One end of the light guide 155 is formed in the recess 150a, and a guide light irradiation port 156 is formed at the other end. Thereby, the light beam L emitted from the light source 122e of the turbine hose 122 is irradiated to the affected area from the guide light irradiation port 156, and the periphery of the affected area can be illuminated brightly.

  Further, the dental laser device 150 has a flow path for air turbine driving air DA, air A, and water W supplied from the turbine hose 122 and a flow path for discharging the air turbine driving air DA to the turbine hose 122. Have. That is, the dental laser device 150 includes an air turbine driving air introduction path 157a, an air turbine driving air discharge path 157b, a water flow path 157c, and an air flow path 157d.

The other end of the air turbine drive air introduction path 157 a and the other end of the air turbine drive air discharge path 157 b communicate with the air chamber 158. That is, the air turbine driving air introduction path 157 a and the air turbine driving air discharge path 157 b communicate with each other via the air chamber 158.
The heat sink 151b is in contact with the air chamber 158. As a result, the heat generated by the laser diode 151a is radiated to the air chamber 158 via the heat sink 151b.
In addition, a liquid outlet 153 is formed on the end side of the water flow path 157c. Similarly, an air outlet 154 is formed on the end side of the air flow path 157d.

  The air turbine driving air introduction path 157a is bifurcated in the middle, and an air supply detecting means 152 is attached to one end.

  The chip 151d, the liquid jet port 153, the air jet port 154, and the guide light irradiation port 156 are formed on the distal end side (the side opposite to the side where the concave portion 150a is formed) of the dental laser device 150. The liquid jet port 153, the air jet port 154, and the guide light irradiation port 156 are disposed in the vicinity of the chip 151d.

The opening positions of the light guide path 155, the air turbine driving air introduction path 157a, the air turbine driving air discharge path 157b, the water flow path 157c, and the air flow path 157d formed in the recess 150a are as follows: When the dental laser device 150 and the turbine hose 122 are connected, the light source 122e, the air supply passage 122a for driving the air turbine, the water supply passage 122b, the air supply passage 122c, and the air exhaust for driving the air turbine, respectively. The position is opposite to the path 122d. That is, the opening of the light guide path 155 faces the light source 122e, the opening of the air turbine driving air introduction path 157a faces the opening of the air turbine driving air supply path 122a, and the opening of the air turbine driving air discharge path 157b.

Although not shown, the turbine hose 122 is provided with a plurality of seal mechanisms. Thereby, when the turbine hose 122 and the dental laser device 150 are connected, the air supply path 122a for driving the air turbine 122, the water supply path 122b, the air supply path 122c, and the air exhaust path 122d for driving the air turbine. And are independent of each other. Therefore, for example, the water in the water supply path 122b is prevented from leaking into the air supply path 122a for driving the air turbine.

Next, the usage method and operation | movement of the dental laser apparatus 150 are demonstrated using FIG. 2 and FIG.
As described above, the dental laser device 150 is detachable from the turbine hose 122 to which the air turbine 131 is normally connected. When using the dental laser device 150, the turbine hose 122 is removed from the air turbine 131 and connected to the dental laser device 150. At this time, the tip of the turbine hose 122 is inserted into the recess 150 a of the dental laser device 150.

Then, when it is desired to irradiate the affected area with a laser beam, the dentist steps on the foot controller 140. Thereby, the air turbine driving air DA is supplied from the turbine hose 122 to the dental laser device 150 through the air turbine driving air supply passage 122a. The air turbine driving air DA supplied to the dental laser device 150 flows into the air turbine driving air introduction path 157a. A part of the air turbine driving air DA is supplied to the air supply detecting means 152 and the rest is supplied to the air chamber 158 by the branch provided in the air turbine driving air introduction path 157a. Since air turbine driving air DA is supplied to the air supply detection means 152, air pressure is applied to the air supply detection means 152, so that the air supply detection means 152 applies the air pressure to the dental laser device 150. It is detected that the air turbine driving air DA is supplied.
When the air supply detection means 152 detects the air turbine driving air DA, a detection signal is transmitted to the controller 151f, and the controller 151f energizes the laser diode 151a. Thereby, a laser beam is irradiated from the laser diode 151a, passes through the laser light guide 151c, and is irradiated from the chip 151d toward the affected part.
At this time, water W is supplied from the turbine hose 122 to the dental laser device 150, and the water W passes through the water flow path 157 c in the dental laser device 150 and is ejected from the liquid ejection port 153. Further, air A is also supplied from the turbine hose 122 to the dental laser device 150, and this air A passes through the air flow path 157 d in the dental laser device 150 and is ejected from the air ejection port 154.

