The present invention discloses a medical apparatus featuring adjustable illumination range, including a body, a light emitting module, an elastic element and a positioning element. The body has a hollow shape, one end of which has a tool head and is fitted with a lens. The other end has a rear opening. The rear opening communicates with the lens through a receiving space in the body. The body is provided with plural first helical grooves at a position corresponding to the rear opening. The light emitting module is movably positioned in the receiving space and has one end comprising a light guide element extending in a direction toward the lens, so that the light generated by the light emitting module is projected to the outside via the light guide element and the lens. The elastic element is so configured as to match with the receiving space, with its two ends abutting, respectively, an inner wall surface of the body and one end of the light emitting module. A plurality of first threads is formed on the positioning element, and the first threads can rotate along the first helical grooves, so that the positioning element can be mounted to the rear opening and abut the other end of the light emitting module. As a result, during the rotation of the first threads along the first helical grooves, the distance between the light guide element and the lens will be varied accordingly, thereby enabling light rays to pass through the lens at different refraction angles for the projection of different illumination ranges.本發明係一種能調整光照範圍之診療裝置,包括一本體、一發光模組、一彈性元件及一定位元件,該本體係呈中空狀,其一端設有一工具頭及嵌設有一透鏡,其另一端則設有一後開口,該後開口係透過本體內之容置空間連通至該透鏡,且該本體上對應於該後開口之位置設有複數道第一螺紋;該發光模組係活動地定位在該容置空間中,其一端朝該透鏡之方向延伸設有一導光元件,使該發光模組產生之光線經由該導光元件及透鏡,投射至外界;該彈性元件之構型係與該容置空間相匹配,其兩端分別抵靠至該本體之內壁面及該發光模組之一端;該定位元件上設有複數道第一螺牙,該等第一螺牙係能沿著該等第一螺紋旋轉,使該定位元件能定位至該後開口,且抵靠至該發光模組之另一端。如此,在該等第一螺牙沿著該等第一螺紋轉動的過程中,該導光元件及透鏡間之距離將隨之變化,令光線能以不同折射角度穿過該透鏡,進而投射出不同的光照範圍。2...診療裝置21...本體210...工具頭211...前開口211a...透鏡212...後開口212a...第一螺紋213...容置空間213a...位移槽213b..
