This invention provides a dual wavelength phototherapy device for cartilage repairing using nanogold mixed biological gel. The phototherapy device consists of one or two light sources, a power supply and a control panel. The output light of the said light source is delivered to the treated cornea via an optical set, optical fiber or a hand piece or an endoscope. The said device may also consist of an observing endoscope having an infrared fiber probe. The said light source can be a laser or a LED having a wavelength range of 750 to 980 nm or UV-blue at 350 to 460 nm. The said device provides quantitative, time controlled and adjustable speed for photo polymerization or gelling via the irradiation light power, period and modes. The power of the UV-blue or the infrared light t the treated area is 0.1 to 10 W depending on its spot size of 1.0 to 20 mm. The treating period range is 10 to 600 seconds.本創作係提供一種使用奈米金生物膠之雙波長軟骨修復光療儀。該軟骨光療儀包括:一個或兩個光源器,一電源器,一面板控制顯示。該光源器輸出光經由一光學鏡片組或光纖或手柄輸出。也可經由一傳輸內視鏡將能量傳輸到軟骨修復治療部位。該軟骨光療儀也可包括內有紅外線光纖探頭之觀察內視鏡。該光源器包括近紅外雷射或LED光源(波長750到980奈米),也可包括紫藍光源(波長350到460奈米)。本創作經由控制照射光功率,照射时间及其照射方式,达到定量定时及可调速度之光聚合或膠凝。該紫藍或红外輸出光在軟骨修復治療部位之功率範圍0.1瓦到10瓦,依治療部位直徑範圍(1.0到20毫米)而定。治療部位照射時間範圍10秒到600秒。(10)‧‧‧電源器(11,12)‧‧‧面板控制顯示(13)‧‧‧手動開關(14)‧‧‧腳踏開關(15)‧‧‧電源線(20)‧‧‧光源器(30)‧‧‧光學鏡片組(21)‧‧‧輸出光
