Abstract
The photoconductive device that phototherapy is used comprises fiber light guide (1) and is contained in the astigmatic element (5) of fiber light guide (1) far-end.The containment vessel (4) of fiber light guide (1) is made and is stretched out outside the end face (6) that fiber light guide (1) is held far away, and end face (6) is formed a closed cavity therewith, all is full of with the optics turbid media (7) that is used as astigmatic element (5).
Description
The invention belongs to and transmit the photoconductive device that radiant energy is used, belong to the photoconductive device that phototherapy is used more precisely.
The present invention can be applied in medical field fruitfully, so that the pathology focus in implementing the inner chamber that can be difficult to arrive to patient's organ when inner chamber laser is lived the treatment disposal positions the light treatment.
Known optically-derived device used for optical therapeutics, it comprises fiber light guide and makes the astigmatic element of exposed photoconduction leaded light heart yearn form, handled (referring to " Optics and laser technology " with etching acid on its surface, 1984, February, H.Fujll and other, " Light Seattering Properties of a rough-ended Optical fibre, " pp.40-41).
The said equipment is easy to brittle failure in patient's organ and causes danger because its astigmatic element is frangible parts, disposes so can not be used for carrying out the inner chamber laser therapy.
Known phototherapy leaded light equipment; it comprises that optical fibers that has leaded light heart yearn and reflecting sheath and containment vessel and the astigmatic element that is contained in the fiber light guide far-end are (referring to " Lesers in surgery and medicine "; No.6; 1986; M.Arn-field and other; " Cylindrical Irradiator Fiber Tip for photodynamic therapy ", P.151).
In above-mentioned optically-derived device used for optical therapeutics, astigmatic element is done cup-shaped, and the naked section of the end face of its outer wall and fiberoptic leaded light heart yearn bonds together, and the inner surface of its outer wall then is coated with epoxy resin.
The said equipment also has traumatic danger, thereby can not guarantee the safety of patient when carrying out inner chamber laser therapy disposal.
The complex manufacturing technology of this equipment.This equipment can only provide a kind of radiant light distribution characteristics curve of form in addition, that is can not guarantee that the shape of its radiant light distribution characteristics curve can be complementary with the shape of focus, so just can not obtain best therapeutical effect.
The basis of task of the present invention is to found the photoconductive device that a kind of phototherapy is used; its fiberoptic containment vessel is all done to such an extent that can not make patient produce wound when the phototherapy with astigmatic element; but also can obtain the optimal treatment effect with combining of focus shape by the shape of radiant light distribution characteristics curve, the structure of its photoconductive device is also quite simple simultaneously.
This reaches in the following manner: in the optically-derived device used for optical therapeutics of fiber light guide that includes band leaded light heart yearn and reflecting sheath and containment vessel and the astigmatic element that is contained in this fiber light guide far-end; according to the present invention; fiberoptic containment vessel is made and is stretched out outside the end face of fiber light guide far-end; and end face constitutes the cavity of a sealing together therewith, and astigmatic element then is made of the photoconduction turbid media that contacts with fiberoptic end face and be filled in the formed whole enclosed cavity.
The version of this optically-derived device used for optical therapeutics can be got rid of patient fully in the possibility of carrying out taking place when the inner chamber laser therapy is disposed wound, i.e. the reliability of its use is very high, and uses simple structure just can obtain best therapeutic effect.
The present invention subsequently will be described in detail by following drawings and Examples, wherein
Fig. 1 represents the photoconductive device (longitudinal sectional view) that phototherapy of the present invention is used;
Fig. 2 is the radiant light distribution characteristics curve with spheroid and sphere-like by photoconductive device shown in Figure 1 obtained;
Fig. 3 is the radiant light distribution characteristics curve with garden anchor ring shape by photoconductive device shown in Figure 1 obtained.
Optically-derived device used for optical therapeutics of the present invention comprises the fiber light guide 1(Fig. 1 that has leaded light heart yearn 2 and reflecting sheath 3 and containment vessel 4) and the astigmatic element 5 that is contained in fiber light guide 1 far-end.
Containment vessel 4 stretches out outside the end face 6 of fiber light guide 1 far-end, and end face 6 forms a closed cavity together therewith.Astigmatism element 5 is manufactured by the medium 7 of optics muddiness, and it contacts with the end face 6 of fiber light guide 1 and is filled in the formed whole closed cavity.
Can utilize glue that epoxy resin, low-molecular-weight resin or polyamide make as the optics turbid media.
The operation principle of optically-derived device used for optical therapeutics of the present invention is as follows.Laser (not marking among the figure) is propagated and is entered in the astigmatic element 5 along the leaded light heart yearn 2 of fiber light guide 1, and in its optical opacity medium 7 scattering takes place.The laser emission of scattering is passed containment vessel 4 and the far-end of photoconduction ejaculation from equipment of the present invention.
According to laser in optical opacity medium 7 attenuation quotient and astigmatic element 5 along the length on fiber light guide 1 optical axis 8 directions, can obtain difform radiant light distribution characteristics curve.
Astigmatism element 5 is along the attenuation quotient ε of optics turbid media 7 in length Z on optical axis 8 directions of fiber light guide 1 and the associated above-mentioned astigmatic element 5, can guarantee is enough to carry out under the efficient laser metacheirisis situation at uniformity of radiation, can obtain various radiant light distribution characteristics curve.
When Z＜1/ (ε) or Z＞1/ (ε), radiant light distribution characteristics curve 9,10 and 11(Fig. 2) be spherical respectively and the ellipsoid shape.The characteristic curve of this form is widely used in the phototherapy of pulmonary abscess, pleura empyema, maxillary sinusitis, chronic gastric duodenal ulcer.
When Z=1/ (ε), radiant light distribution characteristics curve 12(Fig. 3) be the garden annular.The characteristic curve of this form is used to the location phototherapy of pathology focus on the wall of the lumen, for example chemical burn of esophagus, urethritis or general urethral disease.
Owing to might obtain radiant light distribution characteristics curve, just can guarantee best illumination and maximally utilise radiant light as the treatment factor to definite form.
Therefore, phototherapy light guide equipment of the present invention, can be used for that laser emission is acted directly on and be arranged in tube chamber minimum dimension that patient's organ is difficult to arrive is on 1.2～1.8 millimeters the pathology focus, for example acts on wound surface and postoperative suture, duct inflammation, pleura empyema and the pulmonary abscess of urethra.
In addition, the described optically-derived device used for optical therapeutics of the application is further characterized in that use is highly reliable and simple in structure.
