Description
Technical field
This utility model relates to the X-ray production apparatus parts, specifically be a kind of simple in structure, use cost is low and improve twi-tier blade driving device to the X-ray production apparatus beam-defining clipper of unnecessary X ray shielding.
Background technology
In the X-ray production apparatus system, its beam-defining clipper is installed in below the bulb usually, and bulb is launched X ray, and this X ray projects on the shot subject by the blade openings of beam-defining clipper inside.The size of the blade openings of beam-defining clipper, i.e. the size opened of blade determined the projection scope of the X ray of outgoing, and the scope redundance ray that exceeds blade openings that bulb is launched will be absorbed, stop and can not penetrate by blade.X ray is deleterious to the person, needs the projection scope of control X ray to make it shine the position that patient need check, the position that can protect patient not need to check like this is subjected to the irradiation of unnecessary X ray.
For avoiding of the injury of unnecessary X ray, need beam-defining clipper to shield unnecessary X ray to human body; The device that is used to control beam-defining clipper blade openings size is commonly referred to blade driving apparatus.The beam-defining clipper blade driving apparatus has gear fork driving device, steel wire rope fork driving device and leading screw to add line slideway driving device etc. at present.
The operation principle that drives the device of beam-defining clipper blade with the gear fork is: the rotation of beam-defining clipper panel upper knob is delivered on the gear of the identical number of teeth of pair of meshing by drive mechanism and driven gear rotates, thereby the rotation that makes this a pair of gear produce mutual reverse symmetry, this adverse movement drives a pair of fork motion that is fixed on this a pair of gear, and then make the blade that is fixed on the fork produce the symmetric motion that opens or closes, make blade open fully or close fully, also can rest on the centre that needs arbitrarily angled on.Yet, in this driving device, front and back blade and left and right sides blade need two groups of gears independently to control respectively, beam-defining clipper opening drive apparatus of announcing as Chinese patent and beam-defining clipper and the x-ray system with it, its patent No. is 200910141786.8, is exactly this situation.
Adding the operation principle that line slideway drives the device of beam-defining clipper blade with leading screw is: motor is directly or by the gear driven leading screw, is rotational transform rectilinear motion, drive the slide block of line slideway again, the driven vane motion, make blade open fully or close fully, also can rest on the centre that needs arbitrarily angled on.Yet, in this driving device, front and back blade and left and right sides blade need respectively two covers totally four cocainine thick sticks add line slideway and control.
The operation principle that drives the device of beam-defining clipper blade with the steel wire rope fork is: the rotation of beam-defining clipper substrate upper knob is transformed into rectilinear motion by steel wire rope, be delivered to driving wheel through one group of guide roller and make its rotation, and the fork that drive is fixed on the driving wheel rotates, thereby drive the blade movement that is fixed on the fork, make blade open fully or close fully, also can rest on the centre that needs arbitrarily angled on.Yet in this driving device, front and back blade and left and right sides blade need two groups of steel wire ropes independently to control respectively.
These beam-defining clipper blade driving apparatus of above-mentioned introduction, structure is more complicated all, and part is many, and cost is than higher.In gear fork driving device, the Gear Processing more complicated; When knob all was arranged on the front panel, left and right sides vane drive also needed the tumbler gear conversion; Can influence the precision of blade movement the intermittence of gear, and relatively difficulty is adjusted in assembling.Add in the line slideway driving device at leading screw, the cost of leading screw and line slideway also is difficult to realize using the knob manual operation all than higher.In steel wire rope fork driving device, though the relatively good processing of part, but exist and the same problem of gear fork driving device, be exactly the aperture of blade movement correspondence and the angle of knob correspondence be non-linear relation, causing scale can only be non-linear drafting; Left and right sides blade because fork becomes the circular curve motion, between the upper and lower apart from bigger, can't be done good X ray shielding with the front and back blade simultaneously, even cause under the closed fully situation of blade, also exists bigger leakage x radiation x.
In sum, the beam-defining clipper blade driving apparatus of prior art shields unnecessary X ray, the position that patient is not needed to check still has injury, complex structure, be unfavorable for maintenance, the use cost height makes a lot of hospitals can't bear the expense of buying or keeping in repair above-mentioned X-ray production apparatus, all makes troubles for hospital and patient.
