Abstract
The utility model discloses a molding fixing device for a lead stopping block for a medical accelerator. The utility model comprises a supporting plate of a lead block (1) and a pressing plate (2), wherein, four corner parts of the supporting plate of the lead block (1) are respectively hinged with a bottom foot of a supporting screw rod (3) in a rotary mode; the upper part of the supporting screw rod (3) is provided with an adjusting nut (4) supporting the pressing plate (2); the supporting screw rod (3) is matched with a locking nut (5) to lock the pressing plate. The utility model has the advantages of simple structure, convenient operation and use, precise molding for focal zones, and simple, direct and accurate positioning to ensure the reliability of treatment and the safety of a treatment course. The fixing device of the utility model can be used for accelerators, and can be used for the treatment with an X knife with one object with multifunction, reducing use cost.
Description
This utility model belongs to radioactivity medical apparatus and instruments adnexa, is specifically related to a kind of medical accelerator that is used for, can be to the lead block clamping and fixing device of the accurate free posing of focal zone.
Medical accelerator has obtained using widely as a kind of radiation treatment apparatus of routine clinically, for countless terminally ill patients are alleviated and even removed slight illness, and more and more demonstrates its wide application prospect.At present,, adopt by a motor-driven multi-leaf optical grating (hurdle) surplus 80 and install, carry out accurate controlledly polygon moulding, location and treatment and obtained effect preferably in the world for solving accurate location and treatment problem to patient's focal zone.But this device costs an arm and a leg, and generally all more than hundreds of thousands unit, is difficult to promote and popularizes.Generally popular formative method still is more traditional now, porous lead supporting plate primary cutout assembling bolt fixed form, and the deficiency of this mode is the restriction of position, hole and quantity, is difficult to focus (especially making up focus) district is carried out accurate moulding and treatment.And anabolic process complexity, troublesome poeration.The design people has developed medical accelerator a kind of simple in structure, easy and simple to handle with lead block moulding fixture through concentrating on studies for many years and clinical practice for this reason, has obtained good effect.
It is a kind of simple in structure, easy for operation that the purpose of this utility model is to provide, and can carry out the medical accelerator lead block moulding fixture of accurate moulding to focal zone.
This utility model is achieved in that and comprises lead supporting plate and pressing plate.Four bights of lead supporting plate are hinged with the footing rotation of studdle respectively, and the top of studdle is provided with the adjusting nut that supports pressing plate, and by locking nut pressing plate is locked.
Because this utility model has adopted new structural design, and is not only simple in structure, and manipulates very convenient.Can accurately carry out moulding, improve therapeutic effect and the safety of accelerator greatly focal zone to focal zone.
Below in conjunction with accompanying drawing and embodiment this utility model is further described, but this utility model is not limited to shown in the accompanying drawing.
Accompanying drawing is an assembled state schematic perspective view of the present utility model.
As shown in drawings, this utility model is by lead supporting plate 1, pressing plate 2 and be supported between the two studdle 3 etc. and form.Four bights of lead supporting plate 1 are hinged with the footing rotation of studdle 3 respectively, and the top of studdle 3 is provided with adjusting nut 4, and adjusting nut 4 supports pressing plates 2, and cooperate pressing plate 2 lockings with locking nut 5.
Lead supporting plate of the present utility model is provided with the centre of location, and the shadow of it and accelerator coincides during work, so that can guarantee localized accuracy; Pressing plate 5 should be with the material that certain plasticity is arranged, so that it can more effectively compress movable lead, guarantees stable in operating process of lead after the moulding.Miscellaneous part all can adopt the employed conventional material in this area to make.
Work process of the present utility model is as follows:
1, at first according to the height of movable lead, regulates the position of adjusting nut, tighten the butterfly hold-down nut of a side, pressing plate one side and studdle are fixed as an integral body;
2, the studdle of reticulate pattern pressing plate by the band hinge changeed to a rollover, use movable lead then the focal zone moulding;
3, last, the reticulate pattern pressing plate is turned down, be pressed on the movable lead, with can device after the wing nut locking being used for radiation treatment focal zone to accelerator.
Characteristics of the present utility model:
1, simple in structure, with low cost, easy for operation;
2, accurate to the moulding of focal zone, locate simple and direct, accurate, thereby guaranteed the reliability for the treatment of, therapeutic process Security;
Used when 3, both can be used for accelerator radiotherapy, used when can be used for again the treatment of X cutter. One-object-many-purposes has reduced making Use cost.
This utility model can be with lower processing and fabricating cost, finishes accurate moulding to focal zone in simple and direct mode, has guaranteed the reliability and the safety of treatment, can substitute expensive multi-leaf optical grating (hurdle) lead block styling apparatus.Be easy to popularize, the performance of improving existing medical accelerator is had positive meaning.
