Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laser treatment apparatus used for treatment of ears, nose, and throat in the field of otolaryngology.

[0002]

2. Description of the Related Art In recent years, attempts have been made to use a laser for treatment in the field of otorhinolaryngology.

[0003] For example, in the otolaryngology, there is a method of cauterizing the surface of the nasal mucosa using a carbon dioxide laser instead of using a drug as a treatment for hay fever. This method comprises a hollow light guide tube, a probe for irradiating forward, or a mirror for irradiating the side at the tip and using a probe for irradiating side, the energy of the laser beam emission end 2
About W to 5W (J / s), beam diameter φ1mm to φ at the emission end
Under the condition of 2 mm, the surface tissue of the nasal mucosa was 0.5 mm deep.
The transpiration was about 1 mm.

[0004]

However, this method has the following problems.

[0005] 1) Although a probe having a beam diameter of emitting end φ1 mm to φ2 mm is used, it is difficult to use the probe in combination with an endoscope, and the moving method and speed of the probe depend on the operator's empirical intuition. I couldn't get it.

2) The surface tissue of the mucous membrane of the nasal cavity is cauterized and evaporated, so that the effect of heat and pain are great, and anesthesia is required for treatment.

3) A hollow light guide tube is used as the light guide path of the probe, and its exit end face is open. Therefore, the inner peripheral silver mirror surface of the hollow light guide tube near the exit end face and reflection for side irradiation. The mirror surface is contaminated by smoke generated by tissue evaporation, which lowers the energy efficiency of the laser and is extremely difficult to clean. In general, this kind of probe could not be autoclaved due to optical problems.

[0008] The present invention has been made to solve the above problems, and does not cause pain or the like to a patient.
An object of the present invention is to provide a laser treatment device for otolaryngology that can be used not only for hay fever but also for the treatment of ears and throats without the need for anesthesia for treatment. I have.

[0009]

SUMMARY OF THE INVENTION The otolaryngological laser treatment apparatus of the present invention uses a knowledge of the onset mechanism of hay fever to reduce the wavelength of laser light having a good energy absorption rate to water or a hydroxyl group. The use of energy density enables the treatment of the ear, nose and throat without causing pain to the patient. First, the basic characteristics will be described.

[0010] The following is known about the onset mechanism of hay fever. In other words, when pollen adheres to the nasal mucosa,
When stimulated by it, the mucous membrane receptor reacts, and histidine, which is abundant in hemoglobin and stulin, is hydrolyzed,
It will spoil by synthesis and generate histamine. This histamine is toxic, but is usually inactive and present in muscle, pituitary, and other organs and does not cause superficial symptoms.

However, excessive release of histamine due to the effect of pollen causes allergic symptoms. That is, the presence of excess histamine in the blood vessels causes dilation of the capillaries, and as a result, the exudate oozes out of the nasal mucosa, and the nasal cavity is filled with the exudate, causing pollen such as "the nose slurs". The symptoms of the disease will come.
Therefore, if the exudate can be stopped, the symptoms of hay fever can be alleviated.

The present inventor has proposed that in order to stop this leachate,
By using laser light with a wavelength that has a good energy absorption rate to water or hydroxyl groups at a low energy density, this energy is absorbed by water or hydroxyl groups contained in mucosal tissue and heated, so that the mucosal tissue itself that emits exudate is thermally denatured. Or coagulation.

The hemostatic effect thus obtained has been confirmed experimentally, and the exudate due to the dilation of capillaries is also prevented. Further, a heat-denatured layer generated by laser light irradiation,
Since the coagulated layer is a tissue that is dead in terms of tissue, the above-described receptor reaction does not occur, and hay fever can be treated. In addition, since the energy density of the laser light is low, the pain of the patient is less likely to occur, and the treatment can be performed without anesthesia by adjusting the pulse of the laser light irradiation.

