【摘要】：激光是受激輻射產(chǎn)生的。它具有亮度高，方向性強(qiáng)，相干性好，單色性好的特點(diǎn)。激光在醫(yī)學(xué)上的研究和使用已超過25年的歷史，特別是在眼科領(lǐng)域的應(yīng)用最為深入而廣泛。激光治療眼病有許多獨(dú)到之處：因?yàn)榧す庥泻芏辔锢硇孕?yīng)，，如壓強(qiáng)效應(yīng)，光熱效應(yīng)，電磁場效應(yīng)等。正因?yàn)樯啬ず鸵暰W(wǎng)膜有很多豐富的色素，容易吸收光能，轉(zhuǎn)化為熱能，從而使激光照射達(dá)到治療目的。目前眼科激光治療主要用于：凝固新生血管，封閉黃斑滲漏點(diǎn)，治療眼底��；封閉視網(wǎng)膜裂孔，治療視網(wǎng)膜脫離；準(zhǔn)分子激光治療屈光不正虹膜切除，治療繼發(fā)性青光眼等。 本設(shè)計(jì)重點(diǎn)是制作一個(gè)眼科激光治療儀，即卡爾.蔡司VISULAS Trion眼底激光器的反射裝置，使入射光通過45°的反射鍍膜，反射到盛放人眼細(xì)胞的培養(yǎng)皿上，從而模擬激光對人眼細(xì)胞的照射，達(dá)到臨床研究目的。通過測量從50mw-200mw的激光能量發(fā)射，每個(gè)能量值測量十組反射能量數(shù)據(jù)，取平均值，分別測量鍍鋁金屬高反射膜、鍍銀金屬高反射膜、多層介質(zhì)高反射膜等三種不同鍍膜對入射激光的反射率，對比鍍膜反射率，找出多層介質(zhì)高反射膜為最適合培養(yǎng)人眼細(xì)胞的反射鍍膜，從而完成激光反射裝置的制作，交付臨床研究使用。
[Abstract]:The laser is produced by stimulated radiation.It has the characteristics of high brightness, strong directionality, good coherence and good monochrome.Laser has been used in medicine for more than 25 years, especially in ophthalmology.Laser treatment of eye diseases has many unique features: laser has many physical effects, such as pressure effect, photothermal effect, electromagnetic effect and so on.Because the pigment film and retina have a lot of pigments, it is easy to absorb light energy and convert it into heat energy.At present, ophthalmic laser therapy is mainly used for coagulation of neovascularization, sealing of macular leakage, treatment of fundus disease, closure of retinal holes, treatment of retinal detachment, excimer laser treatment of ametropia iridectomy, treatment of secondary glaucoma, and so on.The focus of this design is to make an ophthalmic laser therapy instrument, I. E. Carl.The reflection device of Zeiss VISULAS Trion fundus laser makes the incident light pass through the 45 擄reflection coating and reflect on the petri dish containing the human eye cells, thus simulating the laser irradiation to the human eye cells and achieving the clinical research purpose.By measuring the laser energy emission from 50mw-200mw, ten groups of reflection energy data were measured for each energy value, and the average values were used to measure the aluminized metal high reflectance film and silver plated metal high reflection film, respectively.The reflectivity of three kinds of coatings, such as multilayer dielectric high reflection film, to incident laser, was compared, and the multilayer medium high reflection film was found to be the best reflection coating for cultured human eye cells, thus the laser reflectance device was made.Delivery of clinical research.
