducer to convert electric energy into mechanical motion
• Aspiration port to connect the aspiration tubing to the handpiece
The handpiece cable contains:
• Electric wires (deliver electric power from console to drive the handpiece)
• Connector that aaches the handpiece cable to the console
The connecting body serves as the connecting point for the tip and transfers the vibrations from the transducer to the tip.

Tip
➁
The tip is a hollow titanium tube that touches patient tissue. When active, the tip vibrates at an ultrasonic frequency, causing it to fragment tissue.
The tip has two pre-aspiration holes ➀, one on either side, which help to keep the tip clear and provide beer visibility at the surgical site.
Threads ➁on the end of the tip are for aaching the tip to the connecting body of the handpiece.
The tip is sterile and single use when in a sterile tip pack or can be used up to five (5) times if it is an extended use tip (EUT).
The single-use nosecone aaches to the handpiece, covers the connecting body, and holds the flue in place. It is sterile in a single use tip pack
and nonsterile in an EUT pack.
Integrated O-rings
The o-rings are integrated into the nosecone. They provide stability for the nosecone and prevent fluid leaks into the connecting body.

Flue
The single-use flue is a translucent silicone tube tapered at one end that provides a sleeve over the tip. Irrigation fluid flows through an irrigation
connection tube at one end of the flue and down the tip to the surgical site.
The single-use flue is sterile in a single use tip pack and nonsterile in an EUT pack.
Each tip size requires a tip-specific flue; therefore, you will find the tip-specific flue packaged with the appropriate tip.
Additional Handpiece Components
These components are essential in assembling a handpiece.
