Description

[Detailed description of the invention] Industrial applications The present application relates to a dental treatment device.

Conventional technology and its problems Conventionally, semiconductor laser treatment instruments perform treatment by applying stimulation to the skin by applying a semiconductor chip to the skin using the output of an oscillator, and incisional surgery is performed by energizing the blade with the output of a high-frequency oscillator. A therapeutic scalpel, a root canal length measurement instrument that uses the output of a pulse oscillator to energize a measuring needle, or a root canal cleaning tool or a tartar removal tool that uses the output of an ultrasonic generator to apply electricity to a vibrating element. BACKGROUND OF THE INVENTION Dental treatment instruments are known in which a handheld tool is provided with an electric part operated by an actuating source.

In addition, the cutting bar is provided with a piping system inside the cutting bar at the tip, and a transmission shaft for rotating the cutting bar R, a gripping member having a female connecting part at the rear end of the gripping member, and a piping system inside the entire male connecting part at the tip, It is equipped with an air motor or an X-motion micromotor, and a joint member from which a flexible hose connected to a fluid supply line is led out at the rear end, and the connecting parts are rotatably connected to a detachable hook. There are also motor-driven dental treatment instruments that connect the output shaft of the motor and the transmission shaft.

By the way, both of the above-mentioned dental treatment instruments are installed in a dental unit treatment chair or a technician cabinet, but in the case of a rotary treatment instrument equipped with an electric part, an electric operation source is required. Since the latter must be connected to a fluid supply source and a power source separately from the treatment equipment, the mounting structure for the dental unit, treatment chair or technical cabinet becomes complicated, and there is a risk of failure. In some cases, flexible hoses may become entangled with each other, making it difficult to pull out treatment instruments. A connecting part connectable to a joint member provided with a motor, a starter connected to the output shaft of the motor of the joint member in a connected state, and an electric actuating source operated by the electric power are provided at appropriate locations in the technical cabinet. Provide auxiliary equipment so that the electrical and fluid systems from the supply source to the coupling members can be used in common,
