Abstract
This utility model is in the art of medical apparatus. It relates to one integrated measuring tool that contains one improved miniature model. In this utility model, the improved miniature model is installed on a generic rotary base that is installed onto the bottom plate via the vertical plates on both sides. All the foregoing components have a central marking line thereon and are combined together to become a measuring tool of the scatterings at the head of medical linear accelerator. Test use shows that this tool has very good measuring effects and the position of the miniature model is not affected by the lead wires of the detector. Within the 180-degree rotational scope of the medical accelerator frame, the major axis of the miniature model can conveniently overlap with the ray axis at any angle. Miniature models of different specifications can be conveniently replaced. The whole model can be positioned in a convenient way, thus fundamentally overcoming the defects of prior models.
Description
Technical field
The utility model belongs to medical instruments field, is specifically related to a kind of instrument of measuring the scattering of clinac head
Background technology
Since European tumour and the scattering of the mini model measurement clinac head of radiation therapy association proposition use, the radiation therapy subject of mini model is used very extensive.A lot of scholars have done a large amount of research to the material of mini model, thickness, height etc.At present, various mini models have abroad appearred.According to the use principle of mini model, when mini model used, its long axis direction must overlap with the beam axis of medical accelerator.The ubiquitous major defect of existing mini model just is to use inconvenience.Mainly show, one, when detector places model, the extension line of detector makes mini model bottom uneven, is difficult for putting steady; Two, mini model does not have label, and long axis direction is difficult for vertical with beam axis when putting; Three, because existing mini model almost can not horizontal positioned, thereby can only prolong detection range, limit the expanded scope of detection range in vertical direction; When four, using the mini model of different size simultaneously, need place model repeatedly, time-consuming, effort.So far, the domestic also independently not mini model product of China comes out.
Summary of the invention
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of integration survey instrument that improves mini model that comprises is provided.Be specifically related to a kind of clinac head scatterometry tool.
Use the utility model, can make the placement of mini model not be subjected to the influence of detector extension line; In the medical accelerator frame 180 degree rotating ranges, the major axis of mini model can overlap with arbitrarily angled beam axis is convenient; It is convenient that the mini model of different size is changed; Whole model measurement is put simply; Fundamentally overcome the defective of existing mini model.
The utility model is that the technical scheme that its technical matters of solution is adopted is: improved mini model 1 is installed on the rotatable general base 2, and general base is installed on the horizonal base plate 4 by the riser 3 of both sides.The bottom of described mini model is made into the thin type common size, and retaining thread hole 6 or draw-in groove are arranged on the chassis, and the chassis of the mini model of different size is identical, is provided with centre mark line 5a at the top of mini model; Described rotatable general base central authorities are the mount pad 2a that can place mini model chassis, the both sides of mount pad have threaded hole 6 coaxial with the threaded hole on the mini model chassis, has centre mark line 5b on the mount pad equally, there are screw thread and rod shaped structure in the two ends of rotatable general base, rod shaped structure is as rotating shaft 8, and screw thread is used for the fixing whole rotating base of attaching nut after whole base rotates to desired location; The rotating base both sides also have backup plate structure 7, are used for stablizing the installed surface of base plate and vertical plates on both sides, guarantee the mechanical precision of solid tool, are useful on the mark line of the indication anglec of rotation on the backup plate; Described riser also has the center rotating hole 9 that is used for the mounting seat turning axle except anglec of rotation scale mark 10 and centre mark line 5c are arranged; Three horizontal adjustment screws are housed on the described horizonal base plate, are provided with the centre mark line equally.
The utility model has manifested it and has good effect through on probation: the mini model of different size is installed on the rotatable base by the chassis, firmly connects by the screw in the threaded hole, and the replacing of mini model is significantly convenient; Rotating base is installed on the riser, and the leaving water flat underside has certain distance, can satisfy existing needs with the range detector extension line; During use, wild cross curve of the light of clinac or locating laser line, when mark line overlapped on mark line on the mini model, mark line on the rotating base and the horizonal base plate, the major axis of mini model was just and the coincidence of accelerator beam axis; The rotating shaft of rotating base is installed in the rotating hole of riser, mini model and base can relative riser and horizonal base plate rotations, the frame of clinac can realize that in 270-360-90 degree scope the major axis of mini model and accelerator beam axis overlap, and can horizontal direction prolong measuring distance.

Embodiment
In the embodiment shown in fig. 1, whole survey instrument is made by organic glass.The general base 2 of whole rotation is processed by a blank.All parts all are provided with the centre mark line.Mini model 1 has the evagination chassis, and the symmetrical center excessively of chassis side is provided with runs through threaded hole.Rotating general base 2 central authorities is general bases, and base indent, the indent degree of depth are the mini model 1 chassis degree of depth, and position, size that the side symmetry runs through threaded hole are consistent with mini model 1 chassis threaded hole.Mini model 1 is installed on the general base 2 of rotation, fixes by screw.Rotate general base 2 and be retaining thread, turning axle, backup plate, connecting link successively in the lateral.Riser 3 is corresponding to the position indent of general base 2 backup plates of rotation, and there is rotating hole in indent central authorities, and per 5 degree have the angle index line around the female parts.The indent of rotating the backup plate of general base 2 and riser 3 is closely connected airtight and is touched, and turning axle is arranged in the rotating hole of riser 3.Rotate the screw thread that general base 2 stretches out the riser outside and fix with respective nut, when mini model 1 was in non-perpendicular measuring position, hold-down nut can guarantee in the measuring process that mini model angle can not take place changes.The rotating hole center of riser 3 to horizonal base plate apart from 15cm, eliminate the influence that the detector lead-in wire is placed whole survey instrument.