Further, such a technique can be applied not only to hay fever, but also to the inner wall of the ear hole or the inner throat where the exudate from mucosal tissues poses a problem. In particular, a laser treatment device for otolaryngology according to claim 1 is used for treatment of the ear, nose, and throat in an otolaryngology region, and a laser light source that generates laser light of a predetermined wavelength; A light guide path for guiding the laser light generated by the laser light source to the handpiece,
A laser treatment apparatus comprising a probe provided at the tip of the handpiece, wherein the light guide path of the probe is
Outer diameter 1mm ~ 3mm, length 80mm ~ 200m
m, and the tip has a conical shape with an apex angle of 70 ° to 90 ° or 95 ° to 110 °. From this probe, a wavelength of 2 to 4 μm and an energy density of 10 mJ to 100 mJ / Irradiation with a laser beam with a square mm / pulse and a pulse of 1 pps to 10 pps is performed to thermally denature or coagulate the inner wall of the ear canal, the mucous membrane of the nasal cavity, and the inner wall of the throat, that is, the mucosal tissue in this part.

This laser treatment device specifically defines a treatment device that embodies the above-mentioned features, and treats hay fever and other diseases of the ear, nose, and throat without causing pain to the patient. can do. In addition, since the tip of the probe has a conical shape with an apex angle of 70 ° to 90 ° or 95 ° to 110 °, laser light is radiated from the probe not only to the front but also to the sides as well. Without using an endoscope or the like, the laser beam can be applied to the nasal mucosa, which is the treatment site, for treatment.

Further, since the energy density is low and the pulse is appropriately adjusted, the degree of pain to the patient can be further suppressed, and anesthesia for treatment is not required.

According to a second aspect of the present invention, there is provided a laser treatment apparatus for otolaryngology, comprising:
The probe is characterized in that a moving sleeve which partially covers the outer periphery of the conical portion at the tip of the probe and is slidable in the axial direction of the probe is provided.

In this laser treatment apparatus, the irradiation range of the laser beam in the outer peripheral direction can be regulated by the moving sleeve, if necessary. Therefore, when bleeding occurs locally, it is possible to prevent the irradiation of a portion other than that portion.

A laser treatment device for otolaryngology according to claim 3 is used for treatment of ears, nose and throat in an otolaryngology region, and a laser light source for generating laser light of a predetermined wavelength; A treatment device comprising: a light guide path for guiding laser light generated by the laser light source to a handpiece; and a probe provided at a tip of the handpiece,
The light guide path of the probe has an outer diameter of 1 mm to 3 mm, a length of about 80 mm to 200 mm, a distal end portion curved at a predetermined curvature, and a distal end emission surface substantially aligned with the curved longitudinal axis center line. The probe is irradiated with a laser beam having a wavelength of 2 to 4 μm, an energy density of 10 mJ to 100 mJ / square mm / pulse, and a pulse of 1 pps to 10 pps from the probe to the inner surface of the ear canal, the nasal mucosa, It is characterized by heat denaturation or coagulation of the inner wall of the throat, that is, the mucosal tissue in this part.

In this laser treatment apparatus, the tip of the light guide path of the probe is not a cone as in the first aspect, but a column, and instead, a laser beam irradiated forward from the end face of the column. The tip of the light guide path of the probe is curved so that the direction is obliquely lateral to a certain extent from the axial direction of the entire probe.

Therefore, by directing the distal end emitting surface to the treatment site, it is possible to prevent the irradiation of the region other than the site.

According to a fourth aspect of the present invention, in the otolaryngology laser treatment apparatus according to any one of the first to third aspects, the probe is a solid light guide or a tip of a hollow light guide. And a solid light guide.

In this laser treatment apparatus, the structure of the probe is defined and is used as a solid light guide. Therefore, there is a problem that the inner surface of the silver mirror is peeled off by an autoclave like a hollow light guide tube. And can be autoclaved. Further, since the solid light guide is combined with the tip of the hollow light guide, the autoclave resistance is improved as compared with the case where the whole is made hollow.

