Description
Technical field
The utility model relates to clinac and how wild grating, multi-leaf optical grating.
Prior art
In the radiotherapy field, the target that medical circle is pursued always is the injury that reduces to greatest extent normal structure, strengthens the dosage of focus target area as much as possible.For realizing this target, the present price section adopts the treatment of multi-angle conform irradiation more, the raising of this mode precision is divided into two aspects: be suitable shape on the one hand, from the irradiation of ray incident direction restriction to focus periphery normal structure, method is to make the physics launched field of collimating apparatus consistent with the projecting section of focus in the ray incident direction.Plumbous mold, multi-leaf optical grating all can satisfy the technical requirement of this respect, and multi-leaf optical grating has higher suitable shape precision, but because drive system is too complicated, with high costs, the failure rate height has limited the penetration and promotion of this product; The conformal degree of plumbous mold is very high, makes simply, and cost is minimum, and to a lot of hospitals, this is a mature technology.Second aspect is the multi-angle irradiation, the advantage of doing like this is: guaranteeing that focus obtains under the prerequisite of sufficient dosage, can reduce the exposure dose of single angle, thereby alleviate injury to normal structure and sensitive organization, the launched field shape that this just requires illumination angle of every replacing all will change plumbous mold again or adjust multi-leaf optical grating, automatically multi-leaf optical grating can satisfy the requirement of this respect easily, existing how wild grating automatically can be changed plumbous mold automatically, but process complexity, poor reliability, cost are not low yet; When manually changing plumbous mold, require therapeutic process to suspend, doctor or physics teacher reenter therapeutic room and carry out associative operation, and every replacing once irradiating angle said process all will repeat once.Consequently increased treatment time greatly, patient understands fidgety, fatigue, and twisting causes treating precision and reduces greatly.
Summary of the invention
To be solved in the utility model is prior art process complexity when changing the collimating apparatus of different launched fields automatically, poor reliability, the technical matters that cost is high.
In order to solve above technical matters, the technical scheme that the utility model is taked is:
A kind of collimating apparatus gear train is characterized in that, it comprises the erecting frame of two cross slide waies that are parallel to each other, transversal driving mechanism, slide plate, two longitudinal rails that are parallel to each other, vertical driving mechanism and splendid attire collimating apparatuss.Described two cross slide way bottoms that are parallel to each other connect with the basis, and the top slide rail is connected with slide plate; Two longitudinal rail bottoms that are parallel to each other are connected with slide plate, and the top slide rail is connected with erecting frame; Described transversal driving mechanism is connected with slide plate with the basis, drives slide plate and moves along horizontal on two cross slide waies that are parallel to each other; Described vertical driving mechanism and slide plate and erecting frame connect, and the drive installation frame is along the longitudinal movement on two longitudinal rails that are parallel to each other.
Described horizontal and vertical driving mechanism comprises motor, motor fixing seat, shaft coupling, screw mandrel, bearing, screw rodb base, synchronous band, belt wheel, nut.Motor and screw mandrel link together by shaft coupling; Bearing and screw rodb base are supported on the screw mandrel two ends; Belt wheel is fixed on the afterbody of two screw mandrels, and two belt wheels link together by synchronous band, and the synchronized movement of motor is passed to the screw mandrel of opposite side; Nut cooperates with screw mandrel; The nut of transversal driving mechanism connects with basic fixed, and vertically the nut of driving mechanism is fixedly connected with erecting frame; Motor fixing seat is installed in motor on the slide plate.
After having adopted technique scheme, the casing that can hold a plurality of different collimating apparatuss during use simultaneously is placed on the erecting frame, utilize horizontal and vertical driving mechanism, move by the horizontal and vertical of erecting frame, can realize the automatic replacing of collimating apparatus, process complexity when having solved prior art replacing collimating apparatus, poor reliability, the technical matters that cost is high.
