Head ring holder structure of radiation brain surgery device

摘要

The present invention relates to a head ring holder structure of a radiation brain surgery apparatus for treating a brain tumor without cutting the skull, and a head ring holder for treating and fixing a head ring fixed to a head of a patient, The irradiation angle of the induction device for irradiating the photon beam with the rotation motion of the constant orbit can be rotated at an arbitrary three-dimensional angle, so that it is possible to irradiate the patient's lesion The intensive optimal dose is investigated so that the surrounding normal brain tissue is not damaged but only the target site (brain tumor, etc.) is solubilized and effective treatment is performed. That is to say, the head ring holder 3 is fastened to the inner side of the support ring 2 directly adjoining to the support plate 1 with the fastening plate 6 and the outer periphery of the head ring holder 3 rotates the driven gear 4 The horizontal moving bar 9 which is rotated by the driven gear 5 engaged with the moving gear 5 and engaged with the bottom surface of the supporting plate 1 horizontally moves along the fixed guide bar 11 with the horizontal adjusting bar 10, The upper part of the support plate 13 fixed to the table 14 is horizontally moved along the fixing guide 11 and the upper part of the support plate 13 is fixed to the table 14, And the head ring holder structure of the radiation therapy apparatus is characterized in that the height of the head ring holder is controlled by the height of the head ring holder.