According to a fifth aspect of the present invention, there is provided the laser treatment apparatus for otolaryngology, wherein the wavelength of the laser light is 2.94 μm. I do.

In this laser treatment apparatus, the wavelength of the laser beam is set to 2.94 μm, at which the energy absorption efficiency in water or the like is maximized. Can be produced most effectively.

[0026]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a laser treatment apparatus for ENT according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is an external view showing an example of a laser treatment apparatus for otolaryngology according to the present invention.

In this laser treatment apparatus 10, a laser beam is supplied to the handpiece 2 by a probe 1, which is a tip portion for emitting a laser beam, a handpiece 2, which holds the probe 1 in a detachable manner, a cable 3, and a cable 3. The apparatus includes a laser light source 4, a gas supply source 5 for supplying gas, and an apparatus main body 6 accommodating the laser light source 4 and the like.

Probe 1, handpiece 2, cable 3
Will be described in detail with reference to FIG.

The laser light source 4 has a wavelength of 2 to 4 μm.
An Er: YAG (erbium-yttrium-aluminum-garnet) laser that generates a laser beam having an oscillation wavelength of 2.94 μm, which coincides with the peak of the light absorption wavelength band of water, is used. The light source has the best energy absorption rate in water and is suitable as the laser light source of the present invention.

The gas supply source 5 is capable of generating compressed air or compressed inert gas.
For example, when generating air, a blower or a compressor is used, and when generating an inert gas, a gas cylinder or the like in which the inert gas is compressed and packed is used.

FIG. 2 is an enlarged vertical sectional view of a main part of the laser treatment apparatus of FIG. Therefore, the same portions are denoted by the same reference numerals, and redundant description will be omitted.

The probe 1 has a light guide path 1a serving as a light guide path for laser light, a moving sleeve 1b provided at the tip of the light guide path 1a, a coating tube 1c having a plurality of layers for protecting and coating the light guide path 1a, It has a holder 1d for holding the tube 1c, a flow hole 1e provided in the holder 1d, and can be detachably attached to the tip of the handpiece 2.

The handpiece 2 includes a rear cover 2a, a main body 2b, a cap 2c which is screwed to and removed from the front of the main body 2b, a convex lens 2d, and the like.

The cable 3 contains a light guide path 3a from the laser light source 4 and a gas transport pipe 3b from the gas supply source 5.

The light guide path 3a is composed of an optical fiber.
The body part 2 penetrates through the rear cover 2a of the handpiece 2.
b is inserted into the central portion of the probe 1b, and the laser light guided through the convex lens 2d is passed through the light guide path 1a of the probe 1.
And the laser light is emitted from the tip of the light guide path 1a.

The gas transport pipe 3b passes through the rear cover 2a of the handpiece 2 and is connected to the conduit of the main body 2b.
The tip of this conduit is the holder 1d of the mounted probe 1.
To the flow hole 1e provided in the
Reaches one of the interlayer gaps of the plurality of cladding tubes 1c.

Accordingly, air or an inert gas is supplied from the air supply source 5 to the handpiece 2 through the gas transport pipe 3b, passes through the gap between the cladding tubes 1c, and from the tip of the probe 1 as shown in FIG. It is squirted as shown by the white arrow.

Thus, in this laser treatment apparatus 10,
The probe 1 can irradiate a laser beam and eject air or an inert gas.

Here, the length L of the light guide path 1a derived from the probe 1 is set to be 80 mm to 200 mm. This length is defined as a length necessary for performing a treatment by inserting it into the ear canal, the nasal cavity, and the throat. By setting the length L, each treatment can be suitably performed.

Although the light guide path 1a and the probe 1 are straight in FIG. 2, they may be curved.

