Novel "Wands” Measure Temperature During Arthroscopic Surgery

New adjustable probes provide surgeons with accurate, real-time temperature measurements of circulating fluid during arthroscopic surgeries.

The Ambient ArthroWands are comprised of a portfolio of radiofrequency (RF) devices that include the Ambient Super MultiVac 50, the Ambient Super TurboVac 90, the Ambient CoVac 50, and the Ambient CoVac 70, which are all designed to monitor the temperature of the circulating fluid in real time. When paired to the ArthroCare Quantum 2 controller system, the thermocouple technology allows surgeons to view current temperature measurements of the saline fluid in the shoulder and knee.


An adjustable set point allows the surgeon to set an alarm at the temperature he or she feels is appropriate; visual and audible alarms warn the surgeon if the temperature reading reaches the user-selected alarm set point. The alarm feature also acts as a reminder, encouraging the surgeon to check if adjustments should be made to flow or suction throughout the duration of the procedure. The Quantum 2 System Controller continually displays the real-time, operative environment temperature of the circulating fluid, as measured by the Ambient wands. The Ambient ArthroWands are a product of ArthroCare (Austin, TX, USA).

"The introduction of our complete Ambient Collection is a significant next step in the continuing growth and development of our ArthroWand family of products for shoulder and knee repair,” said Scott Schaffner, senior vice president and general manager of ArthroCare Sports Medicine. "We've now introduced reliable temperature monitoring to arthroscopic procedures. The Ambient collection is easy to use and the system provides surgeons with real-time information. It's something we know many surgeons have been asking for and we're excited to be able to deliver.”

"Operative fluid temperatures during arthroscopic surgery depend on a number of variables, including flow rates,” added Peter Millett, M.D., of the Steadman Clinic (Vail, CO, USA). "For me, the Ambient wand has become an integral tool for arthroscopic procedures, because it allows me to constantly verify that I'm operating within a desired thermal range.”
