A precise positioning device for radiation therapy for body and head and neck tumors

Abstract

The present application provides a precise positioning device for radiotherapy for body and head and neck tumors, comprising a support component, wherein a positioning device is arranged above the support component, and the positioning device comprises a body positioning component and a head positioning component, wherein the positioning device is connected to the support component; wherein a limiting plate is provided within the support component, a limiting groove is formed at the position of the body positioning component corresponding to the limiting plate, wherein a bolt is inserted into the limiting plate, wherein the body positioning component is connected to the support component and the limiting plate interacts with the limiting groove, and wherein the bolt is removable and, after insertion, interacts with the limiting plate to limit the body positioning component;The device belongs to the technical field of medical radiotherapy aids. By forming bores within the limiting plate and inserting the bolt when the limiting groove within the body positioning component is in contact with the limiting plate, the bolt can be used for the temporary fixation of the body positioning component. This prevents positional deviations due to restoring forces, allowing the fixation process to be easily performed by a single person and significantly increasing the efficiency of the fixation operation of the radiotherapy positioning device.