FIG. 3A is an enlarged front end view of an example of the probe used in the laser treatment apparatus shown in FIG. 1, and FIG. 3B is a front view thereof. Using these figures, the ear using the device of the present invention,
The treatment of the nose and throat will be described.

As shown in FIG. 3 (a), in the laser treatment apparatus of the present invention, the light guide path 1a is solid and its outer diameter D
Is 1 mm to 3 mm, and as described with reference to FIG. 2, the probe 1 has a length L of about 80 mm to 200 mm.
And the tip has a conical shape with an apex angle θ = 70 ° to 90 °.
m, energy density is 10 mJ to 100 on the irradiated surface
mJ / square mm / pulse, pulse 1 pps to 10 pps
Of laser light.

Thus, assuming that the light guide path 1a is solid,
There is little problem of contamination of the tip part like a hollow light guide path, and there is no problem of peeling of the silver mirror surface due to autoclave,
Can be autoclaved.

Assuming that the tip of the light guide path 1a is conical and the apex angle θ1 is 70 ° to 90 °, laser light is irradiated in an irradiation area S1 as shown in FIG. It can be seen that the light is also emitted in a direction perpendicular to the direction and further to the rear to a certain extent. Therefore, when such a light guide path 1a is inserted into an ear canal, a nasal cavity, or the like, if attention is paid only to the insertion depth into the ear canal, the nasal cavity, or the like, the laser can be applied to a treatment site such as the inner wall of the ear canal without considering a delicate direction. Light can be emitted, and there is no need to use an endoscope or the like.

The outer diameter D of the light guide path 1a of the probe 1 is 1 mm
The value of ３3 mm is suitable for the ear canal, nasal cavity, or the like to be treated. By doing so, each treatment can be suitably performed.

The reason for setting the wavelength of the laser beam to 2 to 4 μm is that, as described above, the absorption of water or hydroxyl groups is utilized to effectively heat the mucous tissue that emits exudate from the inner wall of the ear canal. This is for denaturation or coagulation. In this regard, when Er: YAG (erbium-yttrium-aluminum-garnet) having a wavelength of 2.94 μm is used, the absorption efficiency in water or the like is the highest, and the effect is also the best. In addition, Er: YSGG (erbium-yttrium-scandium-gallium-garnet) laser, Er, Br: YSGG (erbium-
Chromium-Yttrium-Scandium-Gallium-
(Garnet) laser can also be used.

The energy density at the irradiated surface is 10 mJ
The reason for using the laser light of １００100 mJ / square mm / pulse is to prevent the mucosal tissue that emits exudate from being affected by more than heat denaturation and coagulation, such as pain, transpiration, and incision. At this energy level, there is little pain to the patient. Furthermore, pulse 1pp
With s to 10 pps, the pain is less severe and the patient does not need to be anesthetized for treatment.

As described above, this laser treatment apparatus can be used for otolaryngology if the therapeutic effect can be expected by heat denaturation or coagulation of the mucosal tissue that emits exudate.
It can be used for any treatment of the nose and throat. In particular, the nose is effective for treating hay fever, the ear is effective for treating inflammation such as otitis media, otitis media, and otitis externa, and the throat is effective for treating polyps and the like.

The light guide path 1a comprises a core as a core, a clad covering the core, and a jacket covering the clad, like the solid light guide path for ordinary laser light. Includes the case of being coated with.

A moving sleeve 1b is further provided at the tip of the light guide path 1a as shown in the figure.

The movable sleeve 1b is fixed to an outer periphery of the light guide path 1a with an adhesive 1bd or the like.
A cylindrical moving part 1bb screw-fitted to the outer periphery of the fixed part 1ba by a screw part 1bc, and the moving part 1bb is rotated with the moving part 1bb screw-fitted to the fixed part 1ba. By doing so, the position of the moving part 1bb in the axial direction with respect to the fixed part 1ba can be slid.

