Description
Technical Field
The invention relates to the technical field of head fixing for tumor radiation, in particular to a head fixing device for tumor radiation.
Background
Tumor radiotherapy is a local treatment method for treating tumors by using radiation. Radiation includes radioisotope generated alpha, beta, gamma rays, and x-rays, electron beams, proton beams, and other particle beams generated by various types of x-ray therapeutic machines or accelerators, and the like. About 70% of cancer patients require radiation therapy in the course of treatment of cancer, and about 40% of cancer can be radically treated with radiation therapy. The role and position of radiation therapy in tumor therapy are increasingly prominent, and radiation therapy has become one of the main means for treating malignant tumors.
Head tumors include tumors of the nervous system and head and neck. Nervous system tumors include (1) primary intracranial tumors of parenchymal cell origin of the nervous system, (2) primary intracranial tumors located intracranially, but not of brain parenchymal cell origin, metastatic tumors. The incidence of primary central nervous system tumors is about 5-10/10 ten thousand. Wherein glioma accounts for 40%, meningioma accounts for 15%, and auditory neuroma (schwannoma) accounts for about 8%. Malignant astrogliomas account for about 50% of gliomas. Common intracranial tumors in children are glioma and medulloblastoma. Head and neck tumors include three major parts of neck tumors, otorhinolaryngological tumors, and oral, maxillofacial tumors. Neck tumors belong to common surgery in comprehensive hospitals, and thyroid tumors are more common; tumors of otorhinolaryngology commonly include laryngeal carcinoma, paranasal sinus carcinoma and the like; oral, maxillofacial tumors are common in various oral cancers, such as tongue cancer, gum cancer, cheek cancer, and the like. Thus, tumors that occur in the head, which are of many primary sites and pathological types, are the first part of the systemic tumor. In addition, the important organs of the head are concentrated, the anatomical relationship is complex, and the radiation therapy is an important treatment mode of head tumors.
When the tumor growing on the head needs to be treated by radiation, in order to ensure the stability of the head of a patient, a foam plastic plate is generally used for padding the head of the patient, so that the horizontal plane of the radiotherapy position is parallel to the treatment bed surface.
Currently, in the related technical solutions, due to the extremely high precision of radiotherapy, the precision of tumor on the head is within 3 mm, the position of the patient lying on the bed and the moving range of the radiating part need to be very small, and the following problems exist in the head of the patient by using the foam plastic plate pad: although the plastic board has a certain degree of plasticity, the plastic board can be extruded out to adapt to the radian of the head according to the weight of the head of a patient, but the plastic board is only in contact with the range of about one fourth of the head of the patient, and the rest three fourths of the positions of the plastic board cannot be fixed, so that the head is moved in the radiotherapy process of the patient due to frightening or other factors, and then the radiotherapy area exceeds the area of the patient which needs to be treated, thereby affecting the normal radiotherapy operation of the patient.
