Fixing device for head tumor radiotherapy

Abstract

The invention discloses a fixing device for head tumor radiotherapy. The fixing device comprises a base, an arc-shaped plate and a first arc-shaped frame; the upper side of the base is provided with an arc-shaped groove; upper sides of two ends of the arc-shaped groove are each provided with an annular rotating support; the arc-shaped inner side face of the arc-shaped plate is fixedly provided with an arc-shaped bearing plate; the arc-shaped inner face of the bearing plate is fixedly provided with an arc-shaped fixing headrest; arc-shaped connecting rods are connected between the first arc-shaped frame and the arc-shaped plate; the arc-shaped inner side of the first arc-shaped frame is provided with a second arc-shaped frame; a plurality of springs are connected between the second arc-shaped frame and the first arc-shaped frame; and the arc-shaped inner side of the second arc-shaped frame is provided with an arc-shaped frame movable headrest. The fixing device is ingenious in design and simple in structure, realizes all-round fixation of the head of a patient, and can support rotation of the head of the patient when in use, thereby realizing adjustment of the posture of the head ofpatient; and the fixing device adapts to precise radiotherapy of tumors in different positions in the head, relieves the pain of the patient and the labor intensity of medical workers, and improves the comfort of the patient and the working efficiency of the medical workers.

Description

technical field [0001] The invention belongs to the technical field of radiotherapy auxiliary equipment, and in particular relates to a head tumor radiotherapy fixation device. Background technique [0002] Head tumors are one of the most common tumors, and patients need radiation therapy after surgery. Tumor radiation therapy refers to the use of radioactive isotope rays to accelerate the production of high-energy X-rays to kill tumor cells and treat benign and malignant tumors. Most malignant tumors of the head and neck can be effectively treated with radiotherapy, but radiotherapy for the head and neck requires high positioning of the radiotherapy position, so the patient's head needs to be fixed during radiotherapy. During the treatment, it is necessary to accurately control the radiation exposure site to reduce damage to the normal tissues of the head. [0003] When radiotherapy is performed on the head of tumor patients, since the treatment process takes a certain am...

AI Technical Summary

Problems solved by technology

However, in addition to the conventional defects of insufficient applicability to different patients and discomfort for patients after fixation, the existing head immobilization devices sometimes need to change the position of the patient's head for more thorough radiotherapy of tumors, while traditional immobilization devices It is very inconvenient to adjust the position of the patient's head. The existing head fixation device for radiotherapy has a single function and cannot support the patient's head to adjust the angle according to the position of the tumor, that is, it cannot support the rotation of the head, which increases the pain and pain of the patient. The labor intensity of medical staff cannot guarantee the accuracy and comprehensiveness of radiotherapy
