Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a laser device used particularly for medical purposes.

[Prior Art] Medical laser devices that are generally used in surgical operations etc. guide laser light generated by a laser source to a handpiece through a light guide path formed from an optical fiber, an articulated manipulator, etc. It is designed to emit light from the radiator to irradiate the area to be operated on.

In such a laser device, a YAG laser, a carbon dioxide laser, or the like is used as a laser source. The laser light output from these laser sources cannot be seen with the naked eye. Therefore, there was a risk that it would not be possible to confirm whether or not laser light was being emitted from the handpiece at the tip of the light guide.

In order to eliminate this kind of danger, when the laser source is activated to output laser light, a warning sound generator is linked to generate a warning sound.
As shown in the publication, a vibration device is linked to the operation of the laser source, and the vibration device causes the handpiece to vibrate, thereby informing the operator who grips the handpiece that laser light has been output.

[Problems to be Solved by the Invention]However, the above-mentioned prior art requires a warning sound generating device and a vibrating device, and furthermore, it requires control to link these devices to the operation of the laser source. It is an object of the present invention to provide a laser device in which it is possible to reliably know that laser light has been output from a laser source without complicating the entire system since it also requires a circuit.

[Means and effects for solving the problems] This invention has the following features:
The laser beam output from laser generation R2 is sent to handpiece 1.
An optical member 6 for separating a part of the laser light is provided in the light guide path 11 leading to the laser beam 3, and the display part 9 irradiated with the laser light separated by the optical member 6 emits fluorescence. 9 to confirm that the laser source 2 is operating.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2 (-
I will explain. The laser device shown in FIG. 1 includes a main body 1. The laser device shown in FIG. Inside the main body 1 is a first laser source 2 that emits a cauterizing laser beam such as a YAGL laser;
A second laser generation source 3 that emits guide light G, such as a He-Ne laser, is housed. The 1/- laser light output from the first laser source 2 is transmitted to the first laser beam forming the light guide path.
After being reflected by the reflecting mirror 4 and the gicroic mirror 5, it is focused by the condensing lens 10 and enters the first beam splitter 6 as an optical member. The first beam splitter 6 is formed to separate, for example, reflect, a part of the laser beam, and the part of the laser beam reflected here is reflected by the second reflecting mirror 8 and is reflected by the first beam splitter 6. The light enters the display section 9. This first display section 9 is designed to emit fluorescence when laser light is incident thereon.

On the other hand, the guide light G output from the second laser source 3 passes through the guichroic mirror 5 and the first beam splitter 6. The laser light and the guide light G transmitted through the first beam splitter 6 are the main body 1.
The light enters the connecting portion 8a provided on the end face of the. A connector 12 provided at one end of an optical fiber 11 constituting a light guide path is detachably connected to this connecting portion 8a. A hand piece 13 is connected to the other end of the optical fiber 11. In this hand piece 13, the optical fiber 1 is
Among the laser light and guide light G emitted from the hand piece 1, a part of the laser light is transmitted to the second light beam provided in the hand piece 13.
is reflected by the beam splitter 14 of the hand piece 1.
The light enters the second display unit 14 provided on the side surface of 3. Then, this second display section 15 emits fluorescence.

According to the laser device having such a structure, when the first single laser source 2 is activated to oscillate a cauterizing laser beam, a part of this laser beam is transmitted to the first laser beam within the main body 1. The light is reflected by the beam splitter 6 and causes the first display section 9 to emit light. Further, within the hand piece 13, a portion of the laser light is reflected by the second beam splitter 14 and enters the second display section 15, causing the second display section 15 to emit light. Therefore, by checking whether the first display section 9 or the second display section 15 is emitting light, it is possible to reliably know whether or not the first laser source 2 is operating. The danger of erroneous irradiation with laser light can be eliminated.

FIG. 3 shows another embodiment of the invention. This embodiment uses an articulated manipulator 17 as a light guide instead of the optical fiber 11 of the above embodiment. In other words, this multi-joint Z nubulator 17 has a bendable guide body 18 provided with a reflector 19 at each joint, one end of the J bipedal guide body 18 is connected to the connection part 8 of the main body 1, and the other Handpiece 13 is provided at the end)
) No. 1. The main body 1 and the handpiece 3 are provided with first and second display sections 9.15 as in the first embodiment.

In each of the above embodiments, the display section may be provided only on either the main body or the handpiece. Further, the display section may be provided in a portion other than the main body and the hunt piece, and in short, it may be provided in the light guide path.

[Effects of the Invention] As described above, the present invention provides an optical member that separates a part of the laser light in the light guide path that guides the laser light output from the laser source to the handpiece, and this optical member The display section is made to emit light using the separated laser beams. Therefore, since it is possible to know reliably and easily whether the laser source is operating from the display section, it is possible to prevent erroneous irradiation of laser light. Also,
By irradiating the display with a portion of the laser light output from the laser source, it is possible to tell that the laser source is operating, so the laser light is not output by the conventional 'R3 sound or vibration. Not only is the structure simpler than that of the conventional method, but it is also advantageous in terms of cost.
