Description
Technical field
This utility model belongs to technical field of medical instruments.
Background technology
Beam-defining clipper is parts of X-ray machine, its basic structure is made up of the parts such as the incident lead window mouth of X-ray, the horizontal plumbous door of scalable, scalable longitudinal plumbous door, lamp, plane mirror, cross location-plate, fixed frame and outer housing, it is characterized in that: lamp center and x-ray focus are about plane mirror symmetry, from the light of lamp after flat mirror reflects, after passing perpendicularly through horizontal plumbous door, longitudinally plumbous door and cross location-plate, panadaptor forms rectangular light wild consistent with the wild size of X-radiation and center.
The requirement to the wild indicator of light is had in GB GB9706.12, the instruction of 29.202.7 to the wild indicator of light requires: using the focus of defined to panadaptor maximum distance apart perpendicular in the plane of reference axis apart from focus 1 m place or normal, the wild indicator of light must provide the edge of X ray, and must provide the average illumination being not less than 100 Ix; To the required precision of light wild indicator instruction in 29.202.9: in the wild plane of light, measure along the wild each main shaft of X ray, the deviation sum between the wild each limit of X ray to the wild corresponding each limit of light should not exceed the wild plane of light to 2% of focal length.
Above technical characteristic and GB, to the requirement of light source be: illuminance is large, the little preferably point source of volume.
At present, on market, beam-defining clipper all uses halogen tungsten lamp as light source, its shortcoming has be light effective rate of utilization low at two: one, reason is light source luminescent filament length and volume range is large, crevice projection angle is large and loose, the effect that the effect shone on plane mirror is similar to point source is thrown for making light source, a very little window must be opened on framework, allow light source by investing plane mirror again after this window, two are that halogen tungsten lamp light conversion efficiency is low and quite a few electric energy is converted to heat energy, due in these two reasons and GB to the requirement of the wild brightness of light, require that lamp rated power is larger, although current each producer uses the halogen tungsten lamp of different brands, but lamp power is 100W even 150W.Moreover, use halogen tungsten lamp to cause temperature near lamp high and bright, for preventing from scorching electric elements and wire near light source and preventing light leak to beam-defining clipper outside, a heat radiation hood for protecting rider must be installed additional; And staff is when adjusting light and being wild consistent with center with radiation field size size, need manually to adjust lamp position when turning on light and do not fill heat radiation hood for protecting rider, dazzling light and red-hot temperature make debugging efforts add difficulty.
Along with the development of science and technology, a kind of volume is little of point source, light source irradiation angle is little, High Efficiency Luminescence, energy-conservation, the large-power LED light bead that the power of same brightness is approximately 1/10th of the halogen tungsten lamp power that traditional beam-defining clipper uses obtains using more and more widely in each field of society, a lot of people uses large-power LED light bead to replace halogen tungsten lamp in trial, but beam-defining clipper uses large-power LED light bead to there is following point: 1. single limited brightness, the focus of defined is being used to panadaptor maximum distance apart perpendicular in the plane of reference axis apart from focus 1 m place or normal after being loaded on beam-defining clipper, the average illumination being not less than 100 Ix can not be provided, 2. power is twice, and illuminance is increased less than 1 times, but price wants high several times, and needs to increase radiator structure, 3. lamp pearly-lustre source is originally as rectangle, although volume is very little, in light open country, still have four seamed edge shadows of rectangle to exist, these problems have limited to the progress that large-power LED light bead uses on beam-defining clipper.
Summary of the invention
Goal of the invention of the present utility model is: for overcoming above-mentioned Problems existing, design a kind of beam-defining clipper using large-power LED light bead to be light source: use convex lens to increase illuminance, using LED rotational structure to make LED lamp bead rectangle seamed edge and rectangular light open country, seamed edge is parallel respectively ensures in rectangular light open country without four of LED seamed edge shadows.
This utility model solves the technical scheme that its technical problem adopts: its structure is by containing large-power LED light bead, the integrated lamp cap of drive circuit and lamp socket, convex lens, lamp holder adapter sleeve, rotate adjustment block, longitudinally adjust plate, laterally adjust plate, outer housing, fixed frame, the incident lead window mouth of X-ray, plane mirror, scalable is plumbous door longitudinally, scalable is plumbous door laterally, the parts compositions such as cross location-plate, it is characterized in that: integrated lamp cap is fixed in lamp holder adapter sleeve, convex lens is installed on lamp holder adapter sleeve and rotates between adjustment block, rotate in adjustment block and have circular arc direction mounting hole, can be fixedly connected with longitudinal adjustment after plate rotates 0 ~ 50 °, longitudinally adjustment plate has vertical direction mounting hole, be fixedly connected with after can adjusting up and down laterally adjusting plate, laterally adjustment plate there is the waist hole of horizontal direction, can be fixedly connected with after the adjustment of left and right on fixed frame, LED center O
1with x-ray focus O
2symmetrical about plane mirror, the light that LED sends is after convex lens convergence, flat mirror reflects, after scalable longitudinally plumbous door, the horizontal plumbous door of scalable and cross location-plate, panadaptor is formed rectangular light open country, make LED lamp bead rectangle seamed edge and rectangular light by rotating wild seamed edge be parallel respectively ensures without four of LED seamed edge shadows in rectangular light open country, by longitudinally and laterally adjustment ensures arbitrary focus screen distance on X-ray machine time the light open country of investing on panadaptor consistent with X-radiation open country size and center.
The beneficial effects of the utility model are: 1) use large-power LED light bead, because light source volume is little, make light uniformity in beam-defining clipper light open country good; 2) large-power LED light bead is used, own projection angle little (being generally 90 °-120 °), after using convex lens, projection angle is less, and after using convex lens, illumination increases 70-100%, light effective rate of utilization is high, thus can select that power is relatively little, the large-power LED light bead of advantage of lower cost; 3) use the rotation adjustment block that can rotate 0 ~ 50 ° that the wild seamed edge of large-power LED light bead rectangle seamed edge and rectangular light can be made parallel respectively, thus without four of LED seamed edge shadows in light open country; 4) do not need to install heat radiation shade and LED position rotates, longitudinal direction and laterally adjustment is separate, structure is simple, and operation adjustment is convenient.
