In addition, there is a conductive system inside, a piping system, pressurized fluid operating parts such as an air turbine that drives the cutting bar with pressurized fluid in this piping system or a spray nozzle that spews out mist, and a lamp that lights up when energized to illuminate the affected area. Alternatively, a gripping member is provided with a heater for heating the fluid ejected from the nozzle, has a connecting portion at the rear end, a female connecting portion at the tip, a piping system and a conductive system inside, and the rear end is A dental treatment instrument such as a dental handpiece or a syringe, which is composed of a fluid supply source and a joint member formed by leading out a flexible hose connected to a power source, and the connecting parts are rotatably connected to a detachable gap. It is also known, for example, from Japanese Patent Application Laid-Open No. 58-4546.

By the way, all of the above-mentioned dental treatment instruments are used by being installed in a medical unit, a treatment chair, or a technician cabinet. In the case of a treatment instrument with a moving part, since it requires an oscillator output, it must be connected to a fluid supply source and power source separately from the treatment instrument with a pressurized fluid operating part. The mounting structure for the unit, treatment chair, or technician cabinet has become complicated, and not only is this a common problem that can lead to problems, but also defects such as flexible hoses getting tangled with each other and making it extremely difficult to pull out treatment equipment. have
