Abstract
The invention relates to a head three-dimensional precise positioning device for accelerator, which comprises an adapter rack for matching an accelerator treating head, a headstock with a shaft bearing at the center, one end of the headstock is connected with the adapter rack, the inner ring of the shaft bearing is provided with a fixing device for securing the tumor position on human head onto the bearing center. After the adapter rack, headstock and accelerator treating heads are mounted, the bearing center axis is aligned with the pendulum shaft of the accelerator, thus the therapeutic accuracy of the accelerator can be guaranteed during the treatment process.
Description
Technical field
The present invention relates to treatment and use accelerator, be specifically related to the accelerator three-dimensional accurate positioning device of head.
Prior art
The navigation system of existing accelerator mainly is arranged on the therapeutic bed, the treatment head of accelerator is installed on the framework of a band rotating shaft, treatment head along with the rotation of rotating shaft around rotation axis oscillating, the ray that the rotating shaft of framework and accelerator send is vertically intersected on a focus (O), during treatment, only need place focus (O) to locate to carry out irradiation treatment patient's focus gets final product, yet, because the treatment head is very heavy, support its framework easy deformation, when especially the treatment head was swung in therapeutic process, the framework easy deformation was difficult to guarantee that the focal position is constant, greatly influence treatment precision.
Summary of the invention
What the present invention will solve is existing accelerator cannot say for sure to demonstrate,prove the treatment precision because of framework is yielding in therapeutic process technical problem.
In order to solve above technical problem, the technical scheme that the present invention takes is:
A kind of accelerator three-dimensional accurate positioning device of head, it is characterized in that, comprise can with the matched adapter rack of accelerator treatment head and the middle headstock that is provided with bearing, one end of the headstock is connected with adapter rack, the internal ring of bearing is provided with the fixed mechanism that the knub position of human body head can be fixed on bearing centre point position, overlaps on the central shaft of the described bearing in the matched back of described adapter rack, the headstock and accelerator treatment head and the balance staff of accelerator.
Also be provided with headstock contiguous block between the described adapter rack and the headstock, this headstock contiguous block is provided with distance adjusting mechanism, the distance between the central point of scalable adapter rack and bearing.
Described fixed mechanism comprises the two equidistant ordinate guide rail and the two horizontal line guide rails vertical with two ordinate guide rails and that guide rail is connected that are parallel to each other and arrive between the central point of bearing, fixedly connected with the internal ring of bearing respectively in the end of two ordinate guide rails, one of two horizontal line guide rails be provided with can with the headrest support of therapeutic bed fixedly connected be connected slide block, another root is provided with the grip slide of band head clamp mechanism.
Also be provided with laser positioning mechanism on the described headstock.
After having adopted technique scheme, after accelerator treatment head connects above-mentioned positioner, carried out relative fixed owing to will speed up the focus of device lonizing radiation and rotating shaft, the directions of rays that makes the accelerator lonizing radiation is all the time on the central point of bearing, only need human body tumour cell is fixed on the central point of bearing and can guarantee the treatment precision of accelerator in therapeutic process, solved existing accelerator cannot say for sure to demonstrate,prove the treatment precision because of framework is yielding in therapeutic process technical problem.
