It is configured by detachably mounting. By providing a filter or a check valve at the intake port 40, it is possible to prevent the inside of the closed cover from becoming a vacuum when suction is started, and further, when the suction is finished, dust and particles from the outside and evaporation generated inside the closed cover. This has the effect of preventing the leaked substance from leaking to the outside.

That is, as the filter that is detachably attached, a filter that can remove smoke, odor, and particles generated during laser irradiation to the treatment section is implemented.

As the filter, a known dust removal filter used for general air conditioning or dust removal, or a general adsorption filter suitable for removing odor or gas may be used. For example, activated carbon, ACF (fibrous activated carbon), a chemical adsorbent, an ion exchange resin, zeolite, activated alumina, or the like may be used. Further, the filter may carry a catalyst suitable for removing odor.

The action and effect of the filter can also be achieved by a structure in which the filter is attached to the suction port 2b of the closed cover 2.

Although details of the configuration of the suction device 20 in the configuration of the laser handpiece 1 are not shown in the drawings, it can be carried out by applying a known suction device in the technical field (for example, a trade name "". Whisper Liber 2" dental suction device pump JMDN:7072700 (made by Yoshida Co., Ltd.).

In addition, below, the application example of the suction device 20 used for implementation is shown.

The suction device 20 includes a vacuum motor for vacuum suction. The operating principle is as follows.
When the operation switch of the suction device 20 is turned on, the motor starts rotating, and the motor rotates the turbine of the blower connected by the belt.

The negative pressure generated by the rotation of the turbine causes the suction device of the dental unit to perform suction, and the sucked air is filtered by, for example, a suction device filter (not shown) and exhausted.

It is possible to confirm the position of the treatment part by providing the small camera 30 for recognizing.

Further, at the time of laser treatment, the patient, the practitioner, and persons in the vicinity need to wear protective glasses to protect their eyes from the scattered light of the laser, but the sealing cover 2 absorbs the scattered light of the laser. Since it is made of a material having properties, it is possible to omit wearing glasses.

Therefore, as a result of performing the required treatment based on the above-described action and effect, it is possible to perform the treatment alone by the practitioner without the need for a nurse during the treatment due to the simplicity of the operation.

Although the sealing cover 2 in the above-described configuration has been described in the embodiment in which it is attached to the head portion 11, it has a detachable configuration (not shown) so that it can be repeatedly used and is disposable. It is also possible to do so.

That is, it is considered that smoke, odor, and particles are generated during the operation such as incision, excision, and transpiration with the laser device, and these particles adhere to the inside of the closed cover 2. Therefore, the molding material of the closed cover 2 has heat resistance and sterilization resistance.
