Description
Technical field
The present invention relates to the medical radiotherapy instrument, relate in particular to a kind of device of medical radiotherapy instrument.
Background technology
The medical radiotherapy instrument generally comprises central processing control device, therapeutic bed, treatment main frame, power supply and device for signalling, electric cabinet control device etc.Wherein, the treatment main frame comprises rotating cylinder, the x light generating apparatus and the image collection receiving system that are used for spiral-fault scanning are housed on the rotating cylinder, and are used for radioactive source, grating and the collimator apparatus thereof that radiotherapy is used, and the dosage checkout gear etc. that is used to detect radiotherapeutic effect and radiotherapy progress.
Wherein, radioactive source device, grating and collimator apparatus thereof are a critical piece, and it is related to the radiotherapy system overall structure and arranges and radiocurable effect and efficient.
The radioactive source device of traditional spiral-fault radiation therapeutic system comprises a plurality of cobalts-60 radioactive source, with its coupling be many cover multi-leaf optical grating collimator apparatus.It realizes that the three-dimensional suitable shape and the strength regulated shape-adapted practice are, on some irradiation positions, forms by electric multiblade optical grating earlier and the suitable shape launched field of tumor shape basically identical according to the form of tumor, and then finish the intensity conform irradiation of tumor thickness direction with the difform open country of contracting, the overlapping step that forms dose intensity with repeatedly irradiation distributes final the realization and tumor form and all consistent three-dimensional therapeutic effect of dose distribution.
Yet electric multiblade optical grating is to be overlaped by many independently tungsten alloy thin slices and micromachine to constitute, and at first it will be subjected to the restriction of structure and size, and just accurately the shape with tumor is consistent in the visual field, and suitable shape open country is obviously very coarse; In addition, need flexible motion between thin slice, therefore, that also can not lean between the blade is too tight, and this just unavoidably can produce interlobate slit source ray, and this makes the performance of strength regulated shape-adapted launched field and quality have a greatly reduced quality; Its three, the tungsten alloy blade is by step motor drive, motion needs the time, image-guided strength regulated shape-adapted in, the mode of moving with regard to not adopting more advanced beam to follow the organ movement can only adopt therapeutic bed to follow technology, and the speed of following can be affected accordingly.
As mentioned above, adopt many radioactive sources, and adopt the multi-leaf optical grating collimator, it is low to make that radiotherapy system complex structure, its image are followed speed, makes therapeutic efficiency poor; And the radiotherapy safety is not high, and therapeutic effect is poor.
At the defective of above-mentioned multi-leaf optical grating and collimator apparatus thereof, a kind of novel medical grating and collimator apparatus thereof arise at the historic moment, and this kind grating is formed by the stack of the cellular needle chamber of multilamellar, offer abundant, enough thin vertebral foramen on this cellular needle chamber.The grating aligner of Pei Heing comprises multilamellar coaxial annular guide rail, grating filler automatic filling device, grating filler automatic unloader with it, rail-changer equipment and grating grass-hopper.Wherein, described a plurality of cellular needle chamber is installed on the respective layer of multilamellar coaxial annular guide rail separably, during the running of each layer of ring-shaped guide rail, its needle chamber that carries is transported to the position of grating filler automatic filling device and grating filler automatic unloader, grating filler automatic filling device, grating filler automatic unloader are controlled optionally with in implant (tungsten pin or the tungsten bar) honeycomb-type grating of packing into, or with implant (tungsten pin or tungsten bar) by releasing in the honeycomb-type grating.After operation is finished, superpose and form the grating corresponding with shone thing thereby each layer of ring-shaped guide rail is transported to ad-hoc location with needle chamber.Grating after the grating grass-hopper of grating aligner superposes the multilamellar needle chamber afterwards transfers between radioactive source and the shone thing.The beneficial effect of the collimator apparatus of this kind honeycomb-type grating is mainly reflected in: (1) this honeycomb-type grating adopts cellular and reaches the synergetic structure of multilamellar, thereby has accurate suitable shape and intensity adjustments function; (2) closely stack between the multilamellar needle chamber, do not exist the ray crack to leak, improved on every layer of needle chamber guide rail of collimator apparatus of safety (3) this kind honeycomb-type grating and can carry a plurality of needle chambers, many cover pin-packaging devices and needle backing device can be set, many cover rail-changer equipments, and cooperate grass-hopper efficiently, higher grating is regulated (the dress pin and the withdraw of the needle) efficient and higher grating switches (carrying out grating at treatment plan in real time switches) efficient thereby have, and has the speed of well following when image is followed the tracks of treatment.
Summary of the invention
The purpose of this invention is to provide a kind of automatic unloader of honeycomb grating filler, can be automatically with implant (tungsten pin or tungsten bar) by releasing in the honeycomb-type grating.
For achieving the above object, automatic unloader of honeycomb grating filler provided by the invention comprises: first cylinder that apparatus main body and the control device main body that is connected with apparatus main body seesaw, apparatus main body comprises bearing again, second cylinder, cylinder push-rod, protect and lead device, push pin and guard plate apparatus, wherein, second cylinder is fixed on the bearing, second cylinder connects cylinder push-rod, cylinder push-rod connects protects and lead device, protect and lead described pushing pin is set on the device, guard plate apparatus is fixed on the bearing, guard plate apparatus inside has host cavity, protect and lead device and described pushing pin is mounted slidably in host cavity, guard plate apparatus is provided with opening, pushes pin and can stretch out the outside by opening part.
As mentioned above, the present invention can be urged to assigned address with apparatus main body by first cylinder, by second cylinder and cylinder push-rod thereof, protect and lead device, structure such as push pin, can automatically finish the operation of unloading of honeycomb-type grating inner stuffing.
