Dental handpiece set

Abstract

There is disclosed a dental handpiece set which comprises a handpiece housing, a power supply module detachably coupled to one end of the housing for supplying power to operate the handpiece, a motor unit which is selected from a set of different types of motors and which is removably mounted in the housing as an exchangeable motor unit, and a drive train extending within the housing to an opposite end of the housing at which a dental implement can be mounted to be driven by the drive train when the motor unit is mounted in the housing and is coupled with the power supply module. The end of the housing which is detachably coupled with the power supply module is adapted removably to receive the selected motor unit so that a housing of the unit is secured within the housing against rotation. At least two different types of motor unit e.g. an air driven motor and an electric motor, are provided to be mounted selectively in the housing according to operating requirements for the handpiece, each motor unit being arranged so as to be capable of being received by the housing via said one end thereof and being adapted for coupling with the power supply module. Accordingly, the dental handpiece set enables any desired combination of elements to be obtained to suit any available power supply module.
