Abstract
A kind of shadowless operating lamp for used for medical procedures is installed in the bulb top parabolic reflector that Open Side Down, one by lampshade, light source bulb, one and places its upper end open of the hollow of parabolic reflector below to form around convex lens and one group of its reflecting mirror on every side that also places accordingly that equates with the positive multiple prismoid shape speculum number under the positive multiple prismoid shape speculum of light source bulb lower portion and the bulb.Promoting that shadowless operating lamp moves up and down is the size of the surgical field of view scope that illuminates of scalable.
Description
The present invention relates to a kind of shadowless operating lamp for used for medical procedures.
Existing shadowless operating lamp is made up of lampshade, four or nine even more a plurality of light source bulb and parabolic reflector, and this class shadowless operating lamp is because of a plurality of light sources of needs, so power consumption is big, complex structure, heaviness and cost height.
The purpose of this invention is to provide a kind of shadowless operating lamp simple in structure, a light source of needs, it is actually a kind of improved form that application number that I submit to " Patent Office of the People's Republic of China " on May 20th, 1 is " lamp for operation shadowless with single light source " utility application of 85201500, and its difference is the convex annular lens or the regular polygon convex lens group of the present invention's manufacture process more complicated of having replaced above-mentioned application with mirror structure.
This lamp for operation shadowless with single light source is made up of positive multiple prismoid shape speculum and one group of equal reflecting mirror of number thereof of lampshade, light source bulb, parabolic reflector, hollow.Light source bulb is installed in below the lampshade center, and light source is placed on the common focus of convex lens of light source bulb top parabolic reflector that Open Side Down and below, the positive multiple prismoid shape speculum upper end open of hollow is round the lower portion of light source bulb or in face of its bottom, about about 45 ° of its base angle, and be fixed on the lampshade by immobilising device with the convex lens of its below, the one group of reflecting mirror that equates with the positive multiple prismoid shape speculum number of hollow corresponding and be equally distributed on hollow positive multiple prismoid shape speculum on every side and be fixed on the lampshade wall.
Above-mentioned lamp for operation shadowless with single light source, the light that its light source shines downwards form a branch of parallel or intimate parallel light by the refraction of the convex lens under it and shine to the surgical field of view center.Also form the light of a branch of parallel downward irradiation by the parabolic reflector reflection of covering light source according to the light around reaching upward, it is through the reflection of the hollow positive multiple prismoid shape speculum of parabolic reflector below, it is equidirectional to the light that shines all around just to form some bundles and lampshade plane, invests surgical field of view through after the corresponding one group of mirror reflects that is fixed on the lampshade wall respectively again.So just reached the effect of general shadowless operating lamp.
Above-mentioned lamp for operation shadowless with single light source, its hollow positive multiple prismoid shape speculum can be replaced by a hollow garden platform shape reflecting mirror, and correspondingly the one group of reflecting mirror that equates with the positive multiple prismoid shape speculum number is replaced by an annular reflex mirror.
Above-mentioned lamp for operation shadowless with single light source, its hollow positive multiple prismoid shape speculum can be replaced by the bevel-shaped reflector of the non-positive multi-pyramid shape of a hollow, and the size of reflecting mirror group is also done corresponding change certainly.
Above-mentioned lamp for operation shadowless with single light source, its light source bulb and under convex lens can replace by the light source bulb of its diapire band convex lens.
Above-mentioned lamp for operation shadowless with single light source can and be fixed on floor stand, wall or the ceiling by the deformable flexibly metal hose connection of activity owing to lighter weight.Promote this shadowless operating lamp and move up and down, just can regulate the range size of the surgical field of view that illuminates.
Concrete structure of the present invention provides by following embodiment.
Fig. 1 is that analyse and observe and fundamental diagram at the center of shadowless operating lamp.
Fig. 2 is the upward view of shadowless operating lamp.
The positive eight pyramids-shaped mirror (3) of light source bulb (1) and parabolic reflector (2), hollow, convex lens (4) all are fixed on lampshade (5) by immobilising device and go up (not drawing in the concrete fixed structure chart).Light source bulb (1) is positioned on the common focus of parabolic reflector (2) and convex lens (4), the positive eight pyramids-shaped mirror of hollow (3) place parabolic reflector (2) under, its upper end open is around the lower portion of light source bulb (1), convex lens (4) is under light source bulb (1) and be fixed on positive eight pyramids-shaped mirror (3) inner face of hollow, and the reflecting mirror group (6) that eight reflecting mirrors are formed is corresponding with positive eight pyramids-shaped mirror (3) and be equally spaced and be fixed on lampshade (5) wall.The light that light source bulb (1) shines downwards shines to surgical field of view (7) by a branch of parallel light of convex lens (4) refraction back formation, form a branch of parallel light of irradiation downwards according to the light around reaching upward through parabolic reflector (2) reflection back, be divided into the parallel light of eight bundles respectively according to eight reflecting mirror groups (6) after passing through positive eight pyramids-shaped mirror (3) reflection again, form the parallel light of eight bundles through reflecting mirror group (6) reflection back and shine to surgical field of view (7) to correspondence.Whole shadowless operating lamp connects with deformable metal hose (8) and is fixed on floor stand, wall or the ceiling by the immobilising device (9) of being with screw hole.
Shadowless operating lamp lampshade of the present invention can be made with a thin metal or plastic plate. Convex lens useable glass or transparent plastic manufacturing. Speculum can directly be plated on metal or the plastics with the high metal of reflectivity and make.
