The ideal weight distribution of the SWERV³ handpiece enables the clinician to achieve proper
balance. For ideal positioning, the handpiece of the ultrasonic should be balanced in the web of the
hand between the thumb and index finger⁹. SWERV³ is equipped with a silicone handpiece rest that enables use of a relaxed grasp to eliminate undesired tension in the fingers.⁶ The ergonomic design
of Hu-Friedy™ inserts reduces finger pinching for a light clinical touch and enhanced tactile sensitivity.
This, in conjunction with a lightweight flexible cord, can aid in the reduction of muscle strain during treatment.
