Abstract

The utility model discloses a laser irradiation head is used in treatment, include the shell and fix the optic fibre on this shell the storage tank has been seted up to the bottom surface of shell, at the built -in optical glass that is equipped with of this storage tank, the lateral wall of this optical glass with the exit end contact of optic fibre the even packing has the scattering particle in the optical glass be provided with the reflector layer between the inner wall of optical glass and shell. It is showing the effect: positive jetting out with the light deflection 90 that the fibre output face was jeted into, is followed to the principle of application scattering of light, total reflection to play the effect of shaking even light, even solely effectual, to long -time radiation treatment, can be fine avoid is burnt, simultaneously at the treatment in -process, light on the reflector layer during reflection loss little, the utilization efficiency of setting a camera is higher.

Description

Treatment laser irradiating head

Technical field

This utility model relates to laser therapy utensil technical field, specifically, is that one is treated and used laser irradiating head.

Background technology

Laser is one of 20th century mankind's greatness invention, and is widely used in a lot of field. The clinical value of low-intensity laser irradiation treatment is affirmed both at home and abroad, is mainly used in treatment inflammation and the multiple disease such as wound healing of pain, promotion traumatised tissue. Finding according to laser medicine, low level laser, at inflammation, wound healing, all has good curative effect, and the multiple disease aspects such as antiinflammatory, analgesia, promotion wound healing are had certain therapeutical effect.

But, treatment laser irradiating head of the prior art be usually present higher-energy laser optical fiber output face to therapentic part be 90 �� vertical, therefore in use optical fiber easily snaps off and causes a hidden trouble, and coplanar laser illumination is Gauss distribution, thus shadow surface optical power distribution is uneven, there will be the phenomenon of skin ambustion when long-time irradiation; When additionally in the process of whole treatment, light reflects on interface, loss is higher, and light utilizes less.

Summary of the invention

For the deficiencies in the prior art, the purpose of this utility model is to provide one and treats use laser irradiating head, and this irradiation head can realize and irradiate bright finish is 90 �� of inputs, and even light effect is good, the utilization ratio of light is higher, and result of use is good.

For reaching above-mentioned purpose, the technical solution adopted in the utility model is as follows:

One is treated with laser irradiating head, including shell and be fixed on the optical fiber on this shell, it it is critical only that: offers storage tank in the bottom surface of described shell, it is equiped with optical glass in this storage tank, the sidewall of this optical glass contacts with the exit end of described optical fiber, in described optical glass, uniform filling has microscopic scatterers, is provided with reflector layer between described optical glass and the inwall of shell.

Optical fiber is exported the laser of (point source) by this programme, imports from transparent tree optical glass side, and it is launched diffusion by the microscopic scatterers in optical glass, finally penetrates from the work surface of plate face this laser irradiating head i.e. vertical with light source incidence face. Optical glass uses the principle that light is totally reflected on the scattering of the microscopic scatterers within transparent resin sheet, transparent resin sheet interface, the light injected in fiber-optic output face deflects 90 ��, penetrate from front, thus playing the effect shaking even light, even light effect is good, for long-time irradiation treatment, it is possible to well avoid burning;Over the course for the treatment of, when light reflects on reflector layer, loss is little, and the utilization ratio of light is higher simultaneously.

Further, described microscopic scatterers distribution in array in described optical glass.

It is distributed by array, it is ensured that microscopic scatterers is for the dispersion effect of incident laser, thus ensure that the even light effect of this device.

Further, institute's optical glass is microarray resin sheet for optical, and material is PMMA, the diameter of described microscopic scatterers 5��30 nanometers.

Further, described reflector layer is optics aluminium coated, and this reflector layer is concave plane.

By said structure, not only ensure that less light loss, and diffuse-reflectance can be passed through, further ensure even light effect.

Further, being connected to handle on the side of described shell, described optical fiber is arranged in this handle. By above-mentioned handle, it is simple to be operated when treatment, improve the result of use of this device.

Further, being connected to limited step at the top of described storage tank, the bottom of this limited step contacts with the top of described optical glass.

Pass through said structure, it is possible to effectively optical glass is realized spacing, it is ensured that its stability over the course for the treatment of.

Further, described shell adopts medical ABS plastic or metal material to make.

Of the present utility model it has the advantages that: use the principle that light is totally reflected on the scattering of the microscopic scatterers within optical glass, optical glass interface, the light injected in fiber-optic output face deflects 90 ��, penetrate from front, thus playing the effect shaking even light, even light effect is good, for long-time irradiation treatment, it is possible to well avoid burning; Over the course for the treatment of, when light reflects on reflector layer, loss is little, and the utilization ratio of light is higher simultaneously.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model and operation principle are described in further detail.

As shown in FIG. 1 to 3, one is treated with laser irradiating head, including a discoid shell 1 and be fixed on the optical fiber 2 on this shell 1, the side of described shell 1 is connected to handle 7, described optical fiber 2 is arranged in this handle 7, storage tank 3 is offered in the bottom surface of described shell 1, it is equiped with optical glass 4 in this storage tank 3, the sidewall of this optical glass 4 contacts with the exit end of described optical fiber 2, in described optical glass 4, uniform filling has microscopic scatterers 5, is provided with reflector layer 6 between described optical glass 4 and the inwall of shell 1.

In the present embodiment, in order to ensure the even light effect reached after light scattering, described microscopic scatterers 5 is the distribution in array in described optical glass 4.

In this example, it is preferable that described optical glass 4 is microarray resin sheet for optical, and material is PMMA, the diameter of described microscopic scatterers 5 5��30 nanometers.

In this example, so that light can have good utilization rate, and ensure even light effect, it is preferable that described reflector layer 6 is optics aluminium coated, and this reflector layer 6 is concave plane.

As it is shown on figure 3, be connected to limited step 8 at the top of described storage tank 3, the bottom of this limited step 8 contacts with the top of described optical glass 4.

In this example, it is preferable that described shell 1 adopts medical ADS plastics to make.

Owing to the refractive index of optical glass 4 is more than air, after laser beam enters optical glass 4, after microscopic scatterers 5 scattering, angle of light �� changes, incidence angle �� overflows interface less than the certain angle time, incidence angle �� will be totally reflected more than the certain angle time on the interface of optical glass 4, continues concussion, scattering in optical glass 4, and finally overflows the interface of optical glass 4;

Overflow the light reflection through reflector layer 6 of aluminizing of optical glass 4 bottom surface, go successively to and in optical glass 4, repeat above procedure, reach to change into point source light beam the purpose of uniform area source;

Interface total reflection, medium inscattering, make light overflow after necessarily concussion therein, reached even light effect; Whole process light is only dependent upon the medium absorption to light in the loss of media interior, and does not have loss (about 10%) during reflection on interface, and light utilizes higher.
