Abstract
The present invention discloses a plate-type collimating device for radiotherapy equipment. The collimating device is in a convex flat plate type. On the same straight line positioned on the upper side of the small end of the collimating device, twenty-two focusing type collimating apertures are arranged on the basis of a central line, are uniformly distributed towards both sides, face the lower side of the large end and focuses on one point to be distributed in a fan shape. Both sides of the large end face of the collimating device are respectively provided with a positioning hole. Bottom parts on both sides of the large end face of the collimating device are respectively provided with a rectangular groove perpendicular to the large end face, and square through holes perpendicular to the large end face are arranged in the grooves. The included angles of the central lines of the twenty-two focusing type collimating apertures are 50 degrees. The collimating device has less thickness and low height, so the collimating device has small volume and light weight. The present invention adopts the material of integral tungsten 95 to process the focusing type collimating apertures with the proper aperture type and length and to ensure the consistency of the focus point. Both ends of the collimating device are provided with square holes for inserting a claw hook and a plane for being clamped by safety lock bolts; thus, the collimating device can be conveniently put on a radiation device of radiotherapy equipment to conduct the quickly automatic exchange with the used collimating device, and is additionally arranged in a collimating device storehouse.
Description
Technical field
The present invention relates to a kind of radiation appliance, relate in particular to a kind of board-like collimating apparatus of radiotherapy apparatus.
Background technology
The collimating apparatus that existing gamma knife is used is semisphere, barrel-shaped, piece shape structure, the big Heavy Weight of volume.Can not append the collimating apparatus kind after the collimating apparatus kind is dispatched from the factory less, this requirement that will satisfy conformal therapy has certain difficulty.
Summary of the invention
The object of the present invention is to provide a kind of board-like collimating apparatus of radiotherapy apparatus, carry out automatic quick exchange with the collimating apparatus of using on the radiation appliance with the radiotherapy apparatus that adapts to the applicant development and in the collimating apparatus storehouse, append.
In order to achieve the above object, the technical solution used in the present invention is: collimating apparatus is the convex plate armature, on the same straight line on the collimating apparatus small end, have with the center line be benchmark to both sides uniform, below big end, focus on 22 focusing collimating apertures that any is fan-shaped distribution, have pilot hole in collimating apparatus large end face both sides, have the rectangular groove vertical at collimating apparatus large end face two side bottoms, have the square through hole vertical in the rectangular groove with large end face with large end face.
Two collimating aperture center line angles of the outermost side of described 22 focusing collimating apertures are 50 °.Have central keyway on the collimating apparatus large end face.
The useful effect that the present invention has is:
1. collimating apparatus of the present invention is a plate armature, thickness and highly all very little, make the volume of collimating apparatus little, in light weight, and adopt whole tungsten 95 materials processings to go out the aperture of requirement and the focusing collimating aperture of conical pass and length, and guarantee the consistance of focus point;
2. collimating apparatus adopts central keyway centering, and two side planes paste the method for firm baseline trough and pack into; Upper-lower position is fixed on two shoulder planes, and under the effect on powerful extension spring and cross bar and push rod inclined-plane, board-like collimating apparatus obtains accurate resetting;
3. there are the square hole of confession grapple insertion and the plane that safe dead bolt blocks in board-like collimating apparatus two ends, and can realize quick replacing easily, and help appending.
Description of drawings
Fig. 1 is a structural principle synoptic diagram of the present invention;
Fig. 2 is the A-A cut-open view of Fig. 1;
Fig. 3 is that the K of Fig. 1 is to view;
Fig. 4 is pack into a synoptic diagram behind the gamma ray radiator of the present invention.
Among the figure: 1, collimating apparatus, 2, focusing collimating aperture, 3, central keyway, 4, pilot hole, 5, rectangular groove, 6, square through hole, 7 powerful extension springs, 8, shift fork, 9, rotating shaft, 10, push rod, 11, safe dead bolt, 12, the external shield piece, 13 baseline troughs.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, collimating apparatus 1 of the present invention is the convex plate armature, on the same straight line on collimating apparatus 1 small end, have with the center line be benchmark to both sides uniform, below big end, focus on 22 focusing collimating aperture 2 their single line spread that any is fan-shaped distribution, have pilot hole 4 in collimating apparatus 1 large end face both sides, have the rectangular groove 5 vertical at collimating apparatus 1 large end face two side bottoms, have the square through hole vertical 6 in the rectangular groove 5 with large end face with large end face.
Two collimating aperture center line angles of the outermost side of described 22 focusing collimating apertures 2 are 50 °.Have central keyway 3 on collimating apparatus 1 large end face.
As shown in Figure 4, when collimating apparatus 1 need be packed the baseline trough 13 of external shield piece 12 into, central keyway 3 centerings, two side planes paste the jail, because the inclined-plane on safe dead bolt 11 tops and the inclined-plane on push rod 10 tops, collimating apparatus rushes open safe dead bolt 11 and push rod 10 by gravity and inserts.Have pilot hole 4 in collimating apparatus 1 large end face both sides, under the effect of powerful extension spring 7 and Bars bar, push rod 10 inserts the pilot hole 4 of collimating apparatus 1, finishes accurate location.
Have the rectangular groove 5 vertical with large end face at collimating apparatus 1 large end face two side bottoms, collimating apparatus 1 is packed into behind the baseline trough 13 of external shield piece 12, and safe dead bolt 11 automatically resets, and inserts the rectangular groove 5 of collimating apparatus 1, pins collimating apparatus.
In the rectangular groove 5 of collimating apparatus 1, have the square through hole vertical 6 with large end face, in the time of need taking out collimating apparatus 1 from the baseline trough 13 of external shield piece 12, insert with the specific purpose tool driving lever in the breach E of shift fork 8, make shift fork 8 around rotating shaft 9 outside extension springs 7, thereby outwards pull out push rod 10; Simultaneously, the inclined-plane of safe dead bolt 11 also outwards leaves the rectangular groove 5 of pinning owing to the insertion of specific purpose tool; Grapple inserts two square through holes 6, the collimating apparatus proposition that can make progress easily.
