なつた。[Technical background of the invention and its problems] Conventionally, the treatment of mother's spots has been performed by surgeons, dermatologists,
Various attempts have been made in several fields such as radiology. That is, in the surgical field, treatment methods using excision and suturing, skin grafting, epidermal abrasion, etc.
In dermatology, drug therapy, dry ice therapy, electrolysis, etc., and in radiology, radium therapy, cobalt therapy, strontium therapy, etc. can be mainly mentioned. However, none of these treatment methods can achieve sufficient therapeutic effects considering the degree of invasion to the patient. In addition, the treatment itself causes pain to the patient and may require hospitalization.
Moreover, they have drawbacks such as a long treatment period, and therefore there has been a strong desire to improve these treatment methods.

たものがレーザ治療装置である。 On the other hand, in recent years, histological research on nevi has progressed,
The clarification of the mother group is gradually being revealed. Pigmented abnormal cells, such as so-called red birthmarks, generally have lower brightness than normal cells, and absorb visible light more strongly than normal cells, which have higher brightness. Therefore, when these abnormal cells are irradiated with high-energy light in the visible light range, this light is selectively absorbed by the abnormal cells and converted into thermal energy. As a result, abnormal cells are strongly burned and destroyed. On the other hand, normal cells generally have high brightness and absorb less of the aforementioned high-energy light, so they are less damaged by heat. Therefore, if you irradiate an abnormal vascular nevus with the aforementioned high-energy light, the abnormal cells will be selectively burned and removed.
It will be extinguished. However, normal cells with relatively high brightness,
Sweat glands, skin, etc. absorb almost no light, so irreversible damage is avoided, and burns on normal cells, skin surfaces, etc. caused by light quickly heal with the formation of minute scars. As mentioned above, a certain wavelength in the visible light range is selected that absorbs less light energy for normal cells in the affected nevus, and increases the amount of light energy absorbed for colored cells. By setting the energy density of the wavelength to a predetermined value, colored cells can be selectively destroyed and eliminated. A typical example of light that meets such conditions is laser light, and a laser treatment device utilizes this laser light as a treatment means.

In the figure, the main body 1 of the apparatus is composed of a laser oscillator 1B, a power supply 1A, an operation panel 1C, and other parts necessary for laser oscillation. The laser light emitted from the oscillator 1B is

療を行つている。 Examples of lasers that have a relatively large output in the visible light range and are in practical use and are effective for treating colored nevi include argon lasers with a wavelength of 5140 Å, ruby lasers with a wavelength of 6943 Å, and the like. A ruby laser can obtain a large output and a large irradiation area, but has the drawback that the time interval between irradiations is long because it is pulsed light. On the other hand, the argon laser has the disadvantage that its output is relatively low at about several watts, but it has the characteristics of good controllability of the laser beam, small irradiation area, good operability of the handpiece, and easy handling. Therefore, it is suitable for treating areas that require delicate and delicate treatment. Generally, in such a laser treatment device, during treatment, the operator holds the handpiece 4 in his hand, and while checking the affected area with the naked eye, sequentially moves the laser beam irradiation position by the amount of laser beam irradiated from the tip of the handpiece 4. , and treatment is performed by intermittently irradiating laser light with a foot switch or the like.

As a result, the laser beam whose intensity distribution has been made uniform by the Kaleidoscope (trademark) 7 is transmitted through the end face 14 and irradiated onto the affected area. In addition, since the end surface 14 of the transparent plate-like body 13 is contaminated by tissue fragments, carbonized, cauterized pieces, etc. from the affected area of the living body during laser beam irradiation, the transparent plate-like body 13 is configured to be detachable manually from the transparent cylindrical body 12. , and are used while being replaced with new ones from time to time.

Also, a light guide path 32 for guiding the laser beam and electric contacts 22 and 24 for supplying power to the guide light source 30 are provided.

る。 When configured as described above, the laser oscillator 1
A laser beam having an intensity distribution unique to the laser beam oscillated from B is first focused by a condensing lens, and enters the incident end face of the light guide fiber 3 located near the focal point. The laser light incident on the light guide fiber 3 travels while repeating total reflection inside the fiber, and is emitted from the output end face of the light guide fiber 3. This emitted laser light is incident from one end of a Kaleidoscope (trademark) 7 having a transparent rectangular column shape. The laser light incident on this Kaleidoscope (trademark) is repeatedly totally reflected by the four walls as it travels through the interior, making the light intensity distribution uniform.
A rectangular laser beam is emitted from the other end of the laser beam. In this way, a uniform irradiation surface is formed on the affected area, and good treatment results without uneven burning can be obtained.

