Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a handpiece hood for a laser light therapy device, and more specifically, to a handpiece hood that allows the beam position of an infrared laser beam to be visually observed.

[Conventional technology]

In recent years, remarkable progress has been made in laser light therapy devices, such as optical stimulation therapy devices that use laser light instead of acupuncture and acupuncture in acupuncture point stimulation therapy, and surgical incision scalpel devices.

Various gas lasers and solid-state lasers are used for treatment, but recently YAG laser light, which has relatively strong thermal stimulation and penetrating power, has been used frequently. As is well known, this YAG laser light is generated using a mixture of yttrium oxide and aluminum oxide, and its wavelength is approximately 1.06 μm, making it an infrared laser light that cannot be seen as it is.

Therefore, when actually using this YAG laser light in a laser light therapy device, etc., an appropriately colored light beam is used as a guide light, and by irradiating it together with this guide light, the invisible YAG laser light hits the target. This allows the location to be visually checked.

[Problem to be solved]

However, when using guide light, a device for generating the guide light and a device for sending out the guide light as a luminous flux almost the same as the YAG laser light are required, which has the disadvantage that the optical stimulation therapy device becomes complicated and expensive.

[Means for solving problems]

This idea was made to solve the above-mentioned problem, and a suitable infrared visible plate that is colored by infrared rays such as YAG laser light is movably installed inside the handpiece hood, and this coloring is used as a guide. This allows the beam position of the YAG laser beam to be visually checked.

[Effect]

When the YAG laser light hits the infrared visible plate, it appears colored, so the beam position of the YAG laser light can be immediately determined, and when the YAG laser light is actually irradiated to the affected area or acupuncture points, the infrared visible plate is moved to the retracted position. Since the treatment is carried out in a controlled manner, the therapeutic effect of the YAG laser light is not diminished.

〔Example〕

An embodiment of this invention will be described with reference to FIGS. 1 and 2.

A substantially frustoconical hood 11 is attached to the tip of the hand piece 1 of the optical stimulation therapy device, and at least one viewing window 1 is provided on the peripheral wall of the hood 11.
1A is provided.

Near the open end of the hood 11, two slide wires 2 extend in parallel with one diameter position in between.
1 and 21 are slidably attached to the hood 11, and these slide wires 21 and 21 carry the infrared visible plate 2. Note that the reference numeral 21A is a knob attached to both ends of the slide wires 21, 21.

The infrared visible plate 2 is, for example, an IR viewer made by NEC Corporation or an IR made by Eastman Kodak.
Any device that develops color and becomes visible to the eye when exposed to infrared rays, such as an Infra-red ray viewer such as Phospher, may be used.
I am trying to confirm this through.

Note that if the entire hood 11 is made of a transparent material, there is no need for a viewing window.

The solid line in FIG. 1 or 2 indicates the position of the infrared visible plate for visual confirmation. When the YAG laser beam hits the infrared visible plate 2 at point P, the point P shines green, and the YAG laser beam Beam position can be known immediately and accurately. After confirming this beam position, when actually irradiating the affected area or acupuncture point with this YAG laser beam, move the infrared visible plate 2 to the retracted position by holding the knob 21A as shown by the broken line in Figure 2. Let me do it. In this way, the YAG laser beam will not be obstructed by the infrared visible plate 2.

FIG. 3 shows another embodiment of this invention.

In this embodiment, the infrared visible plate 2 is attached to the tip of an arm 22 that is rotatable around a rotation axis 23 outside the hood 11. Arm 22
A presser lever 24 is fixed to the other end, and the entire lever receives clockwise torque from a wire spring 25 and is normally placed in the retracted position shown by the broken line.

When it is desired to detect YAG laser light, the arm 22 is rotated by pressing the holding lever 24 with a finger, and the infrared visible plate 2 is moved to the central axis position of the hood 11. Also, when actually starting the treatment, please use the control lever 2.
Just remove your finger from 4. The arm 22 is a wire spring 25
It returns to the retracted position due to its elasticity and does not interfere with the YAG laser beam irradiation.

Although not shown, in the first embodiment as well, if a coil spring is provided between the outer periphery of the hood 11 and the knob 21A, the infrared visible plate 2 can be retracted when the hand is released. It's easy to do.

It goes without saying that when a condensing lens system is provided on the laser beam emitting end side, the infrared visible plate is placed at the focal position on the optical path of the laser beam.

〔effect〕

According to this idea, when YAG laser light hits an infrared-visible plate, it appears colored;
The beam position of the YAG laser light can be immediately determined, eliminating the need for a guide light, and eliminating the need for various guide light devices, making the optical stimulation device as a whole simple and inexpensive. Since the infrared visible plate can be moved to the retracted position during irradiation, the therapeutic effect of the YAG laser light is not diminished.