  On the other hand, the air turbine driving air DA supplied to the air chamber 158 passes through the air turbine driving air discharge path 157 b and is discharged to the air turbine driving air exhaust path 122 d in the turbine hose 122. Here, since the heat sink 151 b is in contact with the air chamber 158, the heat generated by the laser diode 151 a is conducted to the air chamber 158, so that the air turbine driving air DA passes through the air chamber 158, so that the laser diode The heat generated by 151a can be conducted to the air turbine driving air DA. That is, the air turbine driving air DA can cool the laser diode 151a.

Further, the foot controller 140 can output a control signal S corresponding to the depression amount of the dentist. That is, the foot controller 140 can output a plurality of values, not just a binary value of ON / OFF. When such a foot controller 140 is used, the instantaneous flow rate of the air turbine driving air DA supplied by the turbine hose 122 is not a constant value, and a plurality of instantaneous flow rates can be supplied. In the present embodiment, as the foot controller 140 is depressed, the instantaneous flow rate of the air turbine driving air DA supplied by the turbine hose 122 can be increased.
The dental laser device 150 can detect not only a simple ON / OFF binary value by the air supply detection means 152 but also various instantaneous flow rates (air pressure in the present embodiment). Therefore, not only the binary value corresponding to ON / OFF from the air supply detection unit 152 but also various values from the air supply detection unit 152 are input to the controller 151f. The controller 151f can change the voltage applied to the laser diode 151a in accordance with the input value from the air supply detection means 152. In the present embodiment, as the value input from the air supply detection unit 152 increases (that is, as the foot controller 140 is stepped on), the voltage applied to the laser diode 151a increases and the output of the laser beam increases.

  The dental treatment unit 100 and the dental laser device 150 configured and operated in this way are lasers by the dental laser device 150 depending on the presence or absence of air turbine driving air DA that is compressed air supplied to the dental laser device 150. By switching between irradiation and non-irradiation of the beam, there is no need to provide a dedicated foot controller for operating the dental laser device 150, so that the dentist's feet are clean and the working environment can be improved.

  Further, the output of the laser beam emitted from the laser irradiation mechanism 151 of the dental laser device 150 is adjusted according to the instantaneous flow rate detected by the air supply detection means 152, so that the laser can be operated only by operating the foot controller 140. Since the beam output can be changed, the usability of the dental laser device 150 can be improved.

  Furthermore, since the air supply detection means 152 is a pressure-sensitive element, the structure of the air laser driving air DA is simpler than the case where the air turbine driving air DA is detected based on the instantaneous flow rate or flow velocity. Can be improved.

Furthermore, since the laser diode 151a of the dental laser device 150 is cooled by the air turbine driving air DA, the temperature rise of the dental laser device 150 itself is suppressed, so that the usability of the dental laser device 150 is improved. Can be improved.
Further, by using air turbine driving air DA for cooling the laser diode 151a, the cooling mechanism of the laser diode 151a can be simplified as compared with the case of cooling using a Peltier element or the like. The size of the power supply 151e can be reduced.

Further, after the air turbine driving air DA supplied to the dental laser device 150 from the air turbine driving air supply passage 122 a of the turbine hose 122 passes through the dental laser device 150, the air turbine of the turbine hose 122 is used. By flowing into the driving air exhaust passage 122d, the dental laser equipment 150 is not filled with the air turbine driving air DA, and therefore, excessive air pressure is prevented from being applied to the air supply detecting means 152 and the like. The durability of the dental laser device 150 can be further improved.
Further, since the new air turbine driving air DA is always supplied to the dental laser device 150, the laser diode 151a is compared with the case where the air turbine driving air DA stays in the dental laser device 150. The cooling efficiency can be suppressed from decreasing.

  Further, since the dental laser device 150 includes the liquid jet port 153 and the air jet port 154, the affected part can be cooled, and dirt or the like in the vicinity of the affected part can be removed.

As mentioned above, although the form for implementing this invention was demonstrated, this invention is not limited above.
