Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for light irradiation, for example, an optical working device capable of automatically cleaning dirt on a tip for light irradiation of a handpiece.

2. Description of the Related Art Conventionally, a handpiece irradiates a target with light by a user holding the handpiece. For example, laser light is emitted from the light emitting tip of the handpiece. This tip is easily stained with dust. Therefore, the user cleans the tip of the handpiece by removing dirt with absorbent cotton impregnated with ethyl alcohol.

PROBLEM TO BE SOLVED BY THE INVENTION In the conventional apparatus, the user always cleans the tip of the handpiece by himself / herself as described above, so that inconvenience is always caused in use. For this reason, it has been desired that the apparatus itself be provided with a function of automatically cleaning the tip of the handpiece.

SUMMARY OF THE INVENTION An object of the present invention is to provide an easy-to-use optical working device that automatically performs cleaning of a handpiece light-emitting end, which has been conventionally performed by a user, and saves time and effort of the user.

SUMMARY OF THE INVENTION The present invention is directed to an optical working device described in the claims.

Means for Solving the Problems The present invention exemplifies a semiconductor laser local treatment apparatus as shown in FIG.

The storage portions 2 and 3 of the main body 1 store handpieces 4 and 5 which are light irradiation devices. The detecting means (the handpiece detector 43) is provided in each of the storage sections 2, 3, and detects that the handpieces 4, 5 are stored.

Cleaning means (in the embodiment, the cleaning unit shown in FIG. 2)
30) cleans the laser beam emitting tip 29 of the handpiece in the storage sections 2 and 3.

The treatment is performed by irradiating the laser via the handpieces 4 and 5. After use, store the handpieces 4,5 in the storage sections 2,3,
The detection unit detects whether or not the sheet is stored. Then, the laser beam emitting end portions 29 of the hand pieces 4 and 5 are cleaned by cleaning means arranged in the storage sections 4 and 5.

Embodiment 1 As an embodiment of the present invention, a semiconductor laser local treatment apparatus shown in FIG. The two handpieces 4,5 are connected to the main body 1 by cords 6,7. This laser local treatment device is used, for example, for relieving pain due to muscle or indirect inflammation.

[Main Body 1] The main body 1 contains a laser oscillation power supply, a control circuit therefor, and the like (not shown). The operation unit 8 includes an output meter 9, a counter 11, a switch 12, various adjustment knobs 13 to
15, a main switch 16, abnormal lamps 17 to 19, and a laser oscillation switch 20 are provided.

[Handpieces 4 and 5] The handpieces 4 and 5 have the same shape. The handpieces 4 and 5 have heads 25 and 26 and grippers 27 and 28, respectively. The heads 25 and 26 are provided with a laser light emitting tip 29, in which a semiconductor laser element (not shown) is provided.
Is provided. The tip 29 has a cover glass 29a
have.

The cover glass 29a serves to protect an internal semiconductor laser element (not shown) from dust and dirt.

[Storage Unit] The storage units 2 and 3 are disposed on the left and right sides of the main body 1. The storage section 2 stores the handpiece 4. The storage section 3 stores the handpiece 5. For this reason, the storage portions 2 and 3 are provided with concave portions 21 and 22, respectively.

 Please refer to FIG.

Since the storage sections 2 and 3 are symmetrical, the storage section 2 shown in FIG. 2 will be described as a representative.

The cleaning unit 30 is detachably provided in the recess 21. The head 25 of the handpiece 4 is located in the recess 21.
A support 31 for supporting the vehicle is provided. The grip portion 27 of the handpiece 4 is detachably fitted in the set portion 32 of the storage portion 2. When the handpiece 4 is set in the storage section 2, the tip portion 29 of the head 25 is
It passes through 34 and hits the upper part of the cleaning unit 30.

[Cleaning unit] Referring to FIG.

The cleaning unit 30 is an ultrasonic cleaner and includes a tank 40, an ultrasonic oscillation source 41, a cleaning liquid 42, and a handpiece detector 43. By operating the ultrasonic oscillation source 41, the tip portion 29 is cleaned.

As the cleaning liquid, for example, ethyl alcohol or the like is used.

The handpiece detector 43 is a touch sensor or the like, and detects whether the handpiece 4 is stored in the storage section 2 and sends it to the control circuit. The control circuit sends a signal to the ultrasonic oscillation source 41 for a certain period of time when stored.

[Operation] Next, the operation will be described with reference to FIG.

The main switch 16 shown in FIG. 1 is turned on to operate the control circuit, and the detector 43 shown in FIG. 2 detects whether the handpieces 4, 5 have been securely stored in the storage sections 2, 3.

When both the detectors 43 notify the control circuit that the handpieces 4 and 5 are correctly stored, the control circuit starts operating the ultrasonic oscillation source 41 of the cleaning unit 30. Thereby, the tip portion 29 of the handpiece 4 is ultrasonically cleaned. After cleaning for a certain period of time, the ultrasonic oscillation source 41 is stopped.

When the cleaning is completed, the necessary handpiece 4 or 5 is removed from the storage section 2 or 3. Then, in order to irradiate the affected part of the patient with the laser beam, the tip of the handpiece 4
29 parts are applied to the affected part, and the laser oscillation switch is turned on to irradiate a laser beam.

After the laser irradiation, the handpiece is returned to the storage section. The handpiece returned to the storage section is detected by the detector 43, and upon receiving the detection signal, the control circuit activates the ultrasonic cleaning source again.

The main switch 16 is turned off, the control circuit is turned off, and the process ends.

Embodiment 2 Referring to FIG.

The cleaning unit 130 is provided with a hole 134 into which the tip 29 is inserted. The unit 130 has a tank 140, a winding roll 160, a winding motor 161, and rollers 162 and 163.

The tank 140 contains a cleaning liquid 142. The cleaning paper 170 is wound around the roller 171. The cleaning paper 170 is wound around a winding roll 160 by a motor 161. The cleaning paper 170 absorbs the cleaning liquid 142 and cleans the tip 29 while moving in the direction of the arrow. 143 is a handpiece detector.

Embodiment 3 As shown in FIG. 6, a sponge 231 is contained in the cleaning unit 230, and the cleaning liquid is impregnated therein. The tip portion 29 of the head 25 is designed to slightly enter the sponge 231. 243 is a detector.

Incidentally, the present invention is not limited to the above embodiment. For example, the cleaning unit and the detector may be separate. In addition, the detector may be located outside the storage section, in other words, it is only necessary to detect whether the handpiece is stored in the storage section. The detector may be of a non-contact type. The handpiece may be of a pen type.

The present invention is not limited to the semiconductor laser local treatment device,
It can also be applied to laser processing equipment and the like. Not only laser light but also other light may be used.

Advantageous Effects of the Invention According to the present invention, it is possible to wash a tip emitting light only by storing a light irradiation device, prevent a decrease in light output due to dust or dust at the tip, and improve hygiene for an affected part. Can be kept.
