Abstract
A dental scaler is provided which has a control unit and a handpiece assembly linked to the control unit by a conduit carrying fluid and electrical power. The handpiece assembly includes a conduit connector secured to an end of the conduit remote from the control unit and an autoclavable handpiece removably securable to the conduit connector. The connector and handpiece have slidably connectable bodies, each having mating fluid and electrical connectors. The handpiece connector body includes a check valve to prevent rearward flow of water. The conduit connector body includes a check valve and a double fluid tight seal. The use of the two check valves and two seals reduces the possibility of fluid leaking from the back of the handpiece or from the connector. The conduit connector body is received in a sleeve of the handpiece. The connector has a finger which is received in an axial slot of the handpiece sleeve. The finger and slot form a size-on-size fit to frictionally hold the conduit connector and handpiece together.