は石英で構成した場合、フレネス反射損失の値が
最も大きく、他の損失はほとんど無視できる。 However, the transparent rectangular columnar kaleidoscope (trademark) 7 is formed using an optical material such as optical glass, such as BK-7 (seven types of silica crown), and the light guide fiber is used to improve the operability of the device. is essential. In this way, two types of optical components are used: a flexible fiber that freely guides the laser light emitted from the laser oscillation unit, and a kaleidoscope (trademark) that uniformizes the laser light with the desired intensity distribution. Therefore, transmission loss occurs when laser light enters or exits these optical components. The main elements of this transmission loss include Fresnel reflection loss, impurity loss, scattering loss, etc., but as mentioned above, when the optical component is made of quartz, for example, Fresnel reflection loss has the largest value, and the other losses are almost negligible.
フレネル反射損失の理論値は、一般に次のよう
に表わすことができる。 The theoretical value of Fresnel reflection loss can generally be expressed as follows.
フレネル反射損失Ｒ
＝（n2−n1／n2＋n1）≒3.5％ ……(1)
n1：空気の屈折率＝1.0
n2：石英の屈折率＝1.46
従つて光学部品の一面当りの損失値は、その面
精度条件、光学的結合条件等によつて多少増加
し、一般に５％程度となり、装置全体の透過損失
がかなり大きくなるという欠点があつた。 Fresnel reflection loss R = (n 2 - n 1 / n 2 + n 1 )≒3.5% ...(1) n1: refractive index of air = 1.0 n2: refractive index of quartz = 1.46 Therefore, loss per surface of optical component The value increases somewhat depending on the surface precision conditions, optical coupling conditions, etc., and is generally about 5%, which has the disadvantage that the transmission loss of the entire device becomes considerably large.

図りにくい欠点もあつた。 Furthermore, there are a large number of mechanical parts to mechanically preserve the light guide fiber and Kaleidoscope (trademark) and to connect them with high positional accuracy, and the shape is complicated, making it difficult to reduce the weight of the handpiece in particular. There were also drawbacks.

The purpose of the present invention is to provide a laser treatment device with good operability.

07 is provided at the end of the light guide fiber 105. A protective cover 108 is detachably attached to the output end of the sleeve 107, and when the laser beam is irradiated to the affected area, the output of the light guide fiber 105 is caused by vaporized fine substances generated from the affected area. This prevents the end face 109 from becoming contaminated.

The laser beam oscillated from the optical fiber 01 is focused by a condensing lens 103 housed in a coupler 102 and enters the light guide fiber 105 from the incident end surface thereof. The laser light that has entered the light guide fiber 105 in this way is repeatedly totally reflected on the four walls like a so-called kaleidoscope (trademark) as it travels inside the light guide fiber 105.
The output end 10 of the light guide fiber 105 becomes a laser beam with a uniform energy distribution spread over the entire cross section of the
It is emitted from 9. Therefore, the emitted laser light passes through the protective cover 108 and is irradiated from the output surface 108A toward the affected area, so that a good treatment result without uneven burning can be obtained.

ーザ治療装置を提供することができる。[Effects of the Invention] As detailed above, according to the present invention, the core portion of the light guide fiber, which has the role of propagating laser light, has a polygonal columnar configuration, and each wall thereof is a total reflection surface. As a result, the light guiding fiber has both a light guiding function and a uniformizing function for the laser beam, and as a result, the number of incident surfaces and reflecting surfaces in the light guiding path can be halved compared to the conventional example, and the optical The transmission loss of the parts is halved, and a laser treatment device with high transmission efficiency can be obtained. In addition, the handpiece part has an integrated structure that combines the light guide function and the uniformity function, so it has an extremely simple structure, and it is lightweight, easy to assemble, and easy to operate, with few parts. Moreover, it is possible to provide a laser treatment device equipped with a fiberized Kaleidoscope (trademark) with high uniformity efficiency.
