所要の治療作業に供している。2. Description of the Related Art Conventionally, a flexible hose is led out to the rear end of a handpiece formed by connecting a joint member and a hand-held member in a rotatable and detachable manner, and the flexible hose is operated and controlled by a foot petal. Connected to a working medium supply source such as a pressurized air source, a water supply source, a power source or a suction source, and by stepping on the foot petal, the working element provided on the head of the hand-held member is supplied with the required working medium. A treatment device that supplies and treats by this is known, and at the time of treatment, by selectively connecting a plurality of hand-held members having preparatory performance to a joint member according to a treatment mode. ,
It is used for the required treatment work.
しかしながら、従来の治療装置において、継手部材を
共用するための手持部材の種類には、自ら制限を有す

のように、作動媒体源が異なる場合にも同様である。For example, in a cutting handpiece equipped with an air turbine in dental treatment, a handpiece using a ball bearing air turbine requires a pressurized air pressure of about 2 kg / cm 2 , whereas In the case of a handpiece using a turbine, a pressurized air pressure of about 4 kg / cm 2 is required, and when the working media have different capacities, the joint member cannot be shared. This also means a tooth cleaner that requires a mixing generator that mixes compressed air and powder, an electric knife that requires a high frequency power source, a scaler that requires an ultrasonic oscillator, and a semiconductor laser oscillator. The same applies when the working medium source is different, such as a required laser treatment device.