On the opposite side of the screw portion 1bc of the moving portion 1bb, a window 1be is formed by cutting the cylindrical portion of the moving portion 1bb from the front end by a window angle θ3 shown in the figure. When located in the conical portion, this window 1b
Only the portion e allows the laser light in the irradiation area S1 to further reach the outside, and the other portions block the laser light from reaching the outside.

Therefore, it is desirable that the moving section 1bb is made of a laser light absorbing material or a laser light reflecting member. In addition, wall surfaces 3 such as the inner wall of the ear canal, the nasal mucosa, and the inner wall of the throat
When it is desired to irradiate the entire circumference of 60 degrees, the moving unit 1bb is moved to the position shown in FIG.
In (a), it may be moved to the left.

In this way, if necessary, as shown in FIG. 3 (b), the laser beam can be prevented from reaching the entire circumference from the tip of the light guide path 1a.
Unnecessary laser light can be prevented from reaching.
In addition, the window angle θ3 is set to be about 30 degrees to 180 degrees, and can be selected according to the treatment site.

It should be noted that the moving part 1bb is fixed with respect to the fixed part 1ba.
The means for enabling the sliding is not only a method using the screw fitting described above, but also a method using an O-ring described with reference to FIG. 4, a method using a slide groove and a projection, and the like.

FIG. 4 is an enlarged view of the tip of another example of the probe used in the laser treatment apparatus of FIG.

This probe is different from the light guide 1a of FIG. 3 in that the light guide path 1a 'has a cone-shaped apex angle θ2 of 95 to 110 degrees.

As described above, when the tip vertex angle θ2 is set,
As shown in the figure, the irradiation area S2 is more obliquely forward, and is different from the case where the apex angle θ1 is set. Such a light guide path 1a 'in the irradiation area S2 is used when the treatment site such as the inner wall of the ear canal becomes narrower as it goes forward.
Laser light can be irradiated in the vertical direction depending on the treatment site.

By appropriately selecting the apex angles θ1 and θ2 within the respective ranges, the irradiation directions to the front and a certain degree rearward of the light guide paths 1a and 1a 'in the irradiation areas S1 and S2 can be changed to almost all directions. It can be covered across and can accommodate treatment sites in various orientations.

The light guide path 1a 'is provided with a moving sleeve 1f of another mode.

The moving sleeve 1f has a fixed portion 1f.
a, the moving part 1fb, the adhesive 1fd, and the window 1fe, the fixed part 1ba and the moving part 1 of the moving sleeve 1b in FIG.
bb, adhesive 1bd, window 1be
The difference is that the slide engagement means of the fixed part 1fa and the moving part 1fb is an O-ring 1fc as shown in the figure.

Even if this moving sleeve 1f is used, the moving portion 1fb can be moved relative to the fixed portion 1fa by a desired sliding position,
Positioning and holding can be performed at the rotational position, and the same effect as the moving sleeve 1b in FIG. 3 can be exhibited.

These two types of light guide paths 1a and 1a 'may be properly used depending on the purpose of use.

FIG. 5 is an enlarged view of the tip of another example of the probe used in the laser treatment apparatus of FIG.

Light guide path 1 which is the tip of this probe
g is such that, as shown in the figure, the distal end is curved at a predetermined curvature, and the distal end emitting surface 1gb is configured to be substantially perpendicular to the curved longitudinal axis center line 1ga. Is different from the light guide path 1a.

The center line 1g of the linear section of the longitudinal axis of the light guide path 1g
The intersection angle α between c and the curved longitudinal axis center line 1ga is desirably about 60 to 120 degrees.

In this case, the tip radiation surface 1 gb
As shown in the figure, the irradiation area S3 from the direction becomes a direction defined by the degree of the curvature, and can be an oblique direction with respect to the axial front of the entire probe.

Therefore, by directing the distal end emitting surface to the treatment site, it is possible to prevent the irradiation of the region other than the site. Further, by adjusting the degree of curvature, similarly to the above-described light guide paths 1a and 1a 'in FIG. 3, the irradiation directions to the front and a certain degree to the rear can be covered in almost all directions. It can correspond to the treatment site of the orientation.

