Radiotherapy head and neck positioning apparatus

Abstract

The invention discloses radiotherapy head and neck positioning apparatus. The apparatus comprises a U-shaped plate frame, wherein the upper end of the U-shaped plate frame is provided with a cylinder,the cylinder is composed of a first semi-cylinder and a second semi-cylinder, the outer sides of two ends of the first semi-cylinder and the second semi-cylinder are provided with semi-annular guiderails, the outer sides of the middles of the first semi-cylinder and the second semi-cylinder are provided with semi-annular gear rings, the inner side of the middle of the U-shaped plate frame is equipped with a geared motor, an output shaft of the geared motor is connected with a gear, the opposite surfaces of the first semi-cylinder and the second semi-cylinder are provided with T-shaped grooves for accommodating the body of a patient, the middles of one ends of the opposite surfaces of the first semi-cylinder and the second semi-cylinder are provided with semicircle-shaped grooves, and thesemicircle-shaped grooves constitute a circle-shaped through hole for accommodating the neck of the patient. The apparatus realizes the head and neck positioning in radiotherapy by fixing the body ofthe patient, a rotating supporting positioning structure enables the patient to rotate, the adjustment positioning of the head and neck posture of the patient is realized to adapt to the precise radiotherapy of tumors in different positions on the head, and thereby the apparatus is practical and convenient.

Description

technical field [0001] The invention belongs to the technical field of radiotherapy auxiliary equipment, and in particular relates to a head and neck positioning device for radiotherapy. 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 ...

AI Technical Summary

Problems solved by technology

In order to perform radiotherapy on the tumor more thoroughly, it is necessary to change the position and angle of the patient's head and neck. However, traditional radiotherapy fixtures cannot adjust the position and angle of the patient's head and neck, and the angle of the patient's head and neck cannot be adjusted according to the position of the tumor. It cannot drive the rotation and positioning of the head and neck, which increases the pain of the patient and the labor intensity of the medical staff, and cannot guarantee the accuracy and comprehensiveness of radiotherapy
