Components Description
1
Tip The titanium alloy tip is unique to each handpiece, having a designated thread to
minimize the possibility of attaching it to the wrong handpiece.
2 Shroud Black heat resistant shrouds that are interconnected by snap-in push fittings with
the exception of the laparoscopic handpiece which has a screw thread joint. The
shrouds cover one or two titanium alloy parts:
• All handpieces contain a tip.
• Angled handpieces also include an angled extension.
These titanium alloy parts are fitted with screw threads and are removable for
cleaning and sterilizing using the appropriate handpiece wrench set.
3
Handle Contains the piezoelectric transducer which includes an array of piezo ceramic
elements to convert the power signal from the CUSA NXT Console into mechanical
vibration at 24 kHz or 35 kHz depending on the handpiece type.
4 Piezoelectric Transducer
(Internal) Generates negligible heat and requires no external cooling system. Each
handpiece conforms to the highest levels of electrical safety. All the handpieces
are Type CF (Cardiac Floating) with a patient leakage current of less than 10 A.
Note that the rear section of the handpiece does not contain any user-serviceable
parts. Under no circumstance should it be tampered with.
5
Flue The tip of the handpiece is covered by a one-piece or two-piece clear flue to
protect tissues around the tip and ensure clarity of view during operation.