FIGS. 6A and 6B are enlarged views of the tip of another example of the probe used in the laser treatment apparatus of the present invention.

Each of the light guide paths constituting the probe tips is a combination of a hollow light guide path and a solid light guide path.

The light guide path 1h in FIG.
At the tip of hb, a solid light guide path 1hd is provided to be fitted into the silver mirror surface 1ha. This fitting reduces the diameter of the end of the hollow light guide 1hb to a certain extent, and the solid light guide 1hb
The fitting portions of these are also made to correspond to this, and they are pressed against each other so that no gap is formed between them, so that airtightness is maintained.

The moving sleeve 1i provided at the tip end
Has the same configuration as the moving sleeve 1b of FIG. 3 and is composed of the same fixed part 1ia and moving part 1ib, and exerts the same effect. However, the fixed part 1ia has an air flow hole 1h.
c is provided so as to penetrate the hollow light guide path 1hb. The air circulation hole 1hc is provided for cooling the hollow light guide path 1hb.

Even with such a configuration, the light guide path 1 shown in FIGS.
a, 1a 'can exhibit the same effect.

The light guide path 1j in FIG. 6 (b) has a silver mirror surface 1ja at the tip of the hollow light guide path 1jb, as in FIG. 6 (a).
The solid light guide 1jd is provided so as to be fitted in the solid light guide. The shape of the solid light guide 1jd is curved similarly to the light guide 1g in FIG. 5, and the emission end face is also a straight end face. Further, an air circulation hole 1hc is also provided.

With such a configuration, the same effect as that of the light guide path 1g in FIG. 5 can be obtained. In addition, in the case of these light guide paths 1h and 1j, since the tip portion is solid, the autoclave resistance is significantly improved as compared with the case where the whole is hollow.

[0077]

According to the otolaryngological laser treatment apparatus of the present invention, a laser beam having a wavelength having a good energy absorption rate to water or a hydroxyl group is converted to a low energy density based on the knowledge on the onset mechanism of hay fever. It does not cauterize the tissue but heat denatures and coagulates the mucosal tissue that emits exudate.As a basic effect, it can treat the ears, nose and throat without giving the patient pain. And

In particular, according to the laser treatment device for otolaryngology according to the first aspect, a treatment device that embodies the above-described basic effects is specifically defined, without causing pain to the patient. It can treat hay fever and other ear, nose and throat disorders. The tip shape of the probe is
The laser beam is radiated from the probe not only to the front but also to the sides, so that the treatment site can be treated without using an endoscope. Laser light can be applied all over the nasal mucosa, etc., for treatment.

Further, since the energy density is low and the pulse is properly adjusted, the degree of pain to the patient can be further suppressed, and anesthesia for treatment is not required.

According to the laser treatment apparatus for otolaryngology according to the second aspect, in addition to the effect of the first aspect, the irradiation range of the laser beam in the outer circumferential direction is regulated as necessary by the moving sleeve. Therefore, when bleeding occurs locally, it is possible to prevent the irradiation of a portion other than the bleeding.

According to the laser treatment apparatus for otorhinolaryngology according to the third aspect, the tip of the light guide path of the probe is not a conical shape as in the first aspect, but a cylindrical shape.

Can be directed to the treatment site, so that irradiation is not performed at other sites.

According to the laser treatment apparatus for otolaryngology of the fourth aspect, in addition to the effect of any one of the first to third aspects, the configuration of the probe is defined, and this is a solid light guide path. Therefore, unlike a hollow light guide tube, autoclave can be performed without causing a problem of peeling of the inner surface of the silver mirror surface by the autoclave. Further, since the solid light guide is combined with the tip of the hollow light guide, the autoclave resistance is improved as compared with the case where the whole is made hollow.
