Document Type and Number:
WIPO Patent Application WO2002069315
Kind Code:
A3
Abstract:
An adapter (30) for use with a piezoelectric and/or magnetostrictive ultrasonic unit can be coupled between the handpiece (12a) and the cable (12b). The adapter (30) includes a symmetrically oriented flow path (38a, 38b) with offset ends to mate with the handpiece and the cable respectively. The adapter (30) also includes a rotary electrical connection facilitating the transfer of energy from the cable (12b) to the handpiece (12a) while the handpiece is being rotated. The rotary connection of the adapter van be integrated into either of the handpiece or the cable termination.
